Detailed Description

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 Qt Quick Layouts Overview for more information.

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

Items in a ColumnLayout support these attached properties:

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

layoutDirection : enumeration [since QtQuick.Layouts 1.1]

Qt.RightToLeftItems 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.


uniformCellSizes : bool [since QtQuick.Layouts 6.6]

If this property is set to true, the layout will force all cells to have a uniform size.
