Custom2kinter documentation

Custom2kinter is a Python UI library based on Tkinter, which provides new, modern, and fully customizable widgets. They are created and used like normal Tkinter widgets and can also be used in combination with normal Tkinter elements.

The widgets and the window colors either adapt to the system appearance or the manually set mode (light/dark). They also support HighDPI scaling (on Windows and macOS).

With Custom2kinter you’ll get a consistent and modern look across all desktop platforms (Windows, macOS, Linux):

Application example

This project was created to continue the development of CustomTkinter, since the original author lost interest in it. The first release of this library is v5.3.0, which continues the old numbering, and it is fully compatible with the last released version of the original library. They can’t live together in the same environment, so be sure to uninstall customtkinter before installing custom2kinter. This library is still imported using the original name, so existing code doesn’t need to be updated.

This is the official Custom2kinter documentation, but it will use “CustomTkinter” as the name of the library. It is also written with the assumption that the developer already knows how tkinter works, so basic concepts are not explained, and it links to other resources that explain them.
