Hi Patrizio:
Thanks for the answer however I do need to do the cascade onCheckChange
because I need to set the child of the node to whatever the current checked
value of the parent is
I tried this
public void onCheckChange(TreeNode node, final boolean checked) {
for (Node temp: node.getChildNodes()){
((TreeNode)temp).setChecked(checked);
System.out.println(temp.getPath());
}
}
and that does print the right nodes to console , however it doesnt check :(
so then I tried the cascade that I posted earlier and on that you hit the
problem that cascadeing does transverse the whole tree,
however I thought the setChecked would work, and it doesnt.
So I tried to call execute of the cascade with a TreeNode as parameter, but
you cant, because of the cascade interface sets the parameter to be a Node .
It seems like this is a bug
If anyone knows a work around to set the child of a node as checked I would
be very thankful :D
