public interface DialogListener
PlugIns or PlugInFilters that want to listen to changes in a GenericDialog
without adding listeners for each dialog field should implementthis method.
The dialogItemChanged method of a PlugIn or PlugInFilter can and should read
the various dialog items by the appropriate GenericDialog methods like
getNextNumber (items that are not read in the dialogItemChanged method will
not be recorded by the Macro recorder).
The PlugIn or PlugInFilter has to be added to the GenericDialog by
its addDialogListener method:
gd.addDialogListener(this);
