## Property Documentation

layoutDirection : enumeration

This property holds the layout direction of the column layout - it controls whether items are laid out from left ro right or right to left. If `Qt.RightToLeft` is specified, left-aligned items will be right-aligned and right-aligned items will be left-aligned.

Possible values:

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

This property was introduced in QtQuick.Layouts 1.1.

See also GridLayout::layoutDirection and RowLayout::layoutDirection.

spacing : real

This property holds the spacing between each cell. The default value is `5`.
