DESCRIPTION
       The extbutton 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.


METHODS
       The iwidgets::extbutton command creates a new Tcl command whose name is pathName.  This  command  may
       be used to invoke various operations on the widget.  It has the following general form:

              pathName option ?arg arg ...?



INHERITED METHODS
       Each of the following methods are inherited from itk::Archetype. See that man page for details.

              pathName cget
              pathName component
              pathName config
              pathName configure



WIDGET-SPECIFIC METHODS
       pathName invoke
              Evaluates the command fragment associated with the -command option.

       pathName flash
              Simulates the Tk button's flash command.



EXAMPLES
              package require Iwidgets 4.0
              iwidgets::extbutton .eb -text "Bitmap example" -bitmap info \
                -background bisque -activeforeground red -bitmapforeground blue \
                -defaultring 1 -command {puts "Bisque is beautiful"}
              pack .eb -expand 1

              iwidgets::extbutton .eb -text "Image example" -relief ridge -image \
                [image create photo -file $itk::library/../iwidgets/demos/images/clear.gif] \
                -font 9x15bold -background lightgreen -imagepos e \
                -activebackground lightyellow
