Initialize Gtk+. This must be called before any other Gtk2 functions in a
GUI application; the Gtk2 module's import method allows you to pass
use statement to do this automatically. This function also scans
@ARGV for any options it knows, and will remove them automagically.
Note: this function will terminate your program if it is unable to initialize
the gui for any reason. If you want your program to fall back to some other
interface, you want to use
This is the non-fatal version of
Gtk2->init; instead of calling
if Gtk+ initialization fails,
Gtk2->init_check returns false. This
allows your application to fall back on some other means of communication with
the user - for example a curses or command-line interface.
Install a key "snooper" function which will get called on all key events before those events are delivered normally. These snoopers can be used to implement custom key event handling.
key_snooper_install returns an id that may be used with
key_snooper_remove (below). snooper is called as
stopbool = &snooper ($widget, $event, $func_data);
It should return true to stop event propagation, the same as
Gtk2::Widget event signal handlers. The
Gtk2::EVENT_PROPAGATE constants can be used for the return (see
This is the event handler that GTK+ registers with GDK. GTK+ exposes it to
allow filtering of events between GDK and GTK+; it is rare that you would
need this, except if you are using
