Returns
Nothing.
Description
Method; specifies whether the node has a folder icon and expander arrow and either has children
or can have children. A node is automatically set as a branch when it has children; you only need
to call
setIsBranch() when you want to create an empty folder. You may want to create
branches that don’t yet have children if, for example, you only want child nodes to load when a
user opens a folder.
Calling
setIsBranch() refreshes any views.
Example
The following code makes a node of myTree a branch:
myTree.setIsBranch(myTree.getTreeNodeAt(1), true);
Tree.setIsOpen()
