// Name: wxMenuButton
// Purpose: A button with a dropdown wxMenu

/*
wxMenuButton is a button that drops down an assigned wxMenu
Create the button with either a text or bitmap label.
Create a new wxMenu and call AssignMenu and thats it. When you press the
dropdown button the menu appears. When you press the label button the next
wxITEM_RADIO (ie wxMenuItem::GetKind) in the menu is selected round robin.
If there are no radio items then it really just acts like a menubar, though
this is probably not too useful. The events sent in this case are EVT_MENUs
either generated by the menu when you click on it or created when you click
on the label to select the next radio item.
