\title Readonly Property
\brief A readonly property was written.
\section1 Cannot Assign To Read-Only Property
\section2 What happened?
A \l{Read-Only Properties}{read-only property} was written.
\section2 Why is this bad?
The QML engine will throw a Type Error when it sees the write to a read-only property.
\section2 Example
\qml
import QtQuick
Item {
id: root
readonly property int someNumber: 10
Component.onCompleted: {
someNumber = 20 // not ok: TypeError: Cannot assign to read-only property
}
}
\endqml
You can fix this warning by removing the write to the read-only property, by writing to another
non-read-only property, or by removing the readonly modifier if the property should no longer be
considered constant.
