Re: Keybindings

[Dong Luo <us917 yahoo com>]

Please check references for gtk and gdk. I just did that and came with a simple example showing the 
keyBindings. Please note that it's not tested as I currently don't have gtk installed on my machine.

static gboolean keyBindings( GtkWidget *widget,
                              GdkEvent  *event,
                              gpointer   data )
{
    GtkWidget *popup;

    if (event->type != GDK_KEY_PRESS) return FALSE;
    
    // here crtl-x will popup a new window
    if (((GdkEventKey)event->keyval == GDK_x) &&
        ((GdkEventKey)event->state & GDK_CONTROL_MASK)) {
        popup = gtk_window_new(GTK_WINDOW_POPUP);
        gtk_widget_show (window);
    }
    // more keyBindings can be checked
    
    return TRUE;
}

int main( int   argc,
          char *argv[] )
{
    GtkWidget *window;

    gtk_init (&argc, &argv);

    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

    g_signal_connect (window, "key_press_event", G_CALLBACK (keyBindings), NULL);

    gtk_widget_show (window);
    gtk_main();
    return 0;
}

Could you show me an example as I have figured out the key-press-event is the key here, but I can't seem to 
figure it out yet. Do I set up a signal_connect from the window or something?
