- * @class Ext.ux.tree.TreeGridSorter

- * Provides sorting of nodes in a {@link Ext.ux.tree.TreeGrid}. The TreeGridSorter automatically monitors events on the
- * associated TreeGrid that might affect the tree's sort order (beforechildrenrendered, append, insert and textchange).
- * Example usage:
- *
- new Ext.ux.tree.TreeGridSorter(myTreeGrid, {
- folderSort: true,
- dir: "desc",
- sortType: function(node) {
- // sort by a custom, typed attribute:
- return parseInt(node.id, 10);
- }
- });

- * @constructor
- * @param {TreeGrid} tree
- * @param {Object} config
