  • Method Details

    • stopCellEditing

      public boolean stopCellEditing()
      Specified by:
      stopCellEditing in interface CellEditor
      Overrides:
      stopCellEditing in class DefaultCellEditor

    • 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.

    • getTableCellEditorComponent

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

      Overrides:
      getTableCellEditorComponent in class DefaultCellEditor

    • getCellEditorValue

      public Number getCellEditorValue() throws IllegalStateException

      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
      Throws:
      IllegalStateException - if current value invalid

    • getComponent

    • createFormattedTextFieldX

      private static JFormattedTextField createFormattedTextFieldX(NumberFormat format)
      Creates and returns a JFormattedTextField configured with SwingX extended NumberFormat and StrictNumberFormatter. This method is called if the constructor parameter useStrictFormatter is true. Use a static method so that we can do some stuff before calling the superclass.

    • createFormattedTextField

      private static JFormattedTextField createFormattedTextField(NumberFormat formatter)
      Creates and returns a JFormattedTextField configured with defaults. This method is called if the contructor useStrictFormatter is false.

      Use a static method so that we can do some stuff before calling the superclass.
