Andrea, It's good to be careful with getting info back from widgets like that. If the widget is not yet rendered you will get a very nasty general error (yellow triangle).
If you need that info and you are not certain the component will have been rendered by that time, it's often best to keep collections of objects on your own of the tree node references. -kornel On Mon, Jul 6, 2009 at 10:30 AM, Roundcrisis <[email protected]> wrote: > Yeah that does work thanks :D > Andrea > > > > > On Mon, Jul 6, 2009 at 12:57 PM, Patrizio De Michele > <[email protected]>wrote: > >> hi, >> maybe you can use this code, try it and make me know: >> >> final List<Node> checkedNodes = new ArrayList<Node>(); >> final List<Node> allNodes = new ArrayList<Node>(); >> treePanel.getRootNode().cascade(new NodeTraversalCallback() { >> public boolean execute(Node node) { >> if (Boolean.valueOf(node.getAttribute("checked"))) { >> checkedNodes.add(node); >> } >> allNodes.add(node); >> return true; >> } >> }); >> >> bye Patrizio >> >> >> 2009/7/6 Andrea <[email protected]> >> >> >>> Hi there >>> >>> I m using a TreePanel that can be checked; and was wondering what is >>> the best way to get info back from the tree: ie all nodes whether they >>> are checked or not , and I would like to know if they are. >>> >>> I know i can use treePanel.getChecked() but that only gets me the >>> checked ones >>> or I can use root.getChildNodes() but here I m not terribly sure how >>> to know if its checked or not, it also seems quite cumbersome to >>> navigate the tree structure this way >>> >>> any other alternatives? or recomended way to deal with trees in >>> general? >>> >>> >>> Thanks >>> >>> >> >> >> > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "GWT-Ext Developer Forum" group.
