[Qemu-devel] [RFC] [PATCH 0/5] Add horizontal wheel support to mice, where possible

[Brad Jorsch]

The emulated mice should emulate a horizontal wheel when possible. This
patch series does that for the USB mouse and tablet and the ExPS/2
mouse. As far as I can tell the vmmouse protocol doesn't handle a
horizontal wheel, and I have no idea if emulating a wheel might make
sense for any of the other mouse types.

I've tested this using the SDL interface and an Ububtu 10.04 cd image;
xev reports the correct events for all three devices, and a gedit window
with sufficient text to create scrollbars scrolls correctly with both
mice (didn't test the tablet). More testing would be good.
