ChannelStore* QtVision::channels (  )  [inline]

Returns current ChannelStore.

ConfigData* QtVision::config (  )  const [inline]

Returns the current configuration.

KConfig* QtVision::configHandle (  )  const [inline]

Returns the KConfig objectg for this instance.

virtual QtVisionView* QtVision::createScreen (  QWidget * parent = 0, const char * name = 0 )  [virtual]

Factory method for creating the screen the picture will be displayed on. This widget returned will depend on the facilities supported by the TV card and X server (eg. there will be special screen widgets for Xv support). Note that this widget is automatically made the screen for this QtVision object.

int QtVision::brightness (  )

To get various values.

bool QtVision::tryAutoStart (  )  [slot]

Try to start using the previous device. Returns true iff it succeeds.

virtual void QtVision::selectDevice (  )  [virtual, slot]

Ask the user to select a device. Reimplemented from QtVisionIface.

void QtVision::setDevice (  QVSourcePlugin * dev )  [slot]

Set the current video device.

virtual void QtVision::setSource (  const QString & src )  [virtual, slot]

Sets the source to use. Reimplemented from QtVisionIface.

virtual void QtVision::stopDevice (  )  [virtual, slot]

Stop the current device and dispose of it.

void QtVision::setChannel (  Channel * channel )  [slot]

Sets the current current channel.

void QtVision::setChannel (  int channel )  [slot]

Overloaded version of the above method.

virtual void QtVision::channelDown (  )  [virtual, slot]

Changes the channel to the one preceding the current, wrapping round if we are currently showing the first channel. Reimplemented from QtVisionIface.

virtual void QtVision::channelUp (  )  [virtual, slot]

Changes the channel to the one following the current, wrapping round if we are currently showing the last channel. Reimplemented from QtVisionIface.

virtual void QtVision::previousChannel (  )  [virtual, slot]

Recalls the previous channel. Reimplemented from QtVisionIface.

virtual void QtVision::volumeMute (  )  [virtual, slot]

Mutes and unmutes the sound. Reimplemented from QtVisionIface.

virtual void QtVision::volumeUp (  )  [virtual, slot]

Increases the volume. Reimplemented from QtVisionIface.

virtual void QtVision::volumeDown (  )  [virtual, slot]

Decreases the volume. Reimplemented from QtVisionIface.

virtual void QtVision::setVolume (  int left, int right )  [virtual, slot]

Sets the volume. Reimplemented from QtVisionIface.

virtual void QtVision::setVolume (  int vol )  [virtual, slot]
