Does any one out there have an example of how to setup logging in Python to a Tkinter Text Widget? I have seen this used in several apps but cannot figure out how to direct

Building on ford's too but adding colored text !

class WidgetLogger(logging.Handler):
    def __init__(self, widget):
        logging.Handler.__init__(self)
        self.setLevel(logging.DEBUG)
        self.widget = widget
        self.widget.config(state='disabled')
        self.widget.tag_config("INFO", foreground="black")
        self.widget.tag_config("DEBUG", foreground="grey")
        self.widget.tag_config("WARNING", foreground="orange")
        self.widget.tag_config("ERROR", foreground="red")
        self.widget.tag_config("CRITICAL", foreground="red", underline=1)

        self.red = self.widget.tag_configure("red", foreground="red")
    def emit(self, record):
        self.widget.config(state='normal')
        # Append message (record) to the widget
        self.widget.insert(tk.END, self.format(record) + '\n', record.levelname)
        self.widget.see(tk.END)  # Scroll to the bottom
        self.widget.config(state='disabled') 
        self.widget.update() # Refresh the widget
