no...you can check a node with setChecked but before is renderer and calling
it at construction.
but i'm not sure of it.
try this
TreeNode node = new TreeNode("checked_node") {
{
setChecked(true);
}
}
I have seen sometimes that this way is different than
TreeNode node = new TreeNode("checked_node");
node.setChecked(true);
In the sense that first function the second not!
(i saw with setExpanded)...
infact if you look at createNode of xmltreeloader
you'll see that every setter is called as in the first code.
