I think that a call to Fselect_window is not enough to cause the
relevant parts of redisplay to run, since nothing really changes
on the screen.
I suspect that nothing calls redisplay. It doesn't matter whether
anything has changed in the text if redisplay is not called.
This makes me worry: is Fselect_window being called from handling of
the X event, in or called from XTread_socket? That is probably not
safe. Calling redisplay there is certainly not safe, since redisplay
can run Lisp code.
The correct way to handle this is to generate a special input event
analogous to the switch-frame event, as a list which contains the
window. Then that event can be bound to a command that calls
select-window.
This will also have the effect of making redisplay happen
when that command returns to the main loop.
- I don't understand why does the test for calling Fselect_window
insist on comparing the window, where the mouse pointer is, with
the last window where we saw the mouse pointer.
So that jiggling the mouse will not switch windows.
- Finally, the name x-autoselect-window seems unnecessarily
X-specific. Since the goal is to support this not only on X, I
wonder whether we should have a more neutral name, like
mouse-autoselect-window or something.
Yes, that is right.
