+// 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.

+    //  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)
