Subject: bug#1586: prefix arg when mouse clicking on header line
Date: Mon, 15 Dec 2008 21:58:06 +0100 [thread overview]
Message-ID: <m3oczdp34x.fsf@tfkp04.physik.uni-erlangen.de> (raw)
If a command takes a mouse event and an (optional) prefix arg as its
arguments, the interactive specifications are
(interactive "e\nP")
or
(interactive (list last-input-event current-prefix-arg))
This works fine inside the main part of a window. For a command
that does the same thing in the header line, these interactive
specifications do not work. Instead one needs, e..g,
(interactive (list last-input-event last-prefix-arg))
i.e., current-prefix-arg needs to be replaced by last-prefix-arg.
This problem occured in the context of the command
proced-sort-header in proced.el, which provides a complete test
example. See also
