</pre><H2>DESCRIPTION</H2>
<P>
The <B>extbutton</B> extends the behavior of the atomic Tk button by
allowing text and an image or bitmap to coexist. The user may use
the -image or -bitmap options to specify an image as well as the
-imagepos option to specify image position relative to the text.
Note that the extbutton is not intended to be used without an
image/bitmap. There will be an emtpy space next to the text if
no image/bitmap is specified.
</pre><H2>METHODS</H2>
<P>
The <B>extbutton</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>
</pre><H2>INHERITED METHODS</H2>
Each of the following methods are inherited from itk::Archetype. See that
man page for details.
<pre>
<I>pathName <B>cget</B>
pathName <B>component</B>
pathName <B>config</B>
pathName <B>configure</B></I>
</pre>
</pre><H2>WIDGET-SPECIFIC METHODS</H2>
<DL>
<DT> <I><B>pathName invoke
</I></B>
<DD> Evaluates the command fragment associated with the -command option.
</DL>
<DL>
<DT> <I><B>pathName flash
</I></B>
<DD> Simulates the Tk button's flash command.
