\class QWebEngineFullScreenRequest
\brief The QWebEngineFullScreenRequest class enables accepting or rejecting
requests for entering and exiting the fullscreen mode.
\since 5.6
\inmodule QtWebEngineCore
To allow elements such as videos to be shown in the fullscreen mode,
applications must set QWebEngineSettings::FullScreenSupportEnabled and
connect to QWebEnginePage::fullScreenRequested, which takes a
QWebEngineFullScreenRequest instance as an argument.
If an element of a web page requests to be shown in the fullscreen mode,
QWebEnginePage::fullScreenRequested will be emitted with an
QWebEngineFullScreenRequest instance as an argument where toggleOn() returns
\c true. The signal handler needs to then either call accept() or reject().
If the request to enter the fullscreen mode is accepted, the element
requesting fullscreen mode will fill the viewport, but it is up to the
application to make the view fullscreen or to move the page to a view that
is in the fullscreen mode.
Likewise, a QWebEnginePage::fullScreenRequested will be emitted when
the user wants to leave the full screen mode (that is, through the
QWebEnginePage::ExitFullScreen context menu action). In this case,
toggleOn() will return \c false, and the signal handler again needs to
accept() or reject() the request. If it is accepted, the applicaton needs to
make sure that the global window state is restored.
