[SOLVED] Is there a solution to make proprietary apps with Qt without paying ?
I am a freelancer developper and a big part of my work is made using Qt. So i want to use Qt for commercial purposes. So is there a solution to make proprietary apps with Qt whithout paying nothing and without distributing the source code ?
If i must pay something, have you an idea of how much is the starter pack ?
Yes, from version 4.5.2 on, Qt is released under LGPL, so you can make proprietary apps with Qt without paying.
Thank you but i need to use Qt Quick.
Any idea ?
Qt Quick is part of Qt

But i think with the last versions of Qt, in which Qt Quick is available, you must ditribute the source code with the app. Is my understanding true ?

WIth this, you must provide the source code of your app.
Qt versions 4.5.2 and later (including Qt 5.1) are also available under the LGPL license. With this, you can create dynamically-linked proprietary apps without paying. If you modify Qt itself, then you must provide the code for your modifications. However, you don't need to provide the code for your own dynamically-linked apps.
