I'm re-working the CVSed Java files "in my own image", so that I can actually do some testing. Also, I've cut-n-paste out the java.awt.KeyEvent into jos.system.event.KeyEvent to make a clone of it. In my view that makes us a bit more stable than depending on a bunch of awt stuff, which has no place in the kernel. > > As you can probably tell from looking at the source, > jos/platform/driver should contain the software that converts from the > hardware (i.e. jos.system.KeyEvent events generated by the > jos.system.keyboard abstraction -- which, perhaps, should be moved to the > driver class?) into the JOS platform (i.e. the virtualized hardware used > to interface w/ the O/S).

I'll try that out in my mucking around. -Matt _______________________________________________ Kernel maillist - [EMAIL PROTECTED] http://jos.org/mailman/listinfo/kernel
