Force the linker to include all the backends in the sample executable instead of discarding them because they are not used directly to allow testing all of them in the sample. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@65485 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

// 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).

|
|
// 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 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
|
|
// the compiler doesn't really know it.
