Subclass of DrawingArea refuses focus

Submitted by fredk on Fri, 08/28/2009 - 18:45.

I have subclassed an XmDrawingArea.
My subclass draws some things directly, and has one child. I capture Button1Down and call XmProcessTraversal(me,XmTRAVERSE_CURRENT).

The traversal always fails. If my child is an XmLabel, input focus after the traversal call remains with the old widget that had focus; if my child is a button, the button becomes the new focus widget after the traversal call.

Why can't my widget get focus?

And the answer seems to be that a Manager or subclass thereof cannot accept focus if it has any focusable descendants.
