.SH DESCRIPTION
The tile widgets let you create textured backgrounds. The texture is
a Tk image which is tiled over the entire background of the widget.
The offset of the tile usually aligns with the toplevel window
so that all sub-tiles line up. However,
image names containing an exlamation "!" (ususally
as the last char) are tiled absolutely.
.SH INTRODUCTION
With the advent of Tk 4.0, images are now easy to create and use in
applications. Images add interest to applications and they convey
more information. But one area where Tk hasn't taken advantage of
images is using images as textures for widgets. Since tiling is a
standard feature of windowing systems, it's very easy to use images
as textures.
.PP
Note:
Wize now adds a -tile option to Tk widgets natively.
However, these are retained to provide the -shadow option.
.PP
Tiled widgets take the standard Tk 4.0 widgets and add tiling
configuration options to them. Textures are specified by the name
of the image you wish to be tiled across the background of the widget.
.SH EXAMPLE
To add tiling to a widget, you simply create an image using
Tk's \fBimage\fR command and use the image name as the value for
the \fB\-tile\fR configuration option of the widget.
.CS
image create photo my_texture -file tan_paper.gif
blt::tile::frame .f -tile my_texture
.CE
The image \fBmy_texture\fR is added to the frame.
If \fBmy_texture\fR is updated, so will the widget background.
.CS
image create photo my_texture -file rain.gif
.CE
The tile widget commands reside in the "blt::tile" namespace, so
as not to collide with the normal Tk widgets.
An easy way to add tiling to existing programs is to import
the tile widget commands into the global namespace.
.CS
image create photo my_texture -file tan_paper.gif
namespace import -force blt::tile::*
frame .f -tile my_texture
.CE
To use one image for all texturing, you can use the "Tile" option
class name to specify the same image for all tile widgets.
.CS
image create photo my_texture -file tan_paper.gif
option add *Tile my_texture
.CE
.SH OPTIONS
The following configurations options are added to the widgets. If
a \fB\-tile\fB or \fB\-activetile\fR option is specified, it overrides
the background color of the widget.
.TP
\fB\-activetile \fIimage\fR
Specifies a textured background to display when the widget is active.
This option is available for the \fBtilebutton\fR,
\fBtilecheckbutton\fR, \fBtileradiobutton\fR, and \fBtilescrollbar\fR
widgets. \fIImage\fR is the name an image created using Tk's
\fBimage\fR command. The background of the widget is tiled with
\fIimage\fR. If \fIimage\fR is \fB""\fR, then the active background
color is displayed. The default is \fB""\fR.
.TP
\fB\-tile \fIimage\fR
Specifies a textured background to display for the widget.
\fIImage\fR is the name an image created using Tk's \fBimage\fR
command. The background of the widget is tiled with \fIimage\fR. If
\fIimage\fR is \fB""\fR, then the normal background color is
displayed. The default is \fB""\fR.
.TP
\fB\-shadow \fIshadow\fR
Set shadow for text.
.TP
\fB\-rotate \fIdegrees\fR
Support for rotating text in degrees, eg. 90, 180.
.TP
\fB\-checksize \fInum\fR
Specify the size of check/radio button indicator.
.TP
\fB\-icons \fIimages\fR
Give a list of 0, or 2-9 images to use for the indicators.
The first three are for normal,selected,tristate.
The next three repeat but for the active state.
The next three repeat but for the disabled state.
.TP
\fB\-bdimage \fIimage\fR
.TP
\fB\-activebdimage \fIimage\fR
.TP
\fB\-disabledbdimage \fIimage\fR
A border image that resizes to fit the widget.
.TP
\fB\-bdflags \fIint\fR
Set to -1 to perform inner rather than outer mirror.
