Turns on/off the 3rd mouse button capability. The value
may be specified in any of the forms acceptable to

Specifies a fixed size for the menu button label in any
of the forms acceptable to Tk_GetPixels. If the text
is too small to fit in the label, the text is clipped.
Note: Normally, when a new list is created, or new
items are added to an existing list, the menu button
label is resized automatically. Setting this option
overrides that functionality.
<P>
_________________________________________________________________
<P>
<H2><A NAME="sect7" HREF="#toc7"><B>DESCRIPTION</B></A></H2>
The <B>optionmenu</B> command creates an option menu widget with
options to manage it. An option menu displays a frame containing
a label and a button. A pop-up menu will allow for
the value of the button to change.
<P>
<H2><A NAME="sect8" HREF="#toc8"><B>METHODS</B></A></H2>
The <B>optionmenu</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:
<P>
<I>pathName</I> <I>option</I> ?<I>arg</I> <I>arg</I> ...?
<P>
<I>Option</I> and the <I>arg</I>s determine the exact behavior of the command.
<P>
Many of the widget commands for an optionmenu take as one
argument an indicator of which entry of the option menu to
operate on. These indicators are called <I>index</I>es and may be
specified in any of the following forms:
<P>
<DL>
<DT><I>number</I> <DD> Specifies the entry numerically, where 0
corresponds to the top-most entry of the option
menu, 1 to the entry below it, and so on.
<P>
</DD>
</DL>
<DL>
<DT><B>end</B> <DD> Indicates the bottommost entry in the menu. If
there are no entries in the menu then zero is
returned.
<P>
</DD>
</DL>
<DL>
<DT><B>select</B> <DD> Returns the numerical index of the currently
selected option menu entry. If no entries exist
in the menu, then -1 is returned.
<P>
</DD>
</DL>
<DL>
<DT><I>pattern</I> <DD> If the index doesn't satisfy one of the above
forms then this form is used. <I>Pattern</I> is
pattern-matched against the label of each entry
in the option menu, in order from the top down,
until a matching entry is found. The rules of
<B>Tcl_StringMatch</B> are used.
<P>
</DD>
</DL>
The following widget commands are possible for optionmenu
widgets:
<P>
<H2><A NAME="sect9" HREF="#toc9"><B>WIDGET-SPECIFIC</B> <B>METHODS</B></A></H2>
<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>optionmenu</B> command.
<P>
<I>pathName</I> <B>configure</B> ?<I>option</I>? ?<I>value</I> <I>option</I> <I>value</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>pathName</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</I> - <I>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>optionmenu</B> command.
<P>
<I>pathName</I> <B>delete</B> <I>first</I> ?<I>last</I>?<BR>
Delete all of the option menu entries between <I>first</I> and
<I>last</I> inclusive. If <I>last</I> is omitted then it defaults to
<I>first</I>.
<P>
<I>pathName</I> <B>disable</B> <I>index</I><BR>
Disable the option menu entry specified by <I>index</I>. Disabling
a menu item will prevent the user from being able
to select this item from the menu. This only effects
the state of the item in the menu, in other words,
should the item be the currently selected item, the
programmer is responsible for determining this condition
and taking appropriate action.
<P>
<I>pathName</I> <B>enable</B> <I>index</I><BR>
Enable the option menu entry specified by <I>index</I>. Enabling
a menu item allows the user to select this item
from the menu.
<P>
<I>pathName</I> <B>get</B><BR> ?<I>first</I>? ?<I>last</I>?
If no arguments are specified, this operation returns the currently
selected option menu item. Otherwise, it returns the name of the
option at index <I>first</I>, or a range of options between <I>first</I>
and <I>last</I>.
<P>
<I>pathName</I> <B>index</B> <I>index</I><BR>
Returns the numerical index corresponding to <I>index</I>.
<P>
<I>pathName</I> <B>insert</B> <I>index</I> <I>string</I> ?<I>string</I>?<BR>
Insert an item, or list of items, into the menu at
location <I>index</I>.
<P>
<I>pathName</I> <B>select</B> <I>index</I><BR>
Select an item from the option menu to be displayed as
the currently selected item.
<P>
<I>pathName</I> <B>sort</B> <I>mode</I><BR>
Sort the current menu in either <B>ascending</B>, or <B>descending</B>
order. The values <B>increasing</B>, or <B>decreasing</B> are
also accepted.
<P>

entry for details on the popupMenu component item.
