Unix scroll bar issue #162
Description
ReClass is working fine on Ubuntu, but any action (like editing a value or expanding a tree node) scrolls the view all the way to the top.
Also, pressing the down arrow on the vertical scroll bar has the same effects and scrolls back up.
Grabbing the scrollbar crashes the application.
Little demo to make it more clear: video here

This problem was introduced with 98141f2. A quick fix would be to use the broken implementation when running on unix but I'm not really happy with that.

I rewrote the scrolling system and removed a lot custom code which was not needed. Now it works on both platforms without problems.

Thanks for the update, scrolling indeed works now.

You have edited your answer. Is the "scrolling to top" behaviour still an issue?
