Qt non commercial for Windows version 3.0


Message 1 in thread

Hi,

Is the 3.0 Qt version planned to be available as non commercial for Windows ?
In the trolltech internet page, I can only get the 2.3 version.

TIA,

Stephane

No.  Not at this moment.   Have you considered
wxWindows?  Not as polished as Qt, but its free for
all platforms.

Or how about just Qt 2.3 non commercial (let's try and sell the subject of
this mailing list... :-) ) That in itself has got far and above the
features one would expect in a GUI toolkit. I'm using it for a
free-software project of my own, anyway...

I was actually pleased to see this "provocation", because I hoped it might 
bring out a troll that could tell us when we can expect a 3.0.x non-
commercial version to be released.

I've had a fair amount of luck taking new things in QT3 out of the 
open-source X11 QT3 distrubution and backporting them to run on QT2, since 
most of the system specifics are already abstracted by the time you get to 
the higher levels.  Specifically, I yanked QHttp out of QT3 and have it 
running smoothly on top of QT2 on both linux and Win32.  Thought about doing 
this with QRegExp as well, but haven't tried it yet.

Hi,

are you allowed to do that  ( regarding the Qt license ) ?

The code backported from the X11 free edition would be under the GPL,
thus forcing every application using them to be under the GPL (or a
license granting the same freedom), too. The non commercial license is
not compatible with the GPL, so you can actually not do/release anything
with the backport (as an application linking against the non commercial
edition can't be GPL'ed) although the backport itself doesn't violate
any license.

Actually one can create a GPLed program with non-commercial, but needs to
grant linking with nc .dll without distributing the nc source (which, of
course, we poor free software developers don't have :o) )

The problem with backporting is exactly that, we can't change the license
from the x11 edition to include that permission as we are not copyright
holders ;)
Of course, if you port the whole thing, then no license changes would be
required.

OK, this is sounding familiar.  I thought I remembered some discussions on 
incompatibilities in the NCE.  I don't think this would preclude me from 
distributing my application in source form since it is perfectly legal to 
compile and link it agains the X11 version of QT, and an individual would be 
within their rights to make a personal Win32 compile but not distribute it.  
The other alternative (assuming Trolltech doesn't release a NCE QT3 some time 
soon) is to write my own QHttp and avoid the whole issue completely.

I haven't given it too much thought, but as I understand it, the X11 
free releases are under the GPL, which means I am free to do whatever I want 
with the source code as long as I distribute my modifications in source form. 
 I know there are some issues with the Win32 NCE license not being compatible 
with the GPL, so there may be some conflicts there (please enlighten me if 
there are), but I haven't worried about it too much since the code in 
question is a custom app written for use by my Dad, so it's not in general 
distribution at the moment.  If I decide to release it on the web I'll have 
to worry about that a bit more though.
