It is available as a convenience for developers, as it offers a cleaner API.

Items in a ColumnLayout support these attached properties:

- Layout.minimumWidth
- Layout.minimumHeight
- Layout.preferredWidth
- Layout.preferredHeight
- Layout.maximumWidth
- Layout.maximumHeight
- Layout.fillWidth
- Layout.fillHeight
- Layout.alignment
- Layout.margins
- Layout.leftMargin
- Layout.rightMargin
- Layout.topMargin
- Layout.bottomMargin

     ColumnLayout{
         spacing: 2

         Rectangle {
             Layout.alignment: Qt.AlignCenter
             color: "red"
             Layout.preferredWidth: 40
             Layout.preferredHeight: 40
         }

         Rectangle {
             Layout.alignment: Qt.AlignRight
             color: "green"
             Layout.preferredWidth: 40
             Layout.preferredHeight: 70
         }

         Rectangle {
             Layout.alignment: Qt.AlignBottom
             Layout.fillHeight: true
             color: "blue"
             Layout.preferredWidth: 70
             Layout.preferredHeight: 40
         }
     }

## Property Documentation

[since QtQuick.Layouts 1.1] layoutDirection : enumeration

This property holds the layout direction of the column layout - it controls whether items are laid out from left to 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`.
