quitting a completion

quitting a completion

[Klaus Berndl]

Suppose i hit C-h v and then insert "gnus-" and then hit TAB then the window
gets splitted (if only one window in current frame) and a *Completion*-buffer
is offered - well. If i then hit C-g (`keyboard-quit') then the
*Completion*-buffer and the newly created window go away - well too.

Now my question: Which function is called by Emacs or which mechanism deletes
this newly created window when quitting such a completion?

Thanks a lot in advance!
Klaus

I'd be glad if someone could tell me too how to close these 'pop-up
frames'.  They are pretty much annoying when they refuse to leave...
(using emacs version 21.2.1)

I guess you mean `windows'.

C-x 0 delete-window
C-x 1 delete-other-windows

The key to finding out the answer to this is to realize that TAB
during completion calls `minibuffer-complete', and the *Completion*
buffer is displayed by `minibuffer-completion-help'.  Both are
built-in functions, written in C.

What they do is call an equivalent of `with-output-to-temp-buffer',
which pops up a temporary buffer and takes care of restoring the
window configuration if you type C-g (or in case of any other exit
from completion).
