Add text in textarea inside class

MrErfan

hi
I want to add some value to the Textarea control inside a function cpp class.
In the widgets project, it was very easy to do inside the function.

void MyClass::onNumberChanged(QString Number,int num)
{
    ui->txt->appendPlainText(Number);
}

But I'm lost in Qml
Please guide me
tnaks...

@MrErfan I'm not quite sure what the problem is:

this

onNumberChanged: myTextArea.text = myTextArea.text + Number

doesn't work for you?

MrErfan

Thanks for the answer, where do I use it?

Well you've been very vague with your description: so a quick example:

import QtQuick 2.9

Rectangle{
    id:root
     property int number: 0
     onNumberChanged: myText.text = myText.text  + " " + number

    Timer{
    interval: 1000
    repeat: true
    running: true
    onTriggered: number = number +1
    }

   Text{
    id:myText
    anchors.fill: parent;
    font.pixelSize: 20
    horizontalAlignment: Qt.AlignHCenter
    verticalAlignment:  Qt.AlignVCenter
  }

}

Edit: fixed typo: font.size: 20 =>font.pixelSize: 20

I want to create numbers that within the class MyClass,
Send to TextEdit (qml)

MyClass::MyClass(QObject *parent) : QObject(parent)
{
    mThread = new MyThread(this);
    connect(mThread,SIGNAL(NumberChanged(QString,int)),this,SLOT(onNumberChanged(QString,int)));
}

public slots:
    void onNumberChanged(QString,int);
void MyClass::onNumberChanged(QString Number,int num)
{
    //Send Number from myclass to qml textedit
}

Hello, see this : http://doc.qt.io/qt-5/qtqml-cppintegration-topic.html
to create your own QML Type "MyClass" with ' qmlRegisterType<MyClass>("io.qt.myClass", 1, 0, "MyClass"); '

then you can create a MyClass{ } Item in qml and bind properties :

MyClass{
   onNumberChanged : txEdit.text += number
}
TextEdit{
  id: txEdit
}

You can also embed c++ object into QML; see here : http://doc.qt.io/qt-5/qtqml-cppintegration-contextproperties.html // I think this is what you need
Using this you have nothing to do
//main.cpp

MyClass obj;
engine.rootContext()->setContextProperty("myObject",&obj)
```;
//main.qml

TextEdit{
   text : "your text" +  myObject.myQPrperty  // it will update automatical

   //using this way, variables must be QProperties and Methods must be QINVOKABLES to use from QML
}
