|
|
<P>
|
|
The <B>pushbutton</B> command creates a push button with an
|
|
optional default ring used for default designation and traversal.
|
|
|
|
</pre><H2>METHODS</H2>
|
|
<P>
|
|
The <B>pushbutton</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:
|
|
<pre>
|
|
<I>pathName option </I>?<I>arg arg ...</I>?
|
|
</pre>
|
|
<I>Option</I> and the <I>arg</I>s
|
|
determine the exact behavior of the command. The following
|
|
commands are possible for pushbutton widgets:

<DL>
|
|
<DT> <I>pathName <B>cget</B> <I>option</I>
|
|
</I></B>
|
|
<DD> 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>pushbutton</B>
|
|
command.

<DL>
|
|
<DT> <I>pathName</I> <B>configure</B> ?<I>option</I>? ?<I>value option value ...</I>?
|
|
</I></B>
|
|
<DD> 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-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>pushbutton</B>
|
|
command.
