Get the value of QML Editbox from C++

I have created a QtQuick application with some textboxes in QML. I want to use the value of those textboxes in my c++ code. So how can I fetch those values from C++ code?

Solution

  • It can be like:

    QML file:

    Item{
id: root

signal textChanged(string msg)

TextInput
{
    id: inputText
    anchors.horizontalCenter: root.horizontalCenter
    anchors.verticalCenter: root.verticalCenter

    text : ""
    inputMethodHints: Qt.ImhNoPredictiveText
    selectByMouse: true

    onAccepted: { 
        inputText.focus = false; 
        Qt.inputMethod.hide(); 
        root.textChanged(inputText.text); 
    }

 }
}

    ِYou can connect the signal of your qml to some slot in cpp like:

    QObject::connect((QObject *)viewer.rootObject(), SIGNAL(textChanged(QString)), this, SLOT(someSlot(QString)));
