<P>
Command-Line Name:<B>-autoclear</B><BR>

Database Name: <B>autoClear</B><BR>

Database Class: <B>AutoClear</B>
<P>
A boolean value which specifies whether the first
keypress in a cell will delete whatever text was
previously there. Defaults to 0.
<P>
Command-Line Name:<B>-bordercursor</B><BR>

Database Name: <B>borderCursor</B><BR>

Database Class: <B>Cursor</B>
<P>
Specifies the name of the cursor to show when over
borders, a visual indication that interactive
resizing is allowed (it is thus affect by the value
of -resizeborders). Defaults to <I>crosshair</I>.
<P>
Command-Line Name:<B>-borderwidth</B> <B>or</B> <B>-bd</B><BR>

Database Name: <B>borderWidth</B><BR>

Database Class: <B>BorderWidth</B>
<P>
Specifies a non-negative pixel value or list of
values indicating the width of the 3-D border to
draw on interior table cells (if such a border is
being drawn; the <B>relief</B> option typically determines
this). If one value is specified, a rectangle of
this width will be drawn. If two values are specified,
then only the left and right edges of the
cell will have borders. If four values are specified,
then the values correspond to the {left right
top bottom} edges. This can be overridden by the a
tag's borderwidth option. It can also be affected
by the defined <B>-drawmode</B> for the table. Each value
in the list must have one of the forms acceptable
to <B>Tk_GetPixels</B>.
<P>
Command-Line Name:<B>-browsecommand</B> <B>or</B> <B>-browsecmd</B>
Database Name: <B>browseCommand</B><BR>

Database Class: <B>BrowseCommand</B>
<P>
Specifies a command which will be evaluated anytime
the active cell changes. It uses the %-substition
model described in COMMAND SUBSTITUTION below.
<P>
Command-Line Name:<B>-cache</B><BR>

Database Name: <B>cache</B><BR>

Database Class: <B>Cache</B>
<P>
A boolean value that specifies whether an internal
cache of the table contents should be kept. This
greatly enhances speed performance when used with
<B>-command</B> but uses extra memory. Can maintain state
when both <B>-command</B> and <B>-variable</B> are empty. The
cache is automatically flushed whenever the value
of <B>-cache</B> or <B>-variable</B> changes, otherwise you have
to explicitly call <B>clear</B> on it. Defaults to off.
<P>
Command-Line Name:<B>-colorigin</B><BR>

Database Name: <B>colOrigin</B><BR>

Database Class: <B>Origin</B>
<P>
Specifies what column index to interpret as the
leftmost column in the table. This value is used
for user indices in the table. Defaults to 0.
<P>
Command-Line Name:<B>-cols</B><BR>

Database Name: <B>cols</B><BR>

Database Class: <B>Cols</B>
<P>
Number of cols in the table. Defaults to 10.
<P>
Command-Line Name:<B>-colseparator</B><BR>

Database Name: <B>colSeparator</B><BR>

Database Class: <B>Separator</B>
<P>
Specifies a separator character that will be interpreted
as the column separator when cutting or
pasting data in a table. By default, columns are
separated as elements of a tcl list.
<P>
Command-Line Name:<B>-colstretchmode</B><BR>

Database Name: <B>colStretchMode</B><BR>

Database Class: <B>StretchMode</B>
<P>
Specifies one of the following stretch modes for
columns to fill extra allocated window space:
<B>none</B> Columns will not stretch to fill the
assigned window space. If the columns are
too narrow, there will be a blank space at
the right of the table. This is the
default.
<P>
<B>unset</B> Only columns that do not have a specific
width set will be stretched.

<DL>

<DT><B>all</B> </DT></DT>
<DD>   All columns will be stretched by the same
number of pixels to fill the window space
allocated to the table. This mode can
interfere with interactive border resizing
which tries to force column width.
</DD>
</DL>
<P>
<B>last</B> The last column will be stretched to fill
the window space allocated to the table.
<P>
<B>fill</B> (only valid for <B>-rowstretch</B> currently)
The table will get more or less columns
according to the window space allocated to
the table. This mode has numerous quirks
and may disappear in the future.
<P>
Command-Line Name:<B>-coltagcommand</B><BR>

Database Name: <B>colTagCommand</B><BR>

Database Class: <B>TagCommand</B>
<P>
Provides the name of a procedure that will be evaluated
by the widget to determine the tag to be used
for a given column. When displaying a cell, the
table widget will first check to see if a tag has
been defined using the <B>tag</B> <B>col</B> widget method. If
no tag is found, it will evaluate the named procedure
passing the column number in question as the
sole argument. The procedure is expected to return
the name of a tag to use, or a null string. Errors
occuring during the evaluation of the procedure, or
the return of an invalid tag name are silently
ignored.
<P>
Command-Line Name:<B>-colwidth</B><BR>

Database Name: <B>colWidth</B><BR>

Database Class: <B>ColWidth</B>
<P>
Default column width, interpreted as characters in
the default font when the number is positive, or
pixels if it is negative. Defaults to 10.
<P>
Command-Line Name:<B>-command</B><BR>

Database Name: <B>command</B><BR>

Database Class: <B>Command</B>
<P>
Specified a command to use as a procedural
interface to cell values. If <B>-usecommand</B> is true,
this command will be used instead of any reference
to the <B>-variable</B> array. When retrieving cell values,
the return value of the command is used as the
value for the cell. It uses the %-substition model
described in COMMAND SUBSTITUTION below.
<P>
Command-Line Name:<B>-drawmode</B><BR>

Database Name: <B>drawMode</B><BR>

Database Class: <B>DrawMode</B>
<P>
Sets the table drawing mode to one of the following
options:
<P>
<B>slow</B> The table is drawn to an offscreen pixmap
using the Tk bordering functions (doublebuffering).
This means there will be no
flashing, but this mode is slow for larger
tables.
<P>
<B>compatible</B><BR>

The table is drawn directly to the screen
using the Tk border functions. It is
faster, but the screen may flash on update.
This is the default.
<P>
<B>fast</B> The table is drawn directly to the screen
and the borders are done with fast X calls,
so they are always one pixel wide only. As
a side effect, it restricts <B>-borderwidth</B> to
a range of 0 or 1. This mode provides best
performance for large tables, but can flash
on redraw and is not 100% Tk compatible on
the border mode.
<P>
<B>single</B> The table is drawn to the screen as in fast
mode, but only single pixel lines are drawn
(not square borders).
<P>
Command-Line Name:<B>-flashmode</B><BR>

Database Name: <B>flashMode</B><BR>

Database Class: <B>FlashMode</B>
<P>
A boolean value which specifies whether cells
should flash when their value changes. The table
tag <B>flash</B> will be applied to these cells for the
duration specified by <B>-flashtime</B>. Defaults to 0.
<P>
Command-Line Name:<B>-flashtime</B><BR>

Database Name: <B>flashTime</B><BR>

Database Class: <B>FlashTime</B>
<P>
The amount of time, in 1/4 second increments, for
which a cell should flash when its value has
changed. <B>-flashmode</B> must be on. Defaults to 2.
<P>
Command-Line Name:<B>-height</B><BR>

Database Name: <B>height</B><BR>

Database Class: <B>Height</B>
<P>
Specifies the desired height for the window, in
rows. If zero or less, then the desired height for
the window is made just large enough to hold all
the rows in the table. The height can be further
limited by <B>-maxheight</B>.
<P>
Command-Line Name:<B>-invertselected</B><BR>

Database Name: <B>invertSelected</B><BR>

Database Class: <B>InvertSelected</B>
<P>
Specifies whether the foreground and background of
an item should simply have their values swapped
instead of merging the <I>sel</I> tag options when the
cell is selected. Defaults to 0 (merge <I>sel</I> tag).
<P>
Command-Line Name:<B>-ipadx</B><BR>

