Don't emit valueChanged signal at the initial binding evaluation

XMLWordPrintable

      Code

      import QtQuick

Window {
    id: root
    width: 640
    height: 480
    visible: true

    property int constVal: 100
    property int boundVal: true ? 100 : 100

    onConstValChanged: console.log("constValChanged:", root.constVal)
    onBoundValChanged: console.log("boundValChanged:", root.boundVal)
}

       

      Outcomes on Qt 6.8.1
      When the app starts up...

      • ...we see "boundValChanged: 100"
      • ...we don't see ""constValChanged"

       

      Suggestion
      Both constVal and boundVal should behave the same, from the point of view of valueChanged signals
