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);
