- public static class CSH.DisplayHelpFromFocus
- extends java.lang.Object

An ActionListener that displays the help of the
object that currently has focus. This method is used
to enable HelpKey action listening for components other than
the RootPane. This listener determines if the
object with the current focus has a helpID. If it does, the helpID
is displayed,
otherwise the helpID on the action's source is displayed (if one exists).
