Usage

The Gesture event is triggered only on a Tablet PC. On a Tablet PC, the InkEdit control recognizes the following gestures that represent keystrokes that are frequently used in edit controls. To ensure that the gestures are recognized, users should draw straight lines and sharp right angles without removing the stylus from the control. InkEdit controls on other computers behave as MultiLineEdit controls and cannot accept ink input from a mouse.

When you tap the stylus or click a mouse in an InkPicture control on a Tablet PC, the Gesture event is triggered. On other computers, a mouse click triggers the Stroke event. The CollectionMode property must be set to GestureOnly! for a double tap to be recognized. Only single-stroke gestures are recognized when CollectionMode is set to InkAndGesture!. If a gesture is not recognized, the value of the argument is 0.

Examples

This code in the Gesture event of an InkEdit control confirms to the user that the gesture was recognized: 

CHOOSE CASE gest
   CASE 0
      MessageBox("Gesture recognized",  &
         "You entered a space")
   CASE 1
      MessageBox("Gesture recognized",  &
         "You entered a backspace")
 
   CASE 2,4
      MessageBox("Gesture recognized",  &
         "You entered a tab")
   CASE 3,5
      MessageBox("Gesture recognized",  &
         "You entered a return")
END CHOOSE

return false
