how to edit the property of dynamically created object?

NixUhs

according to the tutorial，Qml can use createComponent() + createObject() to dynamically create objects
but how to edit the property of these objects
For example：
//dyRec.qml
Rectangle {
id: rect
TextEdit {
id: rectText
text: qsTr("Default")
}
}

//main.qml
Window {
id: root
var dyRect = Qt.createComponent("dyRec.qml")
var dyRectObj = dyRect.createObject(root)
//Here I want to edit the text of TextEdit in Rectangle, how to do it
dyRectObj.rectText.text = qsTr("1111") //<--Error
}

You need to expose the text as a property. The id you set in your QML file is local - visible only inside of that same file. When you try to access it from another file (main.qml), it will never work. Does not matter if it is a dynamic component or not.

So, for example:

//dyRec.qml
Rectangle {
  property alias text: rectText.text
  id: rect
  TextEdit {
    id: rectText
    text: qsTr("Default")
  }
}

// main.qml
var dyRect = Qt.createComponent("dyRec.qml")
var dyRectObj = dyRect.createObject(root)
dyRectObj.text = qsTr("1111")
