I think I found what is going on. The big Question is how can I solve
the problem.
More info : My view is placed is the right pane of a splitter. |n
the left pane, there is a tableView with the exact height as the weird
invalidated rectangle.
The invalidation in called by the default event loop by sending an
- (void)setNeedsDisplayInRect:(NSRect) aRect; with another view's
rectangle (only height ) !!!!
But why is it using the tableView's height (which is situated in a
different splitter pane?). What can be wrong here?
as usual, Cristian

Hello list,
I encountered a weird NSView behavior and maybe someone could help
me with this :
my view (descendant of NSQuickDrawView) needs to be repainted as a
result of a user action (button click).
for this : i am sending an setNeedsDisplay:YES and
setNeedsDisplayInRect:rect and (normally) drawRect is called.
The problem is that, from time to time, "someone else" is
"calling" my drawRect and my view is repainted as if an
setNeedsDisplayInRect (with always the same rect) was sent but I
certainly didn't.
How can an area can be marked as needed to be displayed withought
an explicit call and withought being overlapped by another window or
panel ?
I tried to overwrite needsDisplay, but drawRect is called even if
needsDisplay returns NO. How can this be possible ?
Can anybody advice ? Any hint or pointer ?
Best wishes, Cristian
