    I have been experimenting with Codesys MultiTouch Example

    By default, in the example, HandleSpreadPinchGesture is set to TRUE, but I have not been able to get the event called.
    What configuration and conditions are required to have HandleSpreadPinchGesture event called?

    Thanks!

    Note: using Codesys 3.5SP9P8, running a webVisu on a Windows Laptop with Touchscreen.
    Frame scrolling, flick detection, multiple IEC touch detection, touch of multiple visu elements at the same time are all working fine in the multi touch example.

    Hello sir,

    do you mind telling me what browser and version you are currently using for the webvisu?

    Best regards,

    Yes of course!

    I have tried it on :
    - Chrome Version 70.0.3538.110
    - IE Version 11.407.17134.0

    Hello sir,

    do you know if this issue still exists in SP13 Patch 2?

    Or are you limited to SP9 Patch 8?

    Best regards,
    Marcel

    Hello sir,

    after talking to the lead developer he mentioned that the spread-pinch feature was never released and therefore is not working.

    Best regards,
    Marcel

    Ok.
    Thank you for the follow-up.

    Can we conclude that the multiTouch is limited to the following (please correct if there are other features that are not mentionned here):

    • HandlePanGesture is called after moving the picture inside the frame (on finger released). ("Scrolling" page of the example)
    • HandleTouchEvent is called as soon as at least 1 finger touches the screen, can track up to 5 fingers at the same time. ("Flick detection" page of the example)
    • HandleFlickgesture is called if a swipe event occurs (on finger released). ("Flick detection" page of the example)
    • Simultaneous interaction with multiple Visu Elements is available out of the box when enabling MultiTouch. ("Multiple Inputs" and "Tow-Hand inputs" pages of the example)

    Thank you!
