I suspect this may depend on who their parent is, and here's why.

According to Asente and Swick there are two ways you can play the resize
game.  In one the child requests a resize, the parent decides it's okay,
returns Yes, and the child calls it's resize method.  In the second the
parent decides it's okay, reconfigures the widget, returns Done and the
child doesn't have to do anything, since the resize method is called by the
reconfigure.  The catch here, and the reason it's important, is that the
child never sees "Done", it always sees "Yes" in either case - so it needs
to know which policy the widget-set is using.

I could be wrong, but I think that Motif is not using either of these
models consistantly - which could cause the problem you see.  (Alternatively
you might just have turned resizeWidth off in it or its parent.)

Would anyone care to comment on which policy Motif uses?

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
