Here's a rather ugly hack I am using:
int temp;
XWindowAttributes attr;
Window win, wdummy1, *wdummy2;
win = fl_show_form_window( form );
XQueryTree( display, win, &wdummy1, &win, &wdummy2, &temp );
XQueryTree( display, win, &wdummy1, &win, &wdummy2, &temp );
XGetWindowAttributes( display, win, &attr );
Now attr.x and attr.y are the 'real' window coordinates, i.e. the ones
you should use (instead of form.x and form.y) to draw the form at the
same position again. Or use the differences to figure out the sizes of
the borders the window manager adds. If someone has a nicer solution I
would be happy to hear about it...
Regards, Jens
