public class TextComponentOutputStream

extends java.io.OutputStream

Creation : 4 sept 2001 OutputStream which writes into standard awt TextComponent. The output method (append() vs setText()) is choosen depending of the given component. A maximal component's text capacity can be defined. When reached its capacity, the component will erase the beginning of its content.

Since:

0.1
