How to do SelectAll() when during JTree node edit?
This question's been asked a few times but the answers haven't been very clear ( or the code that was posted was broken, etc. )
I have a JTree -- when the user edits a node, I want to initially select all the text in the .that node.
Does anyone have a SIMPLE, COMPLETE extension of a DefaultTreeCellEditor which does this? If so, please post. -- No fancy bells or whistles.
Thanks much.
...well, there is a very easy, but not clean way to do it:
* Configures the editor. Passed onto the <code>realEditor</code>.
public Component getTreeCellEditorComponent(JTree tree, Object value, boolean isSelected, boolean expanded, boolean leaf, int row) {
DefaultTreeCellEditor.EditorContainer comp= (EditorContainer) super.getTreeCellEditorComponent(tree, value, isSelected, expanded, leaf, row);
JTextField textField= (JTextField) comp.getComponent(0);
textField.setSelectionStart(0);
textField.setSelectionEnd(textField.getText().length());
return comp;
}This will work if you click the node twice and wait to call the editor, however most users will start editing a TreeNode by clicking multiplely on the node - as the Editor is a normal TextField, it will lose it's selection when being clicked upon. If this is a problem for you, just overwrite DefaultTreeCellEditor.DefaultTextField's processMouseEvent(MouseEvent) method and decide whether the click should remove the selection or not.
I guess if you ask for a piece of code which will keep the text selected you have something special in mind to do with the editor, so sample code wouldn't do you much good here. Get back to me if you have trouble intercepting the mouse event.

How to change icons of a JTree node dynamically
Hi all!
I want to change icon associated with a node dynamically ( i.e. after the tree has being displayed). How can i achieve this?
Can any one provide me a sample code snippet.
Thanks in advance
MuraliI have created CustomCellRenderer and i'm calling this class as follows
tree.setCellRenderer((TreeCellRenderer) new CustomCellRenderer(true));
The boolean value for the constructor (in this case it's true) will be set to
a local variable in the CustomCellRenderer class. Then upon clicking a node in the tree the boolean value (true) is set and the icon for that node should be changed as specified in the CustomCellRenderer class.
When i click on a node all the icons of that tree are disappearing.
Can any one help me in this issue
public class CustomCellRenderer

How to generate event from a JTree node
I plan to move a vector list to a JTree and then make it possible to launch an even by double clicking a node in the tree, how can i quicly achieve that cuz i have being trying to overcome that since...any assistance?
ThanksSince TreeNodes are no Components you have to add a MouseListener to your JTree and use the JTree.getPathForLocation(int x, int y) method to get the TreePath. something like this should work for you:
tree.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (e.getClickCount != 2) return
JTree tree = (JTree)e.getSource();
TreePath path = tree.getPathForLocation(e.getX(), e.getY());
TreeNode node = (TreeNode)path.getLastPathComponent();
Do whatever you want here
Hope that helps, Mathias -
How to move focus from one JTree node to another one and then back again?
Hi all!
Say I have a very simple JTree
package main;

