Methods Summary
public java.lang.StringgetAppletInfo()

 
    return "Click2 by Hans Mueller.  This version of the Click applet fixes Click1 by extending the nested TargetListener class with methods that redispatch the mouse motion events from the target columns to the applet.  Note that we're translating the events coordinates from the source components coordinate system to the applets coordinate system. This applet requires JDK 1.1.";
