Hi,
I have a custom view viewA contained within a scrollview. I wanted
to add a subview viewB in viewA so I do something this (self is viewA):
viewB = [[MyOverlayView alloc] initWithFrame:[self bounds]
view:self];
[self addSubview:viewB];
After I do the above, viewB is created and inserted into viewB
(completely overlaying it) but both viewA and viewB receive mouse
events? I overrode hitTest and all mouse events to make sure and it
is indeed the case. All events come to viewB first, then to viewA
which seems to contradict what I expect based on the docs.
However, if I change the code above to insert viewB not in viewA but
in the scroll view containing viewA like the following:
[[self superview] addSubview:viewB];
then everything seems to be working more logically, only the top view
viewB receives mouse events.
I assume this is correct behavior but I cannot figure out why?
So why do both viewA and viewB receive mouse events in the first case
above?
Cheers,
-- ivan
