When you select "Open source distribution under a LGPL or GPL license", the Qt website replies "Are you prepared to make your application source code publicly available?"
Well, this is not actually true.
The LGPL license allows dynamic linking of proprietary code to LGPL libraries as long as the recipient is allowed to link the (proprietary) object code to a different version of the library.
Therefore, it is sufficient that the end-user receives the object code and the proper information for relinking.
Please, fix this misleading message!
