Hello,

I'm new in Qt-Quick and QML.

I'm learning how to use it with C++.
So I start with this tutorial and I use Q_PROPERTY(QString userName READ userName WRITE setUserName NOTIFY userNameChanged) :
https://doc.qt.io/qt-5/qtqml-cppintegration-topic.html

with the only difference that I use pageform.ui.qml files.

so on a pageforme I have a text field:
Qt Code: 
  1. TextField {
  2.         id: textfield
  3.         text: "Text"
  4.         placeholderText: qsTr("User name")
  5.         anchors.centerIn: parent
  6.  
  7.     }
To copy to clipboard, switch view to plain text mode 

and in main.qml:
Qt Code: 
  1. Page3Form {
  2.             textfield
  3.             {
  4.                 text: backend.userName
  5.                 onTextChanged: backend.userName = text
  6.             }
  7. }
To copy to clipboard, switch view to plain text mode 


if I use it like that onTextChaned doesn't works and I've got an error in the debugger console:
Qt Code: 
  1. qrc:/main.qml:51: ReferenceError: text is not defined
To copy to clipboard, switch view to plain text mode 

But if I do this in main.qml :
Qt Code: 
  1. Page3Form {
  2.             textfield
  3.             {
  4.                 text: backend.userName
  5.                 onTextChanged: backend.userName = textfield.text
  6.             }
  7. }
To copy to clipboard, switch view to plain text mode 

It works but I have this message:
Qt Code: 
  1. qrc:/Page3Form.ui.qml:25:5: QML TextField: Binding loop detected for property "text"
To copy to clipboard, switch view to plain text mode 

is someone has a clue?

Regards.
