Dear alex:
  I wanna to add a hotbutton control to nanowm for my
pda(linux-vr).I'm new to win-mw,and there is so few 
docs about this. So I have to glance my eye at the
codes in /demos/nanowm and /nanox/ .  
  At beginning,I try to find out how I can add a
hotbutton event to the nano-X's events ,but I find 
that the most event is come from the Mouse and
Keyboard
it seems not easy to add a new type of events .
  Then  I try to got windows message from nanowm and 
save it in my apps ,when the hotbutton message coming 
this apps send command to nanowm.
  Follow is my test in this way.
1.in nanowm.c ,first make two named-pipe ,after 
 "switch" events read pipe for hotbutton message
 the message is forcedly switch to (GR_WINDOW_ID)
 and I try GrMapWindow(mywin_id);
2. in clients.c ,new_client_window() after  create
container window write the window->wid to the pipe

I can read from pipe wid "3" "5" ....
but when I send "5" to the pipe the nano-X broken
here is some error message:
nanowm: error 2

it seems that I made a silly mistake.
Any good ideas about this? and any doog docs can 
lead me to window-manage? I like a blind man in wm.

Best Regards
