I got it!!! Yup, I am sure it can be optimized but it works!!!
Hmmm ... it doesn't work for me ...

How *could* this work, Dave, since you call function new_Rword() before
you define it? I rearranged the statements in your program, and it now
works for me:
#---------------------------------------------
from Tkinter import *
import re
redList = "red dog".split()
blueList = "blue ball".split()
greenList = "green grass".split()
def get_position(event):
complete = Tbox.get("1.0", END)
for word in redList:
new_Rword(complete, word)
for word in blueList:
new_Bword(complete, word)
for word in greenList:
new_Gword(complete, word)
def new_Rword(complete, word):
Tbox.tag_remove(word, "1.0", END)
for matchobj in re.finditer(word, complete):
start,end = matchobj.span()
Tbox.tag_add("red", "1.0 + %d chars" % start,"1.0 + %d chars" %
end)
def new_Bword(complete, word):
Tbox.tag_remove(word, "1.0", END)
for matchobj in re.finditer(word, complete):
start,end = matchobj.span()
Tbox.tag_add("blue", "1.0 + %d chars" % start,"1.0 + %d chars"
% end)
def new_Gword(complete, word):
Tbox.tag_remove(word, "1.0", END)
for matchobj in re.finditer(word, complete):
start,end = matchobj.span()
Tbox.tag_add("green", "1.0 + %d chars" % start,"1.0 + %d chars"
% end)
root = Tk()
Tbox = Text(root, width=40, height=15, wrap=CHAR,
font="Times 14 bold", bg="#dddddd")
Tbox.tag_config("red", foreground="red")
Tbox.tag_config("blue", foreground="blue")
Tbox.tag_config("green", foreground="green")
Tbox.pack()
Tbox.bind("<KeyRelease>", get_position)
Tbox.focus()
root.mainloop()
#---------------------------------------------
This version also has the advantage of defining each function just once,
instead of multiple times on each keystroke! Still to-do:
* rename get_position() to get_complete_text()
* replace new_Rword(), new_Bword(), and new_Gword() with a single
function that has an extra parameter, "color".
Keep at it!
