Hooking Event at NSWindow - cocoa

Question

I'm making popup tooltip in NSWindow, like following XCode tooltip
If user press a button, popup is shown. It is easy.
But after that, if user press any button in this window, popup should be hidden.
But if user press button, nswindow's mousedown: isn't be called. so nswindowcontroller can not receive that event.
How can nswindow can detect all event in window's region?

You can create a contextMenu for small window, that opens on your action.
*NOTE: in the image, that is a custom view, not a contextMenu.*
- (IBAction)button:(id)sender {
NSRect frame = [(NSButton *)sender frame];
NSPoint menuOrigin = [[(NSButton *)sender superview] convertPoint:NSMakePoint(frame.origin.x+80, frame.origin.y+frame.size.height-10)
toView:nil];
NSEvent *event = [NSEvent mouseEventWithType:NSLeftMouseDown
location:menuOrigin
modifierFlags:NSLeftMouseDownMask // 0x100
timestamp:0.0
windowNumber:[[(NSButton *)sender window] windowNumber]
context:[[(NSButton *)sender window] graphicsContext]
eventNumber:0
clickCount:1
pressure:1];
NSMenu *menu = [[NSMenu alloc] init];
[menu setAutoenablesItems:NO];
[menu insertItemWithTitle:#"Add Favorite"
action:#selector(addFavorite:)
keyEquivalent:#""
atIndex:0];
[menu insertItem:[NSMenuItem separatorItem] atIndex:1];
[menu insertItemWithTitle:#"Manage Favorite"
action:#selector(manageFavorite:)
keyEquivalent:#""
atIndex:2];
[NSMenu popUpContextMenu:menu withEvent:event forView:(NSButton *)sender];
}
-(IBAction)addFavorite:(id)sender{
NSLog(#"add");
}
-(IBAction)manageFavorite:(id)sender{
NSLog(#"mangage");
}
