The core pointer can have no more than five buttons, and only X and Y movement. The core keyboard can have up to 247 (or 248) keys. These are hard limits imposed by the client/server communcation protocol. The XInput extension extends considerably what sort of events an input device can generate, but of course for a client to use them it must be XInput-aware. >Randall has done the hard part which is decoding the mouse events >from the X10 Remote Mouse since Randall wrote the decoding routine >I am sure he can elaborate on the protocol. If you are interested >in following the code it is available in -current's moused.c or >if you like I can mail you moused.c To be honest, I don't have the time to be interested in the details at the moment. I was just suggesting that if you want to deal with this using X events it might be worth taking a look at the XInput extension to see if it will allow the sort of things you want (and I don't really know if it will or not). XFree86 3.3.2 does have some XInput device support currently for some tablets, a touch screen and a joystick. The XFree86 mouse code is currently maintained by Kazutaka Yokata (who was already on the CC list). If XInput looks like it might be useful and you want to follow it up, I can put you in touch with one of the people who maintains our XInput support.
