Class FontUtils

java.lang.Object
  com.jidesoft.swing.FontUtils

public class FontUtils
extends Object

This is a global class to keep a record of Font so that we can improve the performance and memory usage in various scenarios like StyledLabel.

In this class, we have a global map of font and derived font. It probably could be huge after running a long time. In that case, you need explicitly clear the font cache in this class by using clearDerivedFontCache() .
