Hi Muhammad
Good. As I said I tried to tr() everything that is relevant (thus, not trace or debug messages). If I missed some, then I would be happy to add them if you let me know where I missed. Otherwise if you can add the missing tr()s I would appreciate it.
I understand your preference to contribute to open source projects instead of commercial ones. Qtilities was only available under GPL before v1.4. I've added LGPL in v1.4, thus you can use it in your commercial project without having to pay me a cent, thus you benefit from countless hours I spent developing Qtilities. Also, the commercial license is available under an "any donation fee structure" for small companies (less than 5 people), thus you can pay 1$ and you can benefit from Qtilities. That's good enough reason for me to consider it as a good open source candidate to contribute to, but that's just my opinion.
That said, if you want to contribute I would off course appreciate it.
Cheers,
Jaco
