public class SeekSlider
extends QWidget

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:

    MediaObject moo = new MediaObject();
    AudioOutput device = new AudioOutput();
    Phonon.createPath(moo, device);
    moo.setCurrentSource(new MediaSource("/home/gvatteka/Music/Lumme-Badloop.ogg"));

    SeekSlider slider = new SeekSlider();
    slider.setMediaObject(moo);

    slider.show();
    moo.play();

Method Detail

hasTracking

public final boolean hasTracking()
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.


iconSize

public final QSize iconSize()
This property holds the icon size used for the mute button/icon. The default size is defined by the GUI style.


isIconVisible

public final boolean isIconVisible()
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.


mediaObject

public final MediaObject mediaObject()

See also.
setMediaObject().


orientation

public final Qt.Orientation orientation()
This property holds the orientation of the slider. The orientation must be Qt::Vertical or Qt::Horizontal (the default).


pageStep

public final int pageStep()
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.


setIconSize

public final void setIconSize(QSize size)
This property holds the icon size used for the mute button/icon. The default size is defined by the GUI style.


setIconVisible

public final void setIconVisible(boolean arg__1)
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.


setMediaObject

Defaults to 0.5 seconds.


setTracking

public final void setTracking(boolean tracking)
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.
