Instantiates an editor with default NumberFormat and NumberFormatter depending on useStrictFormatter.

Parameters:

useStrictFormatter - if true, uses a StrictNumberFormatter, else uses default NumberFormatter

Method Detail

stopCellEditing

public boolean stopCellEditing()

Description copied from class: javax.swing.DefaultCellEditor

Forwards the message from the CellEditor to the delegate.

Specified by:

stopCellEditing in interface CellEditor

Overrides:

stopCellEditing in class DefaultCellEditor

Returns:

true

See Also:

DefaultCellEditor.EditorDelegate.stopCellEditing()

isValid

protected boolean isValid()

Returns a boolean indicating whether the current text is valid for instantiating the expected Number type.

Returns:

true if text is valid, false otherwise.

getNumber

protected Number getNumber()
                    throws Exception

Returns the editor value as number. May fail for a variety of reasons, as it forces parsing of the current text as well as reflective construction of the target type.

Returns:

the editor value or null

Throws:

Exception - if creation of the expected type fails in some way.

hasStrictFormatter

protected boolean hasStrictFormatter()

Returns:

getTableCellEditorComponent

public Component getTableCellEditorComponent(JTable table,
                                             Object value,
                                             boolean isSelected,
                                             int row,
                                             int column)

Override and set the border back to normal in case there was an error previously

Specified by:

getTableCellEditorComponent in interface TableCellEditor

Overrides:

getTableCellEditorComponent in class DefaultCellEditor

Parameters:

table - the JTable that is asking the editor to edit; can be null

value - the value of the cell to be edited; it is up to the specific editor to interpret and draw the value. For example, if value is the string "true", it could be rendered as a string or it could be rendered as a check box that is checked. null is a valid value

isSelected - true if the cell is to be rendered with highlighting

row - the row of the cell being edited

column - the column of the cell being edited

Returns:

the component for editing

getCellEditorValue

public Number getCellEditorValue()
                          throws IllegalStateException

Forwards the message from the CellEditor to the delegate.

Overridden to instantiate a Number of the expected type. Note that this may throw a IllegalStateException if invoked without querying for a valid value with stopCellEditing. This should not happen during normal usage.

Specified by:

getCellEditorValue in interface CellEditor

Overrides:

getCellEditorValue in class DefaultCellEditor

Returns:

the value contained in the editor

Throws:

IllegalStateException - if current value invalid

See Also:

DefaultCellEditor.EditorDelegate.getCellEditorValue()

getComponent

public JFormattedTextField getComponent()

Returns a reference to the editor component.

Convenience override with type cast.

Overrides:

getComponent in class DefaultCellEditor

Returns:

the editor Component
