You can bind KeyRelease, etc. like such:
#! /usr/bin/env python
from Tkinter import *
from ScrolledText import ScrolledText
def format(t):
return t.replace('.','!')
def dobind(tin, tout):
def doit(e=None):
tout['state'] = NORMAL
tout.delete('1.0', END)
newtext = format(tin.get('1.0', END).strip())
tout.insert(END, newtext)
tout['state'] = DISABLED
return doit
def main():
tk = Tk()
textin = ScrolledText(tk)
textin.pack(expand=NO, fill=X)
textout = ScrolledText(tk)
textout['state'] = DISABLED
textout.pack(expand=NO, fill=BOTH)
textin.bind('<KeyRelease>', dobind(textin, textout))
tk.mainloop()
if __name__ == "__main__":
main()
Etc. includes copy and paste events with mouse.
