详细描述

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 updated if the available list of sources has changed; e.g when a window is opened/closed.

The signal handler needs to then either call selectScreen () 或 selectWindow () to accept the request and start screensharing.
