How To C++ output to QML Text Element

[alfalive]

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.

For example

@
Text {
id: mytext
text: "Hello"
}
@

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.

I use:
Ubuntu 14.04
QtCreator 3.1.1
Based on Qt 5.2.1 (GCC 4.8.2, 64 bit)
Built on Jul 2 2014 at 11:57:41

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++".

1. In order to integrate with Qml and Qt you need to create the Qt Quick UI application.
2. 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();
