// 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.

|
|
// 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
|
|
//
|
|
// Or, you can use the new (2.5.5+) event handler
|
|
// conversion macros - for instance the above could
|
|
// be done as
|
|
// wxCommandEventHandler(MyFrame::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
|
|
// the compiler doesn't really know it.
