Subject: Detect content in minibuffer
Date: Thu, 30 Jan 2014 14:06:56 +0000 [thread overview]
Message-ID: <52ea5c80$0$29463$862e30e2@ngroups.net> (raw)
I'm using the following to query the size of the buffer associated with
the minibuffer but it always returns 0 even when there is a message
currently being displayed in the echo area (say, documentation by eldoc
or anything else). The aim is to not echo anything when there's
currently content in the echo area.
I've tried:
(with-current-buffer (window-buffer (minibuffer-window))
(unless (> 0 (buffer-size))
.
:
.
and [0],
(with-current-buffer (get-buffer " *Echo Area 0*")
(unless (> 0 (buffer-size))
.
:
.
What's wrong with my approach?
