Availability

Flash Player 6 (6.0.79.0).

Edition

Flash MX Professional 2004.

Usage

treeInstance.getIsBranch(node)

Parameters

node An XMLNode object.

Returns

A Boolean value that indicates whether the node is a branch (true) or not (false).

Description

Method; indicates whether the specified node has a folder icon and expander arrow (and is therefore a branch). This is set automatically when children are added to the node. You only need to call Tree.setIsBranch() to create empty folders.

Example

The following example creates two nodes in a tree and calls isBranch() to determine whether the second one is a branch.

You must first add an instance of the Tree component to the Stage and name it my_tr; then add the following code to Frame 1.

/**
 Requires:
  - Tree component on Stage (instance name: my_tr)
*/

var my_tr:mx.controls.Tree;

my_tr.setSize(200, 100);

var trDP_xml:XML = new XML("<node label='1st Local Folders'><node label='Inbox' data='0' /><node label='Outbox' data='1' /></node><node label='2nd Local Folders'><node label='Inbox' data='2' /><node label='Outbox' data='3' /></node>");
my_tr.dataProvider = trDP_xml;

var isBranch:Boolean = my_tr.getIsBranch(my_tr.getTreeNodeAt(1));
trace("2nd node is a branch: " + isBranch);
