latex-beamer + pstricks???

[lilostitch]

sorry maybe most people would say that beamer is not supposed to work
with pstricks, use pgf!
but I am too lazy to learn pgf, and I am afraid pgf is not as powerful
as pstricks to implement what I want:


I want a
equation;
\[ A + B=c\]

I want to show the equation in 3 steps,
A , then draw a arrow from outsize, pointing to A,
then same to B, then same to C,

problem is,
I use \Rnode{A} to remember the position for the pointer,
then use \uncover<1-3>{\ncarc{A}{outside_A}} to draw the arrow,
it seems that the arrow is always drawn, not in time steps,

anyone has a take on this??
thanks a lot!

here you find a guide that tells you how to make pstricks work with
latex-beamer

http://www.geocities.com/kijoo2000/beamer.html

I found it quite useful!

hope it helps

thank you very much! this is a very nice tutorial

I tried the tricks from the tutorial, it does not fully solve the
problem
I have the following .tex beamer file
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentclass[xcolor=pst,dvips]{beamer}
\usepackage{pstricks}
\setbeamercovered{transparent}
\begin{document}
\frame{
A
\only<2>{\psframebox{B}}
\pause
\psframebox{C}
\pause D
}
\end{document}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

(1)theoretically, it should first display A, with B,C,D being
semi-transparent,
then display B, then C, then D

but the second step completely hides B,
(2) furthermore, if I delete the xcolor=pst,dvips option,
the file does not compile at all, and gave me some weird errors

wait a second, I found the cause of the second problem (2):
it was because I had the 1999 version of pstricks,


but if I use 2005 version of pstricks,
i can not put the xcolor=pst,dvips options on,
because it gave me errors:

do not use the xcolor=pst option, it is really obsolete.

thanks, Herbert,
then is it possible to make the \psframebox show as semi-transparent in
the \only{} clause??
