EOColumnEditor
- Inherits from:
- Object
- Implements:
- javax.swing.table.TableCellEditor
- Package:
- com.webobjects.eointerface.swing
Class Description
EOColumnEditor is an abstract class that implements generalized cell editing management for javax.swing.JTables. Swing specifies that JTable cell editing is performed by an object implementing the javax.swing.table.TableCellEditor interface. EOColumnEditor implements this interface in a generalized way, and concrete subclasses such as EOTextColumnEditor perform component-specific instantiation and event communication.
The most important function of an EOColumnEditor instance is mediating between its Component and the EOTableColumnAssociation that's bound to the edited column. This mediation enables the validation of edited values that associations are required to perform.
Create a subclass of EOColumnEditor if you want to use a Component for JTable editing for which no EOColumnEditor is implemented.
