public interface CellEditor
Having this interface enables complex components (the client of the
editor) such as
JTable to allow any generic editor to
edit values in a table cell, or tree cell, etc. Without this generic
JTable would have to know about specific editors,
etc. In addition, without this interface, clients of editors such as
JTable would not be able
to work with any editors developed in the future by the user
or a 3rd party ISV.
To use this interface, a developer creating a new editor can have the
new component implement the interface. Or the developer can
choose a wrapper based approach and provide a companion object which
CellEditor interface (See
JCellEditor for example). The wrapper approach
is particularly useful if the user want to use a 3rd party ISV
JTable, but the ISV didn't implement the
CellEditor interface. The user can simply create an object
that contains an instance of the 3rd party editor object and "translate"
CellEditor API into the 3rd party editor's API.
|Modifier and Type||Method and Description|
Adds a listener to the list that's notified when the editor stops, or cancels editing.
Tells the editor to cancel editing and not accept any partially edited value.
Returns the value contained in the editor.
Asks the editor if it can start editing using
Removes a listener from the list that's notified
Returns true if the editing cell should be selected, false otherwise.
Tells the editor to stop editing and accept any partially edited value as the value of the editor.
boolean isCellEditable(EventObject anEvent)
anEventis in the invoking component coordinate system. The editor can not assume the Component returned by
getCellEditorComponentis installed. This method is intended for the use of client to avoid the cost of setting up and installing the editor component if editing is not possible. If editing can be started this method returns true.
anEvent- the event the editor should use to consider whether to begin editing or not
boolean shouldSelectCell(EventObject anEvent)
anEvent- the event the editor should use to start editing
void addCellEditorListener(CellEditorListener l)
l- the CellEditorListener
void removeCellEditorListener(CellEditorListener l)
l- the CellEditorListener
