We chose a slightly convoluted solution: use Java for the GUI -- we
already had a Java app to do GUI stuff. I adapted and upgraded MiKa
(formerly Wonka) to suit my needs. It has an AWT implementation that
integrates quite nicely w/ the eCos framebuffer, and it has itself
implemented fonts, shapes, widgets, etc etc. This MiKa JVM is spawned
from the eCos C application. Like your microwindows port, the JVM seems
to need a network stack.
However, all this is much work in progress, and it runs as a kind of
background task in my work schedule -- other stuff crops up (with
appearing hardware) that requires attention immediately. Thus, there are
many aspects that are unimplemented, for example, shutting down the JVM;
in fact, right now the JVM kills the eCos application at exit time,
which won't be terribly hard to fix but I live easily w/ it right now.
Needless to say, this will make your application memory- and CPU-hungry
(interpreter without JIT compiler, bunches of threads for small tasks
like timeouts etc).
Anyway, our repository is public. If you are interested in giving it a
try, or even in cooperating, let me know.
