## Detailed Description

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();

## Property Documentation

### iconSize : QSize

This property holds the icon size used for the mute button/icon.

The default size is defined by the GUI style.

Access functions:

QSize | iconSize () const
void | setIconSize ( const QSize & size )

### iconVisible : bool

This property holds whether the icon next to the slider is visible.

By default the icon is visible if the platform provides an icon; else it's hidden.

Access functions:

bool | isIconVisible () const
void | setIconVisible ( bool )

### orientation : Qt::Orientation

This property holds the orientation of the slider.

The orientation must be Qt::Vertical or Qt::Horizontal (the default).

Access functions:

Qt::Orientation | orientation () const
void | setOrientation ( Qt::Orientation )

### pageStep : int

This property holds the page step interval.

The larger of two natural steps that a slider provides and typically corresponds to the user pressing PageUp or PageDown.

Defaults to 5 seconds.

Access functions:

int | pageStep () const
void | setPageStep ( int milliseconds )

### singleStep : int

This property holds the single step interval.

The smaller of two natural steps that a slider provides and typically corresponds to the user pressing an arrow key.

Defaults to 0.5 seconds.

Access functions:

int | singleStep () const
void | setSingleStep ( int milliseconds )

### tracking : bool

This property holds whether slider tracking is enabled.

If tracking is enabled (the default), the media seeks while the slider is being dragged. If tracking is disabled, the media seeks only when the user releases the slider.

Access functions:

bool | hasTracking () const
void | setTracking ( bool tracking )

## Member Function Documentation

### SeekSlider::SeekSlider ( MediaObject * media, QWidget * parent = 0 )

Constructs a seek slider widget for the specified media with the given parent.

### SeekSlider::~SeekSlider ()

Destroys the seek slider.

### MediaObject * SeekSlider::mediaObject () const

Return the media object this SeekSlider controls.

See also setMediaObject().

### void SeekSlider::setMediaObject ( MediaObject * media ) `[slot]`
