XTC - The X Tool Collection

Date and Time

MIT Building 3-133

A low-level X11 protocol library written in native Java


Eugene O'Neil will be demonstrating the X Tool Collection (XTC), an X Window client library written in pure Java. XTC bypasses the need for native C libraries such as xlib by directly implementing the low-level X Window protocol, taking full advantage of Java's object-oriented, multi-threaded environment. XTC is remarkably efficient for a “pure” Java library, since it relies on the X Window server to do most of the real work.

The following topics will be discussed:

  • the origin and goals of XTC
  • protocol requests and replies
  • event handling
  • polygons and bezier curves
  • fonts and text
  • images and pixmaps
