Re: [Scidvspc-devel] Patch1: Eval bar for boards, inturn Enabled for Analysis Board

[Steve A <ste...@gm...>]

Hmmm... Looks nice :) but it keeps disappearing on my macbook.
It's normally not viewable ??

But what you are doing is not too well designed.
How are you going to connect the main board (or, say a fics observed board)
to an engine.
It looks like this only works with engine mini. boards.
Moreover, it is *very* complicated to put in a generic board eval class.
For example - say i have no engines running, but am observing 3 fics games
as mini boards
I need three extra engines running in quiet mode to show eval bars on the
observed games. Kindof impossible.
A generic board eval bar would be great for the game browser (for example),
but just way too hard imho.
Of course putting one on the engine mini board (like you have done - except
it keeps disappearing on my mac!) may be a great idea.

Have you noticed i've already coded an eval bar yesterday.
I should probably make it work with *any* engine rather than the second
engine only.

I haven't given linear/log any thoughts. At the moment my bar is just +-5
linear.
What do other websites / guis use?

Cheers
