       QSound - Access to the platform audio facilities


       #include <qsound.h>

       Inherits QObject.

   Public Members
       QSound ( const QString & filename, QObject * parent = 0, const char * name = 0 )
       ~QSound ()
       int loops () const
       int loopsRemaining () const
       void setLoops ( int l )
       QString fileName () const
       bool isFinished () const

   Public Slots
       void play ()
       void stop ()

   Static Public Members
       bool isAvailable ()
       void play ( const QString & filename )
       bool available ()


       The QSound class provides access to the platform audio facilities.

       Qt provides the most commonly required audio operation in GUI applications: asynchronously
       playing a sound file. This is most easily accomplished with a single call:


       A second API is provided in which a QSound object is created from a sound file and is
       played later:

               QSound bells("mysounds/bells.wav");

       Sounds played using the second model may use more memory but play more immediately than
       sounds played using the first model, depending on the underlying platform audio

       On Microsoft Windows the underlying multimedia system is used; only WAVE format sound
       files are supported.

       On X11 the Network Audio System is used if available, otherwise all operations work
       silently. NAS supports WAVE and AU files.

       On Macintosh, ironically, we use QT (QuickTime) for sound, this means all QuickTime
       formats are supported by Qt/Mac.

       On Qt/Embedded, a built-in mixing sound server is used, which accesses /dev/dsp directly.
       Only the WAVE format is supported.

       The availability of sound can be tested with QSound::isAvailable().

       See also Multimedia Classes.


QSound::QSound ( const QString & filename, QObject * parent = 0, const char * name = 0 )

       Constructs a QSound that can quickly play the sound in a file named filename.

       This may use more memory than the static play function.

       The parent and name arguments (default 0) are passed on to the QObject constructor.

QSound::~QSound ()

       Destroys the sound object. If the sound is not finished playing stop() is called on it.

       See also stop() and isFinished().

bool QSound::available () [static]

       Returns TRUE if sound support is available; otherwise returns FALSE.

QString QSound::fileName () const

       Returns the filename associated with the sound.

bool QSound::isAvailable () [static]

       Returns TRUE if sound facilities exist on the platform; otherwise returns FALSE. An
       application may choose either to notify the user if sound is crucial to the application or
       to operate silently without bothering the user.

       If no sound is available, all QSound operations work silently and quickly.

bool QSound::isFinished () const

       Returns TRUE if the sound has finished playing; otherwise returns FALSE.

       Warning: On Windows this function always returns TRUE for unlooped sounds.

int QSound::loops () const

       Returns the number of times the sound will play.

int QSound::loopsRemaining () const

       Returns the number of times the sound will loop. This value decreases each time the sound

void QSound::play ( const QString & filename ) [static]

       Plays the sound in a file called filename.

       Example: sound/sound.cpp.

void QSound::play () [slot]

       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Starts the sound playing. The function returns immediately. Depending on the platform
       audio facilities, other sounds may stop or may be mixed with the new sound.

       The sound can be played again at any time, possibly mixing or replacing previous plays of
       the sound.

void QSound::setLoops ( int l )

       Sets the sound to repeat l times when it is played. Passing the value -1 will cause the
       sound to loop indefinitely.

       See also loops().

void QSound::stop () [slot]

       Stops the sound playing.

       On Windows the current loop will finish if a sound is played in a loop.

       See also play().
