Is there a hook when current window or buffer changes?

Is there a hook when current window or buffer changes?

Advising functions is limited. For example, if you select a window with
your mouse, no function is called interactively, it just changes the window.

Maybe I can use the same hook modeline uses to know how to color itself
active or inactive?

mouse-leave-buffer-hook?
mouse-select-window?
mouse-drag-region?

Not a good idea. A lot of the modeline handling isn't done in lisp.

No, `mouse-set-point' is called.

What do you want to do, at the end?

I created a thread `auto-dim-other-windows` about it.

Hi again,

to your original question: no, there is no hook and no trivial
substitute AFAIK.

The reason may be that Emacs often temporarily selects different windows
in the background.  An example is `walk-windows', which explicitly calls
`select-window'.  So, if there was a hook, it would presumably be called
all the time in situations where you wouldn't expect it.

The solution to your problem depends on what you want to do.
`post-command-hook' could be an option.


Regards,

Michael.
