i've solved this problem as follows: in my method that receives the
NSComboBoxWillDismissNotification notification:
- (void) comboBoxDidDismiss: (NSNotification*) aNotification {
NSEvent* curEvent = [NSApp currentEvent];
if ([curEvent type] == NSLeftMouseDown) {
do {
curEvent = [NSApp nextEventMatchingMask:
(NSLeftMouseDraggedMask | NSLeftMouseUpMask) untilDate: [NSDate
distantFuture] inMode: NSEventTrackingRunLoopMode dequeue: YES];
} while ([curEvent type] != NSLeftMouseUp);
}
}
personally, i consider it a bug that NSComboBox doesn't eat mouse
moved/up events generated after the dismissing mouse down. (i would
log a bug against this, but radar still isn't letting me in.)
however, my solution may be a bug waiting to happen. if apple in the
future should decide to eat mouse moved/up events, i hope that they
don't post the NSComboBoxWillDismissNotification on the mouse down,
otherwise my code would hang/loop until the next time the users pops
up the combo box again! can anyone suggest a way for my code to
prevent/anticipate this potential problem?
thanx,
ken

with some further checking, it turns out i do get the dismiss
notification when the combo box's popup dismisses via dragging the
window. but mouse click's are still dispatching to the wrong target.

notification of this. plus, from then on, mouse clicks are sent to
the wrong target! the only way i've been able to get mouse clicks
working properly again is to drag the window again!
has anyone seen similar (weird/absurd/errant) behavior? (i'd log a
bug except radar isn't giving me access today!)
also, if anyone has seen this before, can you suggest any work
around? since mouse clicks are being "dispatched" wrongly, i can't
think of anything offhand.
thanx for any sympathy, suggestions, etc.
