Disabling System Gestures By default a window application receives all system gesture events. You may need to disable some system gesture events by responding to WM_TABLET_QUERYSYSTEMGESTURESTATUS message in your window procedure. Refer to the article, "WM_TABLET_QUERYSYSTEMGESTURESTATUS Message Message," on MSDN for more details: Additional advanced touch input manipulation is available on MSDN at http://msdn.microsoft.com/. Touch Support in Windows 7® Windows 7 provides a richer support for the development of touch applications. Support includes:  The default behavior for many gestures that touch-unaware applications automatically receive  Gesture messages (WM_GESTURE) to get gestures performed by users  Touch input messages (WM_TOUCH) to get information about specific contact points  Manipulation APIs (using manipulation processor and inertia processor) on top of touch input messages to get actions performed by users as well as how actions can be interpreted An application can receive either gesture messages or touch input messages but not both at the same time. By default, Windows sends WM_GESTURE notifications to an application. If the application does not handle these events, they are bubbled up and Windows will send back equivalent legacy messages like mouse left button click, mouse left double click, mouse right button up, mouse right button down, etc. Consequently, that is why touch-unaware applications can still get good touch support. Not all gestures have equivalent legacy messages. To provide a better touch user experience, you may need to handle gesture messages that have no legacy 13
