�Zd�Zd�Zd�Zd�Zd�ZRS(s�Support for redirecting arbitrary widget subcommands.

    Some Tk operations don't normally pass through Tkinter.  For example, if a
    character is inserted into a Text widget by pressing a key, a default Tk
    binding to the widget's 'insert' operation is activated, and the Tk library
    processes the insert without calling back into Tkinter.

    Although a binding to <Key> could be made via Tkinter, what we really want
    to do is to hook the Tk 'insert' operation itself.

    When a widget is instantiated, a Tcl command is created whose name is the
    same as the pathname widget._w.  This command is used to invoke the various
    widget operations, e.g. insert (for a Text widget). We are going to hook
    this command and provide a facility ('register') to intercept the widget
    operation.

    In IDLE, the function being registered provides access to the top of a
    Percolator chain.  At the bottom of the chain is a call to the original
    Tk widget operation.

SXdS(sCallback from Tcl which runs when the widget is referenced.

        If an operation has been registered in self._operations, apply the
        associated function to the args passed into Tcl. Otherwise, pass the
        operation through to Tk via the original Tcl function.

        Note that if a registered function is called, the operation is not
        passed through to Tk.  Apply the function returned by self.register()
        to *args to accomplish that.  For an example, see ColorDelegator.py.