Database Name: <B>ipadX</B><BR>

Database Class: <B>Pad</B>
<P>
A pixel value specifying the internal offset X
padding for text in a cell. This value does not
grow the size of the cell, it just causes the text
to be drawn further from the cell border. It only
affects one side (depending on anchor). Defaults
to 0. See <B>-padx</B> for an alternate padding style.
<P>
Command-Line Name:<B>-ipady</B><BR>

Database Name: <B>ipadY</B><BR>

Database Class: <B>Pad</B>
<P>
A pixel value specifying the internal offset Y
padding for text in a cell. This value does not
grow the size of the cell, it just causes the text
to be drawn further from the cell border. It only
affects one side (depending on anchor). Defaults
to 0. See <B>-pady</B> for an alternate padding style.
<P>
Command-Line Name:<B>-maxheight</B><BR>

Database Name: <B>maxHeight</B><BR>

Database Class: <B>MaxHeight</B>
<P>
The max height in pixels that the window will
request. Defaults to 600.
<P>
Command-Line Name:<B>-maxwidth</B><BR>

Database Name: <B>maxWidth</B><BR>

Database Class: <B>MaxWidth</B>
<P>
The max width in pixels that the window will
request. Defaults to 800.
<P>
Command-Line Name:<B>-multiline</B><BR>

Database Name: <B>multiline</B><BR>

Database Class: <B>Multiline</B>
<P>
Specifies the default setting for the multiline tag
option. Defaults to 1.
<P>
Command-Line Name:<B>-padx</B><BR>

Database Name: <B>padX</B><BR>

Database Class: <B>Pad</B>
<P>
A pixel value specifying the offset X padding for a
cell. This value causes the default size of the
cell to increase by two times the value (one for
each side), unless a specific pixel size is chosen
for the cell with the <B>width</B> command. This will
force an empty area on the left and right of each
cell edge. This padding affects all types of data
in the cell. Defaults to 0. See <B>-ipadx</B> for an
alternate padding style.
<P>
Command-Line Name:<B>-pady</B><BR>

Database Name: <B>padY</B><BR>

Database Class: <B>Pad</B>
<P>
A pixel value specifying the offset Y padding for a
cell. This value causes the default size of the
cell to increase by two times the value (one for
each side), unless a specific pixel size is chosen
for the cell with the <B>height</B> command. This will
force an empty area on the top and bottom of each
cell edge. This padding affects all types of data
in the cell. Defaults to 0. See <B>-ipadx</B> for an
alternate padding style.
<P>
Command-Line Name:<B>-resizeborders</B><BR>

Database Name: <B>resizeBorders</B><BR>

Database Class: <B>ResizeBorders</B>
<P>
Specifies what kind of interactive border resizing
to allow, must be one of row, col, both (default)
or none.
<P>
Command-Line Name:<B>-rowheight</B><BR>

Database Name: <B>rowHeight</B><BR>

Database Class: <B>RowHeight</B>
<P>
Default row height, interpreted as lines in the
default font when the number is positive, or pixels
if it is negative. Defaults to 1.
<P>
Command-Line Name:<B>-roworigin</B><BR>

Database Name: <B>rowOrigin</B><BR>

Database Class: <B>Origin</B>
<P>
Specifies what row index to interpret as the topmost
row in the table. This value is used for user
indices in the table. Defaults to 0.
<P>
Command-Line Name:<B>-rows</B><BR>

Database Name: <B>rows</B><BR>

Database Class: <B>Rows</B>
<P>
Number of rows in the table. Defaults to 10.
<P>
Command-Line Name:<B>-rowseparator</B><BR>

Database Name: <B>rowSeparator</B><BR>

Database Class: <B>Separator</B>
<P>
Specifies a separator character that will be interpreted
as the row separator when cutting or pasting
data in a table. By default, rows are separated as
tcl lists.
<P>
Command-Line Name:<B>-rowstretchmode</B><BR>

Database Name: <B>rowStretchMode</B><BR>

Database Class: <B>StretchMode</B>
<P>
Specifies the stretch modes for rows to fill extra
allocated window space. See <B>-colstretchmode</B> for
valid options.
<P>
Command-Line Name:<B>-rowtagcommand</B><BR>

Database Name: <B>rowTagCommand</B><BR>

Database Class: <B>TagCommand</B>
<P>
Provides the name of a procedure that can evaluated
by the widget to determine the tag to be used for a
given row. The procedure must be defined by the
user to accept a single argument (the row number),
and return a tag name or null string. This operates
in a similar manner as <B>-coltagcommand</B>, except
that it applies to row tags.
<P>
Command-Line Name:<B>-selectioncommand</B> <B>or</B> <B>-selcmd</B>
Database Name: <B>selectionCommand</B><BR>

Database Class: <B>SelectionCommand</B>
<P>
Specifies a command to evaluate when the selection
is retrieved from a table via the selection mechanism
(ie: evaluating &laquo;<B>selection</B> <B>get</B>"). The return
value from this command will become the string
passed on by the selection mechanism. It uses the
%-substition model described in COMMAND SUBSTITUTION
below. If an error occurs, a Tcl background
error is generated and nothing is returned.
<P>
Command-Line Name:<B>-selectmode</B><BR>

Database Name: <B>selectMode</B><BR>

Database Class: <B>SelectMode</B>
<P>
Specifies one of several styles for manipulating
the selection. The value of the option may be
arbitrary, but the default bindings expect it to be
either <B>single</B>, <B>browse</B>, <B>multiple</B>, or <B>extended</B>; the
default value is <B>browse</B>. These styles are like
those for the Tk listbox, except expanded for 2
dimensions.
<P>
Command-Line Name:<B>-selecttitle</B><BR>

Database Name: <B>selectTitles</B><BR>

Database Class: <B>SelectTitles</B>
<P>
Specifies whether title cells should be allowed in
the selection. Defaults to 0 (disallowed).
<P>
Command-Line Name:<B>-selecttype</B><BR>

Database Name: <B>selectType</B><BR>

Database Class: <B>SelectType</B>
<P>
Specifies one of several types of selection for the
table. The value of the option may be one of <B>row</B>,
<B>col</B>, <B>cell</B>, or <B>both</B> (meaning <B>row</B> <B>&amp;&amp;</B> <B>col</B>); the
default value is <B>cell</B>. These types define whether
an entire row/col is affected when a cell's selection
is changed (set or clear).
<P>
Command-Line Name:<B>-sparsearray</B><BR>

Database Name: <B>sparseArray</B><BR>

Database Class: <B>SparseArray</B>
<P>
A boolean value that specifies whether an associated
Tcl array should be kept as a sparse array (1,
the default) or as a full array (0). If true, then
cell values that are empty will be deleted from the
array (taking less memory). If false, then all
values in the array will be maintained.
<P>
Command-Line Name:<B>-state</B><BR>

Database Name: <B>state</B><BR>

Database Class: <B>State</B>

<DL>

<DT>Specifies one of two states for the entry: </DT></DT>
<DD><B>normal</B>
or <B>disabled</B>. If the table is disabled then the
value may not be changed using widget commands and
no insertion cursor will be displayed, even if the
input focus is in the widget. Also, all insert or
delete methods will be ignored. Defaults to <B>normal</B>.
</DD>
</DL>
<P>
Command-Line Name:<B>-titlecols</B><BR>

Database Name: <B>titleCols</B><BR>

Database Class: <B>TitleCols</B>
<P>
Number of columns to use as a title area. Defaults
to 0.
<P>
Command-Line Name:<B>-titlerows</B><BR>

Database Name: <B>titleRows</B><BR>

Database Class: <B>TitleRows</B>
<P>
Number of rows to use as a title area. Defaults to
0.
<P>
Command-Line Name:<B>-usecommand</B><BR>

