public class JUComboBoxCtrlBinding
extends JUCtrlListBinding
implements java.awt.event.ActionListener, javax.swing.MutableComboBoxModel

Implements binding a Swing JComboBox or JUComboBox to a BC4J Attribute or ViewObject or as an LOV (list of values).

A combobox can be bound in the following ways:

• Display single or multiple attributes for rows in a RowSet and iterate the rowset currency.
• Display single attribute from rows in a RowSet and update another attribute in a different ViewObject.
• Display single or multiple attributes from rows in a RowSet and update one or multiple attributes in a different ViewObject (similar to an LOV).
• Display a static LOV and update one attribute in a BC4J row.

This class also implements ActionListener interface and listens to ActionEvents from the bound combobox. On an action event, it either performs an update of the target ViewObject attributes, or iterates a target ViewObject as per the list operation mode set in the constructor.

JUComboBoxCtrlBinding

public JUComboBoxCtrlBinding(java.lang.Object cb,
                             JUIteratorBinding iterBinding,
                             java.lang.String[] attrNames,
                             int listOperMode)

Binds a ComboBox to a RowSet associated with the given iterator binding and based on listOperMode setting, either iterates the currency on the target iterator or updates the attribute value for the given attribute (in attrNames) in the current row in the target RowSet. Note that the combobox will display and (optionally)update the same attribute from a RowSet.

Parameters:

cb - JComboBox or JUComboBox with which to associate this binding.

iterBinding - Provides the RowSet from which this binding accesses data to display in the combobox and optionally the current row for which attribute(s) are to be updated.

attrNames - An ordered array of attribute names to display and optionally update in a ViewObject.

listOperMode - Can be one of two values:

• LIST_OPER_SET_ATTRIBUTE (the default) to indicate that this combobox is to be used to update attributes in the current row of the associated RowSet.
• LIST_OPER_NAVIGATE to indicate that this combobox should be used to iterate currency in the associated RowSet.

JUComboBoxCtrlBinding

public JUComboBoxCtrlBinding(java.lang.Object cb,
                             JUIteratorBinding iterBinding,
                             java.lang.String[] attrNames,
                             java.lang.Object[] valueList)

Binds a combobox to an attribute in the associated RowSet. The values displayed in combobox are provided by the valueList objects.

Parameters:

cb - JComboBox or JUComboBox with which to associate this binding.

iterBinding - Provides the RowSet that is used to update current selection from the combobox into the current row in the rowset.

attrNames - Provides the name of an attribute (only one attribute is updateable in this mode).

valueList - A static list of values displayed as options in the combobox from which to select.

JUComboBoxCtrlBinding

public JUComboBoxCtrlBinding(java.lang.Object cb,
                             JUIteratorBinding iterBinding,
                             java.lang.String[] attrNames,
                             JUIteratorBinding listIterBinding,
                             java.lang.String[] listAttrNames,
                             java.lang.String[] listDisplayAttrNames)

Binds separate ViewObject/RowSets for display and update to the same ComboBox. Use this binding constructor to provide a separate iterator binding for update and a separate iterator binding which provides rows for display in the combobox. Optionally, the attributes displayed can be different from the attributes that should be used to update a corresponding set of attributes in the target/updateable ViewObject.

Parameters:

cb - JComboBox or JUComboBox to associate this binding with.

iterBinding - Provides the RowSet in which the current row is updated based on selection in the combobox.

attrNames - An ordered array of attribute names to update in a ViewObject. This list should have the same number of attributes as in listAttrNames, which provides the corresponding attribute names from the display ViewObject/RowSet.

listIterBinding - Provides the RowSet which is used to display data in the combobox.

listAttrNames - An ordered list of attribute names, which are used to get the values to update into the attributes from the attrNames list in the target ViewObject. If this list is null, then the attribute names for display are set the same as attrNames.

listDisplayAttrNames - An ordered list of attribute names that specify the attributes to display from rows in the display ViewObject/RowSet. If this list is null, then attribute names are assumed to be same as in attrNames.

Method Detail

init

protected void init(javax.swing.JComboBox cb)

getModelImpl

protected javax.swing.MutableComboBoxModel getModelImpl(javax.swing.JComboBox control)

Sets the model reference in this binding class by using the current model in the combobox. Returns the same model reference. If there is no model in the combobox, creates a DefaultComboBoxModel and returns that.

Overrides:

setupListItems in class JUCtrlListBinding

Parameters:

clean - Controls whether to clean the existing entries in the combobox.

keepSelectedIndex - Controls whether to maintain current index as the selected index after the display data is updated. If this value is true, the current index is maintained. However if the current index is more than the number of items in the combobox, then the selection is reset to the first item.

refreshComboList

protected void refreshComboList(boolean clean,
                                boolean keepSelectedIndex,
                                boolean usePreferredList)

getComboDisplayAttrs

protected AttributeDef[] getComboDisplayAttrs()

isRefreshingList

public boolean isRefreshingList()

updateValueToCurrentRow

protected int updateValueToCurrentRow(javax.swing.JComboBox combo,
                                      int comboSize,
                                      int index,
                                      boolean usePreferredList)

getValueAt

public java.lang.Object getValueAt(int attrIndex)

Returns the currently selected item from the list model. This is used by the framework to update the values into the target rowset.

Overrides:

getValueAt in class JUCtrlListBinding

Parameters:

attrIndex - This argument is ignored by this method.

setValueAt

public void setValueAt(java.lang.Object value,
                       int attrIndex)

Finds the item in the combobox that matches the given value and sets it as the current item.

Overrides:

setValueAt in class JUCtrlListBinding

Parameters:

value - This value is used in findMatchingListValue method to find out the item in the combobox that represents the given value. If the value is not found, then no item is selected in the list.

attrIndex - This argument is ignored by this method.

setDataValueAt

public void setDataValueAt(java.lang.Object value,
                           int attrIndex)

Should be used by applications to update both the combobox selection and the correpsonding attributes in the current row of the target viewobject.

Overrides:

setDataValueAt in class JUCtrlListBinding

Parameters:

value - This value is used in findMatchingListValue method to find out the item in the combobox that represents the given value. If the value is not found, then no item is selected in the list.

attrIndex - This argument is ignored by this method.

setSelectedIndex

public void setSelectedIndex(int listIndex)

Sets the item at the given index as current selection in the listbox.

Overrides:

setSelectedIndex in class JUCtrlListBinding

isControlQueriable

protected boolean isControlQueriable()

Returns true, so that JTextComponents can participate in a query in the Find Mode of the containing panel. When the containing panel Binding object is set to Find mode, it queries all control-bindings in it and disables those controls whose bindings return false for this method during the Find mode. The return value from this method indicates whether to consult an attribute definition for queriability.

An application could create a subclass of this binding object and return false from this method to prevent the associated control from participating in find mode. Additionally, a BC4J attribute itself can control whether that attribute can participate in Query or not. That property takes precedence over this method's return, if this method returns true. In other words, if this binding is bound to a CLOB attribute type and the attribute definition for that attribute indicates that it is not queriable, then the default behavior of JUPanelBinding in Find mode will be to disable this binding's control, even though this method returns true.

Overrides:

isControlQueriable in class JUCtrlListBinding

actionPerformed

Use this binding when two ViewObjects are to be used in this combobox: one for displaying the list of values and the other ViewObject the rows of which are updated. Optionally, a UI can provide a cell renderer for the list and a editor which can be used to implement ComboBox customization. By default, if this binding method creates an instance of JUMultiAttrListCellRenderer and JUMultiAttrListCellEditor to display and edit LOVs.
