Trolltech Releases Qt 4.0
lypanov writes "Trolltech has released Qt 4.0 both under commercial and GPL licenses for X11, Mac OS X and MS Windows. It is the first time that a MS Windows GPL edition is available. To celebrate the release Trolltech employees have created a song and a music video (Bittorrent download, Ogg Theora version). Read the Qt 4 Overview and the online Qt Reference Documentation for more information. You can download Qt from ftp.trolltech.com or from one of its mirrors. Work on KDE 4 has already started with making a development branch of KDE compile and run with Qt 4."
I just had two stories disappear on me... one about amazon patenting user/browser histories and some other goof-off story..
Will the KDE library be available for windows now?
I didn't know trolls could sing and dance. :)
Where does the name TrollTech come from?

Trolltech sounds so...dubious. I mean, when I think of Trolltech, I think of spyware. Hell, anything that is profession with the name "Troll" rubs me the wrong way.
I can imagine their future... "The current stock value of Trolltech rose to 300 dollars a share..."
Life is not for the lazy.
I've worked with my fair share of windowing APIs and QT's OO approach to the problem is very well done. On the one extreme we have the heavy MFC which has grown out of control into a mammoth mess. wxwindows, pretty much a clone of MFC, shares the same issues as MFC. WTL seems hopeful, if only anyone was using it and it had any sort of support.
The Win32 and Gnome APIs are written in C, so though they are fast, they doesn't get any of the programming benefits of Object Orientation.
Thought it has a funny macro kludges in certain places, the QT API is absolutely a joy to work with.
Its a troll.
Buh Duh Dum

I agree. QT is good and liked by all the developers I know who work with it. It is expensive to use commercially, though. For a developer's license that includes integration with OpenGL and other things we need, it runs $4950 USD.
Have you used Qt before? Their APIs and particularly the way that they handle event-driven programming (signals/slots) is very well done.

1) QT doesn't suck
2) QT is GPL'd, not LGPL'd, so whoever wishes to use it in closed-source software must buy a license to do so. This means TrolTech can afford to continue developing it full time, while still getting it well-used in open-source projects.
3) The commercial license is very affordable.
4) QT is very cross-platform.
5) QT is very full featured, but still fast and light.
6) QT includes a very nice GUI designer.
I'm sorry, I could see how having their BSD/Linux versions open and their windows versions closed could keep them in business; but now that they don't have any income generating platforms left, aren't they going to be out of business next week?
If not, how not? I'm very curious.
These are not really alternatives. Gnome is a bloated non-portable piece of amateur work. Java is bloated, portable, requires JVM and slow as hell. wxwindows .. well, not many people are using it anyway, so it's not much of an alternative.
I downloaded the movie via BitTorrent, but it does not seem to work. Is this encoded in some funky format?
I have to admit, this is one of my favorite trolls.

"Work on KDE 4 has already started with making a development branch of KDE compile and run with Qt 4."
Oh, uhm... would not time be better spent at kde.org fixing the many bugs in KDE 3? I still have to strip out kicker (the panel) and kdesktop (the desktop candy) and replace them with other less known programs just to get a semi-decent x-windows running - and this is not a trivial task. There are still many bad bugs in just about every KDE 3 program out. My personal opinion is that KDE focuses on gee-whiz-bang-cool features rather than stability and reliability of the basic necessities needed.
Sounds more like Pommesbudentechno...
So they could kill GNOME.
:-)
Hmm... I never thought of it, but I wonder if the inverse is true. Gnome was created in response to the Qt licensing, no? Perhaps it was the GNOME guys who wanted to play a little naming fun with the Trolltech guys.
Either way, it adds a bit of fun depth to the (constructive) competition between Gnome and KDE.
I love KDE 3.4.1, and from what I have read KDE 4.0 will be even better than all the Windows versions ever released put together. Thank you Trolltech, QT4 and KDE 4 will soon make my life and the life of every other Linux (ab)user out there so much better.
9/11: Never forget it was a false-flag operation
Haavard and Eirik Eng were thinking about what to call the company for a while. One night,Haavard had a dream where the company was called "Trolltech". In the dream his wife hated the name, so he asked her what she thought when he woke up. She liked it. The rest is history.
As to being referred to as "Trolls", we don't mind. Trolls are something very Scandinavian, and in a way provides a title for all of us to share. It's kind of a bonding thing.
trolls are *large* and gnomes are *small*.

