// Controls the Mac style menu bar on Unity.

// Unity has an Apple-like menu bar at the top of the screen that changes
// depending on the active window. In the GTK port, we had a hidden GtkMenuBar
// object in each GtkWindow which existed only to be scrapped by the
// libdbusmenu-gtk code. Since we don't have GtkWindows anymore, we need to
// interface directly with the lower level libdbusmenu-glib, which we
// opportunistically dlopen() since not everyone is running Ubuntu.
//
// This class is like the chrome's corresponding one, but it generates the menu
// from menu models instead, and it is also per-window specific.
