Mouse messages




Q. Are any messages passed while the mouse pointer is moving 
across the screen when it is not dragging any objects? 
 
A. Yes, mouse messages are constantly being passed as it 
moves across the screen. That's partially why mouse handlers 
return MRF_PROCESSED, so that the mouse message isn't passed 
to other objects. An object will receive MSG_META_PTR when 
the pointer moves inside its VisBounds, whether the button 
is down or not. That's why the TicTac sample application 
sets a "dragging" flag on the mouse press, so that the 
MSG_META_PTR method knows whether to process or ignore the 
event.
