After studying the code generated by Stetic, I found a (round about)
way to do it.
Creating the action group is pretty straight forward:
Gtk.ActionGroup actionGroup = new Gtk.ActionGroup("Demo");
Gtk.ActionEntry fileAction = new Gtk.ActionEntry("file", null, "File",
null, null, null);
Gtk.ActionEntry newAction = new Gtk.ActionEntry("new", Gtk.Stock.New,
"New", "<Ctrl>n", "Create a new file.", OnNewFile);
Gtk.ActionEntry openAction = new Gtk.ActionEntry("open",
Gtk.Stock.Open, "Open", "<Ctrl>o", "Open a file.", OnOpenFile);
actionGroup.Add(new Gtk.ActionEntry[]{fileAction, newAction, openAction});
When I do this, then try to get a menu item with
actionGroup.GetMenuItem(), I get the following runtime assertion
failure:
Gtk-CRITICAL **: gtk_accel_label_set_accel_closure: assertion
`gtk_accel_group_from_accel_closure (accel_closure) != NULL' failed
The menu item works, but again the accelerator doesn't. In order to
get the accelerator working and displayed properly, I need to create a
UiManager and populate it with a string:
Gtk.UIManager uiManager = new Gtk.UIManager();
uiManager.InsertActionGroup(actionGroup, 0);
AddAccelGroup(uiManager.AccelGroup);
uiManager.AddUiFromString("<ui><menubar name='menubar'><menu
action='file'><menuitem action='new'/><menuitem
action='open'/></menu></menubar></ui>");
Then I can get the fully functional menu bar with
uiManager.GetWidget("/menubar").
This seems to be a working solution, although creating the ui string
is hackish and undesirable. I understand that I could define the ui in
a file, but that doesn't suite my particular application as the ui is
already defined in a platform neutral xml file that I'm parsing
independently.
