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.
