The normal way people do this is either to set a property (XChangeProperty) or a selection (XSetSelectionOwner) on the window. You could study something like the EWMH specification http://standards.freedesktop.org/wm-spec/ or the Xembed specification http://standards.freedesktop.org/xembed-spec/ to see how this could work in practice. _______________________________________________ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
