Method Detail

isNodeSibling

public static boolean isNodeSibling(javax.swing.tree.TreeModel treeModel,
                                    java.lang.Object node,
                                    java.lang.Object siblingNode)

getPathToRoot

public static java.lang.Object[] getPathToRoot(javax.swing.tree.TreeModel treeModel,
                                               java.lang.Object node)

Searches the entire tree model for the node's path to the root. Used when there might be more than one match.

Parameters:

treeModel - the model to be searched

node - the node to search for

Returns:

the array of tree objects showing the path

getPathToRoot

public static java.lang.Object[] getPathToRoot(javax.swing.tree.TreeModel treeModel,
                                               java.lang.Object node,
                                               boolean findFirstMatch)

Searches a tree model for a node's path to the tree root.

Parameters:

treeModel - the model to be searched

node - the node to search for

findFirstMatch - specifies whether to stop the search on the first match

Returns:

the array of tree objects showing the path

expandAllNodes

public static void expandAllNodes(javax.swing.JTree tree)

expandTreeToLevel

public static void expandTreeToLevel(javax.swing.JTree tree,
                                     int level)