Database Name: <B>useCommand</B><BR>

Database Class: <B>UseCommand</B>
<P>
A boolean value which specifies whether to use the
<B>command</B> option. This value sets itself to zero if
<B>command</B> is used and returns an error. Defaults to
1 (will use <B>command</B> if specified).
<P>
Command-Line Name:<B>-validate</B><BR>

Database Name: <B>validate</B><BR>

Database Class: <B>Validate</B>
<P>
A boolean specifying whether validation should
occur for the active buffer. Defaults to 0.
<P>
Command-Line Name:<B>-validatecommand</B> <B>or</B> <B>-vcmd</B>
Database Name: <B>validateCommand</B><BR>

Database Class: <B>ValidateCommand</B>
<P>
Specifies a command to execute when the active cell
is edited. This command is expected to return a
Tcl boolean. If it returns true, then it is
assumed the new value is OK, otherwise the new
value is rejected (the edition will not take
place). Errors in this command are handled in the
background. It uses the %-substition model
described in COMMAND SUBSTITUTION below.
<P>
Command-Line Name:<B>-variable</B><BR>

Database Name: <B>variable</B><BR>

Database Class: <B>Variable</B>
<P>
Global Tcl array variable to attach to the table's
C array. It will be created if it doesn't already
exist or is a simple variable. Keys used by the
table in the array are of the form <I>row</I>,<I>col</I> for
cells and the special key <I>active</I> which contains the
value of the active cell buffer. The Tcl array is
managed as a sparse array (the table doesn't
require all valid indices have values). No stored
value for an index is equivalent to the empty
string, and clearing a cell will remove that index
from the Tcl array, unless the <B>-sparsearray</B> options
is set to 0.
<P>
Command-Line Name:<B>-width</B><BR>

Database Name: <B>width</B><BR>

Database Class: <B>Width</B>
<P>
Specifies the desired width for the window, in
columns. If zero or less, then the desired width
for the window is made just large enough to hold
all the columns in the table. The width can be
further limited by <B>-maxwidth</B>.
<P>
Command-Line Name:<B>-wrap</B><BR>

Database Name: <B>wrap</B><BR>

Database Class: <B>Wrap</B>
<P>
Specifies the default wrap value for tags.
Defaults to 0.<BR>

_________________________________________________________________

<H2><A NAME="sect4" HREF="#toc4"><B>Description</B></A></H2>

<P>
The <B>table</B> command creates a 2-dimensional grid of cells.
The table can use a Tcl array variable or Tcl command for
data storage and retrieval. The widget has an active
cell, the contents of which can be edited (when the state
is normal). The widget supports a default style for the
cells and also multiple <I>tags</I>, which can be used to change
the style of a row, column or cell (see TAGS for details).
A cell <I>flash</I> can be set up so that changed cells will
change color for a specified amount of time ("blink").
Cells can have embedded images or windows, as described in
TAGS and &laquo;EMBEDDED WINDOWS&raquo; respectively.
<P>
One or more cells may be selected as described below. If
a table is exporting its selection (see <B>-exportselection</B>
option), then it will observe the standard X11 protocols
for handling the selection. See THE SELECTION for
details.
<P>
It is not necessary for all the cells to be displayed in
the table window at once; commands described below may be
used to change the view in the window. Tables allow
scrolling in both directions using the standard <B>-xscrollcommand</B>
and <B>-yscrollcommand</B> options. They also support
scanning, as described below.
<P>
In order to obtain good performance, the table widget supports
multiple drawing modes, two of which are fully Tk
compatible.

<H2><A NAME="sect5" HREF="#toc5"><B>Initialization</B></A></H2>

<P>
When the <B>table</B> command is loaded into an interpreter, a
built-in Tcl command, <B>tkTableInit</B>, is evaluated. This
will search for the appropriate table binding init file to
load. The directories searched are those in <I>$tcl</I><B>_</B><I>pkgPath</I>,
both with Tktable(version) appended and without,
<I>$tk</I><B>_</B><I>library</I> and <I>[pwd]</I> (the current directory). You can
also define an <I>$env(TK</I><B>_</B><I>TABLE</I><B>_</B><I>LIBRARY)</I> to head this search
list. By default, the file searched for is called
<B>tkTable.tcl</B>, but this can be overridden by setting
<I>$env(TK</I><B>_</B><I>TABLE</I><B>_</B><I>LIBRARY</I><B>_</B><I>FILE)</I>.
<P>
This entire init script can be overridden by providing
your own <B>tkTableInit</B> procedure before the library is
loaded.         Otherwise,        the       aforementioned
<I>env(TK</I><B>_</B><I>TABLE</I><B>_</B><I>LIBRARY)</I> variable will be set with the directory
in which <I>$env(TK</I><B>_</B><I>TABLE</I><B>_</B><I>LIBRARY</I><B>_</B><I>FILE)</I> was found.

<H2><A NAME="sect6" HREF="#toc6"><B>Indices</B></A></H2>

<P>
Many of the widget commands for tables take one or more
indices as arguments. An index specifies a particular
cell of the table, in any of the following ways:
<P>
<I>number,number</I><BR>

Specifies the cell as a numerical index of
row,col which corresponds to the index of the
associated Tcl array, where <B>-roworigin,-colorigin</B>
corresponds to the first cell in the
table (0,0 by default).

<DL>

<DT><B>active</B> </DT></DT>
<DD>     Indicates the cell that has the location cursor.
It is specified with the <B>activate</B> widget
command.
</DD>

<DT><B>anchor</B> </DT></DT>
<DD>     Indicates the anchor point for the selection,
which is set with the <B>selection</B> <B>anchor</B> widget
command.
</DD>
</DL>
<P>
<B>bottomright</B> Indicates the bottom-rightmost cell visible in
the table.

<DL>

<DT><B>end</B> </DT></DT>
<DD>        Indicates the bottom right cell of the table.
</DD>

<DT><B>origin</B> </DT></DT>
<DD>     Indicates the top-leftmost editable cell of
the table, not necessarily in the display.
This takes into account the user specified
origin and title area.
</DD>

<DT><B>topleft</B> </DT></DT>
<DD>    Indicates the top-leftmost editable cell visible
in the table (this excludes title cells).
</DD>

<DT><B>@</B><I>x</I><B>,</B><I>y</I> </DT></DT>
<DD>       Indicates the cell that covers the point in
the table window specified by <I>x</I> and <I>y</I> (in
pixel coordinates). If no cell covers that
point, then the closest cell to that point is
used.
</DD>
</DL>
<P>
In the widget command descriptions below, arguments named
<I>index</I>, <I>first</I>, and <I>last</I> always contain text indices in one
of the above forms.

<H2><A NAME="sect7" HREF="#toc7"><B>Tags</B></A></H2>

<P>
A tag is a textual string that is associated with zero or
more rows, columns or cells in a table. Tags may contain
arbitrary characters, but it is probably best to avoid
using names which look like indices to reduce coding confusion.
There may be any number of tags in a table, but
each row, column or cell can only have one tag associated
with it at a time. There are several permanent tags in
each table that can be configured by the user and will
determine the attributes for special cells:

<DL>

<DT><B>active</B> </DT></DT>
<DD>   This tag is given to the <I>active</I> cell
</DD>

<DT><B>flash</B> </DT></DT>
<DD>    If flash mode is on, this tag is given to
any recently edited cells.
</DD>

<DT><B>sel</B> </DT></DT>
<DD>      This tag is given to any selected cells.
</DD>

<DT><B>title</B> </DT></DT>
<DD>    This tag is given to any cells in the
title rows and columns. This tag has
<B>-state</B> <I>disabled</I> by default.
</DD>
</DL>
<P>
Tags control the way cells are displayed on the screen.
Where appropriate, the default for displaying cells is
determined by the options for the table widget. However,
display options may be associated with individual tags
using the ``<I>pathName</I> <B>tag</B> <B>configure</B>'' widget command. If a
cell, row or column has been tagged, then the display
options associated with the tag override the default display
style. The following options are currently supported
for tags:

