Hi Greg,
I appreciate very much nano-X and nxlib. Currently I'm using them with
fltk 1.1.7.
Until now I used it on my Linux-ARM embedded system, with h3600-tsraw
touchscreen driver.
Unfortunately from linux kernel 2.6.24 that driver disappeared.
I added one driver to microwindows to use /dev/input/event0 standard
interface. I tested also with nxcal, it seems to work.
This should enable nano-X to work with various standard touchscreen drivers.
I enclose my patch to add that driver, plus some minor bug corrections
(I think).
I enclose also a very small nxlib patch that corrects an obsoleted
include and disables an annoying debug print (never used a FLTK clock
widget ?)
These patches have been generated with diff related to your actual cvs
version.
Please let me know if they can be useful.
Note: if you cannot reach the included patches, you can download them
from: http://www.elpa.it/eng/rd129.html
Question: Is it possible to use Fltk+Nxlib+NanoX with
linked-app-into-server option ? I tried, but without success.
Regards
