Agar is an open-source,
cross-platform toolkit for graphical
applications.
The Agar GUI takes maximum advantage of hardware graphics acceleration
when it is available, but it also supports plain framebuffer interfaces
such as direct video via
SDL.
When a window system is not available, Agar can even provide its own.
Agar consists of two libraries:
Agar-Core provides generic object functions and
portability interfaces.
Agar-GUI includes the base GUI system and a comprehensive
set of standard widgets.
Both are implemented in C, but are usable from other languages. When
compiled with threads support, both libraries are efficiently thread-safe.
The distribution also includes some more specialized libraries aimed at
specific applications.
Agar is free software. Its source code is freely usable and re-usable by
everyone under a BSD license, which allows
use in commercial applications free of charge.
Agar is stable, well-maintained and has been growing organically since
early 2002.
The Agar project is sponsored by
Csoft.net:
Security conscious, high-availability Unix hosting on redundant
server arrays.

The Agar GUI library is designed to work under almost any platform that
provides a graphic display and some kind of input device.
Currently, there are drivers for
SDL and
OpenGL.
The OpenGL mode makes efficient use of hardware acceleration.
The API is simple, object-oriented and unobtrusive (e.g.,
bindings reduce the need for event
handlers to the minimum).
Implementing new widgets as part of an application or library is easy,
and the Agar object system provides you with inheritance, even if you are
only using C.
See the Agar FAQ for more details.

Other libraries using Agar |
|
|
A portable and efficient 3D engine with an emphasis on generality.
It also provides a visualization widgets, an efficient math library,
computational geometry routines, dimensioned 2D sketches and geometrical
constraint solving.

|
|
|
A simple 2D vector graphics package which allows developers to specify
hierarchical sketches consisting of elements such as lines, curves and
text. It was designed mainly for editors (for example, the circuit editor
in agar-eda uses it).
For dimensioned/constrained technical drawings, the SK library
(in FreeSG) is recommended instead.

|
|
|
A library for generating and manipulating feature-based pixmap
elements (either static or animated). It uses an image format which allows
directives, transformations and instancing of graphical elements.

|
|
|
This is a 2D tiling library aimed at isometric/platform games and scrollers.
Agar-MAP includes a visualisation widget and a complete editor.
Along with
Agar-RG,
it provides built-in bitmap edition.

We expect to make the first release of the Agar-1.4 series in June 2008.
The focus of the new series is the addition of drivers with multiple
window support (e.g., X11, Cocoa and Win32), the implementation of a
graphical GUI editor, support for high-level GUI operation over the
network and improved desktop integration
(see the full list).
The Agar-1.4 branch is available in /branches/agar14 on Subversion
