Eirik Bakke commented on NETBEANS-49:
-------------------------------------
OK, let's discuss Approach 2, then.
The main requirement is to override BasicScrollPaneUI's
createMouseWheelListener. For LAFs that add their own ScrollPaneUI class that
extends from BasicScrollPaneUI, this must be done by extending from said
LAF-specific class instead of directly from BasicScrollPaneUI (so that we
retain whatever other functionality the LAF has added to BasicScrollPaneUI).
I had a quick look in https://github.com/Revivius/nb-darcula and could not
actually see the ScrollPaneUI being overridden anywhere. Maybe I'm wrong. But
in any case the existing patch does not seem to work on Darcula on Windows 10.
Some investigation would be needed here.
Also be aware that if the code in the patch ends up being copied to Darcula, it
will have to be updated in two places if we later make other improvements (e.g.
to fix the Surface Book problems you mentioned earlier).

> Inside the editor, when I scroll with my touchpad to the bottom, it jumps 9
> lines to the next, this is a lot. I don't like such gappings I would like to
> have a smooth stepless scrolling, like in chrome or other windows native
> apps. Please add this for horizontal and vertical scrolling, it will be much
> better. Not only in editors, it should be available everywhere, where we have
> scrollbars.
