The VolumeSlider widget provides a slider that is used to control the volume of an audio output device.
The slider also displays an icon indicating if the volume of the AudioOutput it is connected to is muted. The icon can be removed with setMuteVisible ().
It is possible to set the maximum value of the slider. By default, the minimum and maximum values of the slider are 0.0 (no sound) to 1.0 (the maximum volume the audio output can produce).
Here follows a code example:
Phonon.AudioOutput *audioOutput = new Phonon.AudioOutput(Phonon.MusicCategory);
Phonon.createPath(mediaObject, audioOutput);
Phonon.VolumeSlider *volumeSlider = new Phonon.VolumeSlider;
volumeSlider->setAudioOutput(audioOutput);
