X11R2, Sun 3/280 running 3.5, X toolkit.

I'm trying to convert some applications from X10 to X11,
and have run into a problem. Under X10, I could register
an event handler with a window: I would open a window,
make a button box and some command buttons, and I could
get events either through the command buttons or directly
from the window (button clicks or key presses). However,
as far as I can tell, there is no way to register an event
handler with a window under X11. Am I missing something?
I'm trying to avoid writing a special widget, because I
have a fair amount of code that assumes a window.

If I can't register an event handler, is there a way to use
routines like XDrawLine, etc, with a widget? I've tried to
get the associated window using XtWindow, but when I try to
get the attributes of that window, I get an error.