I consider a huge ego a prerequisite to being cool. It's a warlord thing, so lesser beings might not understand.
As for attempting world domination, that just comes along with the super powers. You get some free time, you get that old itch to conquer, and one thing leads to another.

i see the free version is for vc++ or mingw on win32.
the old version that cam with the Qt gui book was vc++ or borland 55, no gnu.
what is the difference between mingw and a cygwin installed gcc/g++ environment ?
tia.
would be a story about how KDE can be cross-compiled on linux to run on wine or natively on windows.
at present, the only way to compile KDE for windows is by compiling it under windows (which requires that you have windows).
and that means you have to utilise a specialised forked version of kde source code, which has a bastardised version of configure, called configure.bat.
yerk.
does this mean inputting accents on qt applications will finally be fixed? kde and lyx have been unusable for me since qt-3.something...
I might be just an ignorant troll, but if it wasn't qt-3, I don't know why else i can't write accented words on anything using qt.
$50 for DarkBasic is "very affordable".
$109 for Microsoft Visual C++ is "quite affordable".
$3300 for QT 4.0 Desktop is not "very affordable".
And that is just for one platform. If you want to use one of Qt's biggest strengths ("QT is very cross-platform.") you have to shell out $6600 to be able to compile for all three platforms.
Depending on the economics of your business, it may be worth the money, but "very affordable" it ain't.

With free alternatives like gnome, java and wxwindows
How is QT *not* free?
THey just finished saying that their code is running on several platforms (for non comercial use) for free.
I'm not a prophet or a stone-age man,
I'm just a mortal with potential of a super man.
Excellent comments. May I add another few:
7. All versions (commercial included) come with source. This proves very handy when sub-classing widgets.
8. Qt has the only C++ string class worth using, QString. Who couldn't love
str = str.stripWhiteSpace();
9. Regex support!
Also, it's Qt, not QT.
Does this come with a native Win compiler or do you have to use the framework as a plugin with MS Visual Studio/C++?

What does a month of dev salary + new machine cost.
Its affordable in regards to cost to an IT shop, not hobby programmer. Think more in terms of comparrison to MS Office or full versions of Adobe suite for price comparrisons.
And for the hobby programmer there is Qt (or GTK if you prefer)
If you don't make enough money from your commercial software business to afford a one-time expense of $2000 (the light version includes everything you need in a toolkit), you have no business writing commercial software. I mean, that's only about two weeks of one developer's salary. You'll spend about 5 times that in lost productivity if you use VC++ alone. The $3000 version includes XML, databases, networking, and a ton of other stuff which is definitely worth it if you need it. Not to mention you get full source code.
Troll indeed.. Let's see.. you're comparing a cross platform GUI toolkit against:
1) A toy programming language
2) A C++ compiler and IDE
That's not apples-and-oranges. Those aren't even fruit!
The legal jargon surrounding the use of scripting languages and Qt is still kind of vague. Buried very deep in their FAQ section is the question Can I develop commercial applications with PerlQt or PyQt or other Qt wrappers? which isn't that helpful.
It still doesn't discuss in-house applications that are meant to solve production needs, but will never be sold or given away because the code is: too customized, reflects a particular business model, and/or not well polished. Perl/Qt is so much better than Perl/Tk, but we tolerate Tk because it's free.
Now I don't object to the core developer of applications needing a license, since that is what corporations do with Visual Studio, but scripted languages is kind of fuzzy. I think the best way to solve this is to officially support some of the language wrappers, like Perl and Python and provide some mechanism that determines an elegant way to "lock the interface layout" unless a developer license can be had. For example, only precompiled QtDesigner User Interface files could be added run-time, or something like that.
Then distribute it with ActiveState's ActivePerl or ActivePython. That version would only allow GPLed applications to be built, maybe through a variable like $main::LICENSE="GPL" to be declared, or something like that. You would have to purchase ActivePerl Pro Studio in order to develop commercial applications with the Qt widget set, but again the same "lock it down without a license" could be had.
Official support for scripted languages is the only way to sort out the need for quick, small programs for which C++ is inappropriate.
AFAIK some people is interested in getting a native windows version of KDE (not the cygwin crap) out with KDE 4.0.
I guess that has been one of the major reasons to extend the GPL licensing for the QT-windows-version. Really, there's a lack of decent freeware software in windows (advertising/spyware-free, etc), most of the decent software in windows is comercial.
A windows version of all KDE apps means lots of people will use those apps, and unlike most of the 3rd party software, KDE software is (and feels) more "integrated" (same UI instead of one UI for every program, etc). If the windows version of KDE is succesful lots of people will want to use QT for their commercial apps, I guess.
$2500 for Rational Rose (sorry, no link), and that draws pretty pictures.
(Okay, so it does a lot more than draw pretty pictures, but I would make the argument that if you were doing x-platform development Qt could be a lot more beneficial to you than Rose.)
- serious "get laid" development - some class dancing at least comes with SHAME TECHNOLOGY(tm) in all plataforms!

wxWidgets wxString has this:

str.Trim().Trim(false);
> 9. Regex support!
wxWidgets got ya covered here too, baby! See wxRegEx.
Have you ever used KDE?
wxWidgets: Qt: Notice that Qt manages to do it in a sane fashion, with a single, readable method call. wxWidgets requires two calls, one with a boolean parameter? This leads me to number 10: Sane and readable APIs.
On this page: http://www.trolltech.com/download/opensource.html it says
Can I use the Open Source Edition to write commercial software?
Only if you plan to publish the software exclusively under the GPL.
If you plan to release a commercial product either using closed source or a mix of closed and open source licensing, you must use the commercially licensed version of Qt.
As I understand it, the GPL gives me the right to incorporate Qt into a commercial (and GPL'ed) product and they can't tell me otherwise since Qt is distributed under the GPL. Am I wrong? Does TrollTech have the right to tell me I can't make a commercial GPL product with Qt?
Do not click on the link in parent! This is a troll which makes your browser go nuts.
I think that I will stick with GTK+.
Have you ever used a Qt program on a light desktop environment?
Qt is ok (not exactly light), it's KDE that sucks for being bloated as hell.
Same goes for GTK and Gnome.
If you followed the link to Trolltech you would'nt have to ask.
As the filename ends ".mov" you could have it deduced yourself.
If you need encoding details: H.264/ AAC (=Quicktime 7)
Just because it's about Trolltech, you don't have to be a troll and call H.264 a "funky" format!
If you're after something that is a cross platform GUI toolkit, non commerical / commerical with LPGL license might i suggest Wxwidgets.
http://www.wxwidgets.org/
I have been using wx for a few months and love it.
Cross platform (Win32, MacOSX, Linux).
Very mature (12 years old) platform filled with lots of classes for most things you could think of.
And the seller point, no need to give away your source if you want to write something commercially at zero cost.
This doesnt mean QT isn't any good, but Wx has been around longer and really fills a need - try it out!
I'm using a Windows development platform Dev-C++ with all the hooks of wx: http://wxdsgn.sourceforge.net/
Wow, I always thought it was Q-T pronounced like cutie, but in the video they say it like 'cute'.
I've been so wrong all these years, oh what else have I been wrong about?!
I just went through this whole song and dance of deciding which toolkit to use. I wanted to use Qt because I perceive it as more established than many alternatives. But the reality is that they do not support many platforms. Sure, the desktop platforms are supported. But in this day and age, everything interesting is happening in the embedded world. So wheres the support for Pocket PC, Palm, and all the smart phones? Sucks, but at least I realized it now, when I've only invested $39 in Qt rather than the full $6K... lol.
Have you ever used KDE 3.X?
From here:
Haavard Nord, Trolltech's CEO, and Eirik Eng, Trolltech's President, had been working together with various cross-platform GUI tools back in 1991. We were both very disappointed in their quality and were sure we could do it much better. Haavard went on to write his Masters thesis on GUI design, while I wrote a C++ GUI toolkit for a Norwegian company. In 1993 he called me up and suggested that we should join forces and use our experience in GUI design to write the toolkit that would be the king of toolkits. We had no customers, no funding and a lot of enthusiasm. Luckily we were both married to wives who had full-time jobs. We used some savings to rent a small office and hacked away for a year while our wives fed and cared for us.
Personally, I find the entire thing rather neat and almost romantic. If you told your spouse/sig. other "I'm gonna go work on something and make absolutely no money for a year and you're going to support me...do you mind?" (s)he'd probably say something along the lines of "hell no" or go packing. The company name comes from a dream one of the cofounders had about their wife as well.
I dunno. I don't see that many couples that're close or stable enough to do that.
There's more important things "chicks" can have than a "hot" body. Like...helping you realize your dreams?
-- Political fascism requires a Fuhrer.
From the /. summary:
I think what was meant here was proprietary licenses, not commercial licenses. This is a rather common misunderstanding that stems from not seeing the GNU GPL as a license under which one may do commercial work. But many developers and distributors have done commercial activity involving GPL-covered works over the years. What the GPL prohibits is distribution of proprietary derivatives, hence the GPL is not a proprietary software license.

If you think about it, $5000 is pretty cheap -- that's ony the cost of about a month and a half or so of a developer's labour; a good tool can easily increase productivity enough to regain that month and a half in additional productivity.
"There's more important things "chicks" can have than a "hot" body. Like...helping you realize your dreams?"
:P
But I'm shallow..You Insensitive Clod!
Just because you have dreams and aspirations doesn't mean we all do, some of us just want a "hot bodied chick!"

Trolltech is just too kind:
c at_id=4
http://www.qtopia.net/modules/xoopsfaq/index.php?
Gtk: Although Gtk is on Windows as well as X, Qt has a far better cross platform implementation. Qt is written in C++, instead of C, has a company standing behind it, and needs much less code to write the same app.
How about mentioning GTK is about as stable as a one-legged table during a 9.0 earthquake?
GTK apps get a NULL pointer exception and abort exceedingly often. What point is exception handling if you just abort? Might as well just deref the NULL pointer and segfault - at least one can use a debugger. And it doesn't appear GTK programs try to save state or even clean up after themselves when they exception abort.
KDE only crashes on me when Xorg kills my computer or Linux's wonderful memory management causes an out of memory error and kernel killing spree - so when Firefox memory leaks - KDE pieces and various daemons get killed too - can't blame Qt or KDE for that.
Also, doesn't Gtk shoehorn C++ like features into C, making for a God awful mess? The disadvantages of C++ without the advantages. Everyone has a C++ compiler available - g++ is free and on all platforms (well at least those supported by gcc - which is anything you'd care about).
Gnome needs to just stop competing against KDE and allow their work to be folded into KDE.
Gnome said it was about the licensing, and that has been resolved for how long now? How many years?
Linux needs a standard desktop - user's don't want to be forced to choose - app writers don't want to have to choose and no matter what - lose some customers - and Gnome is bleeding away resources that could go to KDE.
Just because it CAN be done, doesn't mean it should!
Can somone please help me out how to install qt on windows? (Yes, this version, not the cyg-win version).
I got it extracted to c:\qt\4.0.0 but running configure.exe does not do anything. It just makes me accept the license and tehn nothing. I tried the configure option "-qmake" which didnt do anything either...
Ermmm... I am lost.
that that Eurovision Song Contest has far too much influence!!!11!
Yes, but you haven't.
I've come for the woman, and your head.
With full MVC support, Qt is finally on par with Gtk and Swing in my book. Only it's better!
Depending on the economics of your business, it may be worth the money, but "very affordable" it ain't.
If you think $6600 to allow for the productive development of software on all three major platforms, simultaneously, is EXPENSIVE, you are lacking in experience.
$6600 is a midline wage for a single coder for one month. Any decent sized project goes on for YEARS, and usually involves at least 2-3 coders.
$6600 is a drop in the bucket if it saves even 5% of developer costs over the long haul! A single sale can pay WAY MORE than $6600 when you are talking about custom, vertical apps, and that sale might well be made on the back of "*nix/Mac/Win compatable"...
Cross-Platform is a selling feature again!
I have no problem with your religion until you decide it's reason to deprive others of the truth.

