Constructor & Destructor Documentation

◆ QQmlTableModel()

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

Encapsulates a simple table model.

\qmltype TableModel

! \nativetype 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}.

◆ appendRow()

void QQmlTableModel::appendRow ( const QVariant & row)

\qmlmethod TableModel::appendRow(object row)

Adds a new row to the end of the model, with the values (cells) in row.

model.appendRow({
checkable: true,
amount: 1,
fruitType: "Pear",
fruitName: "Williams",
fruitPrice: 1.50,
})

insertRow(), setRow(), removeRow()

Definition at line 256 of file qqmltablemodel.cpp.

◆ clear()

void QQmlTableModel::clear ( )

\qmlmethod TableModel::clear()

Removes all rows from the model.

See also
removeRow()

Definition at line 271 of file qqmltablemodel.cpp.

◆ columnCount()

int QQmlTableModel::columnCount ( const QModelIndex & parent = QModelIndex()) const
overridevirtual

\qmlproperty int TableModel::columnCount \readonly

This read-only property holds the number of columns in the model.

The number of columns is fixed for the lifetime of the model after the \l rows property is set or \l appendRow() is called for the first time.

Implements QAbstractItemModel.

Definition at line 607 of file qqmltablemodel.cpp.

◆ dataPrivate()

QVariant QQmlTableModel::dataPrivate ( const QModelIndex & index,
const QString & roleName ) const
overrideprivatevirtual

Implements QQmlAbstractColumnModel.

Definition at line 221 of file qqmltablemodel.cpp.

◆ firstRow()

QVariant QQmlTableModel::firstRow ( ) const
overrideprotectedvirtual

Implements QQmlAbstractColumnModel.

Definition at line 523 of file qqmltablemodel.cpp.

◆ getRow()

QVariant QQmlTableModel::getRow ( int rowIndex)

\qmlmethod object TableModel::getRow(int rowIndex)

Returns the row at rowIndex in the model.

Note that this equivalent to accessing the row directly through the \l rows property:

Component.onCompleted: {
// These two lines are equivalent.
console.log(model.getRow(0).display);
console.log(model.rows[0].fruitName);
}
Note
the returned object cannot be used to modify the contents of the model; use setRow() instead.

◆ index()

QModelIndex QQmlTableModel::index ( int row,
int column,
const QModelIndex & parent = QModelIndex() ) const
overridevirtual

\qmlmethod QModelIndex TableModel::index(int row, int column)

Returns a \l QModelIndex object referencing the given row and column, which can be passed to the data() function to get the data from that cell, or to setData() to edit the contents of that cell.

◆ insertRow()

void QQmlTableModel::insertRow ( int rowIndex,
const QVariant & row )

\qmlmethod TableModel::insertRow(int rowIndex, object row)

Adds a new row to the model at position rowIndex, with the values (cells) in row.

model.insertRow(2, {
checkable: true, checked: false,
amount: 1,
fruitType: "Pear",
fruitName: "Williams",
fruitPrice: 1.50,
})

The rowIndex must point to an existing item in the table, or one past the end of the table (equivalent to \l appendRow()).

◆ moveRow()

void QQmlTableModel::moveRow ( int fromRowIndex,
int toRowIndex,
int rows = 1 )

\qmlmethod TableModel::moveRow(int fromRowIndex, int toRowIndex, int rows)

Moves rows from the index at fromRowIndex to the index at toRowIndex.

The from and to ranges must exist; for example, to move the first 3 items to the end of the list:

model.moveRow(0, model.rowCount - 3, 3)

◆ removeRow()

void QQmlTableModel::removeRow ( int rowIndex,

\qmlmethod TableModel::removeRow(int rowIndex, int rows = 1)

Removes a number of rows at rowIndex from the model.

\qmlproperty int TableModel::rowCount \readonly

This read-only property holds the number of rows in the model.

This value changes whenever rows are added or removed from the model.

◆ rows()

QVariant QQmlTableModel::rows ( ) const

\qmlproperty object TableModel::rows

This property holds the model data in the form of an array of 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
}

◆ setRow()

void QQmlTableModel::setRow ( int rowIndex,
const QVariant & row )

\qmlmethod TableModel::setRow(int rowIndex, object row)

Changes the row at rowIndex in the model with row.

All columns/cells must be present in row, and in the correct order.

model.setRow(0, {
checkable: true,
amount: 1,
fruitType: "Pear",
fruitName: "Williams",
fruitPrice: 1.50,
})

If rowIndex is equal to rowCount(), then a new row is appended to the model. Otherwise, rowIndex must point to an existing row in the model.
