QSound Class Reference

Member Function Documentation

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

Constructs a QSound object from the file specified by the given filename and with the given parent.

This may use more memory than the static play() function, but it may also play more immediately (depending on the underlying platform audio facilities).

See also play().

QSound::~QSound ()

Destroys this sound object. If the sound is not finished playing, the stop() function is called before the sound object is destructed.

See also stop() and isFinished().

QString QSound::fileName () const

Returns the filename associated with this QSound object.

See also QSound().

bool QSound::isAvailable () [static]

Returns true if sound facilities exist on the platform; otherwise returns false.

If no sound is available, all QSound operations work silently and quickly. An application may choose either to notify the user if sound is crucial to the application or to operate silently without bothering the user.

Note: On Windows this always returns true because some sound card drivers do not implement a way to find out whether it is available or not.

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.

See also loopsRemaining() and setLoops().

int QSound::loopsRemaining () const

Returns the remaining number of times the sound will loop (this value decreases each time the sound is played).

See also loops() and isFinished().

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

Plays the sound stored in the file specified by the given filename.

See also stop(), loopsRemaining(), and isFinished().

void QSound::play () [slot]

This is an overloaded function.

Starts playing the sound specified by this QSound object.

The function returns immediately. Depending on the platform audio facilities, other sounds may stop or be mixed with the new sound. The sound can be played again at any time, possibly mixing or replacing previous plays of the sound.

See also fileName().

void QSound::setLoops ( int number )

Sets the sound to repeat the given number of times when it is played.

Note that passing the value -1 will cause the sound to loop indefinitely.

See also loops().

void QSound::stop () [slot]

Stops the sound playing.

Note that on Windows the current loop will finish if a sound is played in a loop.

See also play().
