KDE-Forum.org

Hello,
This is my first post in this forum and I have first of all one confession to make:

I’m normally not a KDE programmer *runs and hides*

I do *use* KDE on my free time and I do appreciate the project very much tough. Also, I’m a very warm supporter of any open source project.

That said, to my issue:

In my professional life I’m a SW developer using Qt as the middleware for one of our companies applications. Quite recently Qt4 was released, and some features seemed to me as really nice. So I quite happily started to port our application (originally written for Qt 2.3.0. and already once ported to Qt 3).

Wheeeoo – bad move

MAJOR PROBS!

I’ve been porting the application for several weeks now, and I still don’t see any light at the end of the tunnel (yet it’s only 200k lines of code).

Ermm, some people might probably call my code is a little “dirty” – I prefer to say that I use all the features available, to expand Qt so that it could be used for an abstract modelling similar to dataflow diagrams used in MatLab/Simulink. Most of the application is in fact is this extension to the Qt middleware.

I used the QObject meta data quite a lot, threading and overloading of undocumented functions I dug up from the Qt source e.t.a.

OK – I admit it, I was begging for trouble. However, I’m willing to pay a certain price for Trolltechs change of API, but I think what they’ve done is simply too much. (Even the clean and simple classes are changed – like containers and such). So now dear fellow KDE developers, my question: have you made any reflections about Qt4 yet? Will the KDE sourcebase be ported to Qt4? When will this be done and what are your experiences and reflections so far?

I know that I might be stretching this community’s willingness to help me out a bit, but any information would be truly appreciated and helpful. I would not hesitate to rewrite the application from scratch if I got convinced that it’s worth it. In case some one wonders about why I addressed this issue here instead of turning to Trolltech, is because I fear that their responses might be a little biased.

Keep up the good work! We’ll soon get Bill Gates on his knees, begging to join us
