Add text in textarea inside class
-
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

@MrErfan said in add text in textarea inside class:
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.cppMyClass 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 }
