QML front end in CPP: compile/linker trouble
-
I am using VS2010 with qt 5.2.1
I have been working on a UI in QML and trying to integrate it into my C++ project, I tried
@#include <QDeclarativeView>@
like "this suggests doing.":http://qt-project.org/doc/qt-4.8/qdeclarativeview.html#details
however, I get compiler errors saying that QDeclarativeView cannot be found. so I googled and after adding
@QT+= quick@
didn't work,was tried a QQuickView instead. this time including QtQuick/QQuickView worked. so I tried the following
@ QQuickView *view = new QQuickView;
view->setSource(QUrl::fromLocalFile("main.qml");
view->show();@and this gets all sorts of ridiculous linker errors, and now I have no idea what to try.

Can you try putting QT += qml quick as well ? Suggest you clean and rebuild. Can you try creating the QtQuick UI application itself ? This puts all the necessary things for you.

Try
@
#include <QtQuick>
