CheckBoxTree

[venkataratna]

Hi,

I am using CheckBoxTree.In this I am using two separate Functionalities.

1. Select the Tree Node
2. Check the Checkbox

Both Operations i am using different methods.

1. Select the Tree Node Purpose i am using

myCheckBoxTree.addTreeSelectionListener(new TreeSelectionListener() {
public void valueChanged(TreeSelectionEvent se) {

It is working fine.

2. Check the Checkbox purpose i am using

myCheckBoxTree.getCheckBoxTreeSelectionModel().addTreeSelectionListener(new TreeSelectionListener() {
public void valueChanged(TreeSelectionEvent e) {

But in this scenario issues are
1. Functionality is not working
2. When ever i clicked the checkbox at that time Tree Node also selecting (So, automatically, 1st Functionality i.e. Select the Tree Node) functionality is working.

I need whenever i select Checkbox at that time Tree Node Does not Select. Only Checkbox is Checked

But i wrote, 2nd Functionality i..e. Check the Checkbox functionality in
myCheckBoxTree.addTreeSelectionListener(new TreeSelectionListener() {
public void valueChanged(TreeSelectionEvent se) {

in this method,at that time functionality is working.

I need help of 2 Functionality scenarios 2 different Listener.

I saw your reply in this problem in below url

viewtopic.php?f=18&t=13541

But for me it is not working.

Even I tried addTreeCheckingListener(new TreeCheckingListener() {
public void valueChanged(TreeCheckingEvent e) {

It is not working.

Could you please give me the solutions.

Thanks,
Venkata.

It's wired. The two listeners should be independent. Here is a screencast of my test case http://screencast.com/t/Mflx3cjHfwN. Could you please share the test case for investigation?

Thanks,

Hi,

Thanks, For Reply. I wrote the code in same way (i.e. your video wise, i.e. Your URL)

1. myCheckBoxTree.getCheckBoxTreeSelectionModel().addTreeSelectionListener(new TreeSelectionListener() {
public void valueChanged(TreeSelectionEvent e) {
myMethod();
}
});

whenever i called this method it is not working.

2. myCheckBoxTree.addTreeSelectionListener(new TreeSelectionListener() {
public void valueChanged(TreeSelectionEvent e) {
myMethod();
}
});

In this scenario i called this method, it is working.


Even I tried one more condition in 2nd one. This time I am calling mymethod() in 1st one format.
i.e.

myCheckBoxTree.getCheckBoxTreeSelectionModel().addTreeSelectionListener(new TreeSelectionListener() {
public void valueChanged(TreeSelectionEvent e) {
myMethod();
}
});



myCheckBoxTree.addTreeSelectionListener(new TreeSelectionListener() {
public void valueChanged(TreeSelectionEvent e) {

if(myCheckBoxTree.isClickInCheckBoxOnly()){
// Here I wrote CheckBox Selected Condition
}

}
});

Could you please give me the solutions.

Thanks,
Venkata.

[JIDE Support]

Do you mean the listener was not triggered by "it is not working"? If it is the case, please share your standalone test case for us to investigate.

Hi,

Thank you for Reply.

I used two different Listeners but it is effecting on one on another.

When i click Check Box, Tree Node is highlighting and It is going to Tree Node Selecting Listeners Functionality.

How to rectify this issue.

Please give me the Solution.

Here i am Coping my Code.

It's wired. This test case works fine on our end. A screencast could be found at http://screencast.com/t/7XC6ayuSaa08.

Hi,

Thank you For reply.

In My PC Some Settings are problem.After that i tested this code in othe PC,at that time also it is worked.

I tested in windows 7 PC it is working fine.In this PC Java 6,Eclipse Helios and Eclipse Indigo.It is working fine.

But my PC is xp 32 bit,i am using Java 6,Eclipse Helios and Eclipse Indigo.Here it is not worked.

Could you tell me the Your tested Environment.


Thanks,
Venkata.

[JIDE Support]

Thanks for your clarification. The environment we tested was: Windows 7 x64, JSDK 6, Intellij IDEA 11.1.3. Will try to test it in Windows Xp 32 when we found one. And keep you posted when we have any progress.

Thanks,

i want to convert treepath to String and vice - versa. Please reply me ASAP.

because I am storing retrieved Treepaths in one of the columns of database in the TEXT format and then again fetching Sting to convert to TreePath.

E.g. - [[Condition, DIABETES], [Condition, HYPERTENSION], [Condition, HIV], [Condition, CHD, Angina]]

i want to individual store values in database in such format as below :

Condition, DIABETES
Condition, HYPERTENSION
Condition, HIV
Condition, CHD, Angina

and again fetch row to convert to treepath. Quick help would be appreciated.
Also reply the solution at my ID - ankursoni.leonardo@gmail.com

thanking you all.

