Does anyone have any experience doing OpenGL stuff with Qt4? If so, what was it like? Is it worth the trouble
to learn how to do it?
Thanks in advance,

Very easy when you know the basics of opengl. Just read the tuts
on the Opengl-Page and this one:
http://www.digitalfanatics.org/projects/qt_tutorial/chapter14.html
Here are some of the nehe-tuts ported to qt.

Thanks!
But how does Qt compare to other GUI toolkits? Is there a relevant performance penalty?
Once again thanks for the help, Kevin. Kudos!

Just for the record, chapter 20 of the book Jasmin Blanchette and Marc
Summerfield, "Qt GUI programming with Qt4", 2nd ed. Prentice-Hall, 2007
has an introduction. Once you have Qt4 installed (and OpenGL), the
OpenGL examples in that chapter compile and execute immediately.

I defy anyone to pick 3 QT-based OpenSource projects and be able to compile
them.
I just found kdocker myself, and compiled it no problems.
from source, fetched from sourceforge, i admit it was a small program.
But i take a larger challenge if you come with a link.
Maybe something that has troubled you before?
compiled with no problems.
use qmake for version 3.xx, qmake --version
for unix change the envirnmoent or specify paths to QT tools
Ie. the moc compiler, qmake etc.
Often QTDIR need to be specified before compiling or in the .pro file.
Specially since QT4 often is the first rate citizen while QT3
by many systems are treated legacy like.

What compatibility issues does Qt have and where exactly is Java superior in that aspect? Moreover, Java's
slowness is something that simply can't be ignored.

How is this any relevant? Nonetheless, the only Qt app that I bothered to install from source was the new
release of Psi, which compiles rather flawlessly.

What i mean by this very bad wording is just that
when QT3 and 4 is installed mostly QT4 will be in the environment
and the qmake binary will be the QT4 version, and so on.

Exactly so, the aforementioned "compatibility issues". The O.P. was asking
about a QT3 widget.
I dislike any interface that make big incompatible changes from one rev to
the other, on principal. Wastes my time and I have none to waste.
