Select two files in the Navigator view, right click>compare with>each other. The
mouse wheel doesn't work on the created editor.

Works on win32

Chrix to investigate and advise

Internal comment. Check wich events the StyledText/Composite get when the 
mouse wheel is moved - find why it is not propagated to the scrollbar driving 
the compare view.

WinXp, JDK 1.4.0_02

In the compare editors, the mouse wheel scrolls the windows left and right 
rather than up and down.  It works correctly in the editors
Comment 3 Veronika Irvine CLA 2003-02-21 10:48:27 EST 
On Windows:

If the mouse driver does not handle the mousewheel, the SWT code looks for a 
vertical scrollbar and if none exists, it looks for a horizontal scrollbar and 
scrolls it instead.  This is the same thing most mouse drivers that are aware 
of the mousewheel do.

On GTK:

GTK sends the events.  There is no code in SWT managing this.  In all 
likelihood, most drivers behave as the windows drivers.

I think this bug is out of date, works fine for me.
Comment 5 Billy Biggs CLA 2004-09-22 17:42:13 EDT 
Sorry, it is broken for me.  It's not broken in I200409211200 which had a busted
compare editor. :)

The problem was that GtkScrolledWindow will not send scroll events if the
scrollbars are hidden.

It's still the same in Eclipse 4.5.1. I'm on 64bit Ubuntu 15.10 beta with Unity.

Compare with bug #473851.
