Topic: How the license qt works?

Greetings, the world! Decided to master qt for  planned in the far future to sale . And at once there was a question about licenses: subtracted on Internet open spaces that I cannot in the beginning  develop the software, and then at a stage of readiness and before the beginning of sales to buy the license. How they of lines-poderi trace it? Also write that if all the same it happened - it is necessary to call fairly and  before license purchase with all that it implies. They conduct any register of the compiled source codes, demand that I swore, tooth gave or how it generally works? As though fairly here I ask - how to swindle to spare?

And you are assured that you need to buy the license? There is a free license on Qt not superimposing on you of especially burdensome restrictions, or it is necessary for you any special addon libraries from command Qt?

How they of lines-poderi trace it? It they had such idea, still earlier before their Nokija bought. And I suppose that it was legally insignificant. It is possible to Tell everything, language, it without bones. P> also write that if all the same it happened - it is necessary to call fairly and  before license purchase with all that it implies.

Now most part Qt is distributed under license LGPL, and it quite approaches for commercial development. You lose support, but it to you hardly and is necessary, obliged  with Qt dynamic (but anybody to you does not forbid to bring them DLL with the distribution kit), and obliged to give access to the buyers to source codes Qt (and links on Qt' a site like as insufficiently). Some parts Qt go under the separate license, it is necessary to watch closely.
