Class JMCScrollPane

  java.awt.Component
      java.awt.Container
          java.awt.Panel
              org.strbio.util.JMCScrollPane

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class JMCScrollPane
extends java.awt.Panel

This is basically a lame re-implementation of ScrollPane, but it works with AWT 1.0 applets... can therefore use for Netscape 4.0, which supports Java 1.1 with AWT 1.0. Scroll bars are always visible, even when unnecessary.

  Version 1.01, 8/14/98 - made it really AWT 1.0 compliant; i.e. no
    Adjustable, size(), etc..
  Version 1.0, 8/12/98 - original version.
  

Version:
