QSound Class Reference
[QtGui module]

Detailed Description

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 using the static play() function:

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

Alternatively, create a QSound object from the sound file first and then call the play() slot:

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

Once created a QSound object can be queried for its fileName() and total number of loops() (i.e. the number of times the sound will play). The number of repetitions can be altered using the setLoops() function. While playing the sound, the loopsRemaining() function returns the remaining number of repetitions. Use the isFinished() function to determine whether the sound has finished playing.

Sounds played using a QSound object may use more memory than the static play() function, but it may also play more immediately (depending on the underlying platform audio facilities). Use the static isAvailable() function to determine whether sound facilities exist on the platform. Which facilities that are actually used varies:

Note that QSound does not support resources. This might be fixed in a future Qt version.
