GWT CellTree expand/collapse all

[Sven]

Hi there,

is there a simple way to just expand or collapse all treenodes?
Or do i really have iterate through each one and use setChildOpen?

Hope someone can help :)

public void TreeNodeExpand(TreeNode node) {

for (int i = 0; i < node.getChildCount(); i++) {

if (!node.isChildLeaf(i)) {

TreeNodeExpand(node.setChildOpen(i,

true));

}

}

}

public void TreeNodeCollapse(TreeNode node) {

for (int i = 0; i < node.getChildCount(); i++) {

if (!node.isChildLeaf(i)) {

TreeNodeExpand(node.setChildOpen(i,

false));

}

}

}
