Use "context-*" menu as application/toolbar context menu

[racoon]

I try to solve one of the last puzzle for

http://www.lyx.org/trac/ticket/10283
and

http://www.lyx.org/trac/ticket/10428

What I need is to use a standard context menu from stdcontext.inc rather 
than the hard coded one as the application/toolbar context menu.

I tried to replace the toolBarPopup method in GuiView.cpp by

QMenu * toolBarPopup(GuiView * parent)
{
        std::string name = "context-toolbars";
        QMenu * menu = guiApp->menus().menu(toqstr(name), *parent);

        return menu;
}

and adding to stdcontext.inc a

#
# Toolbars context menu
#

        Menu "context-toolbars"
                Toolbars
        End

Unfortunately no context menu appears when I try to open the 
application/toolbar context menu.

The code does not create any errors

I tested whether the Toolbars menu is available as a context menu 
replacing another standard context menu by it. It works, so that is not 
the problem either.

Maybe my usage of parent as the GuiView is the problem

Any suggestions very welcome!
