Re: patch for optional inhibit of delete-other-windows(IDE feature)

My question was badly formulated.  I wanted to know whether the
edit-area could be always obtained by recursively splitting a window in
some arbitrary way such that the resulting tiling would encompass the
_entire_ edit-area.  That is, none of the windows produced by these
splittings would not be part of the edit-area.

A simple example not following this concept would be: Split a window
vertically, split the lower window vertically, the upper two windows
(and their sub-windows) would constitute the edit-area, the lowest
window would not be part of the edit-area.

I'm asking because currently reasoning about tiling Emacs windows is
purely operational.  A tiling is always the result of recursively
splitting an initial window into sub-windows.

Does that mean I can't run ECB in two frames simultaneously?

I suppose this will be the basic invariant.

Is the compile window you mention below not a special window?

OK.

How do you currently display the compile window, make it go away,
display it again, ... ?

I suppose you mention `next-window' here because you use it to modify
the standard commands - sometimes they should operate on the full
windows list, sometimes just on the edit-area list?

I meant "select", for example, using `other-window'.  How do you select
the compile-window or the other special ECB-windows when you're in the
edit-area?

Does that mean special windows are not fixed-size, so the user can
freely resize them?

We should be able to do this using window-configurations.

Sure.
