GTK's function names are very descriptive. Once youhave an understanding of how things work, it's not difficult to figureout how to use a widget simply by looking at its functiondeclarations. This, along with a few examples from others' code, andit should be no problem.</P><P>When you do come to understand all the functions of a new undocumentedwidget, please consider writing a tutorial on it so others may benefitfrom your time.</P><DIVCLASS="SECT1"><H1CLASS="SECT1"><ANAME="SEC-CURVES">16.1.
