Mouse events are delivered to a morph whose containsPoint: method returns 
true. By default, a morph returns true if cursor position is within its 
bounds. If you are dealing with special situations, create a class and 
override this method to handle the special conditions.

Also see containsPoint:event:  and dispatchMouseDown:with: methods.

You could also have morphs delegate selected events to other morphs. See 
on:send:to: for details.
