Unable to assign QJSValue to QColor

Mark81

As stated here:

http://doc.qt.io/qt-5/qtqml-cppintegration-data.html

and here:

http://doc.qt.io/qt-5/qml-color.html

QColor types should be automatically converted to color when passed to QML. Instead I receive the error:

Unable to assign QJSValue to QColor

Here the relevant declarations in my class:

Q_PROPERTY(QColor color READ color WRITE setColor NOTIFY colorChanged)
QColor color() { return m_color; }
QColor m_color;

On QML side:

import QtQuick 2.0
ListModel { id: myModel }
function() {
    myModel.append( {
        "myColor": myClass.color
    } )
}
// in delegate
Rectangle {
    width: 200
    height: 200
    color: myColor
}

Hi @Mark81,
As per the docs:

Values must be simple constants; either strings (quoted and optionally within a call to QT_TR_NOOP), boolean values (true, false), numbers, or enumeration values (such as AlignText.AlignHCenter).

So IMO a QColor cannot be assigned to the role myColor. And this in turn causes problem in the delegate.
