You can switch to non-contiguous mode to avoid scrollbar.
This is a tablet. Its designed to scroll with the flick
of a finger. In non-contiguous mode you can't scroll at all.
To change pages you have to touch a tiny little button at the top
of the screen. very hard.
It’s a bigger change than just removing a scrollbar from contiguous ,
but I’m not aware of any Windows software that has such “scrollbar
without a scrollbar” mode.
Things must have changed since I retired in 2001. But as a programmer
I had full control of scroll bars. It was just a flag you set along
with the location.
You still would have to respond to input. Perhaps an option where
you just don't do anything when you get a scroll request.
Are you not encountering such scrolling problems in, say, a web browser?
If not, what the browser does to prevent that?
This is very interesting. In other programs, such as a browser,
you must touch the scroll bar and nothing else. Since a misplaced
thumb covers it and also touches outside the bar region, the
action is ignored. Unfortunately sumatra doesn't test for this
condition. Any kind of casual contact instantly plunges me to
another part of the book I'm reading.
