How To C++ output to QML Text Element
In short: I tried several tutorials and can not find out how to send my 'cout' to an qml file Text element to change the text in it.
It shows a window with "Hello" text in it. And I want to change that text from cpp file to "Bye" for example.
I tried to understand how Signals and Slots are working but most tutorials are either incompatible with my version of qt or to difficult to follow for me.
Based on Qt 5.2.1 (GCC 4.8.2, 64 bit)

Here is my timer application from some tutorial running in terminal: "MyTimerTest":https://drive.google.com/folderview?id=0B5fK4Qk7cdfnQmVweWgycktwSTA&usp=sharing
welcome to forum. Refer the Qt assistant for "Integrating QML to C++".
- In order to integrate with Qml and Qt you need to create the Qt Quick UI application.
- You need to expose the C++ Qobject to QML
Qt Assistant has good Tutorial and examples. You should get them now.
Just I have pasted sample of main.cpp here.
QGuiApplication a(argc, argv); QQuickView view; view.setSource(QUrl("qrc:/app.qml")); QQmlEngine *eng = view.engine(); QQmlContext *cont = eng->rootContext(); MyTimer mTimer; cont->setContextProperty("MTimer",&mTimer); // Create an instance of my timer view.show();
I am now one step further.
If you need complete example drop an email to me. I will send the complete sample of the above.
