problem with the gomoku sample

[Martin DeMello]

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?

Running the latest jedi and gambit from git, under linux.

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
are up-to-date, typing move-animation and pressing F12 should edit the
code.

One thing in that method is that the animation loop doesn't have any
code for slowdown. I remember when doing it that Windows's redraw-view
was slow enough as it was :-). Maybe adding a sleep in there will
help? Or maybe it is something specific to the X11 implementation that
makes the redraw-view calls not render immediatly on your X11
implementation and we are missing some X11 call to force a refresh?

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

X.Org X Server 1.6.3.901 (1.6.4 RC 1)

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!

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

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.

redraw-view forces an immediate redraw.
