The way to get beginGestureWithEvent / endGestureWithEvent if the window is not in front

Question

Is there any way to get

- (void)beginGestureWithEvent:(NSEvent *)event

and

- (void)endGestureWithEvent:(NSEvent *)event

triggers a view even if the containing window is in the background? It seems that these calls are only delivered to windows if they are key.

Answer 1

In general, no. In Leopard and SnowLeopard gestures are designed to set only the foreground. As you have discovered, the window server does not even send gesture events to background applications.
