Hi,

It seems you need some sort of communication between C++ and QML. Have a look at "Integrating QML and C++":http://doc.qt.io/qt-5/qtqml-cppintegration-topic.html document.

Is it possible to integrate opencv namedwindow with QML ? as it is an important part of my application where the user needs to interact with this window

Yes. Basically you have to wrap the code inside QObject or QQuickItem derived clasess and register them as QML instantiable types. Try googling "qml opencv" to find some example projects.

Okay and i already have Qt 5.4 installed so which version of Qt quick should install?

Since Qt 5.4 is installed QtQuick 2.4 should be there already.

Hi,

"LiveCV":http://livecv.dinusv.com might be interesting in your case if your application is GPL
