![]() 1. it's because when the user scrolls the ScrollView, LM_VSCROLL/LM_VSCROLL messages are sent to LCL in NSScrollView.scrollWheel() 2. when LCL processes these messages, it sets the position of NSScrollView by calling SetScrollInfo() 3. if NSScrollView is in the animation effect at this time, the Scroller will not be hidden after the animation 4. by adding functions, it is possible to distinguish whether the scrolling is initiated by the user or by LCL. if it is initiated by the user, there is no need to set the position of NSScrollView. |
