I tried this solution and it doesn't work . :/
Did you change also change the update method?
QString Mode= ui->modecommande->currentText(); // this is a combobox qDebug() << Mode << "this is Mode select commande" ; ui->m_back.setdirectiontext(Mode); -
@dziko147 said in C++ data didn't update in Qml:
@KroMignon No ,
Can you suggest a method ?I don't understand what you mean, please be more clear.
No what?- No you don't have change the update method?
- After changing the update method, the QML didn't be update?

@KroMignon the update method is in another class .
So how can get this m_back :)

So excuse meif my question is stupid :)I don't want to hurt you, but this has nothing to do with Qt, this is C++ basic.
Do you have any knowledge about C++ programming?
Do you know what is a class?
Do you know what is a class method or member?Please take time to got basic knowledge about the programming language you want to use.
There are many C++ tutorials available, take one and do at least the first step to understand what you are doing.Basic C++ knowledge is mandatory if you want to program with Qt which is a C++ framework.

@KroMignon I know how to use class/object .
I know how to manipulate c++ .
But my problem is how can get this in my second classm_ui->quickWidget->rootContext()->setContextProperty("backend", &m_back); -

Again, this is C++ basic => variable scope and life-cycle:
