@VRonin
Thanks. I'm about to post to https://forum.qt.io/category/5/qt-io-webservices, please feel free to redirect if you think it's wrong!

@special_eagle hi,

I personally believe, that QT's official website is purposely vague on that topic. I contacted the sales team multiple times on behalf of different companies and the answer I got was always an interpretation of:

"To be sure you, you better by a license"

Understandable, The Qt Company is a company after all.

However as long as you yourself are not a certified lawyer, I would suggest contacting one to handle the issue for you.

If you have to buy a license, the cost of the lawyer won't change much in your expenses. If you don't need a license, It's a minor cost to bear, but at least you can be legally sure.

Hi,

And in the case you can provide a clearer version of that documentation, please consider doing a contribution.

+1

Qt documentation is always my role model when writing documentation for my own stuff (libraries).

Hi! Various parts of the framework and the tools are available under GPL, LGPL, and proprietary license. See here and here.

I'll also introduce myself while I'm here. Hi, I'm Mike Perez. Hope to have fun here. Cheers!

@kshegunov thanks! I'll look at it a bit later today. I appreciate the assistance.

@sierdzio
Ok so it sounds worse than it might become. :)

Because we were not in the same building ;-)

@raven-worx
Ususally man simply does'nt know how to say "UX design" and invent synonims/euphemismes

Many of them get confused on what Qt is, and many think that we are using Qt even though it is actually intended for something called QML and not C++

You can redirect them to Qt's wikipedia page, where it's written:

Qt uses standard C++ with extensions including signals and slots that simplify handling of events, and this helps in development of both GUI and server applications which receive their own set of event information and should process them accordingly. Qt supports many compilers, including the GCC C++ compiler and the Visual Studio suite.

and continues on to explain what QML is:

Qt also provides Qt Quick, that includes a declarative scripting language called QML that allows using JavaScript to provide the logic. With Qt Quick, rapid application development for mobile devices became possible, although logic can be written with native code as well to achieve the best possible performance.

Should be that simple.

@A-K-G
Yes, certainly good to discuss here too, but to solve the problem the Development list is the place.

Qt3D isn't complete, and as you say the documentation isn't there yet unfortunately. And as said, I believe the bigger target is to have a higher abstraction level api to 3D. Right now it is too close to OpenGL, requiring some understanding of that too.

It really depends what you want to do. I'd add R, free software and as powerful as matlab, it intefaces with C/C++ brilliantly.

For libraries I'll also highlight Eigen, if you need to do linear algebra on your statistical models

Back in 2013, I stayed at http://www.hotel-friedrichshain-berlin.de/

It was a nice place, quite close to the venue (but back then it was held somewhere else ;-)), and the price was OK, considering that it is Berlin :)

Thanks for the ping @sierdzio

Hi @adam-e I notified our sales about this. No idea where the message has gone, renewals are usually really fast.

Hope it works out fast.

In the constructor the dialog is not even shown yet, so there's nothing to close.

Usually with dialogs you have a code like this:

SomeDialog dialog; dialog.exec(); //exec calls show() internally

so if you want to prevent it from showing you can do something like this:

SomeDialog dialog; if (dialog.isInitialized()) dialog.exec();

where isInitialized() would return true or false depending on what the constructor did.

@VRonin
thank you extremely much.

Hi!

why the hell so many packets has qt*

Well, Qt is one of the most popular, if not the most popular, cross-platform GUI framework. The whole K Desktop Environment, which BTW is also quite popular at least in Europe, is build upon it. KDE comes with many applications, like utilities and games. So all in all it's no wonder that Desktop Linux distributions provide a lot of packages that depend on our cute framework.

why everything with qt in its name takes ages to compile

Can't say much about specific applications, but building the Qt libraries themselves doesn't take ages. Just did it yesterday, on Linux, took under 14 minutes.

Is there a way to cross out qt* completely?

Don't remember, better ask the guys at Gentoo.

I'm not using namespaces for Qt classes. What I meant was that Qt classes are clearer/easier to identify (since their name always starts with the letter Q).

By other hand, thanks for the suggestion. I will opt for the Brainstorm section next time.
