Hi,

I test free touch keyboard in QML. It works. please tell me how pass text from keyboard to Qt. Below tested keyboard:

    KeyboardInput {
        label: 'text to send'
        anchors.centerIn: parent
        color: "gray"
        width: 1000
        height: 50
        onAccepted: print('onAccepted', text)
    }

I would like to pass the text variable to qt.

class in qt

Please write "class in C++". QML is also part of Qt.

Did you read https://doc.qt.io/qt-5/qtqml-cppintegration-topic.html ?

What do you mean?
Do you want to pass the text to C++ part of your application?

Exactly.
To better explanation , when I write text in Textinput I get qml: onAccepted exampletext
and next I would like pass this text to my class in qt.

But I don't know why is the error:

qrc:/UI/Accessories/KeyboardController.qml:35:5: QML Connections: Implicitly defined onFoo properties in Connections are deprecated. Use this syntax instead: function onFoo(<arguments>) { ... }
qml: onAccepted exampletext

Thanks for suggestion. It works!

I wrote class SystemController and generate code from macro Q_PROPERTY(QString text2Print READ text2Print WRITE setText2Print NOTIFY text2PrintChanged)

and registered my class in qml:
SystemController { id: systemController }

Next I change in my .qml code:

KeyboardInput {
        label: 'insert text'
        onAccepted: print('onAccepted', systemController.text2Print = text)
    }

Can you help me with below error, How can I remove this?

qrc:/UI/Accessories/KeyboardController.qml:35:5: QML Connections: Implicitly defined onFoo properties in Connections are deprecated. Use this syntax instead: function onFoo(<arguments>) { ... }

Here is a line with a problem:

    Connections {
        target: keyboard
        onAccepted: {
            root.accepted(text) // emit
            keyboard.destroy()  // hide
        }
        onRejected: keyboard.destroy() // hide
    }

It is warning, But can you try? Text is not passed to the func explicitly

        onAccepted(text): {
            root.accepted(text) // emit
            keyboard.destroy()  // hide
        }

Instead of

Connections {
onAccepted: ...

you need to write

Connections {
function onAccepted(..) { }
