Description: This tutorial is the first in a series of "would-be" tutorials about graphical programming in the X window environment. By itself, it is useless. A real X programmer usually uses a much higher level of abstraction, such as using Motif (or its free version, lesstiff), GTK, QT and similar libraries. However, we need to start somewhere. More than this, knowing how things work down below is never a bad idea.After reading this tutorial, one would be able to write very simple graphical programs, but not programs with a descent user interface. For such programs, one of the previously mentioned libraries would be used.
