    • Problems with QR Code [Solved]

      Hello everybody,

      I have a problem with drawing QR Codes.
      I orientated myself on your example "GUI_QRCode.c" but it does not draw anything. I tried to draw a rectangle/polygon instead but this also fails. What could it be?
      Graphs, tables and so on are working fine.

      Thank you very much

      C Source Code

      1. static void _cbScreen5(WM_MESSAGE * pMsg)
      2. {
      3. WM_HWIN hItem;
