Hi Guillaume,
sorry for this very late reply.
Please don't waste your time with this "bug" and continue your fine work
on Jazz/Jedi by adding features, cleaning up code or even optimizing the
drawing routines (I think I mentioned already, that the UI redraws too
much). Of course you could try to use cairo_surface_create_similar to

Re: Windows binary anywhere

When JazzScheme was released 9 months ago, we took the time to build
binaries for Mac, Windows and Linux. Unfortunately we haven't had the
time yet to automate this lengthy process yet. And as Jazz is evolving
rapidly with many commits each day, I decided the best was simply to
remove binaries and references to them from the website (I have now

Hello,
The windows binary are mentioned in the site, but I cannot find them.
Are they available?

Re: problem with the gomoku sample

That's the difference between invalidate-view and redraw-view.

invalidate-view tells the windowing system a certain area must be
refreshed at the next paint. So multiple calls to invalidate-view will
just accumulate and the next paint will draw the union of those
invalidated areas. This is usually what we want.

ah, okay :) why does invalidate-view not cause a redraw?

Sorry about that, I had read C4 :-)

Then, everything is as it should be. It does the same thing on Windows
and Mac. I'll add a redraw-view, so apart from being nicer, no one
else will go thinking it's a platform specific bug ;-)

Thanks!

Guillaume

Hi Marco,

First of all, many thanks for such an exaustive analysis of the
problem! It is very difficult and frustrating to try and debug a
problem like this without access to reproducing it but your help sure
goes a long way!

After reading your email, it seems to me the most promising approach

Re: problem with the gomoku sample

2009-10-13T18:42:21Z

No, C4 works fine, it's gomoku that has the problem. Here are the
details from xorg.log, in case they help:

Strange, it works correctly (e.g. with an animation making the piece
slide down the column) on both Windows and the X11-based version in
Mac OS X.

If you want to take a look at the code (I do not have access to a pure
Linux station), all happens in the move-animation method of the
C4-Board class. It's a very simple few lines method. If your catalogs

When I run the gomoku sample, the board isn't redrawn until both I and
the computer have played. That is, I click, nothing happens, there is
a perceptible delay while the computer thinks, and then two pieces
appear at once.Is there an issue with invalidate-view?

FAQ

2009-10-08T19:48:23Z

I added a new FAQ page to the JazzScheme website:
[link].
For the moment, it contains an extract of every usefull Q/A on this
group since it was created 2 years ago. I plan on adding more in the
future.

Hi Martin,

I added a new "Hello World in many flavors!" section to the tutorials
page: [link].

By building up step by step to what the IDE automatically generates
for you when you create a new project, I hope it will help in getting
a better understanding of the underlying structure of repositories,

X11 performance tests/results

Hi all,
1 Introduction

I try to summarize the tests I made to improve (or better track down
the cause of) the poor performance that some of us have seen with
Jedi on Linux/X11. The effect can be described as an pixel wise
redraw of the Jedi GUI, it is so slow that you can see it is painted
