I have QMainwindow as Mainwindow. In the MainWindow, there is a QQuickWidget and a QDockWidget. The QDockWidget is floating. And the QDockWidget is used for contain a QWebEngineView.
When I close the MainWindow, the QWebEngineView can not be closed.
@SGaist My Qt version is 5.11.1. My platform is win10, and use the qt vs plugin to complie.
The QDockWidget is floatiing on the MainWindow. And the QWebEngineView is a child window in the QDockWidget, not CentralWindow in MainWindow.
