The problem with this is that it depends on the windowmanager if it obeys the mentioned Tk::WM functions. The Windowmanager can do what it wants with it.

For example: those functions won't work on Win32 and I believe that Enlightenment also ignores those settings.

I think what you would want is to run in Fullscreen mode. This is (as far as I know) not supported by any Tk function, but wxPerl supports this for Win32 platforms. Again, the function will be ignored on Un*x flavours.
