Hi Ralf, Many thank's for your answer. I have noticed problem with row colors. I understand that TreeEditor is bad idea for RAP.
Many thank's for your feedback. Regards Angelo 2012/8/20 Ralf Sternberg <[email protected]> > Hi Angelo, > > It's great that this simple approach works out of the box in your RAP > application.
