No Horizontal Scrolling in Guest VMs

[JWC]

As per: ​http://forums.virtualbox.org/vieatopic.php?t=1794

VirtualBox's mouse driver (the one installed with the Guest Additions package) doesn't seem to support horizontal scrolling, although it supports vertical scrolling quite well.

Supporting this mouse should not be a big problem but as we don't have such a mouse handy, it is difficult to test. I've added a small SDL example application which you can compile on a Linux host with

gcc -O2 -o sdlkey sdlkey.c

Ensure you have the SDL development stuff installed. Start the application and try horizontal scrolling while you are over the SDL window. What is the output of the example program?

Sorry for the long delay.

Scroll Left: (event->type=5) BTNUP: 6, 1 (event->type=6) BTNUP: 6, 0

Scroll Right: (event->type=5) BTNUP: 7, 1 (event->type=6) BTNUP: 7, 0

Blegh, forgot to <pre> that.

Scroll Left:

(event->type=5)
BTNUP: 6, 1
(event->type=6)
BTNUP: 6, 0

Scroll Right:

(event->type=5)
BTNUP: 7, 1
(event->type=6)
BTNUP: 7, 0

Thanks for the response. It will probably took a little bit more time to implement this because the IMPS/2 mouse we emulate seems to not support horizontal scrolling.

Sounds great! I hope everything works out well. :)

Are there any plans to implement a fix for this problem?
