PyQt

What it is

PyQt provides Python developers with a comprehensive set of tools to create rich graphical user interfaces. It is built on top of the Qt library, enabling developers to build applications that run across multiple platforms without modification.

PyQt stands out by offering a robust set of tools and libraries specifically tailored to Python developers who need to build cross-platform desktop applications with rich graphical interfaces.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Steep learning curve for non-Python developers

   PyQt leverages Python-specific idioms and patterns which can be challenging for developers unfamiliar with the language.

2. 02

   Frequent breaking changes between versions

   Historical version updates have introduced significant API changes, requiring substantial refactoring of existing codebases.

3. 03

   Limited native support for modern Python features

   PyQt's integration with newer Python features such as type hints and asynchronous programming is not fully developed or supported.

4. 04

   Complex setup process, especially on Windows

   Setting up PyQt can be complicated due to dependency requirements and the need for specific configurations that are less intuitive on certain operating systems like Windows.

What it does well

• Cross-platform application development

• Comprehensive set of UI controls and widgets

• Signal-slot mechanism for event handling

• Supports Pythonic syntax and idioms
