[Ktechlab-devel] Kde4

[Vincent Nikkelen]

Hi,

Julian Bäume has been working on a QT4 port. His work is available here:
http://krtek.asta.uni-luebeck.de:8080/repos/KTechLab/

This probably is a better starting point then beginning from scratch.

Groetjes,
Vincent

I am also in the ML ;-) It might be easier to contact me this way.
I found this guide to help porting to kde4:
http://techbase.kde.org/Development/Tutorials/KDE4_Porting_Guide
I'll read it to see if it can be of any help.
