[Gtk-sharp-list] KeepAbove? is there a "always ontop"?

[Gert Burger]

Hi

Im busy writing a program which need atleast one window to be the
topmost always, atleast when the program is active and maximized.

Another requirement is that the parent window or main application window
must still be able to accept user input via mouse events etc(which are
meant for the parent window).

Therefore modals seem out of the question, is there another way?

Thank you