<DL>

<DT><B>-anchor</B> <I>anchor</I></DT></DT>
<DD>
Anchor for item in the cell space.
</DD>

<DT><B>-background</B> or <B>-bg</B> <I>color</I></DT></DT>
<DD>
Background color of the cell.
</DD>

<DT><B>-borderwidth</B> or <B>-bd</B> <I>pixelList</I></DT></DT>
<DD>
Borderwidth of the cell, of the same format
for the table, but may also be empty to
inherit the default table borderwidth value
(the default).
</DD>

<DT><B>-font</B> <I>fontName</I></DT></DT>
<DD>
Font for text in the cell.
</DD>

<DT><B>-foreground</B> or <B>-fg</B> <I>color</I></DT></DT>
<DD>
Foreground color of the cell.
</DD>

<DT><B>-justify</B> <I>justify</I></DT></DT>
<DD>
How to justify multi-line text in a cell.
It must be one of <B>left</B>, <B>right</B>, or <B>center</B>.
</DD>

<DT><B>-image</B> <I>imageName</I></DT></DT>
<DD>
An image to display in the cell instead of
text.
</DD>

<DT><B>-multiline</B> <I>boolean</I></DT></DT>
<DD>
Whether to display text with newlines on
multiple lines.
</DD>

<DT><B>-relief</B> <I>relief</I></DT></DT>
<DD>
The relief for the cell.
</DD>

<DT><B>-showtext</B> <I>boolean</I></DT></DT>
<DD>
Whether to show the text over an image.
</DD>

<DT><B>-state</B> <I>state</I></DT></DT>
<DD>
The state of the cell, to allow for certain
cells to be disabled. This prevents the
cell from being edited by the <I>insert</I> or
<I>delete</I> methods, but a direct <I>set</I> will not be
prevented.
</DD>

<DT><B>-wrap</B> <I>boolean</I></DT></DT>
<DD>
Whether characters should wrap in a cell
that is not wide enough.
</DD>
</DL>
<P>
A priority order is defined among tags based on creation
order (first created tag has highest default priority),
and this order is used in implementing some of the
tag-related functions described below. When a cell is
displayed, its properties are determined by the tags which
are assigned to it. The priority of a tag can be modified
by the ``<I>pathName</I> <B>tag</B> <B>lower</B>'' and ``<I>pathName</I> <B>tag</B> <B>raise</B>''
widget commands.
<P>
If a cell has several tags associated with it that define
the same display options (eg - a <B>title</B> cell with specific
<B>row</B> and <B>cell</B> tags), then the options of the highest priority
tag are used. If a particular display option hasn't
been specified for a particular tag, or if it is specified
as an empty string, then that option will not be used; the
next-highest-priority tag's option will be used instead.
If no tag specifies a particular display option, then the
default style for the widget will be used.
<P>
Images are used for display purposes only. Editing in
that cell will still be enabled and any querying of the
cell will show the text value of the cell, regardless of
the value of <B>-showtext</B>.

<H2><A NAME="sect8" HREF="#toc8"><B>Embedded</B> <B>Windows</B></A></H2>

<P>
There may be any number of embedded windows in a table
widget (one per cell), and any widget may be used as an
embedded window (subject to the usual rules for geometry
management, which require the table window to be the parent
of the embedded window or a descendant of its parent).
The embedded window's position on the screen will be
updated as the table is modified or scrolled, and it will
be mapped and unmapped as it moves into and out of the
visible area of the table widget. Each embedded window
occupies one cell's worth of space in the table widget,
and it is referred to by the index of the cell in the
table. Windows associated with the table widget are
destroyed when the table widget is destroyed.
<P>
Windows are used for display purposes only. A value still
exists for that cell, but will not be shown unless the
window is deleted in some way. If the window is destroyed
or lost by the table widget to another geometry manager,
then any data associated with it is lost (the cell it
occupied will no longer appear in <B>window</B> <B>names</B>).
<P>
When an embedded window is added to a table widget with
the window configure widget command, several configuration
options may be associated with it. These options may be
modified with later calls to the window configure widget
command. The following options are currently supported:

<DL>

<DT><B>-create</B> <I>script</I></DT></DT>
<DD>
NOT CURRENTLY SUPPORTED. Specifies a Tcl
script that may be evaluated to create the
window for the annotation. If no -window
option has been specified for this cell then
this script will be evaluated when the cell
is about to be displayed on the screen.
Script must create a window for the cell and
return the name of that window as its
result. If the cell's window should ever be
deleted, the script will be evaluated again
the next time the cell is displayed.
</DD>

<DT><B>-background</B> or <B>-bg</B> <I>color</I></DT></DT>
<DD>
Background color of the cell. If not specified,
it uses the table's default background.
</DD>

<DT><B>-borderwidth</B> or <B>-bd</B> <I>pixelList</I></DT></DT>
<DD>
Borderwidth of the cell, of the same format
for the table, but may also be empty to
inherit the default table borderwidth value
(the default).
</DD>

<DT><B>-padx</B> <I>pixels</I></DT></DT>
<DD>
As defined in the Tk options man page.
</DD>

<DT><B>-pady</B> <I>pixels</I></DT></DT>
<DD>
As defined in the Tk options man page.
</DD>

<DT><B>-relief</B> <I>relief</I></DT></DT>
<DD>
The relief to use for the cell in which the
window lies. If not specified, it uses the
table's default relief.
</DD>

<DT><B>-sticky</B> <I>sticky</I></DT></DT>
<DD>
Stickiness of the window inside the cell, as
defined by the <B>grid</B> command.
</DD>

<DT><B>-window</B> <I>pathName</I></DT></DT>
<DD>
Specifies the name of a window to display in
the annotation. It must exist before being
specified here.
</DD>
</DL>

<H2><A NAME="sect9" HREF="#toc9"><B>the</B> <B>Selection</B></A></H2>

<P>
Table selections are available as type STRING.    By
default, the value of the selection will be the values of
the selected cells in nested Tcl list form where each row
is a list and each column is an element of a row list.
You can change the way this value is interpreted by setting
the <B>-rowseparator</B> and <B>-colseparator</B> options. For
example, default Excel format would be to set <B>-rowseparator</B>
to &laquo;\n&raquo; and <B>-colseparator</B> to &laquo;\t". Changing these
values affects both how the table sends out the selection
and reads in pasted data, ensuring that the table should
always be able to cut and paste to itself. It is possible
to change how pastes are handled by editing the table
library procedure <B>tk_tablePasteHandler</B>. This might be
necessary if <B>-selectioncommand</B> is set.

<H2><A NAME="sect10" HREF="#toc10"><B>Row/Col</B> <B>Spanning</B></A></H2>

<P>
Individual cells can span multiple rows and/or columns.
This is done via the <B>spans</B> command (see below for exact
arguments). Cells in the title area that span are not
permitted to span beyond the title area, and will be constrained
accordingly. If the title area shrinks during a
configure, sanity checking will occur to ensure the above.
You may set spans on regular cells that extend beyond the
defined row/col area. These spans will not be constrained,
so that when the defined row/col area expands,
the span will expand with it.
<P>
When setting a span, checks are made as to whether the
span would overlap an already spanning or hidden cell.
This is an error and it not allowed. Spans can affect the
overall speed of table drawing, although not significantly.
If spans are not used, then there is no performance
loss.
<P>
Cells <I>hidden</I> by spanning cells still have valid data.
This will be seen during cut and paste operations that
involve hidden cells, or through direct access by a command
like <B>get</B> or <B>set</B>.
<P>
The drawing properties of spanning cells apply to only the
visual area of the cell. For example, if a cell is center
justified over 5 columns, then when viewing any portion of
those columns, it will appear centered in the visible
area. The non-visible column area will not be considered
in the centering calculations.

