This is most - easily accomplished using the static play() function: - - \snippet doc/src/snippets/code/src_gui_kernel_qsound.cpp 0 - - Alternatively, create a QSound object from the sound file first - and then call the play() slot: - - \snippet doc/src/snippets/code/src_gui_kernel_qsound.cpp 1 - - 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.