import java.awt.Container;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextField;
import javax.swing.JTree;
import javax.swing.event.TreeSelectionEvent;
import javax.swing.event.TreeSelectionListener;
import javax.swing.tree.DefaultMutableTreeNode;
public class SelectableTree extends JFrame implements TreeSelectionListener {
public static void main(String[] args) {
new SelectableTree();
private JTree tree;
private JTextField currentSelectionField;
public SelectableTree() {
super("JTree Selections");
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent event) {
System.exit(0);
Container content = getContentPane();
DefaultMutableTreeNode root = new DefaultMutableTreeNode("Root");
DefaultMutableTreeNode child;
DefaultMutableTreeNode grandChild;
for (int childIndex = 1; childIndex < 4; childIndex++) {
child = new DefaultMutableTreeNode("Child " + childIndex);
root.add(child);
for (int grandChildIndex = 1; grandChildIndex < 4; grandChildIndex++) {
grandChild = new DefaultMutableTreeNode("Grandchild "
+ childIndex + "." + grandChildIndex);
child.add(grandChild);
tree = new JTree(root);
tree.addTreeSelectionListener(this);
content.add(new JScrollPane(tree), BorderLayout.CENTER);
currentSelectionField = new JTextField("Current Selection: NONE");
content.add(currentSelectionField, BorderLayout.SOUTH);
setSize(250, 275);
setVisible(true);
public void valueChanged(TreeSelectionEvent event) {
currentSelectionField.setText("Current Selection: "
+ tree.getLastSelectedPathComponent().toString());
}All I need is to move focus from currently selected node, to some other node (does not matter which one), then to "sleep" for a second and finally move it back to return selection to the previously selected node. The only question is how do I do this?Use a Seperate Thread to do it:
Runnable r = new Runnable() {
public void run() {
int k=tree.getSelectionRows()[0];
DefaultMutableTreeNode node = (DefaultMutableTreeNode)tree.getLastSelectedPathComponent();
if(node.getNextSibling()!=null)
tree.setSelectionRow(k+1);
else
tree.setSelectionRow(k-1);
sleepe(k);
public void sleepe(int i){
try{
Thread.sleep(1000);
}catch(Exception e){
e.printStackTrace();
tree.setSelectionRow(i);
}Then start this thread in a mouse click event(or any other similar),but not in TableSelectionListener because >>if the current selected row is 1 then it will execute the valueChanged method of TableSe..li. and we set the selected row to 2 then again it will execute the valueChanged method of TableSe..li.It will repeat till something,or in error.
tree.addMouseListener( new MouseListener(){
public void mouseClicked(MouseEvent e) {
new Thread(r).start();
public void mouseEntered(MouseEvent e) {
public void mouseExited(MouseEvent e) {
public void mousePressed(MouseEvent e) {
public void mouseReleased(MouseEvent e) {
});Note:it worked perfectly for me. So add all the above in the right place and import necessary.It will execute perfectly. -
SPM 2.1 Scheduling Option - Daily. How can I control when during the day?
Hi All,
I understand that when you enable the "scheduling" option in the report, the report runs in the background and this caches the data to table opmdm_precalc_a.
You can set scheduling to daily or weekly runs. The weekly load can be set in the "Application Properties" menu e.g. to Sunday.
If I chose "daily", what time is it run then? The same time as the alert in "Application Properties"?
I've had a quick look at OPM* and RSXA* tables but couldnt see anything obvious as a clue.
Many thanks for any help
NeilHi Neil,
Yes, you are right. The time of execution is the same as the one for alerts.

Set different color for one JTree node
hello,
I managed to find how to set a color for Jtree nodes but the problem is that with my method all the nodes will b the same color whereas i'm looking to have nodes of different color depending on the situation.
the method for setting all Jtree nodes the same color(other than black):
tree.setCellRenderer(
new DefaultTreeCellRenderer() {
public Color getTextNonSelectionColor() {
return Color.lightGray; } });I WANT TO CHOSSE EACH COLOR FOR EACH NODE
help plz
thanksYou need to implement TreeCellRenderer interface
public Component getTreeCellRendererComponent(JTree tree,
Object value,
boolean sel,
boolean expanded,
boolean leaf,
int row,
boolean hasFocus)You can know which node is rendering by check value argument. Please read DefaultTreeCellRenderer's code. -
Xml in JTree: how to not collpase JTree node, when renaming XML Node.
Hi.
I'm writing some kind of XML editor. I want to view my XML document in JTree and make user able to edit contents of XML. I made my own TreeModel for JTree, which straight accesses XML DOM, produced by Xerces. Using DOM Events, I made good-looking JTree updates without collapsing JTree on inserting or removing XML nodes.
But there is a problem. I need to produce to user some method of renaming nodes. As I know, there is no way to rename node in w3c DOM. So I create new one with new name and copy all children and attributes to it. But in this way I got a new object of XML Node instead of renamed one. And I need to initiate rebuilding (treeStructureChanged event) of JTree structure. Renamed node collapses. If I use treeNodesChanged event (no rebuilding, just changes string view of JTree node), then when I try to operate with renamed node again, exception will be throwed.
Is there some way to rename nodes in my program without collpasing JTree?
I'am new to Java. Maybe there is a method in Xerces DOM implementation to rename nodes without recreating?
Thanks in advance.I assume that "rename" means to change the element name? Anyway your question seems to be "When I add a node to a JTree, how do I make sure it is expanded?" This is completely concerned with Swing, so it might have been better to post it in the Swing forum, but if it were me I would do this:
1. Copy the XML document into a JTree.
2. Allow the user to edit the document. Don't attempt to keep an XML document or DOM synchronized with the contents of the JTree.
3. On request of the user, copy the JTree back to a new XML document.
This way you can "rename" things to the user's heart's content without having the problem you described. -
Now, I want to sort tree node by increasing.
for example there are three child node:
[20 -40][
10 - 20]
[30- 60].
they are added to JTree node by different order.but are shown in increasingorder.
like this:
[10 - 20]
[20 -40][
[30- 60].
how to control tree node.Implement the Comparable interface in t he userobject class and possibly the toString(0 as well.
Ex.
public class UserObject implements java.lang.Comparable{
public int compareTo(Object obj) throws ClassCastException

