Adding a progressbar to the GUI

In this recipe, we will add a Progressbar to our GUI. It is very easy to add a ttk.Progressbar, and we will demonstrate how to start and stop a Progressbar. This recipe will also show you how to delay the stopping of a Progressbar and how to run it in a loop.

Note

Progressbar is typically used to show the current status of a long-running process. 

Getting ready

We will add the progressbar to Tab 2 of the GUI that we developed in the previous recipe: Creating tooltips using Python.

How to do it…

We then place a ttk.Progressbar widget below all other widgets on Tab 2 and align this new widget with the other widgets.

Our GUI now looks as follows:

GUI_progressbar.py

We connect each of our four new buttons to a new callback function, which we assign to their command property:

Clicking the Run Progressbar button will run...
