Re: newbie key binding question

Hi

Overload on_key_pressed() method and inside, handle the keypress event.
This is what I did in my project. Hope it helps.

ClassX is my class extending from Gtk::Window.

bool ClassX::on_key_pressed(GdkEventKey* event)
{
        try{
                if(!event)
                        return false;
        
                switch (event->keyval)
                {
                        case GDK_F1: {
                                action1();
                                break;
                        }
                        case GDK_F2: {
                                action2();
                                break;
                        }
                        case GDK_F3: {
                                action3();
                                break;
                        }
                        case GDK_F4: {
                                action4();
                                break;
                        }
                        default: {
                                break;
                        }
                }
        catch(exception &e) {
        }
        // Returning true would stop the event now
        return false;
}
