    Eagle Mode

    Eagle Mode

    Zoomable user interface (ZUI) with file manager, file viewers and more

    Eagle Mode is a zoomable user interface (ZUI) with file manager, file viewers, games, and more. This project is about a futuristic style of human-computer interaction, where the user can visit almost everything simply by zooming in. It features a portable C++ toolkit API for developing such ZUIs, and it features the Eagle Mode application, which provides a virtual cosmos with plugin applications. The most important one is the professional file manager with its rich, scriptable command set. It integrates file viewers for most of the common file types, as well as an audio and video player. Furthermore, the virtual cosmos contains a chess game, a netwalk game, a 3D minesweeper game, a multi-function clock, a stock watchlist, some fractals, and a Linux kernel configurator in form of a kernel patch.

    Agar

    Agar

    Cross Platform GUI Toolkit

    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.

    HyperGUI

    HyperGUI

    A GUI based on libSDL for C++ applications

    HyperGUI is a library of C++ classes and some other parts which can draw and run a GUI for your application. It uses libSDL as its backend for graphical output. This library can be used in both dynamic multimedia (game), and standard (static) applications. The HyperGUI manages it by avoiding screen refreshes as much as possible. In a game or other dynamic multimedia program, the screen (or part of it) is redrawn and refreshed tens of times a second, so there is no need for GUI to ask more refreshes in response of input events; and in a static application each event may change a tiny part of the screen, and only that part needs redrawing. HyperGUI has the flexibility to work in both states.
