  • Button not react in multi layer configuration

    Hello, I use a stm32f7 cpu in multi layer configuration.
    When I create a button in first layer (background layer 0), it 's work fine but when I create button in foreground layer, button don't react and no message is send to callback window function. I have just a touch message send to background layer callback function. It seem touch message work only with with layer 0 (background or default layer).


    Thank.

  • Hi Jens,

    please make sure that you set the correct layer when writing touch coordinates into the PID buffer.

    Like this:

    C Source Code

    1. StatePID.Layer = LayerIndex;
    2. StatePID.Pressed = 1;
    3. StatePID.x = GetXFromTouch();
    4. StatePID.y = GetYFromTouch();
    5. GUI_PID_StoreState(&StatePID);


    The same has to be done if using the multi touch interface.

    Regards,
    Sven
