compiz - Mar 2007 - AW: Re: [PATCH] minimize doesn't respect "no core instance" flag

Hi,

Let me ask in a more general way:

A plugin wants to hide windows by preventing their drawing - that's all
group wants to do.
What's the correct way to do that? From my understanding, that's
NO_CORE_INSTANCE_MASK. If that's not true, what's the exact meaning of
that flag?
Another way to do that would be to just return from paintWindow instead of
calling the next plugin, but I think that's a bad solution.

Regards,
Danny

Plugins are not supposed to look at the
PAINT_WINDOW_NO_CORE_INSTANCE_MASK flag. It's supposed to be a
write-only flag for plugins.

I'm not sure what's the best solution is here as I don't know
exactly
how the group plugin works. Checking if the
PAINT_WINDOW_NO_CORE_INSTANCE_MASK flag is preset is definitely not the
correct solution though.