<H2><A NAME="sect11" HREF="#toc11"><B>Command</B> <B>Substitution</B></A></H2>

<P>
The various option based commands that the table supports
all support the familiar Tk %-substitution model (see <B>bind</B>
for more details). The following %-sequences are recognized
and substituted by the table widget:
<P>
<B>%c</B> For <B>SelectionCommand</B>, it is the maximum number of
columns in any row in the selection. Otherwise it is
the column of the triggered cell.

<DL>

<DT><B>%C</B> </DT></DT>
<DD>A convenience substitution for <I>%r</I>,<I>%c</I>.
</DD>

<DT><B>%i</B> </DT></DT>
<DD>For <B>SelectionCommand</B>, it is the total number of cells
in the selection. For <B>Command</B>, it is 0 for a read
(get) and 1 for a write (set). Otherwise it is the
current cursor position in the cell.
</DD>

<DT><B>%r</B> </DT></DT>
<DD>For <B>SelectionCommand</B>, it is the number of rows in the
selection. Otherwise it is the row of the triggered
cell.
</DD>
</DL>
<P>
<B>%s</B> For <B>ValidateCommand</B>, it is the current value of the
cell being validated. For <B>SelectionCommand</B>, it is
the default value of the selection. For <B>BrowseCommand</B>,
it is the index of the last active cell. For
<B>Command</B>, it is empty for reads (get) and the current
value of the cell for writes (set).

<DL>

<DT><B>%S</B> </DT></DT>
<DD>For <B>ValidateCommand</B>, it is the potential new value of
the cell being validated. For <B>BrowseCommand</B>, it is
the index of the new active cell.
</DD>
</DL>
<P>
<B>%W</B> The pathname to the window for which the command was
generated.

<H2><A NAME="sect12" HREF="#toc12"><B>Widget</B> <B>Command</B></A></H2>

<P>
The <B>table</B> command creates a new Tcl command whose name is
<I>pathName</I>. This command may be used to invoke various
operations on the widget. It has the following general
form:<BR>

<I>pathName</I> <I>option</I> ?<I>arg</I> <I>arg</I> <I>...</I>?<BR>

<I>Option</I> and the <I>arg</I>s determine the exact behavior of the
command.
<P>
The following commands are possible for <B>table</B> widgets:
<P>
<I>pathName</I> <B>activate</B> <I>index</I><BR>

Sets the active cell to the one indicated by <I>index</I>.
<P>
<I>pathName</I> <B>bbox</B> <I>first</I> ?<I>last</I>?<BR>

It returns the bounding box for the specified cell
(range) as a 4-tuple of x, y, width and height in
pixels. It clips the box to the visible portion,
if any, otherwise an empty string is returned.
<P>
<I>pathName</I> <B>border</B> <I>option</I> <I>args</I><BR>

This command is a voodoo hack to implement border
sizing for tables. This is normally called through
bindings, with the following as valid options:
<P>
<I>pathName</I> <B>border</B> <B>mark</B> <I>x</I> <I>y</I> ?<I>row|col</I>?
Records <I>x</I> and <I>y</I> and the row and/or column
border under that point in the table window,
if any; used in conjunction with later <B>border</B>
<B>dragto</B> commands. Typically this command
is associated with a mouse button press in
the widget. If <I>row</I> or <I>col</I> is not specified,
it returns a tuple of both border indices
(an empty item means no border). Otherwise,
just the specified item is returned.
<P>
<I>pathName</I> <B>border</B> <B>dragto</B> <I>x</I> <I>y</I><BR>

This command computes the difference between
its <I>x</I> and <I>y</I> arguments and the <I>x</I> and <I>y</I> arguments
to the last <B>border</B> <B>mark</B> command for
the widget. It then adjusts the previously
marked border by the difference. This command
is typically associated with mouse
motion events in the widget, to produce the
effect of interactive border resizing.
<P>
<I>pathName</I> <B>cget</B> <I>option</I><BR>

Returns the current value of the configuration
option given by <I>option</I>. <I>Option</I> may have any of the
values accepted by the <B>table</B> command.
<P>
<I>pathName</I> <B>clear</B> <I>option</I> ?<I>first</I>? ?<I>last</I>?<BR>

This command is a convenience routine to clear certain
state information managed by the table. <I>first</I>
and <I>last</I> represent valid table indices. If neither
are specified, then the command operates on the
whole table. The following options are recognized:
<P>
<I>pathName</I> <B>clear</B> <B>cache</B> ?<I>first</I>? ?<I>last</I>?
Clears the specified section of the cache,
if the table has been keeping one.
<P>
<I>pathName</I> <B>clear</B> <B>sizes</B> ?<I>first</I>? ?<I>last</I>?
Clears the specified row and column areas of
specific height/width dimensions. When just
one index is specified, for example <B>2,0</B>,
that is interpreted as row 2 <B>and</B> column 0.
<P>
<I>pathName</I> <B>clear</B> <B>tags</B> ?<I>first</I>? ?<I>last</I>?
Clears the specified area of tags (all row,
column and cell tags).
<P>
<I>pathName</I> <B>clear</B> <B>all</B> ?<I>first</I>? ?<I>last</I>?
Performs all of the above clear functions on
the specified area.
<P>
<I>pathName</I> <B>configure</B> ?<I>option</I>? ?<I>value</I> <I>option</I> <I>value</I> <I>...</I>?
Query or modify the configuration options of the
widget. If no <I>option</I> is specified, returns a list
describing all of the available options for <I>path</I><B>_N</B><I>ame</I>
(see <B>Tk_ConfigureInfo</B> for information on the
format of this list). If <I>option</I> is specified with
no <I>value</I>, then the command returns a list describing
the one named option (this list will be identical
to the corresponding sublist of the value
returned if no <I>option</I> is specified). If one or
more <I>option-value</I> pairs are specified, then the
command modifies the given widget option(s) to have
the given value(s); in this case the command
returns an empty string. <I>Option</I> may have any of
the values accepted by the <B>table</B> command.
<P>
<I>pathName</I> <B>curselection</B> ?<I>value</I>?<BR>

With no arguments, it returns the sorted indices of
the currently selected cells. Otherwise it sets
all the selected cells to the given value. The set
has no effect if there is no associated Tcl array
or the state is disabled.
<P>
<I>pathName</I> <B>curvalue</B> ?<I>value</I>?<BR>

If no value is given, the value of the cell being
edited (indexed by <B>active</B>) is returned, else it is
set to the given value.
<P>
<I>pathName</I> <B>delete</B> <I>option</I> <I>arg</I> ?<I>arg</I>?<BR>

This command is used to delete various things in a
table. It has several forms, depending on the
<I>option</I>:
<I>pathName</I> <B>delete</B> <B>active</B> <I>index</I> ?<I>index</I>?
Deletes text from the active cell. If only
one index is given, it deletes the character
after that index, otherwise it deletes from
the first index to the second. <I>index</I> can be
a number, <B>insert</B> or <B>end</B>.
<P>
<I>pathName</I> <B>delete</B> <B>cols</B> ?<I>switches</I>? <I>index</I> ?<I>count</I>?
Deletes <I>count</I> cols starting at (and including)
col <I>index</I>. The <I>index</I> will be constrained
to the limits of the tables. If
<I>count</I> is negative, it deletes cols to the
left. Otherwise it deletes cols to the
right. <I>count</I> defaults to 1 (meaning just
the column specified). At the moment, spans
are not adjusted with this action. Optional
switches are:

<DL>

<DT><B>-holddimensions</B></DT></DT>
<DD>
Causes the table cols to be unaffected
by the deletion (empty cols
may appear). By default the dimensions
are adjusted by <B>count</B>.
</DD>

<DT><B>-holdselection</B></DT></DT>
<DD>
Causes the selection to be maintained
on the absolute cells values.
Otherwise, the selection will be
cleared..
</DD>

<DT><B>-holdtags</B></DT></DT>
<DD>
Causes the tags specified by the <I>tag</I>
method to not move along with the
data. Also prevents specific widths
set by the <I>width</I> method from being
adjusted. By default, these tags
are properly adjusted.
</DD>

<DT><B>-holdwindows</B></DT></DT>
<DD>
Causes the embedded windows created
with the <I>window</I> method to not move
along with the data. By default,
these windows are properly adjusted.
</DD>

<DT><B>-keeptitles</B></DT></DT>
<DD>
Prevents title area cells from being
changed. Otherwise they are treated
just like regular cells and will
move as specified.
</DD>

<DT><B>--</B> </DT></DT>
<DD>    Signifies the end of the switches.
</DD>
</DL>
<P>
<I>pathName</I> <B>delete</B> <B>rows</B> ?<I>switches</I>? <I>index</I> ?<I>count</I>?
Deletes <B>count</B> rows starting at (and
including) row <B>index</B>. If <B>count</B> is negative,
it deletes rows going up. Otherwise it
deletes rows going down. The selection will
be cleared. The switches are the same as
those for column deletion.
<P>
<I>pathName</I> <B>get</B> <I>first</I> ?<I>last</I>?<BR>

Returns the value of the cells specified by the
table indices <I>first</I> and (optionally) <I>last</I> in a
list.
<P>
<I>pathName</I> <B>height</B> ?<I>row</I>? ?<I>value</I> <I>row</I> <I>value</I> <I>...</I>?
If no <I>row</I> is specified, returns a list describing
all rows for which a height has been set. If <B>row</B>
is specified with no value, it prints out the
height of that row in characters (positive number)
or pixels (negative number). If one or more
<I>row-value</I> pairs are specified, then it sets each
row to be that height in lines (positive number) or
pixels (negative number). If <I>value</I> is <I>default</I>,
then the row uses the default height, specified by
<B>-rowheight</B>.
<P>
<I>pathName</I> <B>hidden</B> ?<I>index</I>? ?<I>index</I> <I>...</I>?<BR>

When called without args, it returns all the <I>hidden</I>
cells (those cells covered by a spanning cell). If
one index is specified, it returns the spanning
cell covering that index, if any. If multiple
indices are specified, it returns 1 if all indices
are hidden cells, 0 otherwise.
<P>
<I>pathName</I> <B>icursor</B> ?<I>arg</I>?<BR>

With no arguments, prints out the location of the
insertion cursor in the active cell. With one
argument, sets the cursor to that point in the
string. 0 is before the first character, you can
also use <B>insert</B> or <B>end</B> for the current insertion
point or the end of the text. If there is no
active cell, or the cell or table is disabled, this
will return -1.
<P>
<I>pathName</I> <B>index</B> <I>index</I> ?<I>row|col</I>?<BR>

Returns the integer cell coordinate that corresponds
to <I>index</I> in the form row,col. If <B>row</B> or <B>col</B>
is specified, then only the row or column index is
returned.
<P>
<I>pathName</I> <B>insert</B> <I>option</I> <I>arg</I> <I>arg</I><BR>

This command is used to into various things into a
table. It has several forms, depending on the
<I>option</I>:
<P>
<I>pathName</I> <B>insert</B> <B>active</B> <I>index</I> <I>value</I>
The <I>value</I> is a text string which is inserted
at the <I>index</I> postion of the active cell.
The cursor is then positioned after the new
text. <I>index</I> can be a number, <B>insert</B> or <B>end</B>.
<P>
<I>pathName</I> <B>insert</B> <B>cols</B> ?<I>switches</I>? <I>index</I> ?<I>count</I>?
Inserts <B>count</B> cols starting at col <B>index</B>.
If <B>count</B> is negative, it inserts before the
specified col. Otherwise it inserts after
the specified col. The selection will be
cleared. The switches are the same as those
for column deletion.
<P>
<I>pathName</I> <B>insert</B> <B>rows</B> ?<I>switches</I>? <I>index</I> ?<I>count</I>?
Inserts <B>count</B> rows starting at row <B>index</B>.
If <B>count</B> is negative, it inserts before the
specified row. Otherwise it inserts after
the specified row. The selection will be
cleared. The switches are the same as those
for column deletion.
<P>
<I>pathName</I> <B>reread</B><BR>

Rereads the old contents of the cell back into the
editing buffer. Useful for a key binding when
&lt;Escape&gt; is pressed to abort the edit (a default
binding).
<P>
<I>pathName</I> <B>scan</B> <I>option</I> <I>args</I><BR>

This command is used to implement scanning on
tables. It has two forms, depending on <I>option</I>:
<P>
<I>pathName</I> <B>scan</B> <B>mark</B> <I>x</I> <I>y</I><BR>

Records <I>x</I> and <I>y</I> and the current view in the
table window; used in conjunction with
later <B>scan</B> <B>dragto</B> commands. Typically this
command is associated with a mouse button
press in the widget. It returns an empty
string.
<P>
<I>pathName</I> <B>scan</B> <B>dragto</B> <I>x</I> <I>y</I>.<BR>

This command computes the difference between
its <I>x</I> and <I>y</I> arguments and the <I>x</I> and <I>y</I> arguments
to the last <B>scan</B> <B>mark</B> command for the
widget. It then adjusts the view by 5 times
the difference in coordinates. This command
is typically associated with mouse motion
events in the widget, to produce the effect
of dragging the list at high speed through
the window. The return value is an empty
string.
<P>
<I>pathName</I> <B>see</B> <I>index</I><BR>

Adjust the view in the table so that the cell given
by <I>index</I> is positioned as the cell one off from top
left (excluding title rows and columns) if the cell
is not currently visible on the screen. The actual
cell may be different to keep the screen full.
<P>
<I>pathName</I> <B>selection</B> <I>option</I> <I>arg</I><BR>

This command is used to adjust the selection within
a table. It has several forms, depending on
<I>option</I>:
<P>
<I>pathName</I> <B>selection</B> <B>anchor</B> <I>index</I><BR>

Sets the selection anchor to the cell given
by <I>index</I>. The selection anchor is the end
of the selection that is fixed while dragging
out a selection with the mouse. The
index <B>anchor</B> may be used to refer to the
anchor cell.
<P>
<I>pathName</I> <B>selection</B> <B>clear</B> <I>first</I> ?<I>last</I>?
If any of the cells between <I>first</I> and <I>last</I>
(inclusive) are selected, they are deselected.
The selection state is not changed
for cells outside this range. <I>first</I> may be
specified as <B>all</B> to remove the selection
from all cells.
<P>
<I>pathName</I> <B>selection</B> <B>includes</B> <I>index</I>
Returns 1 if the cell indicated by <I>index</I> is
currently selected, 0 if it isn't.
<P>
<I>pathName</I> <B>selection</B> <B>set</B> <I>first</I> ?<I>last</I>?
Selects all of the cells in the range
between <I>first</I> and <I>last</I>, inclusive, without
affecting the selection state of cells outside
that range.
<P>
<I>pathName</I> <B>set</B> ?<I>row|col</I>? <I>index</I> ?<I>value</I>? ?<I>index</I> <I>value</I> <I>...</I>?
Sets the specified index to the associated value.
Table validation will not be triggered via this
method. If <B>row</B> or <B>col</B> precedes the list of
index/value pairs, then the value is assumed to be
a Tcl list whose values will be split and set into
the subsequent columns (if <B>row</B> is specified) or
rows (for <B>col</B>). For example, <B>set</B> <B>row</B> <B>2,3</B> <B>{2,3</B> <B>2,4</B>
<B>2,5}</B> will set 3 cells, from 2,3 to 2,5. The setting
of cells is silently bounded by the known
table dimensions.
<P>
<I>pathName</I> <B>spans</B> ?<I>index</I>? ?<I>rows,cols</I> <I>index</I> <I>rows,cols</I> <I>...</I>?
This command is used to manipulate row/col spans.
When called with no arguments, all known spans are
returned as a list of tuples of the form {index
span}. When called with only the <I>index</I>, the span
for that <I>index</I> only is returned, if any. Otherwise
an even number of <I>index</I> <I>rows,cols</I> pairs are used to
set spans. A span starts at the <I>index</I> and
continues for the specified number of rows and
cols. Negative spans are not supported. A span of
0,0 unsets any span on that cell. See EXAMPLES for
more info.
<P>
<I>pathName</I> <B>tag</B> option ?<I>arg</I> <I>arg</I> <I>...</I>?<BR>

This command is used to manipulate tags. The exact
behavior of the command depends on the <I>option</I> argument
that follows the <B>tag</B> argument. <I>cget</I>, <I>cell</I>,
and <I>row|col</I> complain about unknown tag names. The
following forms of the command are currently supported:
<P>
<I>pathName</I> <B>tag</B> <B>cell</B> <I>tagName</I> <I>?index</I> <I>...?</I>
With no arguments, prints out the list of
cells that use the <I>tag</I>. Otherwise it sets
the specified cells to use the named tag,
replacing any tag that may have been set
using this method before. If <I>tagName</I> is {},
the cells are reset to the default <I>tag</I>.
Tags added during -*tagcommand evaluation do
not register here. If <I>tagName</I> does not
exist, it will be created with the default
options.
<P>
<I>pathName</I> <B>tag</B> <B>cget</B> <I>tagName</I> <I>option</I>
This command returns the current value of
the option named <I>option</I> associated with the
tag given by <I>tagName</I>. <I>Option</I> may have any
of the values accepted by the <B>tag</B> <B>configure</B>
widget command.
<P>
<I>pathName</I> <B>tag</B> <B>col</B> <I>tagName</I> <I>?col</I> <I>...?</I>
With no arguments, prints out the list of
cols that use the <I>tag</I>. Otherwise it sets
the specified columns to use the named tag,
replacing any tag that may have been set
using this method before. If <I>tagName</I> is {},
the cols are reset to the default <I>tag</I>. Tags
added during -coltagcommand evaluation do
not register here. If <I>tagName</I> does not
exist, it will be created with the default
options.
<P>
<I>pathName</I> <B>tag</B> <B>configure</B> <I>tagName</I> ?<I>option</I>? ?<I>value</I>?
?<I>option</I> <I>value</I> <I>...</I>?<BR>

This command is similar to the <B>configure</B>
widget command except that it modifies
options associated with the tag given by
<I>tagName</I> instead of modifying options for the
overall table widget. If no <I>option</I> is specified,
the command returns a list describing
all of the available options for <I>tagName</I>
(see <B>Tk_ConfigureInfo</B> for information on the
format of this list). If <I>option</I> is specified
with no <I>value</I>, then the command returns
a list describing the one named option (this
list will be identical to the corresponding
sublist of the value returned if no <I>option</I>
is specified). If one or more <I>option-value</I>
pairs are specified, then the command modifies
the given option(s) to have the given
value(s) in <I>tagName</I>; in this case the command
returns an empty string. See TAGS
above for details on the options available
for tags.
<P>
<I>pathName</I> <B>tag</B> <B>delete</B> <I>tagName</I><BR>

Deletes a tag. No error if the tag does not
exist.
<P>
<I>pathName</I> <B>tag</B> <B>exists</B> <I>tagName</I><BR>

Returns 1 if the named tag exists, 0 otherwise.
<P>
<I>pathName</I> <B>tag</B> <B>includes</B> <I>tagName</I> <I>index</I>
Returns 1 if the specified index has the
named tag, 0 otherwise.
<P>
<I>pathName</I> <B>tag</B> <B>lower</B> <I>tagName</I> ?<I>belowThis</I>?
Lower the priority of the named tag. If
<I>belowThis</I> is not specified, then the tag's
priority is lowered to the bottom, otherwise
it is lowered to one below <I>belowThis</I>.
<P>
<I>pathName</I> <B>tag</B> <B>names</B> ?<I>pattern</I>?<BR>

If no pattern is specified, shows the names
of all defined tags. Otherwise the <I>pattern</I>
is used as a glob pattern to show only tags
matching that pattern. Tag names are
returned in priority order (highest priority
tag first).
<P>
<I>pathName</I> <B>tag</B> <B>raise</B> <I>tagName</I> ?<I>aboveThis</I>?
Raise the priority of the named tag. If
<I>aboveThis</I> is not specified, then the tag's
priority is raised to the top, otherwise it
is raised to one above <I>aboveThis</I>.
<P>
<I>pathName</I> <B>tag</B> <B>row</B> <I>tagName</I> ?<I>row</I> <I>...</I>?
With no arguments, prints out the list of
rows that use the <I>tag</I>. Otherwise it sets
the specified columns to use the named tag,
replacing any tag that may have been set
using this method before. If <I>tagName</I> is {},
the rows are reset to use the default tag.
Tags added during -rowtagcommand evaluation
do not register here. If <I>tagName</I> does not
exist, it will be created with the default
options.
<P>
<I>pathName</I> <B>validate</B> <I>index</I><BR>

Explicitly validates the specified index based on
the current <B>-validatecommand</B> and returns 0 or 1
based on whether the cell was validated.
<P>
<I>pathName</I> <B>width</B> ?<I>col</I>? ?<I>value</I> <I>col</I> <I>value</I> <I>...</I>?
If no <I>col</I> is specified, returns a list describing
all cols for which a width has been set. If <B>col</B> is
specified with no value, it prints out the width of
that col in characters (positive number) or pixels
(negative number). If one or more <I>col-value</I> pairs
are specified, then it sets each col to be that
width in characters (positive number) or pixels
(negative number). If <I>value</I> is <I>default</I>, then the
col uses the default width, specified by <B>-colwidth</B>.
<P>
<I>pathName</I> <B>window</B> option ?<I>arg</I> <I>arg</I> <I>...</I>?<BR>

This command is used to manipulate embedded windows.
The exact behavior of the command depends on
the <I>option</I> argument that follows the <B>window</B> argument.
The following forms of the command are currently
supported:
<P>
<I>pathName</I> <B>window</B> <B>cget</B> <I>index</I> <I>option</I>
This command returns the current value of
the option named <I>option</I> associated with the
window given by <I>index</I>. <I>Option</I> may have any
of the values accepted by the <B>window</B> <B>configure</B>
widget command.
<P>
<I>pathName</I> <B>window</B> <B>configure</B> <I>index</I> ?<I>option</I>? ?<I>value</I>?
?<I>option</I> <I>value</I> <I>...</I>?<BR>

This command is similar to the <B>configure</B>
widget command except that it modifies
options associated with the embedded window
given by <I>index</I> instead of modifying options
for the overall table widget. If no <I>option</I>
is specified, the command returns a list
describing all of the available options for
<I>index</I> (see <B>Tk_ConfigureInfo</B> for information
on the format of this list). If <I>option</I> is
specified with no <I>value</I>, then the command
returns a list describing the one named
option (this list will be identical to the
corresponding sublist of the value returned
if no <I>option</I> is specified). If one or more
<I>option-value</I> pairs are specified, then the
command modifies the given option(s) to have
the given value(s) in <I>index</I>; in this case
the command returns an empty string. See
EMBEDDED WINDOWS above for details on the
options available for windows.
<P>
<I>pathName</I> <B>window</B> <B>delete</B> <I>index</I> ?<I>index</I> <I>...</I>?
Deletes an embedded window from the table.
The associated window will also be deleted.
<P>
<I>pathName</I> <B>window</B> <B>move</B> <I>indexFrom</I> <I>indexTo</I>
Moves an embedded window from one cell to
another. If a window already exists in the
target cell, it will be deleted.
<P>
<I>pathName</I> <B>window</B> <B>names</B> ?<I>pattern</I>?<BR>

