@plalq Qt Multimedia should sort you out.

@plalq

QSound::play

to the end of the function

You cant control that. play will start its own loop and return immediately to the function where it was called. So if your music file is 3mins long, the music will still play, even if the function is not executed at that moment.

You could use QSoundEffect and mute or stop the music when you reached the end of your function.

@Pl45m4
QMultimediaPlayer::start() at the start of the method and QMultimediaPlayer::stop() at the end, thank you.

Mentioned by you QSound also has stop() method.

@artwaw

But none of them ensures that the sound file reached its end, when you call stop at the end of your function where play was called :)

@plalq has to either check with isFinished() or deal with it

@Pl45m4 well, yes. Possibly I misread the title... Signal/slot relation being a backbone of Qt - I thought it's quite obvious.

Thank you both for your replies, I didn't express myself clearly, my mistake. I want to open a new thread for playing music, and when the music is finished, I can close the thread. The only way I can think of is to use QTimer to set a timer that counts down to the same amount of time as the music, and then listen to the timeout slot function to exit the thread. Is there a class that has a finished signal when the music finishes playing to do this?@artwaw @Pl45m4

The playing part is asynchronous. There's no need to open a thread.

@Bonnie ohhhh! thx, i found QSoundEffect::playingChanged is what i need , but it is not right now.

This is also what I was looking for for my device. Music playback is currently a trend of users of smart devices.
