I wrote a wonderfully useful Qt 4.8.3 application, not my first, which I use in the laboratory work I do. I fully incorporated QtScript..it plays an important role in how I use the program, basically letting me expose core functionality to JavaScripts that I make to control the lab hardware in my own way. I understand and appreciate the QJSEngine in Qt5 has the speed, etc., enhancements of V8—but I feel like the switch was a little beta—unfinished even. I do understand from the Qt bug database that technical issues arose in trying to implement full JavaScript to Qt signals-slots. But, as an example, what about a smoother transition—such as the inclusion of the constructors that allow me to JavaScript new a QObject? The Qt 4.8.3 ‘Making Applications Scriptable’ was a masterpiece. Now, QtScript has evidently been tagged as obsolete and so I would have to rework a few things. Can we count on Qt for a stable an consistent API in the future?
