gtk-fortran
A GTK / Fortran binding enabling scientists to build cross-platform graphical user interfaces (GUIs) in Fortran.
What is gtk-fortran?
gtk-fortran is a GTK binding written entirely in Fortran that enables developers to build cross-platform graphical user interfaces (GUIs) using the Fortran programming language. It leverages the C/Fortran interoperability features introduced in the Fortran 2003 standard to provide a partial GTK binding specifically designed for scientific programmers who need to create GUI applications.
Scientists and researchers programming in Fortran who need to build graphical user interfaces for their applications, particularly those in scientific computing fields requiring cross-platform GUI solutions.
Developers choose gtk-fortran because it provides a pure Fortran implementation of GTK bindings, eliminating the need for mixed-language programming while offering cross-platform GUI capabilities specifically tailored for the scientific Fortran community.
Overview
A GTK / Fortran binding, and its documentation (in the Wiki tab).
Use Cases
Best For
- Building scientific visualization tools with Fortran backends
- Creating cross-platform GUI applications in Fortran
- Developing research software with graphical interfaces
- Adding modern GUI capabilities to legacy Fortran codebases
- Scientific computing applications requiring user interaction
- Educational tools for teaching Fortran with graphical components
Not Ideal For
- Projects requiring rapid GUI prototyping with drag-and-drop builders or modern web frameworks
- Teams developing mobile or web applications instead of desktop-only interfaces
- Applications needing extensive third-party integrations or plugins common in languages like Python or JavaScript
- Environments where GTK library dependencies are difficult to install or manage cross-platform
Pros & Cons
Pros
Leverages Fortran 2003 C interoperability for a 100% Fortran binding, eliminating mixed-language hurdles and simplifying integration with existing scientific codebases.
Targets the latest GTK library, providing access to contemporary GUI features and ensuring cross-platform compatibility for desktop applications on Linux, Windows, and macOS.
Specifically designed for scientists and researchers, bridging high-performance Fortran backends with graphical interfaces for data visualization and user interaction.
Enables building GUI applications that work across different operating systems, leveraging GTK's portability for broad deployment in research environments.
Cons
As admitted in the README, it's only a partial GTK binding, meaning some advanced widgets or features may be missing or incomplete compared to full GTK implementations.
Requires detailed setup steps with dependencies like GTK libraries, which can be cumbersome, especially on non-Linux systems, as highlighted in the wiki instructions.
Being Fortran-centric, it has a smaller community and fewer resources—such as tutorials or third-party tools—compared to mainstream GUI frameworks, limiting development agility.
