SeekSlider Class Reference |
|
|
The SeekSlider class provides a slider for seeking to positions in media streams.
The SeekSlider connects to a MediaObject, and controls the seek position in the object's media stream.
The slider will connect to the necessary signals to keep track of the sliders maximum, minimum, and current values. It will also disable itself for non-seekable streams, and update the media object when the current value of the slider changes.
Here follows a typical example of SeekSlider usage:
Phonon::MediaObject *moo = new Phonon::MediaObject;; Phonon::AudioOutput *device = new Phonon::AudioOutput; Phonon::createPath(moo, device); moo->setCurrentSource(QString("/home/gvatteka/Music/Lumme-Badloop.ogg")); Phonon::SeekSlider *slider = new Phonon::SeekSlider; slider->setMediaObject(moo); slider->show(); moo->play();
