setSelectionPath

public void setSelectionPath(TreePath path)

Specified by:

setSelectionPath in class NavHelper<DefaultTreeModel,JTree,NavTreeBridge<N extends NavTreeNode<N>>,N extends NavTreeNode<N>>

getSelectionModel

public TreeSelectionModel getSelectionModel()

Specified by:

getSelectionModel in class NavHelper<DefaultTreeModel,JTree,NavTreeBridge<N extends NavTreeNode<N>>,N extends NavTreeNode<N>>

isExpanded

public boolean isExpanded(TreePath pathToExpand)

Specified by:

isExpanded in class NavHelper<DefaultTreeModel,JTree,NavTreeBridge<N extends NavTreeNode<N>>,N extends NavTreeNode<N>>

expandPath

public void expandPath(TreePath pathToExpand)

Specified by:

expandPath in class NavHelper<DefaultTreeModel,JTree,NavTreeBridge<N extends NavTreeNode<N>>,N extends NavTreeNode<N>>

getTreeCellRenderer

public AbstractNavTreeCellRenderer<DefaultTreeModel,N> getTreeCellRenderer()

Description copied from class: NavHelper

Obtains the AbstractNavTreeCellRenderer renderer of the registred tree.

Specified by:

getTreeCellRenderer in class NavHelper<DefaultTreeModel,JTree,NavTreeBridge<N extends NavTreeNode<N>>,N extends NavTreeNode<N>>

Returns:

the renderer of the registred tree or null if no tree was registred nor the renderer is a AbstractNavTreeCellRenderer.

getSelectedNode

public N getSelectedNode()

Description copied from class: NavHelper

Obtains the selected node of the registred tree.

Specified by:

getSelectedNode in class NavHelper<DefaultTreeModel,JTree,NavTreeBridge<N extends NavTreeNode<N>>,N extends NavTreeNode<N>>

Returns:

the selected tree or null if no registred tree nor selection empty.

setUI

public void setUI(JTree tree,
                  boolean addExpandTreeListener,
                  TreeSelectionListener listener)

Description copied from class: NavHelper

Registers the given tree for this helper.

Note: as a side-effect, it will register (if required) the NavHelper.expandListener listener and the NavHelper.selectionListener.

Specified by:

setUI in class NavHelper<DefaultTreeModel,JTree,NavTreeBridge<N extends NavTreeNode<N>>,N extends NavTreeNode<N>>

Parameters:

tree - the tree to register

addExpandTreeListener - a flag to add expand listener

listener - the optional selection listener to add

createModel

protected DefaultTreeModel createModel(N node,
                                       Object... extraArgs)

Description copied from class: NavHelper

Register a new root node.

If internal NavHelper.getModel() does not exists, creates a new one from his given root node, otherwise just set the new root on the existing model.

Note: As a side-effect, the model will be keep in field NavHelper.getModel() and the NavHelper.treeModelListener will be registred on this model.

Specified by:

createModel in class NavHelper<DefaultTreeModel,JTree,NavTreeBridge<N extends NavTreeNode<N>>,N extends NavTreeNode<N>>

Parameters:

node - the root node of the new model

extraArgs - extra args to create initial model

Returns:

the new model
