Context menu tooltips

["Evgeny Repekto" <repekto argosoft gmail com>]

Hi gtkmm users,

I'm first time posting here. I got a little problem on context menu item. I can not see a tooltip.
This is a part of code where I'm adding the menu item:

mRefActionGroup->add( Gtk::Action::create("ContextAdd",
Gtk::Stock::ADD, "Add", "Ctrl-P"), Gtk::AccelKey("<control>P"));

But I dont see something like this in the context menu:
"Add Icon" Add      Ctrl-P

Please give a me a hint whats wrong.
