[gcompris-devel] gcompris and gnome 2.2

[Olivier Samyn]

Hi all,

since I'm new here let me present my self before I speak you about a bug
:)...

I'm an informatic engineer from brussels, I'm the creator of two small
projects (yafi and pig) and I participated past a lot in IceWM.

I met Bruno this week-end at fosdem and proposed him to try to implement
python bindings into gcompris...

Here is for the presentation.  Now the bug...

Since I'm using at home a Linux From Scratch, I update my system to my
own comiled Gnome 2.2 version. This week-end I tryed to run gcompris on
this box and I got some hugly bugs in display refresh.

After some hacking I found that:
- In the latest release of gnomecanvas they removed some display
updates.
- One of the demos of gnomecanvas doesn't work on my system without
patching it.
- Some GCompris plugins react with the same behaviour as this gnomecanvs
demo. So GCompris doesn't work well.

After some more hacking I found a way to patch the gnomecanvas demo by
adding some: "gnome_canvas_update_now(canvas);" calls.

Having this demo working, I began to patch gcompris (see below) and get
it working a lot better on my system. (I don't tested all plugins
already, my gaming time beeing reduced by having to sleep a bit :) )

So, all this blabla done, I propose you my patch against gcompris 2.1
bellow and I ask a question: Does anyone noticed the same behaviour on a
gnome 2.1 or 2.2 system ? And in both cases, is a patch a solution, or
does I (we?) have to report some bug to gnomecanvas developpers ?
