PyQt features and specs

  • Comprehensive UI library
    PyQt provides a wide range of UI components, from basic widgets to advanced tools. This allows for the creation of highly sophisticated interfaces.
  • Cross-platform
    Applications built with PyQt can run on different operating systems such as Windows, macOS, and Linux without requiring significant changes in the code.
  • Integration with Qt Designer
    Developers can use Qt Designer to design and implement their UIs visually, which can then be seamlessly integrated with Python code in PyQt.
  • Powerful event handling
    PyQt includes a highly efficient event handling system that makes it easy to manage user interactions and system events.
  • Good documentation and community support
    PyQt is well-documented, and there's a large community of developers who can provide support and share resources.
  • Python-specific advantages
    Leveraging Python's simplicity and readability, PyQt allows for rapid development and easy maintenance of applications.

Possible disadvantages of PyQt

  • License considerations
    PyQt is available under the GPL and a commercial license. If you want to create proprietary software without open-sourcing your code, you need to purchase a commercial license.
  • Steep learning curve
    While PyQt is powerful, it can have a steep learning curve for newcomers, particularly those who are not familiar with Qt and its paradigms.
  • Performance overhead
    Being a binding for Qt, some operations may have extra overhead compared to native Qt applications written in C++.
  • Dependency on external libraries
    PyQt relies on the Qt library, which means that you have to manage and distribute these dependencies along with your application.
  • Large binary sizes
    Applications created with PyQt can result in relatively large binary sizes because of the included Qt binaries.
  • Fragmentation of tools
    There can be fragmentation concerns, as PyQt must stay in sync with Qt, and different versions of Qt may introduce changes that are not immediately reflected in PyQt.

Quasar Framework features and specs

  • Versatile UI Components
    Quasar provides a rich set of UI components that are highly customizable and can be used to build responsive and highly interactive web, mobile, and desktop applications.
  • Cross-Platform Development
    Quasar is designed to facilitate the development of cross-platform applications, allowing developers to write a single codebase that can be deployed to web, mobile (via Cordova or Capacitor), and desktop (via Electron) environments.
  • Performance Optimization
    Quasar comes with built-in performance optimizations such as lazy loading, code splitting, and tree shaking, ensuring that applications run efficiently on multiple platforms.
  • Developer-Friendly
    Quasar offers a great developer experience with comprehensive documentation, active community support, and a set of powerful CLI tools for fast development and easy project management.
  • Integrated State Management
    Quasar seamlessly integrates with Vuex for state management, making it straightforward to manage application state in a scalable and maintainable way.

Possible disadvantages of Quasar Framework

  • Steep Learning Curve
    New developers or those unfamiliar with Vue.js may find Quasar's extensive toolkit and unique features overwhelming, leading to a steeper learning curve compared to more straightforward frameworks.
  • Large Bundle Size
    Despite its performance optimizations, the comprehensive nature of Quasar can sometimes result in larger bundle sizes, which may impact load times, especially for applications with extensive functionality.
  • Dependency on Vue.js
    Quasar is heavily tied to the Vue.js ecosystem. This means that developers must be proficient in Vue.js to fully leverage Quasar's capabilities, potentially limiting its adoption by teams preferring other JavaScript frameworks.
  • Mobile Performance
    While Quasar supports mobile development, performance can vary depending on the specifics of the project and target platform, potentially requiring additional optimization for a seamless user experience.
  • Community and Ecosystem
    Quasar's community and ecosystem, while growing, are still not as large or mature as those of other more established frameworks like React or Angular, which may result in fewer third-party plugins and shared resources.

  • Python vs. JavaScript: Is It a Fair Comparison?
    JavaScript is a clear winner in the category of mobile development. There are some niche frameworks to do mobile development with Python—like Kivy and PyQT—but pretty much nobody uses them. - Source: dev.to / almost 3 years ago

  • Is there a "Windows Forms" GUI designer for Python?
    Also, there is the PyQt module which is a comprehensive set of Python bindings for the Qt GUI. It has Qt Designer. Source: over 3 years ago
  • Best way to install qutebrowser?
    As for PyQt, that's developed entirely independently from Qt (by Riverbank Computing). The major/minor versions usually line up with the respective Qt releases (since the Qt release introduces new APIs, so a new PyQt release is needed to expose those to Python). However, it's versioned independently, and a new patch release of PyQt might be needed before/without Qt releasing a new patch release. For more details,... Source: about 4 years ago
