I think a delay is the wrong thing to do here since it makes stuff
unpredictable. The right fix, in my opinion, would be lazy focus
change: only when a keyboard or mouse event occurs in the new window,
is the focus changed. That has the disadvantage that the user may be
surprised by the change since the old window appears to have focus
before typing a key.
In order to mitigate the surprise, it might be reasonable to visibly
unfocus the old window (by the different highlighting of the mode line
and the different cursor type), but not refocus a different window
before an event occurs.
A more radical approach would be to move toolbar and menubar just
above the currently selected window. This would also require less
mouse movement, but would likely earn us an award for the most weird
user interface look ever.
I don't think it is reasonable to expect to sort this out before the
release. I think that there are several viable possibilities, and
we'd need the feedback of testers trying each of those out for several
weeks before it would be viable to decide on a sensible strategy.
I don't think that the delay stuff is a good strategy: it brakes and
confuses the user when he indeed wants to change focus, and it causes
hectic when he doesn't.

A different possibility would be to change focus visibly, but when the
mouse pointer moves out of the window and, for example, onto toolbar
or menu bar, refocus back to the original window if no intervening
event occured.
This would imply that you could not change focus only by moving the
mouse if the first action in the new window was using the toolbar or
menu bar. It would also mean quite more flicker than the "just
unfocus" variant.
Anyway:

I think it is a good change.
It doesn't change current semantics when mouse-autoselect-window == t,
but does the right thing (IMO) by adding a delayed selection option.
I haven't tested the specific change though.

Delays are the standard approach window managers adopted for focus

That could be added. But it would violate the principle of least
surprise. In my experience, the `mode-line-inactive' face and the
`cursor-in-non-selected-windows' option handle feedback pretty well.

I recall someone proposing the use of popup menus instead. There's also
the possibility to access the menubar via F10 or the ALT key. However,
clients of `mouse-autoselect-window' are probably inclined to access the
menubar with the mouse too.

Simon and me have been testing this intensively for an entire month.
Emacs developers apparently either don't use `mouse-autoselect-window'
or don't use the menubar. Otherwise they would have complained earlier.
Hence, for testing this any further we need a broader audience.

That's what I thought before I started implementing this. Currently, I
use a value of -0.5, that is, wait for about a second after I started
moving the mouse and select the other window iff the mouse doesn't move
any more. So far I didn't notice any confusion with these settings.

If you want to use the mouse to access the menubar from a lower window
but the upper window is selected before you even get there, then I'd
consider that a misfeature. Note that `mouse-autoselect-window' is new
with Emacs 22.1. I think it's better not to introduce a misfeature in
the first place.

To me it makes more sense if this "move and stop" is the default method
(ie. selected with a positive delay value). The negative value could
be for experts which want just the move delay.
But why not separate the two timeout settings, e.g. make it a cons with
the "move delay" in the car and "stopped delay" in the cdr. That's
easy to set via customize.

Yes, we should fix(!) this before the release.
Personally, I found the current mouse-autoselect-window completely
useless, and quickly turned it off again. With your changes I'll give
it another chance (haven't had time yet).

I really dislike that approach.

That would be disconcerting, IMHO.
Also, I don't see how it would help.

menubar with the mouse too.
We can't consider making such complex changes now, and I think they
would be really hard, so I doubt we should consider them later either.
That's what I thought before I started implementing this. Currently, I
use a value of -0.5, that is, wait for about a second after I started
moving the mouse and select the other window iff the mouse doesn't move
any more. So far I didn't notice any confusion with these settings.
I want to proceed with this approach, so I ask
people to study this patch in detail.

The absolute value of the delay is used to set up a timer whenever the
mouse crosses a window border. Usually though, the mouse pointer
already appears at a completely different position at the moment I
install the timer. Unfortunately, I can't access that position easily.
When the timer triggers I do (provided other conditions apply as well)
- for a positive delay select the window,
- for a negative delay check whether mouse-position is the same as the
last time I checked.
Now, the very first "last time I checked" occurs at the window border as
I explained above. Hence the first time the timer fires, the recorded
mouse-positions are usually _not_ equal and I have to restart the timer
until they are. In practice this means that if I set the delay to -1
and move to the center of another window in a single stroke, the window
is selected after 2 seconds which is more than 1 seconds after the mouse
stopped moving. Since this is slightly counterintuitive I wouldn't want
to make that the default.

Currently, there is only one delay. Do you think I should use two
different delays?

Don't (mouse-position) or (mouse-pixel-position) give the current position
when you install the timer?

Do we really need that option?

That's what I think should be the default ... don't select the window until
the mouse movement stops. But detect that quickly!

Can't you just use a (fixed) 0.1 second timer the first time ?

No. One timer "mouse-movement-stopped-timeout" would be ok.

That does not sound like anything that could work reliably on a loaded
machine, or a networked X11 session.

No. I use `mouse-position' and it gives the position where the mouse
pointer crosses the window border, in the window I move to. I didn't
try `mouse-pixel-position' but IMO it would be a bug if it did refer to
another position.

A simple delay is standard for focus follows mouse policies. I don't
really want to omit that.

You can always set the delay to a very small value. In my experience
less than 0.2 seconds never sensibly delays selection but may select the
window too quickly. It depends on your mouse mileage though, personally
I like nervous mice.
> Can't you just use a (fixed) 0.1 second timer the first time ?
It's been one of my first attempts to deal with the problem (and I used
exactly 0.1 seconds IIRC). It didn't work reliably though, and I didn't
try to find out why. Maybe another timer ...

What about a cons with the delay in the car and a boolean for
"dont-select-while-mouse-moves" in the cdr?

It is not at all standard. For example, GNOME does not offer anything
like that in its Window Preferences. What it _does_ offer is a dialog
Window Selection
[ ] Select windows when the mouse moves over them
[ ] Raise selected windows after an interval
Interval before raising: [0.0-10.0, default 0.5] seconds
Deactivating any of those lines will deactivate the following lines.
The default is "off" for all options.
I actually know of no window manager offering a delay before select.
If at all, they have delay before raise.
Raising a window is an action that changes the window configuration,
so avoiding unintentional raising is a good idea there. The
equivalent of window raising in Emacs would probably be something like
delete-other-windows (which we certainly would not want to do) or
other window-configuration changing things.

And unloaded machines and non-networked X11 connections. But not
everybody is running Emacs on a machine of his dreams all of the time.

I thought about KDE's "delay focus". Anyway `mouse-autoselect-window'
was and is by default nil. The question Kim raised was whether mouse
quiescence should be considered in the first place when delayed
autoselection is on. In this context I considered a simple timeout
"standard" because I know of implementations based on timeouts. I'm not
aware of attempts to check mouse quiescence with respect to focus
follows mouse.

In general, window managers don't have the problem that selecting an
option from a menu-/toolbar should be interpreted in the context of a
particular window showing a particular buffer.

Correct. That's why this has to be more customizable.
