Just a quick question/clarification about the current Tree in 1.3.
Is it correct that the AbstractTree only uses a TreeModel to gain
access to the root TreeNode?
Looking at the code in AbstractTree.java line 499:
// is root item created? (root item is null if the items have not
// been created yet, or the whole tree was dirty and
clearAllITem
// has been called
if (rootItem == null)
{
TreeNode rootNode =
(TreeNode)((TreeModel)getModelObject()).getRoot(); <!-- look here
if (rootNode != null)
{
if (isRootLess())
{
rootItem =
newTreeItem(rootNode, -1);
}
else
{
rootItem =
newTreeItem(rootNode, 0);
}
itemContainer.add(rootItem);
buildItemChildren(rootItem);
}
}
I tried to implement my own TreeModel but noticed that it only called
getRoot() and nothing else...
Is this the intended behavior?
Does this mean that I have to implement my own TreeNode to build a dynamic tree?
/Regards Mats
