Hi.
I added support for touchscreen scrolling to kdrive and tslib-based X
servers. With that patch, screen dragging can generate mousewheel
events instead of dragging events. This behavior directly conflicts with
those parts of e that try to implement that dragging-as-scrolling
functionality in the application instead of in the driver. I'm
attaching a patch to support mouse-wheel events in the illume keyboard.
For the patch to the xserver (haven't sent it upstream yet), see
http://lists.shr-project.org/pipermail/shr-devel/2009-July/000251.html
The new behavior is working very well for me, and I think this patch
should be included in the tree.
