CheckBoxTree-Need to display checkbox only for leaf nodes

[mandar.j]

Hi,

I am trying to use CheckBoxTree and in that I would like to display checkbox only for those nodes who don't have any child node i.e. only for leaf nodes. But somehow I am not getting how to set this behaviour. The nodes in tree who have child node should display as a normal folder(with expand capability) icon without checkbox for the same.

Any idea on how to achieve this behaviour?

Any help would be appreciated.

Code snippet:

Code: Select all

DefaultMutableTreeNode rootNode = new DefaultMutableTreeNode(nodeName);
DefaultMutableTreeNode childeNode1 = new DefaultMutableTreeNode(nodeName1);
DefaultMutableTreeNode childeNode2 = new DefaultMutableTreeNode(nodeName2);
DefaultMutableTreeNode grandChildeNode3 = new DefaultMutableTreeNode(nodeName3);

rootNode.add(childeNode1);
rootNode.add(childeNode2);
childeNode2.add(grandChildeNode3);

CheckBoxTree tree = new CheckBoxTree(rootNode);

Thanks,
Mandar

Please give the following code a try.

Code: Select all

        _tree = new CheckBoxTree(treeModel) {
            @Override
            public boolean isCheckBoxVisible(TreePath path) {
                return ((DefaultMutableTreeNode) path.getLastPathComponent()).isLeaf();
            }
        };


Thanks,

Hello I use the JIDE Package to create a JTree with Checkbox, i want that only one leaf node have to be checked at the same time( that mean the leaf node work like radio button). The parent of the leaf node can be arbitrary checked. can anybody help me?

Please invoke yourCheckBoxTree.getCheckBoxTreeSelectionModel().addTreeSelectionListener() to perform your logic in the listener.

B.T.W., please try to create a separate thread when you want to start a new inquiry.

Hello,
sorry the next Time I will create a new Inquiry.
Please can you more explain how I can use the CheckBoxTree.getCheckBoxTreeSelectionModel().addTreeSelectionListener(). I use it but I get the list of Path for all Checked Button, or the last selectedNode. My idea was when a leafnode is selected look at other children of the parent node and if one is checked, i have to unchecked it. But which method can i use to checked that the children of a node are selected or not? and which method can I use to unchecked it?

Thanks in advance for your help.

In that listener, please do the following:
1, keep the current selection you want to keep, for example, the last selected leaf node.
2, remove this listener, just to avoid the following steps cause endless loop.
3, clear all selections with CheckBoxTreeSelectionModel#clearSelection().
4, add the selection you kept in step 1 back with CheckBoxTreeSelectionModel#addSelectionPaths().
5, add this listener back again for future use.
