Detailed Description

The VideoRingtone class provides an interface to the Qt Extended media system to play the video tones for incoming calls.

The VideoRingtone acts as a bridge between RingControl and other part of the system that is interested in displaying the video widget, for example, CallScreen.

The RingControl class communicates with this class via messages on the QPE/VideoRingtone QCop channel. The following messages are supported.

playVideo(QString)This message is forwarded to playVideo().
stopVideo()This message is forwarded to stopVideo().
videoRingtoneFailed()This message is equivalent to the videoRingtoneFailed() signal.

RingControl calls playVideo() when the video ringtone is preferred. The CallScreen should be listening to the videoWidgetReady() signal to retreive the video widget object by calling videoWidget().

The signal videoRingtoneStopped() is emitted when the tone finished playing.

    CallScreen::CallScreen() {
        VideoRingtone *vrt = qtopiaTask<VideoRingtone>();
        if ( vrt )
            connect( vrt, SIGNAL(videoWidgetReady()),
                this, SLOT(showVideo()) );

    CallScreen::showVideo() {
        VideoRingtone *vrt = qtopiaTask<VideoRingtone>();
        if (!vrt)
        QWidget *widget = vrt->videoWidget();

        // set the new parent to manage resource
        widget->setParent( this );

        layout()->addWidget( widget );

This class is a Qt Extended server task and is part of the Qt Extended server. It cannot be used by other Qt Extended applications.
