Why not Trolltech release Qt 4 C++ plugin for Eclipse?

Message 1 in thread

Hi to all,

I don't find any good or decent IDE for use Qt4 OpenSource version.

I try a good OpenSource IDE , Eclipse for C++ programing and i like a
lot.
I use this version of Eclipse :

http://www.easyeclipse.org/site/distributions/cplusplus.html

The problem is that i can't develop inside this IDE for Qt4.

Why not Trolltech release Qt 4 C++ plugin for Eclipse?

I think this would be the best thing that Trolltech can do for
OpenSource developers.

Have you tried QDevelop?

Good stuff.

Oh yeah, right. That looked quite promising last time I looked (back
then it wasn't called qdevelop yet). And its written in Qt4, thats a big
plus ;)

Message 4 in thread

Our company has supplanted KDevelop with QDevelop for two reasons:

1.  It is cross platform, we can develop in the same IDE in Linux and
Windoze.

2.  You can see the contents of QStrings when debugging.  Something we never
figured out how to do in KDevelop.

Well, as Qt3 wasn't open-source for Windows, which is the reason
kdevelop3 doesn't work there. However KDE4 and kdevelop4 target Windows
as operating system too.

Hmm, that works over here with the recent kdevelop versions pretty well
;)

But well, whatever works for you is fine with me, as long as its not MFC
;)

I got the attached files to use with gdb - that way gdb get to know how
to handle Qt-classes.

For Linux OS I recommend KDevelop 3.4, downloadable from

Because TT is not paid for doing so, I guess. And IMHO the CDT plugin
isn't worth the effort, its really not that great, especially Code
Completion.

That's a nice hint; thanks Malte! However, I read something about using 
the OS version of Qt with MinGW; what about commercial versions and 
VC[6|2005] toolchain? Unfortunately QDevelop is clearly targetted to a 
gcc environment :-(

qdevelop is mingw qt4 compiler
but you can use other xp compiler...
myself i prefer mingw (gcc) ...
ms visual studio 2005 (but i don't like it too much craps)

I thought QtClipse looked good too, so I spent the hour downloading 
Eclipse, the CDT, and QtClipse, only to discover that it's no more than 
a simple tool for managing your .pro file. I can do that much more 
easily in Vim. In short, QtClipse might be useful if you already use 
Eclipse for C++ development, and you want to work with Qt in Eclipse 
also, but for me it fell short. I use Vim and xterm and couldn't be happier.

I used eclipse 3.2/CDT3.1 and Qt 4.2.2. on windows and fc5/JDK5.  I launch
qmake, qmake project, and the qt tools(designer, linquist, and assistant)
from the external tools tab on eclipse.  Create your make targets and it
works quite well.

One issue I am having on my recent migration to fc6 is that it looks as
though the fedora/gnu java isn't working as well for me as the sun jdk 5.0.
My eclipse development environment just isn't what it was on the
fc5/eclipse3.2/CDT3.1/JDK5.

Yep... it would so much nicer if Eclipse was made with QT rather then
Java :) isn't that kdevelop :)
