Interface IEditErrorHandler

All Known Implementing Classes:

AbstractEditErrorHandler, DialogErrorHandling, DiscardValueErrorHandling, LoggingErrorHandling, RenderErrorHandling

public interface IEditErrorHandler

An IEditErrorHandler will be used if on data conversion or validation while editing via ICellEditor an error occurs. Such a handler is usually registered in the IConfigRegistry, using the EditConfigAttributes.

For some ICellEditors they are also used for just in time conversion/validation to render the wrong input immediately for feedback to the user. This is done e.g. in the TextCellEditor.
