<h2>Detailed Description</h2>
<p>The SeekSlider class provides a slider for seeking to positions in media streams.</p>
<p>The SeekSlider connects to a <a href="phonon-mediaobject.html">MediaObject</a>, and controls the seek position in the object's media stream.</p>
<p>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.</p>
<p>Here follows a typical example of SeekSlider usage:</p>
<pre> 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();</pre>
