  • Cannot make window transparent

    Hi,

    I wanted to implement a wait dialog that shows an hourglass animated gif above
    the current gui.
    Unfortunately I cannot manage to make the dialog window invisible (transparent).
    I already set the WM_CF_HASTRANS flag on the GUI_WIDGET_CREATE_INFO,
    I called WM_SetHasTrans() on the window, I tried to set the background color
    to invalid. Nothing works. There is always a rectangular shape in the background.
    What am I doing wrong?

    Thanks in advance,
    Stefan Sixt.
