Subject: 25.3; height of echo area when displaying tooltip

Hello,

If I have disabled tooltip-mode, is there a way to tell Emacs that it should expand the height of the echo area (where tooltips are displayed) if the tooltip is longer than the screen is wide? Currently the words just run off and I can't see them.

Additionally, I believe the info manual and docstring for `x-gtk-use-system-tooltips' may need updating. In section 21.18 Tooltips, it says "If Emacs is built with GTK+ support..." and goes on to state that users can change `x-gtk-use-system-tooltips' to nil. However, I was under the impression that the recommended way to do this was to call (tooltips-mode -1).

Thanks,
Alex

I'm not sure it was on purpose: the log message which introduced the
above says "to closer match the behavior of C code".  But I guess you
are right that someone could become annoyed, so I added a new
defcustom and pushed the change to the master branch.

Note that this option is only effective on GUI frames.

With that, I'm closing the bug report.

Thanks.
