ucar.unidata.ui
Class Help

java.lang.Object
  ucar.unidata.ui.Help

public class Help
extends Object

Convenience routines for accessing JavaHelp. These are static routines, so that they can be accessed from deeeply nested methods without having to pass the HekpSet object all over the place. The assumption is that there is only one helpset per application. The application should call setTopDir() to set the root directory, before any other calls are made into the help system. The helpset is then found at:

 //HelpSet.hs 

Inside the application, Help is accessed by ucar.unidata.ui.Help.getDefaultHelp().gotoTarget("top"); The actual target names must be valid names in the Map.xml file. I use "top" as the convention for the general Help page.
