Instance Property


The number of mouse clicks associated with a mouse-down or mouse-up event.


@property(readonly) NSInteger clickCount;


Raises an NSInternalInconsistencyException if accessed on a non-mouse event.

This property is set to 0 for a mouse-up event if a time threshold has passed since the corresponding mouse-down event. This is because if this time threshold passes before the mouse button is released, it is no longer considered a mouse click, but a mouse-down event followed by a mouse-up event.

The return value of this method is meaningless for events other than mouse-down or mouse-up events.
