GTK features and specs

  • Cross-Platform Compatibility
    GTK supports multiple platforms including Linux, Windows, and macOS, making it versatile for developing applications across different operating systems.
  • Rich Widget Set
    GTK provides a comprehensive set of widgets for GUIs, allowing developers to create complex and highly functional user interfaces.
  • Open Source
    Being open-source, GTK offers developers the ability to inspect, modify, and distribute their modifications, fostering a community of collaboration and innovation.
  • Language Bindings
    GTK supports multiple programming languages through various bindings, including C, Python, and JavaScript, thereby offering flexibility to developers.
  • Consistent Look and Feel
    GTK strives to maintain a consistent look and feel across applications and platforms, providing a unified user experience.

Possible disadvantages of GTK

  • Steep Learning Curve
    For beginners, GTK can present a steep learning curve due to its comprehensive nature and the depth of its APIs.
  • Performance Overhead
    GTK applications can sometimes exhibit performance issues, especially on less powerful hardware, due to the extensive features and capabilities it includes.
  • Limited Native Support on macOS
    Although GTK is cross-platform, native support and integration on macOS can be limited compared to its support on Linux and Windows.
  • Heavy Dependencies
    GTK applications often require a significant amount of dependencies, which can lead to larger application sizes and more complex installation processes.
  • Documentation Quality
    While GTK has extensive documentation, the quality and depth can sometimes be inconsistent, which may hinder learning and troubleshooting for developers.

Qt features and specs

  • Cross-Platform Development
    Qt allows developers to write applications that can run on multiple platforms, including Windows, macOS, Linux, Android, and iOS, without the need for significant code changes.
  • Rich Documentation
    Qt provides extensive and well-maintained documentation, making it easier for developers to learn and troubleshoot the framework.
  • Mature and Stable
    Being a mature framework, Qt has a long history of stability and a strong track record in producing robust applications.
  • Comprehensive UI Components
    Qt offers a wide range of built-in UI components, which can significantly speed up the development process and provide a native look and feel on different platforms.
  • Strong Community Support
    Qt has an active and helpful community, which can be beneficial for developers seeking support or looking to collaborate on projects.
  • Performance
    Applications built with Qt tend to be efficient and performant, due to close-to-the-metal coding options and optimizations available in the framework.
  • Tooling
    Qt Creator, the official IDE for Qt, offers powerful tools for designing, coding, testing, and debugging applications, enhancing productivity.

Possible disadvantages of Qt

  • Licensing Costs
    Though Qt offers an open-source option, commercial licenses can be expensive, which can be a significant constraint for smaller businesses or independent developers.
  • Learning Curve
    The framework can have a steep learning curve for beginners, especially for those unfamiliar with C++ or the specific paradigms Qt employs.
  • Large Executable Size
    Applications built with Qt can have larger executable sizes compared to those built with more lightweight frameworks, which might be a concern for some applications.
  • Dependency on C++
    While Qt has bindings for other languages like Python (PyQt, PySide), its core is based on C++, which might not be ideal for developers looking for a more modern or different programming language.
  • Complexity in Customization
    While Qt offers many features out-of-the-box, deep customization, especially for non-standard requirements, can become complex and time-consuming.
  • Build Times
    Due to its comprehensive nature, applications using Qt can have longer build times, which can slow down the development cycle.

Best GUI frameworks for Go
The go-gtk package is a Go binding for the GTK toolkit. The package enables Go developers to use the GTK library in Go with similar features as the GTK library. The package is performant, well-documented, and actively maintained. The go-gtk package depends on the GTK library to function, and you’ll need to have GTK installed on your machine to build GUI applications in Go....

    Wha? An example of a barebones GTK JavaScript app is right there on the front page. One click on the bindings link, will send you to the official GNOME-hosted GitLab repo for gjs, which in-turn, has links to official API documentation. Source: over 2 years ago
  • GTK 4 & JavaScript - how to start?
    I think what is lacking is a kind of introduction similar to what you have written in your post now. Myself, I am totally new to GTK. I come as a user of Gnome. All I knew until today was that to develop applications for Gnome, preferably I should use something called GTK. And I heard so much about the recent version that came out - GTK 4. So I started to look for a Getting Started tutorial for GTK 4, to build... Source: about 3 years ago
  • GTK 4 & JavaScript - how to start?
    BTW, I think the GTK team should really step up their game in terms of how to encourage new people into their ecosystem. Seeing that windows screenshot in the official tutorial makes me think I'm dealing with some old technology. Also, the official gtk.org has two separate tutorials that show very similar applications being built. Source: about 3 years ago
