Provides a C++ widget class for displaying a Qt Quick user interface.
The Qt Quick Widgets module is a convenience wrapper for
QQuickWindow . It will automatically load and display a QML scene when given the URL of the main
qml file. Alternatively, you can instantiate QML objects using
QQmlComponent and place them in a manually set-up
QQuickWidget *view = new QQuickWidget; view->setSource(QUrl::fromLocalFile("myqmlfile.qml")); view->show();
QQuickWidget also manages resizing the view and the root item. By default, the
resizeMode is set to
SizeViewToRootObject , which will load the component and resize it to fit the view. Alternatively, you can set
SizeViewToRootObject , which will resize the view to the root item.
