> That looks pretty good. Just be sure to check the Keymap preflet code
before you try to implement keymap support, as I suspect that will have
most of what you would need (as Axel suggested.)
BeAPI already has function ''get_key_map'' for handling keymaps. This
function is enough for keyboard. I wrote special class "KeyboardHandler"
that gets scancodes and produces messages. Also it handles states of caps,
num and scroll lock keys, keystroke repeating by separate thread. For now
handling deadkeys is missing. Keymap handling is a little part of this
class. Most part is message generation that duplicates hardware keyboard
input_server device.

> Looks nice, patches welcome. However, I think it must share the same
code (KeyboardView) that Keymap is using -- it does not make much sense to
maintain code that pretty much does the same thing in two different
places.
At first KeyboardView in Keymap preflet is hardcoded to be keymap editor
and not keyboard. It need to be changed a lot to be shared. Changing will
be more complicated than writing independent implementation. Current
Keymap preflet is also waste a lot of CPU time that is a problem for
mobile devices.
At second I plan to use different keyboard layout format that layout keys
like layouting of BViews using BLayout and had ability to use special keys
such as keys without scancode (smiley, special characters), and keys that
change layout or keymap. Also I plan to make GUI editor for layout to take
benefit of modifiable nature of onscreen keyboard unlike hardware
keyboard.
