Hi Kevin,

thank you for the feedback.

But your code snippet fails in my case, see below:

The above line results in:

Gdk-WARNING **: gdkdrawable-x11.c:970 drawable is not a pixmap or window
Segmentation fault

What could be the reason (x_window is a XtWindow(XmForm Widget), the same
result when i try a XtWindow(XmDrawingArea Widget)).

thanks

PS: I have posted a bug to bugzilla about the gtk_vbox_new():
