init_check

Initializes GTK.

This function does the same work as [func@Gtk.init] with only a single change: It does not terminate the program if the windowing system can’t be initialized. Instead it returns false on failure.

This way the application can fall back to some other means of communication with the user - for example a curses or command line interface.

Returns:

true if the windowing system has been successfully initialized, false otherwise
