Python 3 - tkinter (Tk Widgets) - BusyBar Busy Indicator

Here is another example GUI application using Python 3.1.

For this example, I used, a module for creating a "busy indicator" (like the knight-rider light). To do this, I first had to port BusyBar to Python 3.1 from 2.x. The new code for this module can be found here:

It renders on Ubuntu (with Gnome) like this:


#!/usr/bin/env python
# Python 3

import tkinter
from tkinter import ttk
import BusyBar

class Application:
    def __init__(self, root):
        self.root = root
        self.root.title('BusyBar Demo')
        ttk.Frame(self.root, width=300, height=100).pack()
        bb = BusyBar.BusyBar(self.root, width=200), y=20)

if __name__ == '__main__':
    root = tkinter.Tk()

Corey, there is a ttk themed widget which does this for you. It is the Progressbar widget and has two modes, determinate for when you can measure how close the process is to completion and indeterminate which just shows that things are still happening. Have you tried it for this application?

thanks for the heads up about ttk Progressbar! I didn't realize it had an indeterminate mode. I will definitely try it out.