How can i control which iView gets updated when a nav node gets clicked?
Hello,
Following setting: the content area of the desktop inner page inside the default frameworkpage usually consist of just one iView.
But what happens when there are 3 iViews inside? How do i have to call the pageloader which of the 3 iViews should get updated when a nav node of the detailed navigation is clicked?
ThanxHi
Since you will be using the Merger Id property, they will be linked to a single link in navigational area.
Refreshing a page / clicking the link in navigation Pane will result in refreshing of all the iViews.

When a context node use non-singleton, how to invoke the supply funtion eve
when a context node use non-singleton, how to invoke the supply funtion everytime the lead selection is changed ?
Hi wei,
<b>Non-singleton nodes:</b>
Web Dynpro allows you to define non-singleton nodes. Each non-singleton node has one node instance for each node element of the parent collection at runtime. The advantage is that each instance can be accessed directly. When using non-singleton nodes, the nodes are only created when the node values are retrieved. This can save resources that otherwise would slow down the performance of the application.
<b>Supply function:</b>
The Web Dynpro tools also automatically enhance the corresponding controller class with a supply function including the user coding area contained in it
Supply functions are implemented as methods of type
<b>public void supplyChildNodeElements(SomeChildNode node,
SomeParentNodeElement)</b>
in a Web Dynpro controller (view controller or custom controller). Supply functions and context nodes have a 1..1 relationship, that is, supply functions are specific for individual context nodes. Under certain conditions, supply functions are called by pages in the Web Dynpro runtime environment.
Hope this helps u,

Parse and display xml doc when click on JTree node?
Ok so here is the code that I have now. You will have to make alot of html files to run the program, but they can be empty for now. What you can do is just put the same exact html file to be displayed in each node element. for example.
DefaultMutableTreeNode n1_node1_b1 =
new DefaultMutableTreeNode(new ModuleInfo("Device", "device.html"));could be changed to
DefaultMutableTreeNode n1_node1_b1 =
new DefaultMutableTreeNode(new ModuleInfo("Device", "status.html"));And just keep adding the status.html page to each one of the nodes.
anyway.
For now when I click on the node, the html file is displayed in the JScrollPane rPane = new JScrollPane(htmlPane); and the htmlPane is a JEditorPane
what I need it to do.
When I click on the JTree node. I would like to go out to an xml file, parse the information in it, and display it to the pane.
I will need to later, be able to add, edit, or delete information on the xml through the pane later.

How to post an Event (mouse left click) to JTree node
Hi,
I am using JTree for my application just like the windows explorer tree. By default, Jtree node will got focus using left click.

How to hide node handles (legs) from JTree nodes?
Hello,
Does anyone has an idea on how to not display JTree node handles (legs)?
Thank you,
MindaugasYou can do it with Java/Metal look and feel by doing this:
JTree tree = new JTree(...);
tree.setClientProperty("JTree.lineStyle", "None");
For any other L&F, you will have to look at the UI code.
