/* TrackingSlider This is an ubersimple subclass of NSSlider that exposes a tracking method on the cell which can be used to tell if the user is currently dragging the slider. This is used in the action of the slider (the slider action is sent continuously) so the position text label is updated, without actually seeking the song until the mouse is released. */ #import @interface TrackingSlider : NSSlider { NSMutableDictionary *bindingInfo; } - (BOOL)isTracking; @end
