Set attached property in function

krobinson

In QML is it possible to set an attached property from a function? For example Layout.maximumHeight. If I have a function.

function setMaxHeight()
{
    //Can I set Layout.maximumHeight on a component here?
}

@krobinson Hi! That's easy:

import QtQuick 2.3
import QtQuick.Window 2.2
import QtQuick.Layouts 1.2
import QtQuick.Controls 1.4

Window {
    visible: true
    width: 600
    height: 400
    color: "gray"

    function myFunction(x) {
        myItem.Layout.preferredWidth = x
    }

    RowLayout {
        anchors.fill: parent
        Rectangle {
            color: 'orange'
            Layout.fillWidth: true
            Layout.fillHeight: true
            Layout.minimumWidth: 50
        }
        Rectangle {
            id: myItem
            color: 'plum'
            Layout.fillWidth: true
            Layout.fillHeight: true
            Layout.minimumWidth: 50
        }
    }

    Row {
        Button {
            text: "Click me!"
            onClicked: myFunction(300)
        }
        Button {
            text: "Close"
            onClicked: Qt.quit()
        }
    }
}

Thanks, I swear I tried that. That's nice and easy.
