Open Source Ada User Interface (UI) Software

Agar provides a base GUI framework and a standard set of widgets from which graphical applications can be built which run natively under X11, Windows, MacOS, SDL and others. It takes advantage of texture and GPU acceleration wherever available. Agar can also attach to an existing framebuffer, SDL or OpenGL context and operate as a self-contained window-manager. It includes a standard library of general-purpose widgets, and is also designed to be extended externally. New widgets can be implemented as part of an application or library. Complex user interface elements can be realized often in few lines of code. Agar is also extensible at the low-level. The low-level API is documented such that modular drivers can be written which enable Agar applications to work seamlessly under many platforms graphics systems without any change at the application level.

The GNAVI project provides GWindows, a Rapid Application Development framework for Graphical User Interfaces on MS Windows. The durable Open Source answer to Delphi and Visual Basic. Alire crate: https://alire.ada.dev/crates/gwindows Mirror: https://github.com/zertovitch/gwindows

This project contains various examples, ported from Qt4 C++ to Ada language

Ada Fonts is a minimalistic example of using freetype fonts in OpenGL Ada applications using Felix Krause's FreeTypeAda package It is intended to be the modern version of the "glut font" demos from a previous era. It also uses Stephen Sangwine's PNG-IO package, and thin bindings to OpenGL, SDL2. More importantly, it shows how to encapsulate the scripts and runtime libraries necessary to easily compile and run on any computer running Windows, OS-X, or GNU/Linux. The only 3rd-party tool required is an Ada compiler.

Smart_Arguments is designed to simplify the use of command line arguments. The built in Ada facilities for command line argument processing are very basic. This package provide a higher level facility for dealing with command lines.

Xt/Motif bindings for Ada with GUI designer.

Gnoga uses modern web technologies to allow simple creation of cross platform GUIs for Ada with native or custom look and feels that perform on par to native toolsets locally and can be easily and securely remoted as web apps over the internet as well.
