[Message part 1 (text/plain, inline)]

Hi,

currently, icon-title-format is a variable defined in ‘C source code’.

As it's displayed at the top, it would be helpful, if it could display 
the version, for example.

What about making it customizable?

Thanks,
Andreas

What do you mean?  Can't you customize it now?

Don't see how. Tried

(setq icon-title-format '(multiple-frames "%b" ("" invocation-name "@" 
emacs-version)))

with no effect.

What window manager are you using, and which toolkit (if any) did you
build Emacs with?

BTW emacs-version is displayed instead of host-name after calling 
`dired-other-frame' - just not at the initial one.

I don't understand what you're trying to say.  Why are emacs-version and
dired-other-frame relevant?

emacs-version is the info, which I want to see at top.


dired-other-frame was just an example of a command, which displayed it 
according to my setting. Commonly, the host-name is shown at this place.

What "top" are you referring to? Is it the title bar of an iconified
window?  (I don't believe XFCE has such a thing)

It's about the display of icon-title-format's content. Which is shown on 
top of Emacs as emacs <at> foo for example. Where foo is the hostname here.

What window manager do you use?  Most of them (in my experience) just
ignore whatever the application specifies here and decides on an icon
name themselves.

`icon-title-format' is only displayed when the frame is iconified.  Is
your frame iconified?  And was any title explicitly specified for that
frame?

I'll attach a screenhot when starting from emacs -Q, just printing the 
emacs-version in the scratch buffer.

Please see at the center top displayed "*scratch* - GNU Emacs at affe"

The latest word is taken from the hostname. Want to replace this by the 
Emacs versions number.

You want `frame-title-format', not `icon-title-format'.

Ah, okay, sorry. And that works nicely:

(set 'frame-title-format '(multiple-frames "%b" ("" invocation-name "@" 
emacs-version)))

I'm closing this bug then.  I also fixed a bug related to
icon-title-format, but it ended up unrelated to your problem.
