I know that it is supposed to be useful for compiling cross-platform versions of a program, and that it has something to do with C++ ...not a problem so far. But - if QT compilies a program for Linux (my interest)... why do I have to install QT (again) to use it ? It seems it hasn't compiled -FOR- Linux at all, but is only using the Linux framework to run itself on_ acting more like a virus than a useful program... providing a whole new set of requirements, which Linux/linux users aren't especially prepared to handle. QT isn't open source... installing the QT "helper app" takes 10 times longer than the entire Linux installation did ! What is QT really good for, other than that several commercial programming companies used it to develop their commercial products ? With all of this, I am reading that using QT for new programs isn't possible without paying a huge premium... why are Linux distributions including QT programs at all ? KDE was purportedly developed with QT, and I use KDE without any problems... but this isn't how the QT problem apps are working. ...isn't there some simpler C++ open source alternative to something like QT ?

For example, Qt is offered under multiple licenses, some of which are open source--see http://www.trolltech.com/products/licensing.html In any case, this isn't the place to discuss Qt. To understand why not, read the comp.lang.c++ welcome message: http://www.slack.net/~shiva/welcome.txt The best place for questions about Qt is the "Qt Interest" mailing list: http://lists.trolltech.com/qt-interest/ If you prefer, you can access the mailing list through usenet: http://www.trolltech.com/newsapply.html Before posting, I would check out the Trolltech FAQs: http://www.trolltech.com/developer/faqs/index.html Hope that helps, Russell Hanneken [email]rhanneken (AT) pobox (DOT) com[/email] Back to top Jim Fischer Guest Posted: Mon Jun 30, 2003 6:01 am    Post subject: [OT] Re: QT problems Vinodh Kumar wrote: Quote: What is QT?

But - if QT compilies a program for Linux (my interest)... why do I have to install QT (again) to use it ? No idea what you mean here. Also, Qt doesn't compile programs. It is a library that is linked to them. Quote: It seems it hasn't compiled -FOR- Linux at all, but is only using the Linux framework to run itself on_ acting more like a virus than a useful program... No idea what that means. What is "the Linux framework"? What do you mean by "compiled -FOR- Linux"? Quote: providing a whole new set of requirements, which Linux/linux users aren't especially prepared to handle. What requirements? Quote: QT isn't open source... Wrong. Quote: installing the QT "helper app" takes 10 times longer than the entire Linux installation did ! What "helper app"? Installing how? Did you compile it yourself? Then it may very well take longer than just installing (whithout compiling) a linux distro. Quote: What is QT really good for, other than that several commercial programming companies used it to develop their commercial products ? With all of this, I am reading that using QT for new programs isn't possible without paying a huge premium... No. You only have to pay them if you want to distribute your program, but not its source code. And they aren't so huge at all. Look at the typical prices for development tools, and you'll see. Quote: why are Linux distributions including QT programs at all ? Why not? Quote: KDE was purportedly developed with QT, and I use KDE without any problems... but this isn't how the QT problem apps are working. No idea what that means. What's your definition of "QT problem apps"? Quote: ...isn't there some simpler C++ open source alternative to something like QT ? There are lots of alternatives. You know, I think you're just a troll. Back to top stu7 Guest Posted: Mon Jun 30, 2003 6:50 pm    Post subject: Re: QT problems "Russell Hanneken" <rhanneken (AT) pobox (DOT) com> wrote...

KDE is made with QT. QT and wxWindows are the only cross-platform OO toolkits I know of that can be considered reasonably complete. From what I've seen, QT is much more friendly to the developer. wxWindows is similar to MFC. What about the Mozilla *framework*? Though, they have a lot of work to be done, it seems to be quite promising...... -Dhruv.

No idea what you mean here. No idea what that means. What requirements? Wrong. No. *** nothing useful from this response so far... Not less useful that your comments that they are written to. You mostly wrote garbage that I didn't even understand and things that aren't true. And in that posting, you didn't explain anything. Quote: *** oh wait, heres one...

Quote: (then I said) I am reading that using QT for new programs isn't possible without paying a huge premium...

Look at the typical prices for development tools, and you'll see. *** I saw $1500, and other prices... but we never answered why the *** Linux community is snarled up with using a non-free program ? Qt is under the GPL. Have a look at http://www.fsf.org to find out what free software is and why GPL'd software is considered free software. Quote: *** So $1500 isn't huge ? OK, send me the paltry $1000, and I'll laugh *** along with you Well, if you want to make money, you first have to pay money. It's called investment. If you want to start a software company, you're quite unlikely to succeed if you can't afford $1500 for it. Quote: Why not? No idea what that means. There are lots of alternatives. *** but... he didn't name any You didn't name your problems you had with Qt. Also, have you ever heared of google? It's quite useful to find things on the www, just like those you're looking for.
