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

[qmlLearner]

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!
