r67240 - sandbox/trunk/tkinter-polo/src/Dialog.py
|
|
Author: guilherme.polo
Date: Mon Nov 17 01:14:07 2008
New Revision: 67240
Log:
Dropped usage of star import;
No need to check for TkVersion <= 3.6 since _tkinter enforces the need for
Tcl/Tk 8.2 at least;
Cleaned up the Dialog class;
Correctly converts the reply to an integer, checking for the possibility of
receiving a tuple;
Updated example to suggest the more appropriate use of the Dialog.
