GestureNbPointer (Function)
In french: GesteNbPointeur
Returns the number of pointers in contact with the screen.
The returned value depends on how the function is used:
  • Used in an event linked to the movement of the pointer (click, move, pressed, released, etc.), returns the number of pointers (finger or stylus) currently in contact with the screen
  • Used in another event or process, returns the last known number of contact points.
Example
// -- Click code on an Image control
nbContactPoints is int
nbContactPoints = GestureNbPointer()
 
ToastDisplay("You are currently using " + nbContactPoints + " finger(s) on the screen")
Syntax
<Result> = GestureNbPointer()
<Result>: Integer
Number of pointers (fingers or styluses) that touch the screen.
