WM_Gestures gives you a great variety of standard gestures. The message WParam gives you the gesture id (GID_...), whileLParam is a handle used to callGetGestureInfo(Msg.LParam, gestureInfo)to get gesture detail. It's important to free this handle by calling DefWindowProc() orCloseGestureInfoHandle(Msg.LParam). If you don't handle the message then make sure you callDefWindowProc() so Windows can process the message........

Adding touch messages to a Delphi form is fairly trivial. Note for WM_Gesture and WM_Touch we get a handle via Msg.LParam. It's important that once you have finished with these handles you must closed them to avoid memory leaks. Either call DefWindowProc() or if you handle the message, you can explicitly close the handle by callingCloseGestureInfoHandle(LParam)for WM_Gesture, orCloseTouchInputHandle(LParam)for WM_Touch........
