Subject: Precision scrolling with mouse whell on MS-Windows
Date: Wed, 01 Dec 2021 15:44:34 +0200 [thread overview]
Message-ID: <83lf14sam5.fsf@gnu.org> (raw)
I've implemented this on MS-Windows. Unfortunately, I cannot fully
test this, because I have no access to any system with such a mouse.
So someone else will have to test this and find all the bugs in my
code.
One note: unlike on other systems (I think), the MS-Windows
implementation is sensitive to user's system-wide setting of what is
"scroll unit". This is normally a small number of screen lines (by
default, 3), but can also be "the whole page". The code I wrote
computes the pixel deltas in as a fraction of this "scroll unit".
