Description michael@smith-li.com 2005-04-09 15:32:50 UTC

This is a feature request for mouse wheel support in Linux Eclipse IDE.

Reproducible: Always
Steps to Reproduce:
1. In Eclipse, open a text file that's large enough to make scrolling necessary.
2. Make sure the text file is in focus and the mouse cursor is over it.
3. Scroll mouse wheel.
Actual Results:  
Sometimes certain words in the text will become highlighted/selected.

Expected Results:  
The page should have scrolled in the direction of the wheel motion.

Gentoo Linux eclipse-sdk-3.0.1-r2
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_07-b05)
Java HotSpot(TM) Client VM (build 1.4.2_07-b05, mixed mode)

The mouse wheel works in Windows (and in OS X according to some googling.)

Is maybe your mouse not correctly configured in X?  This should work just fine ...

Open a terminal window and run 'xev'.  Move your mouse into the window and scroll the mouse wheel.  What events are being sent?  It should be button 4 (up) and button 5 (down).

My mouse seems just fine. No, I wouldn't have reported it as just a problem with Eclipse if I'd had problems with other programs. To be sure, I took your advice and ran xev, and yes, button 4 is up and button 5 is down, just like my xorg.conf says.

Comment 3 Rune Schjellerup 2005-05-13 03:40:31 UTC

I have the same problem.
Mouse wheel works everywhere else but not in eclipse.
Running Xorg-X11 and KDE

Comment 4 Billy Biggs 2005-05-15 04:20:37 UTC

Is this still reproducable if you get the eclipse builds from eclipse.org rather than using the gentoo ebuild?

Comment 5 John Susi 2005-06-16 16:24:27 UTC

Are you running the motif version of Eclipse perhaps? 
 
from the SWT FAQ 
http://dev.eclipse.org/viewcvs/index.cgi/~checkout~/platform-swt-home/faq.html#scrollonlinux 
Not sure if this applies to eclipse though, just a thought.  
 
Running eclipse 3.1_rc1 using GTK and scrolling works fine.

Comment 6 John Susi 2005-06-16 16:34:10 UTC

Can confirm that eclipse 3.0.1 using "-gnome -gtk +kde +motif +mozilla" 
does not work with the scroll wheel.

I suspect this has to do with the motif library. Please test the binary drop
from eclipse.org. If it has the same problem, report the problem upstream. If
the problem resides with us, reopen this bug.
