public void set_icon_from_file (string? file_name) throws Error
Sets the icon name hint for a window manager (like muffin) to make available when applications want to change their icons during runtime without having to resort to the internal low-res pixbufs that GdkWindow sets on the client side.
This also chains up and calls GtkWindow.set_icon_from_file for convenience and compatibility. Set to null to unset.