"The way we can tell it's C# instead of Haskell is because it's nine lines instead of two." -- wadler
Well, it certainly doesn't comply with the Open Source Definition. "No Discrimination Against Fields of Endeavor" and all that. So the development tools themselves are certainly not "free".
Why would I get modded down for posting a warning?
I think you're viewing this from the point of an individual. For a large company, that is one months salary for their lowest employee. Won't take long for a decent product to pay itself off at that price.
THey just finished saying that their code is running on several platforms (for non comercial use) for free.
Well you hit the nail on the head there; they tend to chop and change. One moment it's GPLd then the next moment it's only free for non-commercial use (a restriction that's incompatible with the GPL).
Sometimes they even claim that private non-distributed development requires a "commercial" license. That obviously doesn't fly with the GPL terms but still, the threat of court action if you don't comply with bogus requirements is enough to make it less-than-free IMHO.
"a restriction that's incompatible with the GPL"
How is saying that you can use this as long as your code is distributed under the GPL for free, against the terms of the GPL? Maybe against the terms of a BSD lic. but not the GPL.
If you want to keep your code closed, then pay or use a different toolset. If you are going to profit and not give anything back, then why should trolltech give you anything? Sounds hypocritical to me.
If you do private non-distributed development and they want to require a "commercial" license call is beta code. Who is going to know if it isn't distributed?
Now that I have defeated your complaint, QT will be release under a GPL lic. on Windows. --RTFA
I guess you also hate MySQL and hundreds of other open source projects that dual license their code.
There's more important things "chicks" can have than a "hot" body. Like...helping you realize your dreams?
What if my dream includes chicks with hot bodies?
It's The Golden Rule: "He who has the gold makes the rules."
They've released a song?! Don't they remember the dancing bits of Hitachi and how unbelivably mindblowingly cheesy that was?
*shudders*
Because requiring you to distribute under the GPL for free is adding an additional restriction to the GPL, which is prohibited.
The point is, you can sell GPLed code.
And their licience doesn't contain any exceptions to the GPL (which they would be able to make seeing as they are the authors... but no one could then release under the GPL...) so you can sell things you make under the full version.
1) QT doesn't suck
Is it really that much better than wxWidgets? I can't find it right now, but somewhere on the wxWidgets website there is a comparison presenting some basic GUI functionality in Qt, MVC and wxWidgets, and the wx code is by far the shortest and most readable.
The point is that Trolltech --READ THE FUCKING PRESS RELEASE-- is releasing the QT under the GPL. ++PLUS a closed source license for those that want it++
Are you just stupid or are you retarded?
> $6600 is a midline wage for a single coder for one month. Any decent sized project goes on for YEARS, and usually involves at least 2-3 coders. $6600 is a drop in the bucket...
You're forgetting that the licensing is per developer. If it's hard to understand, just imaging not receiving a paycheck for one month. Now go and rethink your post.
The problem with Qt is that you cannot buy floating license.
.rc with C++ code.
Rational Rose for instead you can buy 1 or 2 floating license for 50 software engineers.
One of the problem in the current market is called:
"Free" MSDN Universal DVD license
Hire a developper or a MSCE, is the same thing,
except you get free licenses per MCSE.
Maybe we need a QTCE group license?!
Ask your boss to buy more Rational Rose license... please use Visio XP.
Ask your boss to buy some Qt license... please use Microsoft Visual Studio.NET
Why?
Boss: "Stop wasting public funds will ya!"
Seriously 6600$ is lots of money,
just multiply this by 50-100 employees
and you get a whopping 330,000-660,000$ US!
That's like asking your boss, please buy half M$ of Qt license.
There's no "cheap company wide" licensing.
A volume price of 660$ per seat would be more reasonable.
As far as the RAD part of Qt, anyone who used VCL/C++ Builder or Visual Basic will tell you
how much it sucks.
RAD Programming in Qt is as hard and tedious as Java, if not more.
One problem with Qt is that automatic code generation is insufficient.
Want to design right-click menu... please write C++ code.
Want to design a KApp... please write a
Want a standard menu... the default one is incompatible with KDE and no default KAction.
Qt and KDE needs to work closer together, because currently the integration just sucks.
The other problem with Qt is that you buy a library without a built-in IDE and multi-platform debugger.
At least, if it provided a Visual Studio debugger equivalent. Don't get me started on extremely painful gdb or ddd.
Qt Designer is NOT an IDE.
KDevelop sucks -> not user-friendly and no debugger.
It might be less painful than GTK or WxWindows, but it still far from useable than VCL.
Huh, lack of decent freeware software? You are kidding right? There is a ton of decent freeware software (some is advertising supported, and some not).
. You are talking anywhere from 3000 to 5500 USD. Those people doing shareware or freeware, and who DO NOT want to give out the sources will not invest that kind of money for an SDK. You still will most likely need to buy an IDE, and compiler. And the moment you purchase Visual Studio you don't need a GUI toolkit.
I use Linux, OSX, and Windows, and if one thing can be said Windows has momentum BECAUSE it has all types of software freeware, and commercialware.
Developers on Windows will not use QT for their commercial apps. The main problem is the cost. http://www.trolltech.com/products/qt/pricing.html
The argument of cross-platform does not spin either because it means a 5500 USD investment, which has to pay off. If were doing cross-platform using C++ I would use either GTK, or wxWidget.
"You can't make a race horse of a pig"
"No," said Samuel, "but you can make very fast pig"
(Equally all Fields can buy a commercial/proprietary license if they like it better. But that does not claim to be free/open source any more.
I'm GNOME junkie, but KDE is quite superb desktop envorement (my taste is just different) and Trolltech are really doing good and professional job here. Desktop wars aside (we have nothing to fight each other about), I love lot of KDE apps like K3b, Kbabel, etc.

