\qmltype GridLayout

! \instantiates QQuickGridLayout \inherits Item \inqmlmodule QtQuick.Layouts

Provides a way of dynamically arranging items in a grid.

To be able to use this type more efficiently, it is recommended that you understand the general mechanism of the Qt Quick Layouts module. Refer to \l{Qt Quick Layouts Overview} for more information.

If the GridLayout is resized, all items in the layout will be rearranged. It is similar to the widget-based QGridLayout. All visible children of the GridLayout element will belong to the layout. If you want a layout with just one row or one column, you can use the \l RowLayout or \l ColumnLayout. These offer a bit more convenient API, and improve readability.

By default items will be arranged according to the \l flow property. The default value of the \l flow property is GridLayout.LeftToRight.

If the \l columns property is specified, it will be treated as a maximum limit of how many columns the layout can have, before the auto-positioning wraps back to the beginning of the next row. The \l columns property is only used when \l flow is GridLayout.LeftToRight.

GridLayout {
    id: grid
    columns: 3
 
    Text { text: "Three"; font.bold: true; }
    Text { text: "words"; color: "red" }
    Text { text: "in"; font.underline: true }
    Text { text: "a"; font.pixelSize: 20 }
    Text { text: "row"; font.strikeout: true }
}

The \l rows property works in a similar way, but items are auto-positioned vertically. The \l rows property is only used when \l flow is GridLayout.TopToBottom.

You can specify which cell you want an item to occupy by setting the \l{Layout::row}{Layout.row} and \l{Layout::column}{Layout.column} properties. You can also specify the row span or column span by setting the \l{Layout::rowSpan}{Layout.rowSpan} or \l{Layout::columnSpan}{Layout.columnSpan} properties.

Items in a GridLayout support these attached properties:
\list
    \li \l{Layout::row}{Layout.row}
    \li \l{Layout::column}{Layout.column}
    \li \l{Layout::rowSpan}{Layout.rowSpan}
    \li \l{Layout::columnSpan}{Layout.columnSpan}
    \input layout.qdocinc attached-properties
\endlist

Possible values:

\value Qt.LeftToRight (default) Items are laid out from left to right. \value Qt.RightToLeft Items are laid out from right to left.
