Using Tkinter in Python 2.7.
What I need is to be able to check regularly if the text in the widget has been changed. Ideally, I would have been able to call a function each time a change to the text was made or the widget was used, but this seems impossible.
More specifically, I want to be able to have a label change between "original", "altered", "empty" and "new". Where e.g....
22 results in 0.0047 seconds.

Pass text variables to Labels in Tkinker GUI?

Problems with redrawing tables
I am learning how to use tktable. I made a table and put some data in it which appeared. I want to put it into a loop and change the data 5 or 6 times. Right now I am just putting simple data in until I get it to work correctly, just to verify the tables is updated. Later I will put specific data.

Tk, OSX, PYTHON application menu override

There are allusions to a "special" apple menu keyword, but I've so... -

Linking certain filenames in a directory and a dictonary?
Hi. I'm trying to get my feet wet with programming and keep hitting some brick walls.
I basically want to look in a folder for certain filenames. If the files are there, I would like the term linked to the filename to be in a listbox.