See comparison with Qt.
Ragarding Qt vs wxWidgets comparison, you may want to read this: http://freshmeat.net/articles/view/928/
To me, this seems like an interesting catalyst to learn a GUI API. Not only is cross platform is a welcome positive; the Qt structure is intriguing. Particularly see the Qt Object Model for a great read. I had little idea that Qt used a signals model and was tending towards strict use of the MVC paradigm. Perhaps comprehension of Qt would increase my chances of bothering to learn the almost entirely alien Cocoa/Obj-C rhetoric.
Actually, having downloaded Qt4 for Windows I've found that the GPL version doesn't "support" VC++. Only the makefiles for mingw are included. The configure "script" (which is actually an executable) just seems to display the GPL (which you can edit in an accompanying text file so you don't have to hit enter repeatedly), ask if you agree and then bail out. Perhaps that's because I don't have mingw installed; I'm not sure, because it didn't give any kind of error.
It's quite annoying that it doesn't come with the makefiles for VC++. I don't use the Visual Studio IDE, but I always use Microsoft's compiler (CL.EXE) and have a big collection of libraries already built for it which I don't fancy having to rebuild to switch compilers just to appease Qt. No doubt I could, if I had enough knowledge about Qt and the time to do it, create my own makefiles for CL based on the ones supplied for mingw, but that TrollTech didn't include them when they clearly have them for the commercial version is a little annoying. Why are they mandating which compiler open source developers must use? It's not like I'm suddenly going to plonk down a $4000 licence fee just because I want to use a different toolchain. What difference would it have made?
Standard C++ strings suffice, together with the boost string library, no need for a new string class when you can put all the new functionality in free functions.
#include <boost/algorithm/string/trim.hpp>
using boost::algorithm::trim_copy;
str = trim_copy(str);
There is no discrimination against fields of endeavour in the GPL, which is the Qt license. Furthermore, the GPL is clearly listed on the OSI website as an OSI-compliant license.

According to wikipedia, Halloween derives from Hallowe'en, an old contraction, still retained in Scotland, of "All Hallow's Eve," so called as it is the day before the Catholic All Saints holy day, which used to be called "All Hallows," derived from All Hallowed Souls.
In Ireland, the name was Hallow Eve and this name is still used by some older people. Halloween was formerly also sometimes called All Saints' Eve.
The holiday was a day of religious festivities in various northern European pagan traditions, until it was appropriated by Christian missionaries (along with Christmas and Easter, two other traditional northern European pagan holidays) and given a Christian reinterpretation.
Halloween is also known as the Day of the Dead, and it is a day of celebration for Wiccans and other modern pagan traditions, though the holiday has lost its religious connotations among the populace at large.
Halloween is also called Pooky Night in some parts of Ireland, presumably named after the pookah, a mischievous spirit.
Thanks, it was an interesting read. It seems very favorable for wxWidgets and maybe a little harsh on Qt: "If you're not an API purist, you can choose among the three huge toolkits, FOX, Qt, and wxWindows. I personally think Qt is made irrelevant by both of the others because they are not missing anything Qt offers."
I think one of the comments is worth noting. It says:
"Pretty good summary overall, although I feel compelled to point out a few things I've noticed about the toolkits and have heard from others:
- Qt is by most accounts the best designed, fullest featured, and fastest to work with C++ GUI toolkit out there.(...)"
Notice that the commenter honestly admits, that he's repeating things he heard from others. I have also many times heard that Qt is best designed, fullest featured etc (at a time I even used to repeat it myself, as something obvious). However, I haven't seen any actual facts to back up this statement, especially regarding the comparison with wxWidgets. So, I think -- maybe we all "know" that Qt is the best toolkit, simply because Trolltech PR guys made such statement printed so many times that everybody believed?
Clever signature text goes here.
I know based on having tried using GTK, Qt and Wx. Qt was the best. The rosegarden developer does a good piece on why it's better than gtkmm from the point of view of someone trying to actually write a program, though I haven't seen a similar thing for Wx.

What you don't understand is that this is how marriage works. My wife left a good job so I could make a career move. I supported her as she went through grad school and the process to become an Episcopal priest. Right now, she is at home with the kids while I am presenting at a conference.
We have been married 23 years, and I claim that this sort of thing is more typical than you might imagine. We have both realized dreams because of the support of the other.
$6600 is a drop in the bucket for any company that deserves to stay in business. Regardless, the ecomonic benefits of using Qt far outweigh the costs--a cross-platform development toolkit saves massive amounts of coding time, and time is money.

News about the Kettle Open Source project: on my blog
Using OpenGL for rendering is obviously a step up for QT, but one area that could well be a problem is text rendering. Big fan of OpenGL that I am, it has to be said it's not that great at rendering text. If you want fairly simple text, it's fine, but for high-speed, anti-aliased, Cleartype-smoothed fonts it's not easy.
On Windows at least, QT used the old GDI rendering code which can do arbitrary text rendering extremely well. Replicating the speed and functionality of that is not trivial in OpenGL. You can used texture-mapped fonts, which works quite well, but if your application requires lots of fonts, at lots of sizes, you may run out of texture space quite quickly. Also, replicating Cleartype smoothing (for LCDs) is practically impossible.
I looked through the release notes for QT 4 and it appears that they will render fonts in OpenGL as filled paths. I've tried that also, and it can be VERY slow, especially if you use very smooth glyphs when building the paths to render.
Anyone know how they can overcome these issues?

