Description (last modified by jermar)

The HelenOS native GUI environment should be further improved and extended.

Details
HelenOS features a compositing GUI described in Petr Koupy's master thesis (see below). The GUI is fairly basic and offers vast room for improvements. The goal of this project is to implement a reasonable subset of the following.
  • support for direct rendering in graphic driver infrastructure
  • more drawing operations in drawing library (lines, curves, polygons, circles, etc.)
  • retained scene description in drawing library
  • hardware acceleration of drawing library
  • better quality of drawing library output (advanced filtering, antialiasing)
  • better precision of drawing library output (floating point coordinates and pixels)
  • support for more image and font formats in drawing library
  • more widgets in widget toolkit (menu bars, scrolls bars, edit boxes, list boxes, etc.)
  • support to minimize and maximize windows
  • desktop environment (task bar, icons)
  • improvements of terminal emulator (resizing, scrolling, history)
  • console applications awareness of resizing and termination of their terminal emulator
What Gains and Benefits will this bring?
HelenOS will become more usable and more user-friendly and visually appealing.

Required skills
A successful applicant will have good skills of programming in the C language and the ability to survive in a non-standard non-POSIX environment. Previous experience with a graphics stack implementation would be beneficial.
