I found out that it is possible (and easy) to directly pass a component created in C++ to QML.
So right now, I modified the code pretty much like this:
@
WindowManager::prepareNewView(int stuffId)
{
MyDatabase db;
// Getting something to show in QML from somewhere based on the parameter received
SomeStuff stuff = db.getStuff(stuffId)
// Creating the new context, based on the global one
QQmlContext *context = new QQmlContext(this->rootContext());
// Exposing the object I need to show in QML to the new context
context ->setContextProperty("someStuff", stuff);
// Creating the component
QQmlComponent component(this->engine(), QUrl("qrc:/qml/MyComponent.qml"));
// Creating the istance of the new component using the new context
QQuickItem *newView = qobject_cast<QQuickItem*>(component.create(context));
// Getting the root component (the Rectangle with it mainWindow)
QObject *object = this->rootObject();
// Manually setting the new component as a child of mainWIndow
newView->setParentItem(qobject_cast<QQuickItem*>(object));
// Invoking the QML that will connect the events of the new window, while passing the component created above as QVariant
QMetaObject::invokeMethod(object, "addView", Q_ARG(QVariant, QVariant::fromValue(newView)));
}
@
In QML the function in the main.qml is now like this:
@
// Function called from C++; the param "newView" is the last component added
function addView(newView)
{
// ... Here I would use the new view to connect signals to slots and such as if I created "newView" directly in QML
}
@
So I managed not to change the code too much after all.
