Qt regexp on QRect

I have a QRect which I try to filter in qml using RegExpFilter QRect(1220,50, 500, 300)

I want to match them like that: QRect([0-2000], [0-500], *, *)

SortFilterProxyModel
{
    onCountChanged: listView.recalculate()
    id: proxyModel
    sourceModel: m_sourceModel
    filters: [
        RegExpFilter {
            enabled: true 
            roleName: "myQRectRole"

            pattern: ????
        }
    ]
}

I am stuck as it is a QRect, is it even possible?

(using SortFilterProxyModel and RegExpFilter)

RegExpFilter only serves to filter strings, in your case it is not. The solution is use ExpressionFilter:

SortFilterProxyModel {
    id: proxyModel
    sourceModel: m_sourceModel
    filters: [
        ExpressionFilter{
            //  QRect([0-2000], [0-500], *, *)
            expression: (model.myQRectRole.x >= 0 && model.myQRectRole.x <= 2000) && (model.myQRectRole.y >= 0 && model.myQRectRole.y <= 500)
        }
    ]
}

In the following link there is an example.
