Detailed Description

QAbstractListModel view of the live toplevel set.

Translates ForeignToplevelManager's toplevelAdded / toplevelRemoved signals into proper beginInsertRows / beginRemoveRows model events, so a Repeater { model: Toplevels.model } patches one delegate in / out per change instead of rebuilding the whole list (which is what happens when model: is bound to a QList<...> value property — every change re-evaluates the binding and resets every delegate).

Roles:

• toplevel — the ForeignToplevel* for the row.

Usage from QML:

Repeater {
    model: Toplevels.model
    delegate: Rectangle {
        required property var toplevel
        Text { text: toplevel.title }
    }
}
