Constructor & Destructor Documentation

QQmlDelegateModelPrivate()

QQmlDelegateModelPrivate::QQmlDelegateModelPrivate

(

QQmlContext *

ctxt

)

Encapsulates a model and delegate.

\qmltype DelegateModel

! \instantiates QQmlDelegateModel \inqmlmodule QtQml.Models

The DelegateModel type encapsulates a model and the delegate that will be instantiated for items in the model.

It is usually not necessary to create a DelegateModel. However, it can be useful for manipulating and accessing the \l modelIndex when a QAbstractItemModel subclass is used as the model. Also, DelegateModel is used together with \l Package to provide delegates to multiple views, and with DelegateModelGroup to sort and filter delegate items.

DelegateModel only supports one-dimensional models – assigning a table model to DelegateModel and that to TableView will thus only show one column.

The example below illustrates using a DelegateModel with a ListView.

import QtQuick
import QtQml.Models
 
Rectangle {
    width: 200; height: 100
 
    DelegateModel {
        id: visualModel
        model: ListModel {
            ListElement { name: "Apple" }
            ListElement { name: "Orange" }
        }
        delegate: Rectangle {
            height: 25
            width: 100
            Text { text: "Name: " + name}
        }
    }
 
    ListView {
        anchors.fill: parent
        model: visualModel
    }
}
