Liam, I am using IDLE - and Tkinter, John and Liam. I have been working
through the book "Python Programming" by Michael Dawson. One of his
programs calls for the entry of a password, then reveals a message. What I
would like to do is make the Text widget that reveals the message, unusable
by a user!
I tried the state = DISABLED in the 2nd line of code below, where the widget
to display the text is created - and it did disable the Text widget - to the
extent that it wouldn't reveal the message! I have tried multiple other
places to put the DISABLED - at the end of this code for instance, but it
doesn't seem to work there! Where can I place it so that it will prevent a
user access to that Text widget?
Also - assuming I can get it to work - what is the term I need to use to
enable to Text widget again so that it will continue to work the next time
around. I tried ENABLED - but was told that global name is not defined!
Any ideas? Thanks in advance for suggestions.
Diana
Here is the code:
# create text widget to display message
self.secret_txt = Text(self, width = 35, height = 5, wrap = WORD)
self.secret_txt.grid(row = 3, column = 0, columnspan = 2, sticky =
W)
def reveal(self):
""" Display message based on password. """
contents = self.pw_ent.get()
if contents == "secret":
message = "Here's the secret to living to 100: live to 99 " \
"and then be VERY careful."
else:
message = "That's not the correct password, so I can't share " \
"the secret with you."
self.secret_txt.delete(0.0, END)
self.secret_txt.insert(0.0, message)
