from __future__ import print_function

class WidgetRedirector:
    """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.  For one thing, we want
    a text.insert call in idle code to have the same effect as a key press.

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.  We will also intercept method calls on the Tkinter class
    instance that represents the tk widget.

In IDLE, WidgetRedirector is used in Percolator to intercept Text
    commands.  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.
