How to shape a button

["Chris Wu" <Chris Wu Sanmina-SCI Com>]

Hi all,
       I would like to make a shaped button, but when I use the
gtk_widget_shape_combine_mask(button, mask, 0, 0).
      The follow item is my source code.
      It can be passed build all step and no exception to run , but still
can't shaped the button as the shape.
      According your suggestion, I write  a test code and send to you.
      I used the follow envionment for development.
      OS : RedHat Linux 9.0
      IDE: Anjuta 1.2.2
      GTK+: GTK 2.0
      Can you give me any suggestion, thanks !
