public class JFormattedComboBox
extends JComboBox
implements JFormattedComponent, ActionListener

JFormattedComboBox extends javax.swing.JComboBox and implements com.ibm.etools.iseries.ui.JFormattedComponent. It is a combo box that allows you to define a field model, which can then specify a formatter, a validator, a keystroke verifier, and data attributes. By default, JFormattedComboBox uses AS400FieldModel which by default uses EditcodeEditwordFormatter, ComparisonRangeValidator, NumericCharacterDocument, and the default data type is character, data length is 10, and decimal places is 0.

A formatter defines how a string can be formatted. If the combo box is set to editable, the editor used is a JFormattedTextField. Any data that the user types in will be validated by the validator and will be formatted automatically in the format defined in the formatter when the user has finished typing in the field; that is, when the focus is lost from the comboBox. Data input into an editable field and any string that is added to the combo box pull down list will be validated and formatted automatically. There is an EditcodeEditwordFormatter class that the AS/400 user can use. It allows you to select an editcode or set a user-defined editword. If none of the editcodes or editwords meet the user requirements, users can create their own formatter class and set the JFormattedComboBox's field model to use the user-defined formatter.

A validator is a class that can validate field values. Text that is entered in an editable field or items added to the combo box list can be passed to a validator for validation prior passing it to formatting and setting the text. Apart from the validator that validates the data, the JFormattedComboBox itself also validates the data type, data length, and decimal places of an editable field or an item added to the list. There is a ComparisonRangeValidator class which performs a comparison validation or range validation. A comparison validation compares a field value in relation to another value. A range validation validates against a range of values. Again, if ComparisonRangeValidator does not meet the user requirements, users can write their own validator class and set the JFormattedComboBox's field model to use the newly defined validator.

A keystroke verifier is a document class that is used to verify keystroke entry. A document is a data model in an Model-View-Controller (MVC) relationship that controls the data input. Characters that are not defined in the data model are not allowed to be entered; there will be a beep to notify the user at a keystroke level. There are two predefined keystroke verifier classes: NumericCharacterDocument and UpperCaseDocument. If none of these keystroke verifier document classes meet the user requirements, users can write their own document class and set the JFormattedComboBox's field model to use the user-defined class.

DataAttributes is a class that is used to hold the field attributes such as auto advance flag, data type, data length, decimal point symbol, size of decimal places and background color when invalid entry occurs. By default, autoAdvance is set to false, which means that if a JFormattedComboBox component is editable, the control will not automatically advance to the next component when the maximum data length of the field is reached. Additionally, the data type is set to character; the data length is 10; the decimal point symbol will automatically pick up the locale value of a decimal point; the decimal places are set to 0; and the reverseImageColor is set to java.awt.Color.red. These are "bound" properties, so you can change these values as you wish. Please note that the Attributes field must be an instance of com.ibm.etools.iseries.ui.DataAttributes; otherwise java.beans.PropertyVetoException will be thrown at run time.

JFormattedComboBox does not support the editmask feature.

Experienced users can also define or change the FormattedComboBoxEditor. FormattedComboBoxEditor is a ComboBoxEditor, which defines the editor of the editable field. The default editor is MetalFormattedComboBoxEditor which uses JFormattedTextField as the editor. The predefined FormattedComboBoxEditor classes are BasicFormattedComboBoxEditor and MetalFormattedComboBoxEditor.

Experienced users can also define their own ListCellRenderer. The default ListCellRenderer is FormattedTextRenderer which uses JFormattedLabel as cells in the pull down list of the combo box.

The following is a sample:

 public class JFormattedComboBoxSample extends javax.swing.JFrame

                                                                "0(   )   -    ");
 
        String data[] = {"4161112222", "1234567890", "9057778888", "4165556666"};
        JFormattedComboBox cb = new JFormattedComboBox(data,new AS400FieldModel(att, formatter));
 
        
        cb.setPreferredSize(new Dimension(150,25));
        cb.setSelectedIndex(0);
        pr.add(cb);

Note: This documentation is for part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
