<description><p>This class is used for context menu events, sent to give the application a chance to show a context (popup) menu for a <seeerl marker="wxWindow"><c>wxWindow</c></seeerl>.
      </p><p>Note that if <seemfa marker="#getPosition/1"><c>getPosition/1</c></seemfa> returns wxDefaultPosition, this means that the event originated from a keyboard context button event, and you should compute a suitable position yourself, for example by calling <seemfa marker="wx_misc#getMousePosition/0"><c>wx_misc:getMousePosition/0</c></seemfa>.
      </p><p>Notice that the exact sequence of mouse events is different across the platforms. For example, under MSW the context menu event is generated after <c>EVT_RIGHT_UP</c> event and only if it was not handled but under GTK the context menu event is generated after <c>EVT_RIGHT_DOWN</c> event. This is correct in the sense that it ensures that the context menu is shown according to the current platform UI conventions and also means that you must not handle (or call <seemfa marker="wxEvent#skip/2"><c>wxEvent:skip/2</c></seemfa> in your handler if you do have one) neither right mouse down nor right mouse up event if you plan on handling <c>EVT_CONTEXT_MENU</c> event.
