   Cross platform gui toolkit and licence
  Hello everybody!Please provide me with a little help. I want to develop an application that i will be selling, in at least two version. Sell it without source code, and sell it with source code. The problem that im facing is that i dont know any gui toolkit that let me do this. As i understand from gtk i have to give the source code with my app when im selling it. Qt is very nice but ... well, expensive.Can you guys tell me of a free or commercial (but not expensive) toolkit that let me sell my app as i stated on the top?Also the gui has to have support for opengl.Thanks alot[Edited by - guvidu on August 28, 2008 4:45:09 AM]
wxWidgets should do what you need.   ;  GTK is under the LGPL license.I don't understand why you should give your source code if you sell your application.You just have to give the source code of GTK if you modify GTK source code (a thing you will probably not have to do).   ;  i can also recommend wxwidgets, it is crossplatform, and just as easy to use as Java, i can clearly see that is in development for a long time:Paul;  I most centainly dont undestand the GPLSo if i make a program that uses gtk or wxwidget (dont make any modifications to them - only use the library to make interface) i can sell my software with and without the source code. all i have to do is give a link to gtk or wxwidget library/code?am i correct?Thanks   ;  GTK+ is released under GNU LGPL 2.1, LGPL is not GPL:Differences between LGPL and GPL;  Thanks alot for the help guys. I think im going to use wxWidget :)
