This tabbed interface is very useful for Tkinter users. I am sure there is a better way to do it, but I did the best I could.

Please enjoy this tabbed interface by SunjayVarma - www.sunjay-varma.com

UPDATES: Fixed the index issues. Made it easier to use.

__doc__ = info = '''
This script was written by Sunjay Varma - www.sunjay-varma.com

This script has two main classes:
Tab - Basic tab used by TabBar for main functionality
TabBar - The tab bar that is placed above tab bodies (Tabs)

It uses a pretty basic structure:
root
-->TabBar(root, init_name) (For switching tabs)
-->Tab    (Place holder for content)
	\t-->content (content of the tab; parent=Tab)
-->Tab    (Place holder for content)
	\t-->content (content of the tab; parent=Tab)
-->Tab    (Place holder for content)
	\t-->content (content of the tab; parent=Tab)
etc.

Just run it once to see a demo of its use.

It would be great if you could tell me what you don't like, instead of just rating down.

Hey Sunjay, this is very cool. One issue I had when I tried it out: When you resize the window all the widgets on each tab are stuck to the bottom of the window. I'm very new to Tkinter, so far I haven't been able to figure out what's causing it. Do you know which line, is causing this, or what code needs to be added to change this? I'd rather the widgets be anchored to the NW corner of each tab.
