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.

JavaFX features and specs

  • Rich UI Controls
    JavaFX provides a wide range of built-in UI controls, such as buttons, tables, and charts, which makes it easy to create complex user interfaces.
  • FXML Support
    JavaFX allows developers to use FXML, a scripting interface that enables them to design user interfaces with XML, separating the logic from design, enhancing maintainability.
  • CSS Styling
    The framework supports CSS for styling UI components, offering flexibility in design and the ability to create visually appealing applications.
  • Scene Graph
    JavaFX's scene graph provides a hierarchical structure for managing the layout, simplifying the development of complex UIs with animations and transformations.
  • Cross-Platform
    JavaFX applications are cross-platform, allowing developers to run the same application on different operating systems without modifications.
  • Integration with Java
    As a part of the Java ecosystem, JavaFX integrates seamlessly with existing Java libraries and tools, benefiting from Java's robust environment.

Possible disadvantages of JavaFX

  • Steeper Learning Curve
    Despite its powerful features, JavaFX can be challenging to learn for beginners, especially those not familiar with Java.
  • Limited Third-Party Libraries
    Compared to other UI frameworks like Swing or frameworks outside of Java, JavaFX has a relatively smaller ecosystem of third-party libraries and tools.
  • Performance Issues
    JavaFX might face performance challenges, particularly when dealing with resource-intensive applications or those requiring very high responsiveness.
  • Mobile Support Limitations
    JavaFX's support for mobile platforms is not as strong as other frameworks, requiring additional tools or platforms like Gluon for mobile development.
  • Market Adoption
    The adoption of JavaFX in the industry is not as widespread as other technologies like React or Angular, which might influence community support and development resources.

25 Python Frameworks to Master
PyQt is one of the most popular sets of Python bindings for the Qt cross-platform application framework. This framework perfectly combines the simplicity of Python as a general-purpose language and the powerful Qt application framework built in C++.

Which Python GUI library should you use? Comparing the Python GUI libraries available in 2023
Before the Qt Company (under Nokia) released the officially supported PySide library in 2009, Riverbank Computing had released PyQt in 1998. The main difference between these two libraries is in licensing. The free-to-use version of PyQt is licensed under GNU General Public License (GPL) v3 but PySide is licensed under GNU Lesser General Public License (LGPL). This means...

  • 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
  • what would be the best looking GUI framework to develop a desktop python application? (other than Tkinter)
    If none of those are to your liking, you can use PyQT (or Pyside) but the learning curve is much steeper. Source: about 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

  • JBang, the missing scripting tool of the Java ecosystem
    JavaFX is a desktop and UI framework. Its official website is openjfx.io and is also supported by Gluon which provides additional UI components and brings mobile app support to JavaFX. JBang supports this frameowrk and can be used to create signle file JavaFX applications. - Source: dev.to / 4 months ago

  • Book review - Frontend Development with JavaFX and Kotlin
    Other topics handled in this chapter are Kotlin utilities for JavaFX and direct downloads of JavaFX releases from openjfx.io. The author also explains why FXML is not used in the book. I agree with his view that the XML files are not as dynamic as code and bring a mix of technologies into your project. - Source: dev.to / 12 months ago
  • Setting up Continuous Integration
    One, I don't understand Java environments really well. All I have done so far is create some GUI applications using JavaFX. Wish I could share my code, but unfortunately, its part of my assignments and can't be open-sourced. Second, the instructions I found in the Contributing docs were bare-minimum, and kinda hard to follow for a beginner. An experienced Java developer would get them really quickly, no doubt... - Source: dev.to / over 1 year ago