[JIDE Support]

Looks like your request is about an ObjectConverter. There is no existing converter included in JIDE package. However, we do have some sample code in JIDE ExComboBoxDemo FYI.

Code: Select all

        ObjectConverterManager.registerConverter(TreePath.class, new ObjectConverter() {
            @Override
            public String toString(Object object, ConverterContext context) {
                return object == null ? "" : object.toString();
            }

            @Override
            public boolean supportToString(Object object, ConverterContext context) {
                return true;
            }

            @Override
            public Object fromString(String string, ConverterContext context) {
                if (string != null) {
                    String text = string.trim();
                    int n = text.indexOf("[");
                    if (n >= 0) {
                        text = text.substring(n);
                    }
                    if (text.startsWith("[") && text.endsWith("]")) {
                        String s = text.substring(1, text.length()-1);
                        String[] split = s.split(",");
                        Object[] nodes = new Object[split.length];
                        for (int i = 0; i < nodes.length; i++) {
                            nodes[i] = new DefaultMutableTreeNode(split[i]);
                        }
                        return new TreePath(split);
                    }
                }
                return null;
            }

            @Override
            public boolean supportFromString(String string, ConverterContext context) {
                return true;
            }
        }, new ConverterContext("TreePath"));


Thanks,

[ankur.leonardo]

thank you very much. I shall update my response when i implement it . JIDE Support team rocks !!

[ankur.leonardo]

I have already created Tree at the beginning, then i try to select the nodes which were present in the database as discussed in previous talks.

i used code like :

loop{
tree.getCheckBoxTreeSelectionModel()
.addSelectionPath(new TreePath(nodes));
}

but I am not able to see the tree selected in the GUI. Even though i properly get all the nodes in Treepath format as :
[Condition, CHD]
[Condition, HIV]

In case if you have doubt that what have i done to design GUI and place code , sending you my sample code :

CheckBoxTree tree= new CheckBoxTree(conditionsRoot);
tree.addMouseListener(new FilterClinicalDataConditionsListener(tree, conditionsRoot));
tree.getSelectionModel().setSelectionMode(TreeSelectionModel.DISCONTIGUOUS_TREE_SELECTION);
final ImageIcon leafIcon = new ImageIcon("middle.gif");
final DefaultTreeCellRenderer renderer = new DefaultTreeCellRenderer();
renderer.setClosedIcon(new ImageIcon("right.gif"));
renderer.setOpenIcon(new ImageIcon("down.gif"));
renderer.setLeafIcon(leafIcon);
tree.setCellRenderer(renderer);
tree.setFont(new Font("calibri", Font.PLAIN, 18));
tree.putClientProperty("JTree.lineStyle", "None");
tree.addTreeSelectionListener(new XListener(tree, root));
// **********************************************show checked nodes
// Your Code
for (int loop = 0; loop < nodes.length; loop++) {
nodes[loop] = new DefaultMutableTreeNode(split[loop]);
}
tree.getCheckBoxTreeSelectionModel().addSelectionPath(new TreePath(nodes));
}
}
final JScrollPane scrollPane = new JScrollPane(tree);
scrollPane.setBounds(labelX, 200, 325, 350);
scrollPane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED);
panel.add(scrollPane);


suggest me where m I getting wrong , whether at making nodes or diaplaying GUI.

[JIDE Support]

Please use the TreePath used by CheckBoxTree instead of a new TreePath instance. You could retrieve the TreePath instance in use by invoking JTree#getPathForRow()/getPathForLocation().

Thanks,

[ankur.leonardo]

JTree#getPathForRow()/getPathForLocation() i guess give exact path if you know. but what i am doing is retrieving random node from database. elaborate more how can i use it in my code.

thanks for reply.....
regards.

[JIDE Support]

Understand that you are recreating the entire tree. In this case, you might have to compare your new TreePath instance with the new JTree's TreePaths to find the correct instance. You then will be able to pass that correct instance to select it.

B.T.W., it's required by Swing DefaultTreeSelectionModel. If you use your newly created TreePath instance to make tree selection, it will also fail.

Thanks,

[ankur.leonardo]

tree.getCheckBoxTreeSelectionModel().addSelectionPath(tree.getPathForRow(2)); is not working for me i dont know why
when the tree gets display all options are unchecked.

kindly give the solution. URGENT.

[JIDE Support]

It's weird. Is it possible to share with us a test case for further investigation? You can also give the attached CheckBoxTreeDemo a try. In this demo I use the same code to select the third node.

Code: Select all
