Constructor Detail

FeatureTreeModel

public FeatureTreeModel(ProjectContainer container)

Method Detail

getContainer

public ProjectContainer getContainer()

setContainer

public void setContainer(ProjectContainer pContainer)

getRootFeature

public Feature getRootFeature()

getRoot

public java.lang.Object getRoot()

Returns the root of the tree. Returns null only if the tree has no nodes.

Specified by:

getRoot in interface javax.swing.tree.TreeModel

Returns:

the root of the tree

getChild

public java.lang.Object getChild(java.lang.Object parent,
                                 int index)

Returns the child of parent at index index in the parent's child array. parent must be a node previously obtained from this data source. This should not return null if index is a valid index for parent (that is index >= 0 && index < getChildCount(parent)).

Specified by:

getChild in interface javax.swing.tree.TreeModel

Parameters:

parent - a node in the tree, obtained from this data source

Returns:

the child of parent at index index

getChildCount

public int getChildCount(java.lang.Object parent)

Returns the number of children of parent. Returns 0 if the node is a leaf or if it has no children. parent must be a node previously obtained from this data source.

Specified by:

getChildCount in interface javax.swing.tree.TreeModel

Parameters:

parent - a node in the tree, obtained from this data source

Returns:

the number of children of the node parent

isLeaf

public boolean isLeaf(java.lang.Object node)

Returns true if node is a leaf. It is possible for this method to return false even if node has no children. A directory in a filesystem, for example, may contain no files; the node representing the directory is not a leaf, but it also has no children.

Specified by:

isLeaf in interface javax.swing.tree.TreeModel

Parameters:

node - a node in the tree, obtained from this data source

Returns:

true if node is a leaf

valueForPathChanged

public void valueForPathChanged(javax.swing.tree.TreePath path,
                                java.lang.Object newValue)

Messaged when the user has altered the value for the item identified by path to newValue. If newValue signifies a truly new value the model should post a treeNodesChanged event.

Specified by:

valueForPathChanged in interface javax.swing.tree.TreeModel

Parameters:

path - path to the node that the user has altered.

newValue - the new value from the TreeCellEditor.

getIndexOfChild

public int getIndexOfChild(java.lang.Object parent,
                           java.lang.Object child)

Returns the index of child in parent.

Specified by:

getIndexOfChild in interface javax.swing.tree.TreeModel

addTreeModelListener

public void addTreeModelListener(javax.swing.event.TreeModelListener pListener)

Adds a new tree model listener

Specified by:

addTreeModelListener in interface javax.swing.tree.TreeModel

Parameters:

pListener - Listener to add

removeTreeModelListener

public void removeTreeModelListener(javax.swing.event.TreeModelListener pListener)

Removes a listener

Specified by:

removeTreeModelListener in interface javax.swing.tree.TreeModel

Parameters:

pListener - Listener to remove

removeAllTreeModelListener

public void removeAllTreeModelListener()

Removes all tree listeners

fireTreeStructureChanged

protected void fireTreeStructureChanged(Feature pFeature)

Notifies all listeners

modelChanged

public void modelChanged(ModelEvent ev)

Description copied from interface: ModelListener

Invoked on model changes.

Specified by:

modelChanged in interface ModelListener

Parameters:

ev - Model event
