dynamic margin according to wrapped text

[OPit44]

Hi ,
is there a way to dynamically change margins of a Label when the text is wrapped or not ?
I try this one but it doesn't work :

Button {
    id: root
    width: 146
    height: 60
   
  background: Rectangle {
        id: buttonBackground
        anchors.fill: parent
        color: "#333"
        border.width: 0
        radius: height / 2
    }

   contentItem: Label {
        text: root.text
        font: root.font
        anchors.fill: parent
        anchors.leftMargin: contentWidth > width ? 12 : 4
        anchors.rightMargin:  contentWidth > width ? 12 : 4
        horizontalAlignment: Text.AlignHCenter
        verticalAlignment: Text.AlignVCenter
        wrapMode: Label.Wrap
        elide: Text.ElideRight
        color: CustomColor.hightlightedText
    }

Any idea ?
Thanks

How does that code work on your end?
It seems to work fine...
What do you want actually?

contentWidth > width not working, it's always 4

Try using lineCount > 1 if you want to check whether the text is wrapped.

Yes great, thank you.
I add another thing which is to take into consideration the number of lines once the component is completed, because if I manage the margin directly during initialization, it does not work:

anchors.leftMargin: contentWidth > width ? 12 : 4
anchors.rightMargin: contentWidth > width ? 12 : 4

...
Component.onCompleted: {
            anchors.leftMargin = (lineCount > 1 ? 12 : 4)
            anchors.rightMargin = (lineCount > 1 ? 12 : 4)
        }
