All Implemented Interfaces:

XMLChangeListener, java.awt.event.ActionListener, java.awt.image.ImageObserver, java.awt.ItemSelectable, java.awt.MenuContainer, java.io.Serializable, java.util.Comparator, java.util.EventListener, javax.accessibility.Accessible, javax.swing.event.ListDataListener

public class AttributeSelectionComboBox
extends javax.swing.JComboBox
implements XMLChangeListener, java.awt.event.ActionListener, java.util.Comparator

This class is a extends a dropdown list. It populates the list with attribute of a speccified tag.

It also allows a user to select an item from the drop down list, and the component will modify the XML as appropriate.

This is also an XMLChangeListener, so that the contents of the drop down list will refresh accordingly.

                                  java.lang.String extraTag2)

Creates a new instance of AttributeSelectionComboBox. The Constructor will populate the list, and set the required listeners.

Parameters:

that - the XML Editor to use.

policyTag - the Main 'root' subpolicy tag to read the attributes from.

tag - the tag below the subpolicy 'root' element to read attributes.

attributeID - the attribute name to read.

index - an integer location of the tag.

newPolicy - the new 'root' sub-policy tag to write to.

newTag - the tag below the subpolicy 'root' element to write to.

newSubTag - an extra tag offering a 3rd level for tags.

extraTag - extra tag require to implement the TargetAccessPolicy.

extraTag2 - extra tag require to implement the TargetAccessPolicy.

Method Detail

getListData

public void getListData()

Method that fills the JComboBox with the required Values. First will find the policy block. Get its ChildElements.

For all child elements that have a tag equal to the one of interest to us, store the required attribute in an array.
Sorts the Array and, Fills the ComboBox.

getSelectedXMLItem

public void getSelectedXMLItem()

This method is used so that when the component is refreshed, the component will display the correct item that is saved in the Document.

compare

public int compare(java.lang.Object o1,
                   java.lang.Object o2)

Interface method, to compare strings ignoring the case..

Specified by:

compare in interface java.util.Comparator

XMLChanged

public void XMLChanged(XMLChangeEvent ev)

XMLChanged Method. Basically unsets the actionlistener otherwise when filling the new data will fire actionPerformed Events. Sets the new data in the list. Sets the actionListener back on.

Specified by:

XMLChanged in interface XMLChangeListener

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

What to do when something is Selected in the dropdown list.

It will take care of modifying the XML in the context that it is placed in itslef.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

Overrides:

actionPerformed in class javax.swing.JComboBox

getRootNode

public org.w3c.dom.Node getRootNode()

Method that checks that returns the current policy root node.

Returns:

the current policy root node. If the Document is null, the returned root node will be null.
