Windows Vista will send a WM_TABLET_FLICK Message to the application in order to make that application notified for Pen Click. And full information about any pen flick will be given by the FLICK_DATA Structure and FLICK_POINT Structure. This will include the followings :

• The screen will be coordinating where the flick will gets started.

• Action for the pen flick requested by the user.

• Direction of the pen flick.

• The Current state of the modifier key like CTRL or SHIFT.

Most of the time, all the application will respond to the WM_TABLET_FLICK Message. But some application may not respond to this message then windows vista will send WM_APPCOMMAND, WM_VSCROLL, or WM_KEYDOWN, depending on which action is associated with the pen flick to make application notified for pen flicks. By sending these messages, Application will respond to the messages even if that application does not support to the pen flick.

As soon as the user assign a command in control panel, application must respond to it in consistent manner. Windows Vista will display the visual feedback regarding the assigned command when user performs any pen flicks. It does not depends on how application is responding to the current pen flick. Sometime application may respond to some other pen flick then the requested pen flick. This means that application do have ability to react to the flicks but in some other way. But it does not mean that application is NOT RESPONDING.

Here are the actions which pen flick can perform. There are total four types of actions.
1. Scroll up or down.
2. Back or Undo.
3. Any keystroke or keystroke combination.
4. Activating a modifier key such as SHIFT.
