+// MediaPlayer
+//
+// This is a somewhat comprehensive 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
+// the current notebook page, showing video if necessary.
+//
+// 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).

+ // Message Maps are implemented by putting

+ // class you want to use for events, such as wxMediaPlayerFrame.
+ //
+ // Then after your class declaration you put
+ // BEGIN_EVENT_TABLE(wxMediaPlayerFrame, wxFrame)
+ // EVT_XXX(XXX)...
+ // END_EVENT_TABLE()
+ //
+ // Where wxMediaPlayerFrame is the class with the DECLARE_MESSAGE_MAP
+ // in it. EVT_XXX(XXX) are each of your handlers, such
+ // as EVT_MENU for menu events and the XXX inside
+ // is the parameters to the event macro - in the case
+ // of EVT_MENU the menu id and then the function to call.
+ //
+ // However, with wxEvtHandler::Connect you can avoid a
+ // global message map for your class and those annoying
+ // macros. You can also change the context in which
+ // 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) &wxMediaPlayerFrame::MyHandler
+ //
+ // Or, you can use the new (2.5.5+) event handler
+ // conversion macros - for instance the above could
+ // be done as
+ // wxCommandEventHandler(wxMediaPlayerFrame::MyHandler)
+ // pretty simple, eh?
+ //
+ // 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
+ // parameter, for instance, you would _really_
+ // be calling myHandler->MyFunc, even though