Just built it. Yea, it's more lightweight, but don't remove QT3 just yet. The new designer lacks the project manager, code editor, etc. All that's left is the.. designer. While yes, this is more lightweight, etc, the main reason for using Qt over Gtk2 at times was that Qt3 lets you create a working gui app, FAST. I mean, generating the functions for all the signals, etc. Qt4 does not do this anymore. I have no problem with generating all the stuff by hand, but isn't the whole point to "Code less, create more?"
The 3D widget is somewhat cool, though.
$2000 is two weeks salary... in the US!
And meta moderating to get rid of them doesn't seem to do any good. I keep having hope though and have been meta moderating for over 2 years. Eventually it might do some good or get me mod points but I don't have much hope in either.
Two roads diverged in a wood, and I - I took the one the bus load of girls just went down.
Dang. Maybe wxwindows it the way to go.
Ya .. I would agree that wxWidgets' API is not the prettiest thing in the world. But the advantages of wxWidgets far outweigh any disadvantage, IMHO.
You need to ask yourself this question. Why do you hate the Mac?
> 2) QT is GPL'd, not LGPL'd, so whoever wishes to use it in closed-source software must buy a license to do so. This means TrolTech can afford to continue developing it full time, while still getting it well-used in open-source projects.
That argument just doesn't stand. Linking to the QT API cannot be considered "derrived work". I ship an application that uses the Qt API but I do not distribute Qt. Qt is installed on the user's computer. If the user has both my application and Qt, then she can link those two to work together. Another application could also be Qt-API compatible and be under a BSD license.
Do I distribute Qt inside my commercial application? NO.
If the user has Qt then she has the right to use it whatever way she wants and link whatever application *she* wants to it.
Absurd licesing.
I get mod points all the time. Its sort of a feedback loop you get way over 50 karma + good meta mods and you get to mod a lot.
Let's not forget that he's also comparing this against the cheapest version of Visual Studio. I don't think that many serious developers are going to be using the Standard Edition. Last time I checked, Standard Edition had a crippled optimizer. Any serious developer is going to be using at least pro, which is around $500. The Enterprise Architect version, which is what we use where I work, seems to be around $1,200.
How is QT *not* free?
I cannot write a closed-source freeware application without paying Trolltech. In contrast, I do not have to give Bill Gates a single cent in order to be able to write software that uses the Win32 (or .NET) API. Now who's the evil one here?
You gotta hand it to them for picking an appropriate name for their product. :)
please dont tell me you STILL dont understand that Gtk+ is indeed object oriented (there are classes, inheretance, polymorphism).

They may, however, take offense at you implying that most women would leave a man because he wasn't making money.

Don't just make shit up. No, it's not taken from one particular license that I know of, and it's certainly not from the GPL; the GPL doesn't contain the words "field", "endeavor" or "endeavour", or any form of "discriminate."
Yeah, sorry, misremembered something. I thought that Qt had something with a "no commercial use" clause on it. As long as it's just GPL, that's alright.

It's a really interesting read.
That's nothing, Apple released Quicktime 4.0 long ago. ;)
I think what was meant here was proprietary licenses, not commercial licenses. This is a rather common misunderstanding that stems from not seeing the GNU GPL as a license under which one may do commercial work.
The reason the non-GPL license is referred to as "commercial" is that it is a commercial product, or, in layman's terms, "costs money to acquire".
It is the license itself that is commercial, not the applications you distribute with it.
I wouldn't say I don't understand how marriage works, nor would I say I do.
Success depends on a lot of factors, like duration of marriage thus far and culture. In my country (the US), about half of marriages end in divorce and thus one could say any other outcome is sadly "above average". I fully agree and embrace the ideal I put forth as the template for marriage (i.e. supporting one another for better or worse in all each other's aspirations) however, I was simply pointing out having a healthy relationship is actually atypical, both statistically and in my personal experiences thus far (but I'm only 23).
Also, there's a huge difference between "making a career move" to something like a priest and starting your own company in an unproven market with no income from your product for over a year. In the former, there is a good chance you'll get positive income at the end (therefore, more of a matter of willing to wait for income later). In the latter, it's very probable you'll make absolutely no money even after a few years.
I'm glad your experiences were positive, and though I think it is how marriage should work, we ought never to impose our ideals on reality. Instead, see it for how it is, for it is because of this descrepancy that dreams are possible.

