Article contents:== Outdated egg! This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for [[/eggref/5/xlib-utils|the CHICKEN 5 version of this egg]], if it exists. If it does not exist, there may be equivalent functionality provided by another egg; have a look at the [[https://wiki.call-cc.org/chicken-projects/egg-index-5.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. == xlib-utils [[toc:]] == Description Grab-bag of utilities for use with the xlib egg. This includes a set of procedures for working with X properties, events, and EWMH desktops, as well as a datatype called xcontext, which is a way to package up a display, a screen, a xinerama-screen, and a window into a single convenient record.
