bug#32597: gdb gud-watch speedbar no visible actions

[Ergus]

1) "M-x speedbar" requires to be called twice for the first speedbar open. If
this is not a bug, it is very weird.

2) Debugging with gdb in emacs a C program I added a gud-watch for a struct
variable. Going to the speedbar I try to open the struct tree [+] with <SPC> but
it does nothing (i don't try mouse click because I am in a terminal session).

- It requires to quit (q) and open the "M-x speedbar" again to show the
speedbar updated with the tree opened. It opens depends if I pressed
<SPC> odd or even times before q.

- The opposite (close the tree) works properly without exit needed, but I can't
open it again (previous explained behavior).

- I tried this with -Q option to check that it was not a mistake in my
configuration.

- The speedbar in: "emacs -Q -f speedbar" works fine without this issue.

- With emacs in gui there is not problem either.

Not sure I understand you correctly: does the last part of your report
mean that the problem does not happen in "emacs -Q"?

Yes it happens also with -Q.

When it doesnt happen is in gui mode.

So it only happens in a -nw session?

bug#32597: gdb gud-watch speedbar no visible actions

[Glenn Morris]

I didn't even think speedbar worked in -nw sessions.
In the manual I read that it does, but in a weird (IMO) way:

    When used in terminal mode, the new frame appears the same size as the
    terminal. Since it is not visible while working in the attached frame,
    speedbar will save time by using the @dfn{slowbar mode}, where no
    tracking is done until speedbar is requested to show itself (i.e., the
    speedbar's frame becomes the selected frame).

Maybe this explains some of what you see.

You have to use "speedbar-get-focus" to see it.

It seems odd that M-x speedbar has zero visible effect.
No message, no (visible) buffer created.

A message (to the effect that one needs an additional command to show
it) might be appropriate.  Anything else would IMO annoy on a TTY,
since, if we display the Speedbar frame, the "important" frame will
disappear from view.

So I've now done this in Emacs 29.