It took advantage of opening a terminal (I didn't know a web page could do that, I filed a bug with apple). Sounds, picktures, infinite browsers.... a real pain under safari.
There also used to be some bizarre language in the license FAQ stating that you were not allowed to use the GPL Qt to develop a commercial app, and then buy commercial licenses once you were ready to distribute commercially. Basically, in their eyes, any code developed with GPL Qt is forever tainted and can't be used any way besides GPL.
Here's the link that says basically that.
Their motivation is pretty obvious: most startups fail, so they want to get cash from any company using Qt right away before they go belly-up. But that's more restrictive and viral than even the GPL, isn't it? With the regular GPL, nothing is stopping me from developing my prototype using GPL code, and then replacing the GPL bits with something non-GPL at the last minute before distribution.
I guess the difference is that they're the ones selling you the commercial license in the end, so they can make the terms of the commercial license whatever they want. I.e. they can say that you're in viloation of that license if you initially developed your code under GPL Qt.
You didn't read the license correctly.

You MAY NOT SWAP license in and out.
You buy an individual license PER DEVELOPPER.
"It is a per-developer license.
The license is assigned to an individual. It may be transferred,
but only every six months and within the same organization.

Not a bunch floating licenses for the entire company.
It's not like you are getting:
5 windows floating license
5 linux floating license
5 mac floating license
1 cross platform floating license
"My gut reaction is this would be suicide if they did that, so I find it very unlikely they did."
That's what they do and that's why I'm complaining.
They are saying that floating licenses
do not make sense for a library.
So, unless your organization builds software on a single platform, then you need 6600$ multiplatform license.
You're forgetting that the licensing is per developer. If it's hard to understand, just imaging not receiving a paycheck for one month. Now go and rethink your post.
That changes almost nothing. Remember the "years" part of my post. It's not atypical for such a programming framework to save much, much more than a month in a 2 year project, and then there's maintenance after the fact.
Sorry. If you think that $6600 is unreasonable, you are lacking in experience.
I have no problem with your religion until you decide it's reason to deprive others of the truth.

Loosing even one month's paycheck out of two years is enough for me. Besides, read the licensing scheme carefully. If you want support you'll pay on the annual basis. If you compare it to offerings from other companies, it won't sound that reasonable for you.
Sorry. If you think that $6600 is unreasonable, you are lacking in experience.
Hard to believe that a man with experience can say something ignorant like this.
You didn't read the license correctly.
You're right, I didn't read it at all. And from the link you gave me, neither did you. If you actually found the license on the site, link to it and we'll be able to settle this instead of speculate on what it does or does not say.
You MAY NOT SWAP license in and out.
You buy an individual license PER DEVELOPPER.
Reread what I wrote earlier. I didn't say switch the developers' licenses, I just said give everyone ONE licenses for his or her preferred platform and have them stick with it.
In other words, I'm not saying swap the license, I'm saying swap the code you're working on. As long as the license doesn't forbid compiling code written on a different platform under a different license, you would be more than able to do this.
That's what they do and that's why I'm complaining.
They are saying that floating licenses
do not make sense for a library.
So, unless your organization builds software on a single platform, then you need 6600$ multiplatform license.
No, you don't. You could have one dev working on a Windows version, one on a Mac version, and one on X. Single platform -- $3300 -- for each, but you can build on all three platforms.
You have yet to show me a page saying they forbid this in their license.
If you metamoderate all the time, why would they give you regular mod points? It's harder to get that thankless job done, and people who do it, you don't wanna lose them. When they stop metamoderating, then you sweeten the deal and give them mod points, so they keep at it, it's like free work. (But it's not really work when it's fun doing.) All in all, they say the system randomly assigns mod points, but if those in charge 'care' about the quality of moderation, they might cut a few corners that give the system more efficiency at the expense of fairness and decency to human beings (Especially if they don't know they are being treated unfairly. I'm not saying they are cutting corners, but it could be a possibility, ya never know.) What matters though, metamoderators, is that you/we should feel proud, because we are the ones who really carry the weight, who keep the system in check, and that's why we come here, it's our collective work. I said 'we, metamoderators' but I'm guilty of being lazy too, because lately I've been getting a lot of mod points, and I don't really meta-moderate much when get regular mod points. By the way, mandatory joke: Don't ask what slashdot can do for you, ask what you can do for slashdot! :)
Where exactly did you find that lame "definition" anyway?
Clever signature text goes here.
Way to be about seven years behind the times. The OSD is courtesy of the Open Source Initiative and serves as one of the best expositors of what "open" actually is. Before it was the OSD, it was the Debian Free Software Guidelines, governing what could and could not be included in the Debian main distribution.
Give it up already. Just because an organization defines something doesn't mean that they are correct, and can exclude everything else from the actual definition. They can exclude things from their licenses etc., but they can't redefine the English language!
