Problem with WM or gtk+ in gdk_window_get_position()

["Oliver Schulze L." <oliver pla net py>]

Hi,
I have a problem with gdk_window_get_position() and the
cause could be the Window Maker window manager.

When using Window Maker as the windowmanager, and when
you call gdk_window_get_position() without moving
the window, you get the position of the window like if
it is at position(0, 0);

But, if you move the window, and then call gdk_window_get_position()
you get the right position.

Please note that that the gdk_window_get_position() return the
position of the window including the window manager decoration.

Run this litle code and compare the result. The code is
helloworld.c from gtk+1.2.6 without comments.

Regards
Oliver
