\qmlproperty enumeration QtQuick::Grid::horizontalItemAlignment \qmlproperty enumeration QtQuick::Grid::verticalItemAlignment \qmlproperty enumeration QtQuick::Grid::effectiveHorizontalItemAlignment

Since: 5.1

Sets the horizontal and vertical alignment of items in the Grid. By default, the items are vertically aligned to the top. Horizontal alignment follows the layoutDirection of the Grid, for example when having a layoutDirection from LeftToRight, the items will be aligned on the left.

The valid values for horizontalItemAlignment are, Grid.AlignLeft, Grid.AlignRight and Grid.AlignHCenter.

The valid values for verticalItemAlignment are Grid.AlignTop, Grid.AlignBottom and Grid.AlignVCenter.

The below images show three examples of how to align items.

When mirroring the layout using either the attached property LayoutMirroring::enabled or by setting the layoutDirection, the horizontal alignment of items will be mirrored as well. However, the property horizontalItemAlignment will remain unchanged. To query the effective horizontal alignment of items, use the read-only property effectiveHorizontalItemAlignment.
