GestureCurrentPointer (Function) In french: GestePointeurEncours Returns the pointer index (finger or stylus) that triggered the call of a specific multi-touch event in an Image control. This index can be used by GesturePosX and/or GesturePosY to get the vertical and/or horizontal position of the corresponding pointer.
PositionX is int
PositionX = GesturePosX(GestureCurrentPointer())
Syntax
<Result> = GestureCurrentPointer()
<Result>: Integer Pointer index (finger or stylus) that triggered the call of a "Pressed" or "Released" event associated with an Image control. The first pointer that touches the screen corresponds to index 1.Note: In the simulator or Android emulator, this number is always equal to 1. Remarks Limitations - Use condition:
- This function must be used in the events of an Image control that has enabled event calling for each pointer: option "Recall processes for each pointer (multiple pointers)" in the "Detail" tab of the control description.
- This function must be called in one of the following field events: "Press", "Release", "Finger scroll", "Horizontal and vertical scan" or "Finger zoom". Otherwise, the function will always return 1.
   Up to 2 pointers can be supported.
Miscellaneous - To find out the horizontal position (X) of a pointer, use GesturePosX.
- To find out the vertical position (Y) of a pointer, use GesturePosY.
- To find out the number of pointers in contact with the screen, use GestureNbPointer.
