[SOLVED] QtQuick-Plugin - get QmlViewer object

selectedOne

Hi guys,

i wrote a QtQuick-Plugin in C++.
One of my Classes should be possible to manipulate the QmlViewer.

So... when an Object of my Class is created by the QmlViewer i want to get a pointer to the QmlViewer Object.
Does anyone know a way to get the QmlViewer Object in a QtQuick-Plugin Class?

Btw, using Qt 4.8.4 with Creator 2.5.2 on Windows.

Hi Mark,

In Qt4, QtQuick items are a subclass of QDeclarativeItem.

QDeclarativeItem has a member function:

@QGraphicsScene * QGraphicsItem::scene () const@

which returns the scene your item is created in,

Scene itself has a member function:

@QList<QGraphicsView *> QGraphicsScene::views () const@

which returns the views that are rendering the scene.

your QmlViewer is probably a subclass of the first item in this QList ?

When I said QmlViewer I meant the Qt qmlviewer.exe.
So you solved my problem.

The thing is, is have an application which loads n instances of the qml viewer as an DLL.
My QtQuick item has an static List which collects the pointers of all created elements of this type.
And with the QGraphicsItem::scene () mehod I can find out, which elements are on the same qml viewer page. :)
