[solved]Unable to assign fix height to TextArea in ColumnLayout

  • Unfortunately, I am not able to set the height of a TextArea in a ColumnLayout. The property height doesn't seem to have any influence on the displayed height of the TextArea. Code snipped:
    import QtQuick 2.2
    import QtQuick.Controls 1.1
    import QtQuick.Layouts 1.1

    Rectangle {
    id: mainRect
    width: 200
    height: 200

    ColumnLayout {
        id: colLayout
        anchors.fill: parent
        Label { text: qsTr("Label") }
        TextArea {
            text: "This wants to grow horizontally and should have a fixed height"
            Layout.fillWidth: true
            //Layout.fillHeight: false
            height: 30
            //Layout.height: 40 // => non-existent property "height"
        Button {
            text: "Button"


    How can I fix this? Do I have to use another property?
    Thank you for any help!

    PS: If I use Column, the height of the TextArea behaves correctly. (But then there is an issue with the width, which is why I would prefer to use ColumnLayout...)

  • The height property is ignored because the layout will anyway set this for you. (i.e hardcoding the height is not very meaningful in a stretchable layout, since the layout itself will set the height property for you) What you want is to set either the items implicitHeight or more specifically Layout.preferredHeight instead.

  • Very nice... Layout.preferredHeight is exactly what I was looking for! Thank you very much!