If no pattern is specified, shows the cells
of all embedded windows. Otherwise the <I>pat</I><B>_</B>t<I>ern</I>
is used as a glob pattern to show only
cells matching that pattern.
<P>
<I>pathName</I> <B>xview</B> <I>args</I><BR>

This command is used to query and change the horizontal
position of the information in the widget's
window. It can take any of the following forms:
<P>
<I>pathName</I> <B>xview</B><BR>

Returns a list containing two elements.
Each element is a real fraction between 0
and 1; together they describe the horizontal
span that is visible in the window. For
example, if the first element is .2 and the
second element is .6, 20% of the table's
text is off-screen to the left, the middle
40% is visible in the window, and 40% of the
text is off-screen to the right. These are
the same values passed to scrollbars via the
<B>-xscrollcommand</B> option.
<P>
<I>pathName</I> <B>xview</B> <I>index</I><BR>

Adjusts the view in the window so that the
column given by <I>index</I> is displayed at the
left edge of the window.
<P>
<I>pathName</I> <B>xview</B> <B>moveto</B> <I>fraction</I><BR>

Adjusts the view in the window so that <I>frac</I><B>_</B>t<I>ion</I>
of the total width of the table text is
off-screen to the left. <I>fraction</I> must be a
fraction between 0 and 1.
<P>
<I>pathName</I> <B>xview</B> <B>scroll</B> <I>number</I> <I>what</I>
This command shifts the view in the window
left or right according to <I>number</I> and <I>what</I>.
<I>Number</I> must be an integer. <I>What</I> must be
either <B>units</B> or <B>pages</B> or an abbreviation of
one of these. If <I>what</I> is <B>units</B>, the view
adjusts left or right by <I>number</I> character
units (the width of the <B>0</B> character) on the
display; if it is <B>pages</B> then the view
adjusts by <I>number</I> screenfuls. If <I>number</I> is
negative then characters farther to the left
become visible; if it is positive then
characters farther to the right become visible.
<P>
<I>pathName</I> <B>yview</B> <I>?args</I>?<BR>

This command is used to query and change the vertical
position of the text in the widget's window.
It can take any of the following forms:
<P>
<I>pathName</I> <B>yview</B><BR>

Returns a list containing two elements, both
of which are real fractions between 0 and 1.
The first element gives the position of the
table element at the top of the window, relative
to the table as a whole (0.5 means it
is halfway through the table, for example).
The second element gives the position of the
table element just after the last one in the
window, relative to the table as a whole.
These are the same values passed to scrollbars
via the <B>-yscrollcommand</B> option.
<P>
<I>pathName</I> <B>yview</B> <I>index</I><BR>

Adjusts the view in the window so that the
row given by <I>index</I> is displayed at the top
of the window.
<P>
<I>pathName</I> <B>yview</B> <B>moveto</B> <I>fraction</I><BR>

Adjusts the view in the window so that the
element given by <I>fraction</I> appears at the top
of the window. <I>Fraction</I> is a fraction
between 0 and 1; 0 indicates the first element
in the table, 0.33 indicates the element
one-third the way through the table,
and so on.
<P>
<I>pathName</I> <B>yview</B> <B>scroll</B> <I>number</I> <I>what</I>
This command adjusts the view in the window
up or down according to <I>number</I> and <I>what</I>.
<I>Number</I> must be an integer. <I>What</I> must be
either <B>units</B> or <B>pages</B>. If <I>what</I> is <B>units</B>,
the view adjusts up or down by <I>number</I> lines;
if it is <B>pages</B> then the view adjusts by <I>num</I><B>_</B>b<I>er</I>
screenfuls. If <I>number</I> is negative then
earlier elements become visible; if it is
positive then later elements become visible.

<H2><A NAME="sect13" HREF="#toc13"><B>Default</B> <B>Bindings</B></A></H2>

<P>
The initialization creates class bindings that give the
following default behaviour:

<DL>

<DT>[1] </DT></DT>
<DD>   Clicking Button-1 in a cell activates that cell.
Clicking into an already active cell moves the
insertion cursor to the character nearest the
mouse.
</DD>

<DT>[2] </DT></DT>
<DD>   Moving the mouse while Button-1 is pressed will
stroke out a selection area. Exiting while Button-1
is pressed causing scanning to occur on the
table along with selection.
</DD>

<DT>[3] </DT></DT>
<DD>   Moving the mouse while Button-2 is pressed causes
scanning to occur without any selection.
</DD>

<DT>[4] </DT></DT>
<DD>   Home moves the table to have the origin in view.
</DD>

<DT>[5] </DT></DT>
<DD>   End moves the table to have the <B>end</B> cell in view.
</DD>

<DT>[6] </DT></DT>
<DD>   Control-Home moves the table to the origin and
activates that cell.
</DD>

<DT>[7] </DT></DT>
<DD>   Control-End moves the table to the end and activates
that cell.
</DD>

<DT>[8] </DT></DT>
<DD>   Shift-Control-Home extends the selection to the
origin.
</DD>

<DT>[9] </DT></DT>
<DD>   Shift-Control-End extends the selection to the end.
</DD>

<DT>[10] </DT></DT>
<DD>The left, right, up and down arrows move the active
cell.
</DD>
</DL>
<P>
[11] Shift-&lt;arrow&gt; extends the selection in that direction.
<P>
[12] Control-leftarrow and Control-rightarrow move the
insertion cursor within the cell.

<DL>

<DT>[13] </DT></DT>
<DD>Control-slash selects all the cells.
</DD>
</DL>
<P>
[14] Control-backslash clears selection from all the
cells.
<P>
[15] Backspace deletes the character before the insertion
cursor in the active cell.
<P>
[16] Delete deletes the character after the insertion
cursor in the active cell.
<P>
[17] Escape rereads the value of the active cell from
the specified data source, discarding any edits
that have may been performed on the cell.
<P>
[18] Control-a moves the insertion cursor to the beginning
of the active cell.
<P>
[19] Control-e moves the insertion cursor to the end of
the active cell.
<P>
[20] Control-minus and Control-equals decrease and
increase the width of the column with the active
cell in it.
<P>
[21] Moving the mouse while Button-3 (the right button
on Windows) is pressed while you are over a border
will cause interactive resizing of that row and/or
column to occur, based on the value of <B>-resizeborders</B>.
<P>
Some bindings may have slightly different behavior dependent
on the <B>-selectionmode</B> of the widget.
<P>
If the widget is disabled using the <B>-state</B> option, then
its view can still be adjusted and cells can still be
selected, but no insertion cursor will be displayed and no
cell modifications will take place.
<P>
The behavior of tables can be changed by defining new
bindings for individual widgets or by redefining the class
bindings. The default bindings are either compiled in or
read from a file expected to correspond to: &laquo;[lindex
$tcl_pkgPath 0]/Tktable&lt;version&gt;/tkTable.tcl".

<H2><A NAME="sect14" HREF="#toc14"><B>Performance</B> <B>Issues</B></A></H2>

<P>
The number of rows and columns or a table widget should
not significantly affect the speed of redraw. Recalculation
and redraw of table parameters and cells is
restricted as much as possible.
<P>
The display cell with the insert cursor is redrawn each
time the cursor blinks, which causes a steady stream of
graphics traffic. Set the <B>-insertofftime</B> option to 0
avoid this. The use of a <B>-command</B> with the table without
a cache can cause significant slow-down, as the command is
called once for each request of a cell value.

<H2><A NAME="sect15" HREF="#toc15"><B>Examples</B></A></H2>

<P>
Set the topleft title area to be one spanning cell. This
overestimates both row and column span by one, but the
command does all the constraining for us.
$table span [$table cget -roworigin],[$table cget -colorigin] [$table cget -titlerows],[$table cget -titlecols]
Force a table window refresh (useful for the slight chance
that a bug in the table is not causing proper refresh):
$table configure -padx [$table cget -padx]
