Overview

Why does this project exist?

The purpose of this project is create a set of beautifully designed and easy to apply styles for your tkinter applications. Ttk can be very time-consuming to style if you are just a casual user. This project takes the pain out of getting a modern look and feel so that you can focus on designing your application. This project was created to harness the power of ttk’s (and thus Python’s) existing built-in theme engine to create modern and professional-looking user interfaces which are inspired by, and in many cases, whole-sale rip-off’s of the themes found on Bootswatch. Even better, you have the abilty to create and use your own custom themes using TTK Creator.

A bootstrap approach to style

Many people are familiar with bootstrap for web developement. It comes pre-packaged with built-in css style classes that provide a professional and consistent api for quick development. I took a similar approach with this project by pre-defining styles for nearly all ttk widgets. This makes is very easy to apply the theme colors to various widgets by using style declarations. If you want a button in the secondary theme color, simply apply the secondary.TButton style to the button. Want a blue outlined button? Apply the info.Outline.TButton style to the button.

What about the old tkinter widgets?

Some of the ttk widgets utilize existing tkinter widgets. For example: there is a tkinter popdown list in the ttk.Combobox and a legacy tkinter widget inside the ttk.OptionMenu. To make sure these widgets didn’t stick out like a sore thumb, I created a StyleTK class to apply the same color and style to these legacy widgets. While these legacy widgets are not necessarily intended to be used (and will probably not look as nice as the ttk versions when they exist), they are available if needed, and shouldn’t look completely out-of-place in your ttkbootstrap themed application. Check out this example to see for yourself.
