Acutally I hope someone finds it easy.<br /><br />PROBLEM: My text editor project requires a custom undo/redo for Tkinter.Text. I put in the same string for both Test One and Test Two below, but undo does not act consistently due to a inconsistent column variable in KeyRelease event handler given by Tkinter. The problem seems to be that I type too fast for second test which produces a bad column value. Can you help me find the problem?<br /><br />TWO TEST PROCESS TO REPRODUCE THE ERROR:<br /><br />TEST ONE<br /><br /> Type this string slowly: 'one two three'<br /> Press F1 to see each word undo.<br /><br /> Result: Works fine. (For me atleast. Ephasis: type slowly.)<br /><br />TEST TWO<br /><br /> Type the same string as fast as you can: 'one two three'<br /> Press F1 to see each word undo.<br /><br /> Result: Gets the wrong column and does not undo properly. (Restart script and repeat this step if you don't see the error at first, it sometimes works fine with fast typing. I usually get it with 3 to 4 tries at the most.)<br /><br />QUESTION: Is this a bug in Tkinter, or am I not understanding something specific within Tkinter that would produce consistent columns for my undo/redo records?<br /><br /><br /><br />from Tkinter import *<br /><br />class TextView(Text):<br /><br /> def __init__(self, root):<br /> Text.__init__(self, root)<br /><br /> self.history = History(self)<br /> self.bind("<KeyRelease>", self.keyRelease)<br /><br /> # used to capture a char at a time in keyRelease.
