From: "ing. Davide Rizzo" ####@####.#### Date: 27 Mar 2008 14:43:26 -0000 Message-Id: <47EBB28E.6050603@elpa.it> 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.

I'm running this on an embedded arm9-based CPU, equipped with QVGA lcd panel and touchscreen. After running the monolithic program, it's locked on a select (like it should). That select the first time waits not for a touchscreen event, but for a console key press, and then it "seems" to work. Afther this first event, in practice the program run in a short loop, never waiting on the select call. That debug was performed using h3600_tsraw touchscreen driver and kernel 2.6.23. The same program is actually running without problems in my system with kernel 2.6.24 and the standard event driver I gave you, with separated nano-X server and client program. I'm sorry, I tried this some months ago, so I don't remember more details. If you're interested in it, I can have again a deeper debug session to give you more details.
