    • Disable focus re-drawing on GUIBuilder generated BUTTON

      Hi to all,

      I'm using STemwin ( a free version of EMWinprecompiled for STM32 processor) in this release, GUIBuilder is delivered for free.

      My project consist of a resistive touch screen.
      I want to disable the focus feature of Buttons, because press on a button cause redraw of previously pressed button.

      How can I do this ?

      this is my GUIBuilder outpu:

      Thanks for your time.

      Regards

    • Hi,

      You can disable the focus ability of a widget with WIDGET_SetFocusable(). It makes sense to disable the focus in the WM_INIT_DIALOG case of your dialog callback:

      C Source Code

      1. for (i = 0; i < 5; i++) {
      2. hItem = WM_GetDialogItem(pMsg->hWin, ID_BUTTON_0 + i);
      3. WIDGET_SetFocusable(hItem, 0);
      4. }
      Best regards,
      Florian
