I grepped through the MWF code for transparency and stumbled upon
SetWindowTransparency in X11Hwnd.cs. But this seems to ignore the
Color key parameter [1] and makes the whole window (of the control)
transparent (I might be wrong?), which means that whatever I draw in
the foreground will be transparent as well. I "just" want a
transparent background.
[1]
private void SetWindowTransparency (IntPtr handle, double
transparency, Color key)
{
IntPtr x11_opacity;
opacity = (uint)(0xffffffff * transparency);
x11_opacity = (IntPtr)((int)opacity);
IntPtr w = WholeWindow;
if (reparented)
w = display.XGetParent (WholeWindow);
Xlib.XChangeProperty (display.Handle, w,
display.Atoms._NET_WM_WINDOW_OPACITY, display.Atoms.XA_CARDINAL, 32,
PropertyMode.Replace, ref
x11_opacity, 1);
}
