Info needed regarding gdk_pixbuf_get_depth

["Santhana Krishnan" <santhana krishnan wipro com>]

Hi,
    Is there any chance the depth of a drawable widget can be '0' ?  In the
following piece of code i am getting the depth value as zero for some
widgets (eg. buttons, label..).

   if (GDK_IS_DRAWABLE (widget))
   {
       depth = gdk_pixbuf_get_depth (widget);
    }

   Any idea what could be the problem?.

thanks in advance,
Santhana
