delete-frame raises other frames

delete-frame raises other frames

[Matt McClure]

Hi,

When I do C-x 5 0 or M-x delete-frame, my Emacs raises one of its other
frames. I'd prefer that no Emacs frame would raise and that my Mac would
show whatever windows were previously under the just deleted frame.

I made a 20-second screen cast[1] that shows the problem.

   1. I start with a Terminal window.
   2. I start Emacs with `emacs -Q`.
   3. I create a second frame with C-x 5 0.
   4. I stack the three windows from top to bottom:
      1. Second Emacs frame
      2. Terminal window
      3. First Emacs frame
   5. I delete the second Emacs frame using C-x 5 0
   6. I observe that the first Emacs frame raises over the Terminal window.

How can I make the first Emacs frame stay under the Terminal window when
closing the second Emacs frame?

PS. I reported a similar issue[2] using emacsclient. Maybe they have the
same cause.

Is auto-raise-mode enabled or disabled in your sessions?  If it's
enabled, try disabling it.

Does Mac not have a system-wide window manager key to close windows,
like Alt+F4 on Windows and most X11 window managers?

Seems disabled.

(frame-parameter nil 'auto-raise)
nil

I can create and close Emacs frames using Cmd+N and Cmd+W respectively. The
resulting window stacking order is the same as when I use C-x 5 2 and C-x 5
0.

Any ideas where I should look next? I'm happy to look at the implementation
if there's no user-configurable solution.

Well, this doesn't happen to me, and from lack of other "me too"
responses, I'm guessing that this is either specific to OS X or even
to your system's configuration.

I know nothing about GUI on OS X, so I cannot help you where to look
for the cause.  Hopefully, someone else will.

Thanks, Eli.

My guess is that it's specific to OS X.

I looked at the Emacs source code a bit. I found the following in
delete_frame[1]:

```
#ifdef NS_IMPL_COCOA
      else
/* Under NS, there is no system mechanism for choosing a new
  window to get focus -- it is left to application code.
  So the portion of THIS application interfacing with NS
  needs to know about it.  We call Fraise_frame, but the
  purpose is really to transfer focus.  */
Fraise_frame (frame1);
#endif
```

The following might also be relevant:

   - Apple's window concepts documentation[2]
   - Uses of NSApp[3], e.g.,
      - activateIgnoringOtherApps[4]
      - makeKeyAndOrderFront[5]
