wxSound Class Reference

#include <wx/sound.h>

Inheritance diagram for wxSound:

Detailed Description

This class represents a short sound (loaded from Windows WAV file), that can be stored in memory and played.

Currently this class is implemented on Windows and Unix (and uses either Open Sound System or Simple DirectMedia Layer).

Library:  wxAdvanced

Category:  Multimedia

bool	Play (unsigned flags=wxSOUND_ASYNC) const
	Plays the sound file.
static bool	Play (const wxString &filename, unsigned flags=wxSOUND_ASYNC)
	Plays the sound file.

Public Member Functions
	wxSound ()
	Default ctor.
	wxSound (const wxString &fileName, bool isResource=false)
	Constructs a wave object from a file or, under Windows, from a Windows resource.
	wxSound (size_t size, const void *data)
	Constructs a wave object from in-memory data.
virtual	~wxSound ()
	Destroys the wxSound object.

bool	Create (size_t size, const void *data)
	Constructs a wave object from in-memory data.
bool	IsOk () const
	Returns true if the object contains a successfully loaded file or resource, false otherwise.
Public Member Functions inherited from wxObject
	wxObject ()
	Default ctor; initializes to NULL the internal reference data.
	wxObject (const wxObject &other)
	Copy ctor.
virtual	~wxObject ()
	Destructor.
virtual wxClassInfo *	GetClassInfo () const
	This virtual function is redefined for every class that requires run-time type information, when using the wxDECLARE_CLASS macro (or similar).
wxObjectRefData *	GetRefData () const
	Returns the wxObject::m_refData pointer, i.e. the data referenced by this object.
bool	IsKindOf (const wxClassInfo *info) const
	Determines whether this class is a subclass of (or the same class as) the given class.
bool	IsSameAs (const wxObject &obj) const
	Returns true if this object has the same data pointer as obj.
void	Ref (const wxObject &clone)
	Makes this object refer to the data in clone.
void	SetRefData (wxObjectRefData *data)
	Sets the wxObject::m_refData pointer.
void	UnRef ()
	Decrements the reference count in the associated data, and if it is zero, deletes the data.
void	UnShare ()
	This is the same of AllocExclusive() but this method is public.
void	operator delete (void *buf)
	The delete operator is defined for debugging versions of the library only, when the identifier WXDEBUG is defined.
void *	operator new (size_t size, const wxString &filename=NULL, int lineNum=0)
	The new operator is defined for debugging versions of the library only, when the identifier WXDEBUG is defined.

Static Public Member Functions
static bool	IsPlaying ()
	Returns true if a sound is played at the moment.
static void	Stop ()
	If a sound is played, this function stops it.

Additional Inherited Members
Protected Member Functions inherited from wxObject
void	AllocExclusive ()
	Ensure that this object's data is not shared with any other object.
virtual wxObjectRefData *	CreateRefData () const
	Creates a new instance of the wxObjectRefData-derived class specific to this object and returns it.
virtual wxObjectRefData *	CloneRefData (const wxObjectRefData *data) const
	Creates a new instance of the wxObjectRefData-derived class specific to this object and initializes it copying data.
Protected Attributes inherited from wxObject
wxObjectRefData *	m_refData
	Pointer to an object which is the object's reference-counted data.

Constructor & Destructor Documentation

wxSound::wxSound

(

)

Default ctor.

wxSound::wxSound	(	const wxString &	fileName,
		bool	isResource = false
	)

Constructs a wave object from a file or, under Windows, from a Windows resource.

Call IsOk() to determine whether this succeeded.

Parameters

fileName	The filename or Windows resource.
isResource	true if fileName is a resource, false if it is a filename.

wxSound::wxSound	(	size_t	size,
		const void *	data
	)

Constructs a wave object from in-memory data.

Parameters

size	Size of the buffer pointer to by data.
data	The buffer containing the sound data in WAV format.

virtual wxSound::~wxSound ( )

virtual

Destroys the wxSound object.

Member Function Documentation

bool wxSound::Create	(	const wxString &	fileName,
		bool	isResource = false
	)

Constructs a wave object from a file or resource.

Parameters

fileName	The filename or Windows resource.
isResource	true if fileName is a resource, false if it is a filename.

Returns

true if the call was successful, false otherwise.

bool wxSound::Create	(	size_t	size,
		const void *	data
	)

Constructs a wave object from in-memory data.

Parameters

size	Size of the buffer pointer to by data.
data	The buffer containing the sound data in WAV format.

bool wxSound::IsOk

(

)

const

Returns true if the object contains a successfully loaded file or resource, false otherwise.

static bool wxSound::IsPlaying ( )

static

Returns true if a sound is played at the moment.

This method is currently not available under Windows and may not be always implemented in Unix ports depending on the compilation options used (in this case it just always returns false).

Availability:  only available for the wxGTK, wxOSX ports.

bool wxSound::Play

(

unsigned

flags = wxSOUND_ASYNC

)

const

Plays the sound file.

If another sound is playing, it will be interrupted.

Returns true on success, false otherwise. Note that in general it is possible to delete the object which is being asynchronously played any time after calling this function and the sound would continue playing, however this currently doesn't work under Windows for sound objects loaded from memory data.

The possible values for flags are:

• wxSOUND_SYNC: Play will block and wait until the sound is replayed.
• wxSOUND_ASYNC: Sound is played asynchronously, Play returns immediately.
• wxSOUND_ASYNC|wxSOUND_LOOP: Sound is played asynchronously and loops until another sound is played, Stop() is called or the program terminates.

The static form is shorthand for this code:

wxSound(filename).Play(flags);

static bool wxSound::Play ( const wxString &  filename, unsigned  flags = wxSOUND_ASYNC  )

static

Plays the sound file.

If another sound is playing, it will be interrupted.

Returns true on success, false otherwise. Note that in general it is possible to delete the object which is being asynchronously played any time after calling this function and the sound would continue playing, however this currently doesn't work under Windows for sound objects loaded from memory data.

The possible values for flags are:

• wxSOUND_SYNC: Play will block and wait until the sound is replayed.
• wxSOUND_ASYNC: Sound is played asynchronously, Play returns immediately.
• wxSOUND_ASYNC|wxSOUND_LOOP: Sound is played asynchronously and loops until another sound is played, Stop() is called or the program terminates.

The static form is shorthand for this code:

wxSound(filename).Play(flags);

static void wxSound::Stop ( )

static

If a sound is played, this function stops it.
