Selection demo

Here is sample code to illustrate


import sys
from Tkinter import *
mle = None
def main():
	global text1
	root = Tk()
	qbutton = Button(root)
	qbutton['text'] = 'quit'
	qbutton['command'] = quit_callback
	qbutton.pack()
	sbutton = Button(root)
	sbutton['text'] = 'show selection'
	sbutton['command'] = show_callback
	sbutton.pack()
	text1 = Text(root)
	text1.pack()
	
	root.mainloop()
def quit_callback():
	sys.exit(0)

def show_callback():
	global text1
	ranges = text1.tag_ranges(SEL)
	start = ranges[0]	
	stop = ranges[1]
	print repr(text1.get(start, stop))
main()

The word SEL refers to the current selection and this is in fact associated with a tag. I used the "Introduction to TKinter" on www.pythonware.com/library/tkinter/introduction to find out.
