Interface TreeWidget.Nodes

Enclosing class:

TreeWidget

public static interface TreeWidget.Nodes

Structured data for Tree Widget. Example of tree data:

 Object[] root = {
         "root", "leaf 0", // { 0 }
         "leaf 1", // { 1 }
         new Object[] {
                 "branch 2", "leaf 2-0", // { 2, 0 }
                 "leaf 2-1" }, // { 2, 1 }
         new Object[] {
                 "branch 3", new Object[] {
                         "branch 3-0", "leaf 3-0-0" }, // { 3, 0, 0 }
                 "leaf 3-1" }, // { 3, 1 }
         "leaf 4" }; // { 4 }
 

Assume the node value of leaf node '2-1' is '48', 'getIndices(48)' returns an array '{ 2, 1 }'. 'getValue( { 2, 1 } )' returns '48'.
