Signals inherited from QAbstractItemModel
void	dataChanged (const QModelIndex &topLeft, const QModelIndex &bottomRight, const QList< int > &roles=QList< int >())

◆ QQmlTableModel()

QT_BEGIN_NAMESPACE QQmlTableModel::QQmlTableModel ( QObject * parent = nullptr )

Encapsulates a simple table model.

\qmltype TableModel

! \instantiates QQmlTableModel \inqmlmodule Qt.labs.qmlmodels

Since: 5.14

The TableModel type stores JavaScript/JSON objects as data for a table model that can be used with \l TableView. It is intended to support very simple models without requiring the creation of a custom QAbstractTableModel subclass in C++.

import QtQuick
import QtQuick.Window
import Qt.labs.qmlmodels
 
Window {
    width: 400
    height: 400
    visible: true
 
    TableView {
        anchors.fill: parent
        columnSpacing: 1
        rowSpacing: 1
        boundsBehavior: Flickable.StopAtBounds
 
        model: TableModel {
            TableModelColumn { display: "checked" }
            TableModelColumn { display: "amount" }
            TableModelColumn { display: "fruitType" }
            TableModelColumn { display: "fruitName" }
            TableModelColumn { display: "fruitPrice" }
 
            // Each row is one type of fruit that can be ordered
//![rows]
            rows: [
                {
                    // Each property is one cell/column.
                    checked: false,
                    amount: 1,
                    fruitType: "Apple",
                    fruitName: "Granny Smith",
                    fruitPrice: 1.50
                },
                {
                    checked: true,
                    amount: 4,
                    fruitType: "Orange",
                    fruitName: "Navel",
                    fruitPrice: 2.50
                },
                {
                    checked: false,
                    amount: 1,
                    fruitType: "Banana",
                    fruitName: "Cavendish",
                    fruitPrice: 3.50
                }
            ]
//![rows]
        }
//![delegate]
        delegate:  TextInput {
            text: model.display
            padding: 12
            selectByMouse: true
 
            onAccepted: model.display = text
 
            Rectangle {
                anchors.fill: parent
                color: "#efefef"
                z: -1
            }
        }
//![delegate]
    }
}

The model's initial row data is set with either the \l rows property or by calling \l appendRow(). Each column in the model is specified by declaring a \l TableModelColumn instance, where the order of each instance determines its column index. Once the model's \l Component::completed() signal has been emitted, the columns and roles will have been established and are then fixed for the lifetime of the model.

To access a specific row, the \l getRow() function can be used. It's also possible to access the model's JavaScript data directly via the \l rows property, but it is not possible to modify the model data this way.

To add new rows, use \l appendRow() and \l insertRow(). To modify existing rows, use \l setRow(), \l moveRow(), \l removeRow(), and \l clear().

It is also possible to modify the model's data via the delegate, as shown in the example above:

        delegate:  TextInput {
            text: model.display
            padding: 12
            selectByMouse: true
 
            onAccepted: model.display = text
 
            Rectangle {
                anchors.fill: parent
                color: "#efefef"
                z: -1
            }
        }

If the type of the data at the modified role does not match the type of the data that is set, it will be automatically converted via \l {QVariant::canConvert()}{QVariant}.
