ToolButton of QtQuick control 2 cannot resize icons

[tham]

I want to resize the svg icon to 80*80, but the contentItem of Toolbar always show me original size of the icon. How could I resize the icon of the ToolBar?Thanks

import QtQuick 2.6
import QtQuick.Controls 2.0

ApplicationWindow {
    id: window
    width: 360
    height: 520
    visible: true
    title: "Qt Quick Controls 2"

    header: ToolBar {
        Material.foreground: "white"

        RowLayout {
            spacing: 20
            anchors.fill: parent

            ToolButton {
                width: 80
                height: width
                contentItem: Image{
                    fillMode: Image.PreserveAspectFit
                    horizontalAlignment: Image.AlignHCenter
                    verticalAlignment: Image.AlignVCenter
                    source: "qrc:/icons/menu-icon.svg"
                    width:80
                    height:80
                }                
            }
        }
    }
}

Hi,

Have your tester with an Image in a Rectangle ?

Rectangle{
    width: 80
    height: 80
    ....
    Image {
         anchors.fill : parent
         ....
    }
}

use sourceSize property in Image :

sourceSize.width: 80
sourceSize.height: 80

like this code :

contentItem: Image{
     fillMode: Image.PreserveAspectFit
     horizontalAlignment: Image.AlignHCenter
     verticalAlignment: Image.AlignVCenter
     source: "qrc:/icons/menu-icon.svg"
     sourceSize.width:80
     sourceSize.height:80
}
