Re: motion notify event messages.

["Shane Miller" <SMiller1 stvgb org>]

Looking at the C source for the gtk widgets I've noticed that all the widgets that don't work correctly in 
Lazarus (x coord's relative to the parents form instead of itself) don't assign a motion_notify event in the 
class_init function.  Does this mean that the motion events are not really handled by a button and are really 
being sent from the form?

Is the form getting the motion-notify and passing it on to the button because the button has grabbed the 
pointer (left mouse button was clicked on the button)?

Make a small test case we can look at, we'll take a look.
Hard to speculate on what might be wrong without seeing code.
