Program selling under LGPL

[vrsek]

Thank you for answer,
I'm sorry for my english.. so, to read LGPL licence isn't helpful for me, because it's so many words and sentences which I don't understand. Automatic translator isn't solution.
I know that a best way is contact the lawyer, but it's money... First I have to earn money.
I had in mind conditions headly like: Have I to say somewhere in the program 'It was in Qt developed' or Have I to give somewhere TXT file with LGPL licence??
I don't think so it's complicated. Some conditions are clear
1) Dynamic linked library
2) Public changes in Qt source code
3) ?

Lykurg, I don't know why I'm yesterday found nothing... Maybe wrong keywords for search... I'm yet reading other posts...
