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.

getSelectedNodes

public List<N> getSelectedNodes()

Description copied from class: NavHelper

Obtains the selected nodes of the registred tree.

Specified by:

getSelectedNodes 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,
         boolean addOneClickSelectionListener,
         TreeSelectionListener listener,
         TreeWillExpandListener willExpandListener)

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 (if required) the NavHelper.selectionListener. Note : as a second side-effect, it will register the given willExpandListener (if not null) for the ui and do it BEFORE the NavHelper.expandListener. The main idea here is to be able to block any expand (or collapse).

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

addOneClickSelectionListener - a flag to expend when selection

listener - the optional selection listener to add

willExpandListener - the optional will expand listener to add BEFORE the default expand tree listener (if he was required)

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
