As with \l ListView, data for each row is provided through a \l model: \code ListModel { id: libraryModel ListElement { title: "A Masterpiece" author: "Gabriel" } ListElement { title: "Brilliance" author: "Jens" } ListElement { title: "Outstanding" author: "Frederik" } } \endcode You provide title and size of a column header by adding a \l TableViewColumn as demonstrated below. \code TableView { TableViewColumn { role: "title" title: "Title" width: 100 } TableViewColumn { role: "author" title: "Author" width: 200 } model: libraryModel } \endcode The header sections are attached to values in the \l model by defining the model role they attach to. Each property in the model will then be shown in their corresponding column. You can customize the look by overriding the \l {BasicTableView::}{itemDelegate}, \l {BasicTableView::}{rowDelegate}, or \l {BasicTableView::}{headerDelegate} properties. The view itself does not provide sorting. This has to be done on the model itself. However you can provide sorting on the model, and enable sort indicators on headers. \list \li int sortIndicatorColumn - The index of the current sort column \li bool sortIndicatorVisible - Whether the sort indicator should be enabled \li enum sortIndicatorOrder - Qt.AscendingOrder or Qt.DescendingOrder depending on state \endlist You can create a custom appearance for a TableView by assigning a \l {TableViewStyle}. */ /*! \qmlproperty model TableView::model This property holds the model providing data for the table view. The model provides the set of data that is used to create the items in the view. Models can be created directly in QML using ListModel, XmlListModel or VisualItemModel, or provided by C++ model classes. \sa ListView::model Example model: \code model: ListModel { ListElement { column1: "value 1" column2: "value 2" } ListElement { column1: "value 3" column2: "value 4" } } \endcode \sa {qml-data-models}{Data Models} */ /*! \qmlproperty int TableView::rowCount The current number of rows */ /*! \qmlproperty int TableView::currentRow The current row index of the view. The default value is \c -1 to indicate that no row is selected. */ /*! \qmlsignal TableView::activated(int row) Emitted when the user activates an item by mouse or keyboard interaction. Mouse activation is triggered by single- or double-clicking, depending on the platform. \a row int provides access to the activated row index. \note This signal is only emitted for mouse interaction that is not blocked in the row or item delegate. The corresponding handler is \c onActivated. */ /*! \qmlsignal TableView::clicked(int row) Emitted when the user clicks a valid row by single clicking \a row int provides access to the clicked row index. \note This signal is only emitted if the row or item delegate does not accept mouse events. The corresponding handler is \c onClicked. */ /*! \qmlsignal TableView::doubleClicked(int row) Emitted when the user double clicks a valid row. \a row int provides access to the clicked row index. \note This signal is only emitted if the row or item delegate does not accept mouse events. The corresponding handler is \c onDoubleClicked. */ /*! \qmlsignal TableView::pressAndHold(int row) \since QtQuick.Controls 1.3 Emitted when the user presses and holds a valid row. \a row int provides access to the pressed row index. \note This signal is only emitted if the row or item delegate does not accept mouse events. The corresponding handler is \c onPressAndHold. */ /*! \qmlmethod void TableView::positionViewAtRow( int row, PositionMode mode ) Positions the view such that the specified \a row is at the position defined by \a mode: \list \li ListView.Beginning - position item at the top of the view. \li ListView.Center - position item in the center of the view. \li ListView.End - position item at bottom of the view. \li ListView.Visible - if any part of the item is visible then take no action, otherwise bring the item into view. \li ListView.Contain - ensure the entire item is visible. If the item is larger than the view the item is positioned at the top of the view. \endlist If positioning the \a row creates an empty space at the beginning or end of the view, then the view is positioned at the boundary. For example, to position the view at the end at startup: \code Component.onCompleted: table.positionViewAtRow(rowCount -1, ListView.Contain) \endcode Depending on how the model is populated, the model may not be ready when TableView Component.onCompleted is called. In that case you may need to delay the call to positionViewAtRow by using a \l [QtQml]{Timer}. \note This method should only be called after the component has completed. */ /*! \qmlmethod int TableView::rowAt( int x, int y ) Returns the index of the visible row at the point \a x, \a y in content coordinates. If there is no visible row at the point specified, \c -1 is returned. \note This method should only be called after the component has completed. */ /*! \qmlproperty Selection TableView::selection \since QtQuick.Controls 1.1 This property contains the current row-selection of the \l TableView. The selection allows you to select, deselect or iterate over selected rows. \list \li function \b clear() - deselects all rows \li function \b selectAll() - selects all rows \li function \b select(from, to) - select a range \li function \b deselect(from, to) - de-selects a range \li function \b forEach(callback) - iterates over all selected rows \li function \b contains(index) - checks whether the selection includes the given index \li signal \b selectionChanged() - the current row selection changed \li readonly property int \b count - the number of selected rows \endlist \b Example: \code tableview.selection.select(0) // select row index 0 tableview.selection.select(1, 3) // select row indexes 1, 2 and 3 tableview.selection.deselect(0, 1) // deselects row index 0 and 1 tableview.selection.deselect(2) // deselects row index 2 \endcode \b Example: To iterate over selected indexes, you can pass a callback function. \a rowIndex is passed as as an argument to the callback function. \code tableview.selection.forEach( function(rowIndex) {console.log(rowIndex)} ) \endcode */ /*! \qmlproperty Component TableView::itemDelegate This property defines a delegate to draw a specific cell. In the item delegate you have access to the following special properties: \list \li styleData.selected - if the item is currently selected \li styleData.value - the value or text for this item \li styleData.textColor - the default text color for an item \li styleData.row - the index of the view row \li styleData.column - the index of the view column \li styleData.elideMode - the elide mode of the column \li styleData.textAlignment - the horizontal text alignment of the column \li styleData.pressed - true when the item is pressed (since QtQuick.Controls 1.3) \li styleData.hasActiveFocus - true when the row has focus (since QtQuick.Controls 1.3) \endlist Example: \code itemDelegate: Item { Text { anchors.verticalCenter: parent.verticalCenter color: styleData.textColor elide: styleData.elideMode text: styleData.value } } \endcode \note For performance reasons, created delegates can be recycled across multiple table rows. This implies that when you make use of implicit properties such as \c styleData.row or \c model, these values can change after the delegate has been constructed. This means that you should not assume that content is fixed when \c Component.onCompleted is called, but instead rely on bindings to such properties. */ /*! \qmlpropertygroup TableView::section \qmlproperty string TableView::section.property \qmlproperty enumeration TableView::section.criteria \qmlproperty Component TableView::section.delegate \qmlproperty enumeration TableView::section.labelPositioning These properties determine the section labels. \sa ListView::section */
