Execute JS code right after QML Application start

Question

I've got an ApplicationWindow in my QML-Application. I'd like to execute a bit of Javascript-code right after loading it but don't find a handler (like onLoaded) to do so.

How can I accomplish this?

The handler you're looking for is Component.onCompleted. Here's a simple example:

import QtQuick 2.2
import QtQuick.Controls 1.1

ApplicationWindow {
    visible: true
    width: 500
    height: 500

    Rectangle {
        id: rect
        anchors.fill: parent

        // First paint a red rectangle
        color: "red"
    }

    Component.onCompleted: {
        // Make it blue when we load
        rect.color = "blue"
    }
}
