    text
    copied!<p>I'm making a text editor using GTK3 in Vala. I have a <code>Gtk.MenuBar</code> in a <code>Gtk.Window</code> and I want to use accelerators to easily activate its <code>Gtk.MenuItems</code>. But I want the user to be able to change the key combinations, so I'm loading the accelerators specifications from a file using the method <code>Gtk.AccelMap.load("accels")</code>. However, after calling this method, the accelerators are not loaded: the menu items don't have <code>AccelLabels</code> and are not activated when I press the key combinations. Here are the two files I'm working on. The first file contains a small version of my application (to show what I'm trying to do) and the second one is the accels file from which I load the accels specifications, and they must be in the same directory.</p> <p>main.vala</p> <pre><code>// Compile me with: valac main.vala -o main --pkg gtk+-3.0 public class MyWindow: Gtk.Window { public MyWindow() { this.set_default_size(500, 500); var main_box = new Gtk.VBox(false, 0); this.add(main_box); var accel_group = new Gtk.AccelGroup(); this.add_accel_group(accel_group); // Load the accelerators from the file Gtk.AccelMap.load("accels"); // Create the action var quit_action = new Gtk.Action("file-quit", "Quit", "Quit the application", null); quit_action.activate.connect(()=&gt;{ Gtk.main_quit(); }); quit_action.set_accel_group(accel_group); quit_action.set_accel_path("&lt;MyWindow&gt;/File/Quit"); // Menubar var menubar = new Gtk.MenuBar(); main_box.pack_start(menubar, false, false, 0); var file = new Gtk.MenuItem.with_label("File"); menubar.add(file); var file_menu = new Gtk.Menu(); file.set_submenu(file_menu); var quit_mi = (Gtk.MenuItem)quit_action.create_menu_item(); file_menu.append(quit_mi); // Label var label = new Gtk.Label("My Window"); main_box.pack_start(label, true, true, 0); this.destroy.connect(Gtk.main_quit); } } int main(string[] args) { Gtk.init(ref args); var win = new MyWindow(); win.show_all(); Gtk.main(); return 0; } </code></pre> <p>"accels" file</p> <pre><code>; main GtkAccelMap rc-file -*- scheme -*- ; this file is an automated accelerator map dump ; ; (gtk_accel_path "&lt;MyWindow&gt;/File/Quit" "&lt;Control&gt;q") </code></pre> <p>So, why is this not working? What do I have to do before or after loading the accel file?</p> <p>PS: I don't want to use a <code>Gtk.UIManager</code>.</p>
