bug#12056: 24.1.50; Background color in selected and non-selected windows

[Dani Moncayo]

Severity: wishlist.

I'd like to be able to customize Emacs so that the selected window in
a frame had a different background color than the not-selected windows
in that frame.

This would make the selected windows to stand out over the others,
thus making very easy to see where the "focus" is.

Currently, the background color is defined by the background color of
the "default" face.  So, maybe a way of implementing this would be to
define a "default-inactive" face (similar to the "modeline" versus
"modeline-inactive" faces).

TIA.

But the default face can be remapped (hint, hint)...

But if the same buffer appears twice on a frame ...

This is currently the feature that I miss the most in Emacs.  IMO, it
would be a valuable improvement to the usability of Emacs.

Just a little reminder for you to consider.  Thanks for all your work on Emacs.

Is your problem indeed with the same buffer appearing more than once
on the same frame?  Because if not, face-remapping-alist should
provide you with the infrastructure upon which you can build this
feature for you.

No.  This is not about buffers; this is about _windows_.

I miss a simple way of making the _selected_window_ stand out clearly
(e.g. by displaying its contents with a somewhat brighter background
than the rest of the windows), in a similar way of what is currently
implemented for the selected/unselected modelines.

Well, currently I don't know how to build this feature in such way.
Also, I filed this feature request in the hope of having a simple way
of enabling such functionality, which (some day) could be implemented
upstream, so that all users would benefit from it (I believe that many
users would like it).

The idea is to write a post-command-hook which sets a
face-remapping-alist for the buffer of the selected window.
