Constructor Detail

DefaultTreeModelWrapper

public DefaultTreeModelWrapper()

Creates an empty DefaultTreeModelWrapper.

DefaultTreeModelWrapper

public DefaultTreeModelWrapper(TreeModel model)

Creates a DefaultTreeModelWrapper from for a tree model.

Parameters:

model - the original tree model

Method Detail

setActualModel

public void setActualModel(TreeModel model)

Sets the actual tree model.

Specified by:

setActualModel in interface TreeModelWrapper

Parameters:

model - the original tree model

getActualModel

public TreeModel getActualModel()

Gets the actual tree model. Since TreeModelWrapper is just a wrapper around another tree model, this method will return you the actual tree model.

Specified by:

getActualModel in interface TreeModelWrapper

Returns:

the actual tree model.

getRoot

public Object getRoot()

Implementations of the method in TreeModel. it delegates to the actual tree model.

Specified by:

getRoot in interface TreeModel

Returns:

the root

getIndexOfChild

public int getIndexOfChild(Object parent,
                  Object child)

Implementations of the method in TreeModel. it delegates to the actual tree model after index conversion.

Specified by:

getIndexOfChild in interface TreeModel

getChild

public Object getChild(Object parent,
              int index)

Implementations of the method in TreeModel. it delegates to the actual tree model after index conversion.

Specified by:

getChild in interface TreeModel

getChildCount

public int getChildCount(Object parent)

Implementations of the method in TreeModel. it delegates to the actual tree model after index conversion.

Specified by:

getChildCount in interface TreeModel

isLeaf

public boolean isLeaf(Object node)

Implementations of the method in TreeModel. it delegates to the actual tree model.

Specified by:

isLeaf in interface TreeModel

getListModelWrapper

protected ListModelWrapper getListModelWrapper(Object node)

Get the list model wrapper for the node.

Parameters:

node - the tree node

Returns:

the list model wrapper associated with the node.

See Also:

setListModelWrapper(Object, com.jidesoft.list.ListModelWrapper)

setListModelWrapper

protected void setListModelWrapper(Object node,
                       ListModelWrapper wrapper)

clearListModelWrapper

protected void clearListModelWrapper(Object node)

clearAllListModelWrappers

protected void clearAllListModelWrappers()

initWrapper

protected void initWrapper(Object node)

createListModelWrapper

protected ListModelWrapper createListModelWrapper(Object node)

Creates an empty list model wrapper. Subclass can override this method to create their special list model wrapper. For example, FilterableTreeModel overrides it to create an instance of FilterableListModel. SortableTreeModel overrides it to create an instance of SortableListModel.

Default implementation of this method in this class simply returns a new instance of DefaultListModelWrapper.

Parameters:

node - the tree node

Returns:

an empty list model wrapper.

configureListModelWrapper

protected void configureListModelWrapper(ListModelWrapper wrapper,
                             Object node)

This is the method that will be called to configure the empty list model wrapper you created in createListModelWrapper(Object). Subclass can override it to configure the list model. For example, FilterableTreeModel uses this method to add filters that defined on FilterableTreeModel to FilterableListModel and turn those filters on.

In default implementation on DefaultTreeModelWrapper, this method is empty.

Parameters:

wrapper - the wrapper to be configured.

node - the tree node

valueForPathChanged

public void valueForPathChanged(TreePath path,
                       Object newValue)

Delegates to underlying tree model.

Specified by:

valueForPathChanged in interface TreeModel

Overrides:

valueForPathChanged in class AbstractTreeModel

Parameters:

path - the tree path

newValue - the new value

treeNodesChanged

public void treeNodesChanged(TreeModelEvent e)

Method for TreeModelListener. It will listen to the event from actual tree model and fire converted tree model for this tree model.

Specified by:

treeNodesChanged in interface TreeModelListener

Parameters:

e - the TreeModelEvent

treeNodesInserted

public void treeNodesInserted(TreeModelEvent e)

Method for TreeModelListener. It will listen to the event from actual tree model and fire converted tree model for this tree model.

Specified by:

treeNodesInserted in interface TreeModelListener

Parameters:

e - the TreeModelEvent

treeNodesRemoved

public void treeNodesRemoved(TreeModelEvent e)

Method for TreeModelListener. It will listen to the event from actual tree model and fire converted tree model for this tree model.

Specified by:

treeNodesRemoved in interface TreeModelListener

Parameters:

e - the TreeModelEvent

treeStructureChanged

public void treeStructureChanged(TreeModelEvent e)

Method for TreeModelListener. It will listen to the event from actual tree model and fire converted tree model for this tree model.

Specified by:

treeStructureChanged in interface TreeModelListener

Parameters:

e - the TreeModelEvent

convertTreeModelEvent

@Deprecated
protected TreeModelEvent convertTreeModelEvent(TreeModelEvent e)

Deprecated. replaced by convertTreeModelEvent(javax.swing.event.TreeModelEvent, int)

Converts the tree model event for the actual model to the event for this model.

Parameters:

e - the TreeModelEvent

Returns:

the tree model event for this model.

convertTreeModelEvent

protected TreeModelEvent convertTreeModelEvent(TreeModelEvent e,
                                   int eventType)

Converts the tree model event for the actual model to the event for this model.

Parameters:

e - the TreeModelEvent

eventType - the event type, EVENT_TYPE_NODES_INSERTED, EVENT_TYPE_NODES_REMOVED or EVENT_TYPE_NODES_CHANGED

Returns:

the tree model event for this model.
