Method Detail

initialize

public void initialize(AWTEvent ev,
                       com.klg.jclass.cell.JCCellInfo info,
                       Object o)

Description copied from interface: JCCellEditor

The container calls initialize() before the edit starts to let the editor know what kind of event started the edit (via the AWTEvent object).
Note: The size of the cell comes from info.getDrawingArea().

Implementors must handle null AWTEvents.

Specified by:

initialize in interface JCCellEditor

Parameters:

ev - event that initiated the edit operation

info - cell that displays information for the editor

o - item to be edited

getComponent

public Component getComponent()

Returns the edit component.

Specified by:

getComponent in interface JCCellEditor

Returns:

actual component that will be used to do the editing

getCellEditorValue

public Object getCellEditorValue()

Returns the object to be commited.

Specified by:

getCellEditorValue in interface JCCellEditor

Returns:

value contained in the editor

isModified

public boolean isModified()

Returns true if the data has been modified.

Specified by:

isModified in interface JCCellEditor

Returns:

fireValidated

protected boolean fireValidated(com.klg.jclass.cell.validate.JCValidateEvent ev)

stopCellEditing

public boolean stopCellEditing()

Called when the edit process is stopped

Specified by:

stopCellEditing in interface JCCellEditor

Returns:

true if editing was stopped

cancelCellEditing

public void cancelCellEditing()

Called when the edit process is cancelled.

Specified by:

cancelCellEditing in interface JCCellEditor

getPreferredSize

public Dimension getPreferredSize(Graphics gc,
                                  com.klg.jclass.cell.JCCellInfo cellInfo,
                                  Object o)

getReservedKeys

public com.klg.jclass.cell.JCKeyModifier[] getReservedKeys()

No keys are reserved.

Specified by:

getReservedKeys in interface JCCellEditor

Returns:

keys that the editor would like to reserve for itself

addCellEditorListener

public void addCellEditorListener(com.klg.jclass.cell.JCCellEditorListener l)

Add a listener to the list that's notified when the editor starts, stops, or cancels editing.

Specified by:

Parameters:

l - the CellEditorListener

removeCellEditorListener

public void removeCellEditorListener(com.klg.jclass.cell.JCCellEditorListener l)

Remove a listener from the list that's notified

Specified by:
