Hello Monks! I humbly request your assistance.

I am just learning TK and I have not been able to find a comprehensive source of information (I'm planning on buying a book tomorrow).

Here's what I'm working on, I am desinging a script to act as a control panel which can monitor, start and stop certain scripts that I want running on my machine. I have gotten the raw gui designed, I have the start and stop buttons designed.

What I can't figure out is the monitor widget. I want a block/widget/button that will show red when a specific script is not running and green when the script is running. I can design a subroutine that can do a "ps -ef|grep" and determine if the script is running, but how do I have the little subroutine running all the time and updating the widget so that it gives a visual display of the background script's status?


THANX! for any help you can give! -Kevin
