Don't delay the action/target part, write a wrapper function and delay that:
- (void)mouseUp:(NSEvent*)event
{
UNUSED_VAR(event);
NSMenuItem* item = [self enclosingMenuItem];
NSMenu* menu = [item menu];
// On mouseUp, we want to dismiss the menu being tracked:
[menu cancelTracking];
[self performSelector:@selector(delayedSendAction:) withObject:item
afterDelay:0];
}
- (void)delayedSendAction: (NSMenuItem *)item
{
// Then send the action to the target:
SEL act = [item action];
id targ = [item target];
if(act != nil && targ != nil)
// [NSApp sendAction:act to:targ from:item];
// Temporarily sending the About menu item so it'll fire the About box:
[NSApp sendAction:act to:targ from:[menu itemAtIndex:0]];
// Copied from MenuItemView sample project. I don't think this is necessary:
// [self setNeedsDisplay:YES];
}
