[comp.sys.mac.misc] window that covers the menus?

laraa@kgw2.Xetron.COM (Lara Anderson) (03/27/91)

We need to put up a window that covers the whole screen, including
the menu bar.  Thsi will be used in a screen lock feature that must
hide all windows and menus.  What do we need to tweak to allow the
window to cover the menus?  Do we just set the MBarHeight to zero?
Do we need to modify the WMgrPorts visRgn or clipRgn?

Has anyone accomplished this?
