RowLayout width can't change

white

Hello , I would like make the 'RowLayout' fill in the whole area like the parent rectangle.

I am using the following code :

import QtQuick 2.12

import QtQuick.Controls 1.4
import QtQuick.Layouts 1.12
ApplicationWindow {
visible: true
width: 640
height: 480
title: qsTr("Scroll")

Rectangle {
    id: inforWindow
    anchors.fill: parent
    color: "green"
    ColumnLayout {
        width: parent.width
        height: parent.height
        //Layout.fillWidth: true
        //Layout.fillHeight: true
        TextArea {
            id: inforText
            width: parent.width


            Layout.fillHeight: true
        }
        RowLayout {
            id:inforInput
            width: parent.width
            spacing: 6
            Layout.preferredHeight: 30
            Layout.minimumHeight:  30
            Layout.maximumHeight: 30

            ComboBox {
                id: inforCombox

                Layout.alignment : Qt.AlignLeft
            }

            Button {

                Layout.alignment : Qt.AlignRight
                text: qsTr("Enter")
            }
        }

    }

}

}

/##^##
Designer {
D{i:0;height:436;width:640}
}
##^##/

but the result is like :
I don't what is the wrong that the RowLayout width not change.

since your RowLayout is inside a ColumnLayout use Layout.fillWidth: true instead of width: parent.width

@raven-worx , I have tried to change the code, but not work.

I found adding the "Layout.minimumHeight" which can make it work
Like the following code:

Layout.minimumHeight: inforWindow.height - inforInput.height

@white
you can also plase a spacer item between the combobox and button items:

Item  { Layout.fillWidth: true }
