Hello Mr. Ammon,
It does help. Thank you!
To test this out, I simply subclassed NSButton and only replaced the mouseDown:
method with the following:
- (void) mouseDown:(NSEvent *)theEvent
{
NSPopUpButtonCell *cell = [[NSPopUpButtonCell alloc] initTextCell:@""
pullsDown:NO];
NSMenu *tempMenu = [[[NSMenu alloc] init] autorelease];
[tempMenu addItemWithTitle:@"first item" action:NULL keyEquivalent:@""];
[tempMenu addItemWithTitle:@"second item" action:NULL keyEquivalent:@""];
[tempMenu addItemWithTitle:@"third item" action:NULL keyEquivalent:@""];
NSRect viewBounds = [self bounds];
[cell setMenu:tempMenu];
[cell performClickWithFrame:viewBounds inView:self];
[cell release];
}
Is there any reason why I shouldn't pass in the view bounds to
performClickWithFrame:inView:?
Is it possible to have more control over where the menu appears relative to the
view? For example, I would like to have the menu appear to the right of the
view so the view is not obscured by the menu. I tried:
[cell performClickWithFrame:NSMakeRect(NSMaxX(viewBounds), 0, 1, 1)
inView:self];
which comes close...the menu is shifted to the right, but still obscures part
of the view. I haven't tried playing around with popUpMenuPositioningItem:
atLocation: inView: from NSMenu in 10.6 to see if it will work any differently,
but only because I need to stay with the 10.5 SDK for now.
Oh, as Mr. Sluder suggested, I have filed a documentation bug - rdar://7546017
Thanks again.
