Hello, I'm a Linux user and I'll want to program with a GUI. I want to ask you which one should I learn, because I'm really confused... and, if you can, please give me a link to a manual, thanks!.

If you're doing straight C, GTK+ is probably best. Most other toolkits (wxWidgets, Qt, FXWidgets) are designed for C++.
http://www.gtk.org/
most linux ide's are multilanguage, and your distro will have the documentation for the ides they have available.
for a "polished" look and feel to the gui, that is similar to ms visual c++, kdevelop, kde studio [ commercial version of kdevelop ]
or qt designer [ c++ only }
glade is a gtk/gdk ide for user interface and event handling.
the only drawback to glade is that the documentation is not complete.
almost all gui applications use c++ or delphi for the interface [ java being the exception ]
[ delphi only if using borland's tools, which require the 2.4 kernel at the latest ] so you will have to learn to work with c++.
unless you are using Xandros, which uses emacs as the default development environment, I would recommend using kdevelop to learn with. http://www.kdevelop.org/
the full documentation for it is there, but use your distro supplied binary rather than build from sources, some distro's have altered a few things making build from sources more difficult than it should be.
Ok, thanks for your help, now I'll learn C++ and then QT (I want to develop KDE applications), or maybe I won't learn C++ and I'll use PerlTK :P THANKS!
Isn't GNOME gaining much faster acceptance than KDE? Would it therefore not be better to use GTK+ instead?
Or is my thinking here completely incorrect?
From what I've seen, KDE has more acceptance, but I might be wrong. The recent GNOME versions are supposed to be very good. But bad experiences in the past have led me to use KDE exclusively.
If GTK, though, use GTK--, the C++ wrapper for GTK+.
Apparently, most of the major distributions have either already accepted GNOME as their standard default, or they are in the process of doing so. Most government institutions corporations I know that use Linux use GNOME.
However, and I am sure this counts for a lot, Linux Torvalds himself has come out quite strongly against GNOME and endorsed KDE. He says that GNOME's philosophy of assuming that "the user is an idiot" is most irksome to him.
I prefer GNOME because I am more of a C guy than a C++ guy. But I do use both, and I think that KDE is very nice too.
Well, I always had extreme problems with Gnome's session handling. It would launch all sorts of programs on startup that I might have had open at one point - but definitely not when I last shut it down. This became very tiresome, especially as it insisted on opening several instances of Firefox - and you probably know what that means. (Annoying profile selection dialogs.)
I also find KDE to be better integrated - I get the feeling that everything works together perfectly when I right-click a file in amaroK, choose "Burn->This Album as Audio CD" and it launches K3B and burns. It's just ... smooth.
On the other hand, and to get back on technical aspects, I have to admit I don't particularly like Qt's 2-step compilation.
But then, I haven't done very much with either of the two toolkits. I'm more of a console guy.
Hello, I am a Linux user, but recently I have been using the J programming language. J is more powerful and terse, but it can get more cryptic. It is good though.
Ah... If you're going to use PerlTk, why not go all the way back to it's roots and learn Tcl; then you can use Tcl/Tk, which is where it all began. :pQuote:

What is J++? I guess it is like C++ for J (haha). Well, J was made in the late 90's by two programmers. It is yet again an object oriented language. It is basically the most powerful language out there.
You have a link describing the language? I am extremely wary of "most powerful languages". I've seen too many of those.
J++ was Microsoft's early Java dialect, which they were forced to discontinue after Sun sued.
Hi
"Apparently, most of the major distributions have either already accepted GNOME as their standard default, or they are in the process of doing so"
I am a Slackware user and after Slackware 10.2, GNOME will not be supported by the Slackware any more. But i use WindowMaker and actulay don't like KDE!
"He says that GNOME's philosophy of assuming that "the user is an idiot" is most irksome to him."
Yes, i read something about this!
GTK is gives you a C apı but there is a C++ wrapper called GTK--. Although GTK gives you a C API, the programming technique requires a OO language I think.
For exmaple
can be done better by something like this...Code:windw=gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(windw),"Title comes here");
gtk_container_set_border_width(GTK_CONTAINER(windw),0);
g_signal_connect(G_OBJECT(windw),"delete_event",G_CALLBACK(delete_event),NULL);
Looks easier... :)Code:GtkWidow windw;
windw.set_title("Title comes here");
windw.set_border_width(0);
windw.signal("delete_event",G_CALLBACK(delete_event),NULL);
Maybe GTK-- provies such an interface (I have never used it!).
And also, one advantage GTK over Qt (according to me), some simple programs that does not require lots of system dependets features, written in GTK can be ported to Windows, there is a GTK lib for Windows! As I know, there is no Qt library for Windows.
yup, QT for windows does exist.Quote:

Never used it, never intend to. If he meant it is more powerful than C, well, I'll let the mob decide.
Meh. Talk about unreadable and specialized ...
Apples and oranges, if you ask me. J doesn't look like a general-purpose language.
As it says, J is "array programming language" and is geared more towards mathematical studies. Seems a fairly irrelevant language.
I prefer kde over gnome, I run bsd so neither window manager is prepackaged into the setup. Which you use is unimportant because I assume most users who want graphical apps have both bases installed.
As for J being "the most powerful language", that's an improper use of english, I would say either an architecture's assembly or vhdl, veralog, or some other hardware mapping language is "the most powerful".
I'd use GTK because I've heard that GTK code is portable for Windows. Firefox uses GTK.
Firefox on Windows uses Win32.
For programs that use GTK to run on Windows, look for Gimp and Dia.
just to add on here, i didnt see wxWidgets in there.. i prefer Qt just because im pretty familiar with it. however there are *lots* of choices.. the common mainstream ones are the best way to go though, you will be able to find support alot easier..
>> I personally like the enlightenment desktop environment, as far as possible from looking like windows.
Yes me too.. not so much just for the looks, but the power. I have used a good many of the window and desktop managers available and havent found any that are useful and clean as e. dont confuse it though, its not a desktop.. just a window manager..
>>Only Qt 4 is available under the GPL for Windows, though, and I think it's only in Beta or RC state. Qt 3 must be bought.
there is a non commercial version of Qt3 that is available.. it is just hard to find.. i dont even remember where i got mine from but google knows.. ;)
actually, all mozilla products use gecko and xul, not gtk.Quote:

Gecko is just a rendering engine, rendering to Mozilla's graphic context. XUL is an XML language that is interpreted by Mozilla and rendered by Gecko.Quote:

I had the impression that GTK2 was available for Windows since there is a GTK extension for PHP on Windows.
Is is.
