Detailed Description
To allow web applications to capture contents of a display, applications must connect to QWebEnginePage::desktopMediaRequested, which takes a QWebEngineDesktopMediaRequest instance as an argument.
If a web application requests access to the contents of a display, QWebEnginePage::desktopMediaRequested will be emitted with a QWebEngineDesktopMediaRequest instance as an argument which holds references to QAbstractListModels for available windows and screens that can be captured.
The data model's Qt::DisplayRole specifies the name of the source which is the title of a window or the number of the display. The model is dynamically updates if the available list of sources has changed e.g a window is opened/closed.
The signal handler needs to then either call QWebEngineDesktopMediaRequest:selectScreen() or QWebEngineDesktopMediaRequest::selectWindow() to accept the request and start screensharing.
