CustomTkinter

Despite the latest advancements in terms of processing power that the world of PC components has made so far, many users still prefer to avoid bloating their machines with extra utilities requiring unreasonably high amounts of RAM to function properly, with an example being the demanding Electron app framework.

As such, developers who seek out a lighter alternative can combine the flexibility of the Python programming language with an elegant and highly adaptable library of graphical user interface widgets known as CustomTkinter, to avoid relying on terminal-based commands that may otherwise feel daunting to inexperienced users.

Upon downloading the source code, developers are greeted to a selection of examples of interactive widgets showcasing the animation, smoothness and design language of the framework to provide potentially interested programmers with a taste of the available options before commencing the implementation phase. For instance, the rounded corners of most visual items will fit in with Windows’ latest iteration of the Fluent Design language, while the option of a dynamic dark mode that also follows the system theme can provide users with a more comfortable nighttime usage experience.

Accessibility remains an integral part of any software’s usage experience, which is why the library also includes support for selectable UI scaling to make the layout more palatable to those with lower visual acuity, while also paving the way towards an interface compatible with touchscreen interaction. The modern design components do not skimp on the usual desktop-class details, given how buttons change their color when hovered on using the cursor, letting you know which options can be activated and which are disabled.

Text-boxes with excess information have a built-in scroll bar for developers who wish to include their program’s license in the “About” section of their app without taking up too much screen space. Smooth and precise sliders alongside seek-bars with varying snap-on steps can be useful for designing screen brightness dimmers, multi-device volume adjusters or video scrolling when fast-forwarding or rewinding content. Finally, on top of being able to implement icons next to buttons’ text labels as visual cues, the framework allows the use of vertical tabs in sidebars for a clear separation of menus.

If you are a developer on the lookout for a sizable framework to implement in your UI-equipped Python-based projects, then CustomTkinter may be the right choice given its exhaustive documentation and support for varying features to match the functionality of the utility you are currently working on.
