After 1/2 hour working with it i have the following feelings: * using a pen is WAY more convenient than a mouse and buttons for menu selection etc. And for drawing there is absolutely no comparison. * i think a few buttons on the stylus would be extremely convenient to use. My unit has only one button (the tip) and one near the pad. I am mapping the tip as button 1, which is ok for most things, but double-click etc. are not very easy. Plus, when you put back the stylus, the cursor follows you... * In many occasions, i really miss the ability to map the whole tablet (or a fraction) within a window, so i don't have to "imagine" the boundaries of the working area while drawing. In order to do this, however, i do need two things: + absolute coordinates + feedback from the server on the window's geometry Any idea on how to improve moused communication with its consumers (the X server, or syscons) ? cheers luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
