Here are two common problems.  First, if you get a BadWindow error showing a
0x0 window ID, you're probably calling XtWindow() on a widget that is not
realized.  See the previous subject.

Second, a BadMatch error often indicates that the depth of a window or a
pixmap is not correct.  You could be using a depth 1 pixmap when you should be
using a pixmap with the depth of the associated window.  Or, you could be
creating a new shell with a depth that does not match its visual type or
colormap.
