+// 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,
+// showing video if neccessary.
+//
+// You can select one of the menu options, or move the slider around
+// to manipulate what is playing.

-    //  Create a timer to update our status bar
+    //  Connect events.
+    //
+    //  There are two ways in wxWidgets to use events -
+    //  Message Maps and Connections.
+    //
+    //  Message Maps are implemented by putting
+    //  DECLARE_MESSAGE_MAP in your wxEvtHandler-derived
+    //  class you want to use for events, such as MyFrame.
+    //
+    //  Then after your class declaration you put
+    //  BEGIN_EVENT_TABLE(MyFrame, wxFrame)
+    //  EVT_XXX(XXX)...
+    //  END_EVENT_TABLE()
+    //
+    //  Where MyFrame 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) &MyFrame::MyHandler
+    //
+    //  The fourth is an optional userdata param -
+    //  this is of historical relevance only and is
+    //  there only for backwards compatability.
+    //
+    //  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
