Yes, you can use Loader element or instantiate QML objects from JS/ C++.

Can you post some example? Or link to it?

From QML you can use the Qt.createQmlObject() method:

@object Qt::createQmlObject(string qml, object parent, string filepath)@

Like for example:

@var newObject = Qt.createQmlObject('import QtQuick 2.0; Rectangle {color: "red"; width: 20; height: 20}', parentItem, "dynamicSnippet1");@

From C++:

@QQmlEngine *engine = new QQmlEngine;
QQmlComponent component(engine, QUrl::fromLocalFile("main.qml"));
QObject *myObject = component.create();@

QML "Loader":http://qt-project.org/doc/qt-4.8/qml-loader.html element.

"Dynamic object creation":http://qt-project.org/doc/qt-4.8/qml-qt.html#dynamic-object-creation in QML.
