- All Implemented Interfaces:
- javax.accessibility.Accessible, javax.swing.event.CaretListener, javax.swing.event.DocumentListener, java.util.EventListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.beans.PropertyChangeListener, java.io.Serializable, javax.swing.event.TreeSelectionListener
- public class ElementTreePanel
- extends javax.swing.JPanel
- implements javax.swing.event.CaretListener, javax.swing.event.DocumentListener, java.beans.PropertyChangeListener, javax.swing.event.TreeSelectionListener
Displays a tree showing all the elements in a text Document. Selecting
a node will result in reseting the selection of the JTextComponent.
This also becomes a CaretListener to know when the selection has changed
in the text to update the selected item in the tree.

tree
protected javax.swing.JTree tree
- Tree showing the documents element structure.
editor
protected javax.swing.text.JTextComponent editor
- Text component showing elemenst for.
treeModel
protected ElementTreePanel.ElementTreeModel treeModel
- Model for the tree.
updatingSelection
protected boolean updatingSelection
- Set to true when updatin the selection.
ElementTreePanel
public ElementTreePanel(javax.swing.text.JTextComponent editor)
setEditor
public void setEditor(javax.swing.text.JTextComponent editor)
- Resets the JTextComponent to
editor. This will update
the tree accordingly.
propertyChange
public void propertyChange(java.beans.PropertyChangeEvent e)
- Invoked when a property changes. We are only interested in when the
Document changes to reset the DocumentListener.
- Specified by:
propertyChange in interface java.beans.PropertyChangeListener
insertUpdate
public void insertUpdate(javax.swing.event.DocumentEvent e)
- Gives notification that there was an insert into the document. The
given range bounds the freshly inserted region.
- Specified by:
insertUpdate in interface javax.swing.event.DocumentListener
removeUpdate
public void removeUpdate(javax.swing.event.DocumentEvent e)
- Gives notification that a portion of the document has been
removed. The range is given in terms of what the view last
saw (that is, before updating sticky positions).
- Specified by:
removeUpdate in interface javax.swing.event.DocumentListener
changedUpdate
public void changedUpdate(javax.swing.event.DocumentEvent e)
- Gives notification that an attribute or set of attributes changed.
- Specified by:
changedUpdate in interface javax.swing.event.DocumentListener
caretUpdate
public void caretUpdate(javax.swing.event.CaretEvent e)
- Messaged when the selection in the editor has changed. Will update
the selection in the tree.
- Specified by:
caretUpdate in interface javax.swing.event.CaretListener
valueChanged
public void valueChanged(javax.swing.event.TreeSelectionEvent e)
- Called whenever the value of the selection changes.
- Specified by:
valueChanged in interface javax.swing.event.TreeSelectionListener
getTree
protected javax.swing.JTree getTree()
getEditor
protected javax.swing.text.JTextComponent getEditor()
getTreeModel
public javax.swing.tree.DefaultTreeModel getTreeModel()
updateTree
protected void updateTree(javax.swing.event.DocumentEvent event)
- Updates the tree based on the event type. This will invoke either
updateTree with the root element, or handleChange.
updateTree
protected void updateTree(javax.swing.event.DocumentEvent event,
javax.swing.text.Element element)
- Creates TreeModelEvents based on the DocumentEvent and messages
the treemodel. This recursively invokes this method with children
elements.
getPathForIndex
protected javax.swing.tree.TreePath getPathForIndex(int position,
java.lang.Object root,
javax.swing.text.Element rootElement)
- Returns a TreePath to the element at
position.
