Use bindable QProperty in Qt QML classes

XMLWordPrintable

      We have QProperty in in qtbase, and the QML engine already has support for it. However, all the classes that we currently expose still use the old property implementation. For Qt 6, we want to introduce QProperty at least in some places:

      • to validate the design and test the implementation of QProperty and
      • to improve the performance of QML
