[Idle-dev] Extension to handle Cancel

I'm working on a plugin extension for IDLE that can run a test when
Control+C is pressed. Unfortunately, Control+C (or <Cancel> in Tkinter
bindings) is not handled as other key bindings are. Instead there is a
cancel_callback in the pyshell instance that is called.
So, I've tried to replace the cancel_callback method from inside the
extension (I have a working version from an external main---but it is
really hacky). However, it looks like editwin.flist.pyshell doesn't
exist yet when the constructor of the extension is called.
Is there any way for my extension module to have some code that gets
called after the pyshell has been created?
def __init__(self, editwin):
# works for other windows, after the shell is made, but:
print editwin.flist.pyshell.cancel_callback, "does not exist yet"
# when constructed for the shell
