+// MediaPlayer
+//
+// This is a simple example of how to use all the funtionality of
+// the wxMediaCtrl class in wxWidgets.
+//
+// To use this sample, simply select Open File from the file menu,
+// select the file you want to play - and MediaPlayer will play the file in a
+// new notebook page, showing video if neccessary.
+//
+// You can select one of the menu options, or move the slider around
+// to manipulate what is playing.
+// %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+// %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+// Known bugs with wxMediaCtrl:
+//
+// 1) Certain backends can't play the same media file at the same time (MCI,
+// Cocoa NSMovieView-Quicktime).
+// 2) Positioning on Mac Carbon is messed up if put in a sub-control like a
+// Notebook (like this sample does) on OS versions < 10.2.

+ // of EVT_MENU the menu id and then the function to call.
+ //
+ // However, with wxEvtHandler::Connect you can avoid a

+ // the call the handler (more later).
+ //
+ // The downside is that due to the limitation that
+ // wxWidgets doesn't use templates in certain areas,
+ // You have to triple-cast the event function.
+ //
+ // There are five parameters to wxEvtHandler::Connect -
+ //
+ // The first is the id of the instance whose events
+ // you want to handle - i.e. a menu id for menus,
+ // a control id for controls (wxControl::GetId())
+ // and so on.
+ //
+ // The second is the event id. This is the same
+ // as the message maps (EVT_MENU) except prefixed
+ // with "wx" (wxEVT_MENU).
+ //
+ // The third is the function handler for the event -
+ // You need to cast it to the specific event handler
+ // type, then to a wxEventFunction, then to a
+ // wxObjectEventFunction - I.E.
+ // (wxObjectEventFunction)(wxEventFunction)
+ // (wxCommandEventFunction) &MyFrame::MyHandler
+ //
+ // The fourth is an optional userdata param -
+ // this is of historical relevance only and is
+ // there only for backwards compatibility.
+ //
+ // The fifth is the context in which to call the
+ // handler - by default (this param is optional)
+ // this. For example in your event handler
+ // if you were to call "this->MyFunc()"
+ // it would literally do this->MyFunc. However,
+ // if you were to pass myHandler as the fifth
