TextArea.flickable: TextArea {} - non-existent attached object

magicDM

In application for some reason doesn't work attached property TextArea.flickable: TextArea { text: "someText"; }. Example, that simulate problem:

import QtQuick 2.11
import QtQuick.Controls 2.2
import QtQuick.Window 2.12

Window {
    id: appWindow
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    Rectangle {
        property var title: "Example"
        border {
            color: "red"
        }

        width: 420
        height: 160

        Flickable {
            anchors.fill: parent
            TextArea.flickable: TextArea { // here error non-existent attached object
                text: "Non-existent attached object"
            }
        }
    }
}

There is no error in the example, but in my case an error occurs. Tell me what need to check to fix the error?

Note: this code work fine in my case:

Flickable {
            anchors.fill: parent
            TextArea {
                text: "Non-existent attached object"
            }
        }

This property was added in Qt 5.7, so you need a different import statement:

import QtQuick.Controls 2.7

Or, since you are using Qt 5.11:

import QtQuick.Controls 2.11

@sierdzio said in TextArea.flickable: TextArea {} - non-existent attached object:

ick.Controls 2.7

https://doc.qt.io/qt-5/qtquickcontrols-index.html#versions, these versions doesn't exist

import QtQuick.Controls 2.7 // doesn't exist

import QtQuick.Controls 2.11 // doesn't exist

import QtQuick.Controls 2.4 - are also didn't help

I don't know, perhaps you have found a bug.

The code looks correct (although that attached property and the way it is supposed to be used is an abomination).
