OpenGUI is a high-Level C/C++ graphics & windowing library built upon a fast, low-level x86 asm graphics kernel. It is under LGPL license. OpenGUI provides 2D drawing primitives and an event-driven windowing AP for easy application development, and it supports the BMP image file format. It's very powerful, but very easy to use. You can write apps in the old Borland BGI style or in a windowed style like QT. OpenGUI supports the keyboard and mouse as event sources, and the Linux framebuffer/svgalib as drawing backends. Mesa3D is also supported under Linux. On now 8, 15, 16 and 32-bit color modes are available.

OpenGUI is a very fast multi-platform 32-bit graphics library/GUI for MS-DOS (DPMI client/DJGPP), QNX (Watcom or GCC) and Linux. It can be used to create graphic applications and games for these Operating Systems. The library can be used with GNU] C++ (from ver. 2.7.2) or Watcom C++ (from 9.5) and NASM assembler (0.97). The library is very stable and is ready for programs that require realtime drawing and Windows GUI.

Features:

  • LGPL
  • ultra-fast (asm kernel & MMX support)
  • the most robust library for the Linux FrameBuffer
  • support for resolutions ranging from 320x200 to 1600x1200 and 8, 15, 16 and 32 color depths windowing system
  • object-oriented multi-platform API (DJGPP, WATCOM, GCC, Linux, QNX)
  • full application development framework (configuration file, file & color dialogs, etc.)
  • professionally tested & actively used for some yearsa tool for interactive code generation (draw & run)and much more

The library consists of three layers.

  • The first layer is a hand-coded and fast assembler kernel. This layer does the biggest piece of hard work.
  • The second layer implements the API for drawing graphics primitives like lines, rectangles, circles etc. This layer is comparable to Borland BGI API.
  • The third layer is written with C++ and offers a complete object set for the GUI developer. The third layer implements objects like input windows, buttons, menus, bitmaps etc, with addition of integrated mouse & keyboards support.
