Qt Quick elements from C++ - Creating and destroying - Is it possible?

Question

I would like to use both Qt Quick and Qt Widgets to display the user interface. The problem is I want to create both in C++ code. (The UI isn't defined at time of compilation.) There are no problems with the latter. Unfortunately I cannot find any examples how to create the declarative scene at runtime. It looks it is possible to create a text string with QML code and interpret it. I want something more sane, unfortunately. Is it possible?

I play with QT5, but I am interested in answers about QT4 too.

I believe that this will give you answer: http://www.qtcentre.org/threads/48767-Can-a-QML-element-be-displayed-inside-a-QT-C-GUI

It is possible. Your code should look like this:

// inside custom QGraphicsView class...

...

QGraphicsObject *qmlThing = getQMLGraphicsObjectFromURL(QUrl("pathToYourURL"));
myScene->addItem(qmlThing);

...

QGraphicsObject * MyGraphicsView::getQMLGraphicsObjectFromURL(const QUrl &url) {
QDeclarativeComponent component(new QDeclarativeEngine(), url);
QObject *object = component.create();
return qobject_cast<QGraphicsObject *>(object);
}
