Qt3D - Retrieving Qml Viewport Element as C++ Object
-
Hey guys,
I've been messing around with Qt5 and Qt3D / Quick3D a bit but I getting stuck trying to retrieve my qml Viewport Element as a c++ Viewport object.
I can't seem to find the Viewport class include which is not indicated in the documentation :
http://qt-project.org/doc/qt-5.0/qml-viewport.html
http://doc-snapshot.qt-project.org/5.0/viewport.html
I don't know if it's because it's deprecated or on the contrary not finalized yet.Then I'd like to make sure I'm retrieving my object the right way so I've posted a sample of my code :
@
bool QmlViewManager::initView()
{
// SET STARTING QML FILE
this->viewer->setSource(QUrl::fromLocalFile("qml/Tepee3DSampleApp/main.qml"));
this->viewer->show();
//CONTROLLER BETWEEN QML VIEW AND MODELS
this->viewer->rootContext()->setContextProperty("controller", this);
// GET ROOT QML OBJECT
this->rootQmlObject = this->viewer->rootObject();
// SET SCREESIZE IN ROOT OBJECT
this->rootQmlObject->setProperty("width", this->desktopWidget->screenGeometry(-1).width());
this->rootQmlObject->setProperty("height", this->desktopWidget->screenGeometry(-1).height());
// SHOW QML FILE IN FULLSCREEN
QObject *tmpObj;
if ((tmpObj = this->rootQmlObject->findChild<QObject >("viewport")))
{
this->viewport = (Viewport)tmpObj;
std::cout << "ViewPort found" << std::endl;
}
if ((tmpObj = this->rootQmlObject->findChild<QObject >("root3dObject")))
{
this->root3dObject = (QQuickItem)tmpObj;
std::cout << "Root3dObject found" << std::endl;
}
}
@Any help will be very appreciated.
Thanks

For those interested, you can't really retrieve a Viewport directly from qml as it is a QQuickItem. So either you retrieve it as a QQuickItem* and then try to insert your 3D items in it (not tested but it should work) or you do this on the qml side using loaders.
