.SH DESCRIPTION
.PP
The \fBextbutton\fR 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.
.SH "METHODS"
.PP
The \fBiwidgets::extbutton\fR command creates a new Tcl command whose
name is \fIpathName\fR. This command may be used to invoke various
operations on the widget. It has the following general form:
.DS C
\fIpathName option \fR?\fIarg arg ...\fR?
.DE
.SH "INHERITED METHODS"
Each of the following methods are inherited from itk::Archetype. See that
man page for details.
.DS C
\fIpathName \fBcget\fR
\fIpathName \fBcomponent\fR
\fIpathName \fBconfig\fR
\fIpathName \fBconfigure\fR
.DE
.SH "WIDGET-SPECIFIC METHODS"
.TP
\fIpathName \fBinvoke\fR
Evaluates the command fragment associated with the -command option.
.TP
\fIpathName \fBflash\fR
Simulates the Tk button's flash command.
