SlideShow Example


Slideshow displays a series of time delayed images after you select a source image directory to use. The folder button presents a list of three options: browse for a directory, load a playlist or enter a location.

This implementation uses a QMediaImageViewer object for the image with a QVideoWidget used to do the display. Whether the the source is a browsed directory, a playlist file or a URL to a local or remote location the playlist object in Slideshow is updated with the file or multiple file locations.

 connect(imageViewer, SIGNAL(stateChanged(QMediaImageViewer::State)),
         this, SLOT(stateChanged(QMediaImageViewer::State)));

 playlist = new QMediaPlaylist;

We create a QVideoWidget to display the viewer and add it to the dialog.

 QVideoWidget *videoWidget = new QVideoWidget;
 layout->addWidget(videoWidget, Qt::AlignCenter);

The timeout between images is set by changing the timeout property in QMediaImageViewer which is in milliseconds. So to change the timeout to five seconds

 imageViewer->setTimeout( 5000 );
