Hi Aaron, You should take a look at the NSCell docs<http://developer.apple.com/mac/library/documentation/Cocoa/Reference/ApplicationKit/Classes/NSCell_Class/Reference/NSCell.html#//apple_ref/occ/instm/NSCell/trackMouse:inRect:ofView:untilMouseUp:> .
-Ken trackMouse:inRect:ofView:untilMouseUp: Discussion This method is *generally not overridden* because the default implementation invokes other NSCell methods that can be overridden to handle specific events in a dragging session. This method’s return value depends on the * untilMouseUp* flag. If *untilMouseUp* is set to YES, this method returns YES if the mouse button goes up while the cursor is anywhere; NO, otherwise. If * untilMouseUp* is set to NO, this method returns YES if the mouse button goes up while the cursor is within *cellFrame*; NO, otherwise. This method first invokes *startTrackingAt:inView:*<http://developer.apple.com/mac/library/documentation/Cocoa/Reference/ApplicationKit/Classes/NSCell_Class/Reference/NSCell.html#//apple_ref/occ/instm/NSCell/startTrackingAt:inView:>. If that method returns YES, then as mouse-dragged events are intercepted, * continueTracking:at:inView:*<http://developer.apple.com/mac/library/documentation/Cocoa/Reference/ApplicationKit/Classes/NSCell_Class/Reference/NSCell.html#//apple_ref/occ/instm/NSCell/continueTracking:at:inView:> is invoked until either the method returns NO or the mouse is released. Finally, *stopTracking:at:inView:mouseIsUp:*<http://developer.apple.com/mac/library/documentation/Cocoa/Reference/ApplicationKit/Classes/NSCell_Class/Reference/NSCell.html#//apple_ref/occ/instm/NSCell/stopTracking:at:inView:mouseIsUp:> is invoked if the mouse is released. If *untilMouseUp* is YES, it’s invoked when the mouse button goes up while the cursor is anywhere. If *untilMouseUp * is NO, it’s invoked when the mouse button goes up while the cursor is within *cellFrame*. You usually override one or more of these methods to respond to specific mouse events.
