How to select node in JTree without firing event?

I have got standard situation. JTree in the left panel, and several edit boxes in right panel. Certainly, I have TreeSelectionListener, which on every tree node selection shows corresponding model values in edit boxes.
I'd like to implement next logic:
1. Something was changed in any edit box in right panel. Model has been changed.
2. User clicks on different node in tree.
3. Dialog "Message was not saved. Save?" with Yes/No/Cancel buttons are shown.
Yes/No buttons are easy to handle.
Question is about Cancel. I'd like on Cancel button left all edit boxes in their present state (do not restore values from saved model) and select back node, which wasn't saved.
Problem is next. If I select node by setSelectionPath or smth like that, but... JTree fires event and my listener receives onTreeItemSelected back, which checks that node wasn't saved and ......
Who does have any idea, or have done similar tasks? How can I select node and do not allow tree fire event this time?
Thanks in advance.

First, as soon as the model changes (when editing any
combo box) some flag will be set. Now the logic which
updates the combo boxes will do it only on a change of
the current node and (this is new) if the flag wasn't
set. You should have some flag anyway because somehow
you must determine when to show the dialog, shouldn't
you?Yes, I have got this logic implemented. But it's only the half :)
I know exactly when my model has been changed, but if it was changed, i'd like to ask user what to do next - svae/loose changes/cancel
And on cancel i'd like to select last edited tree node and do not get event from tree at that moment.
>
Second way, prevent selecting a new node if that flag
has been set. You could do this by subclassing
DefaultTreeSelectionModel and overriding some methods
(setSelectionPath() et al).Ok. I'll investigate this.

Setting custom color for selected node in JTree?

Hi,
i want to set my own color for selected node in JTree. i don't want to set for all the nodes...how to set Color for Selected node using TreeCellRender class?
Thanks
Mani

I assume you are not setting a custom tree cell renderer...
javax.swing.JTree theTree = ...;
java.awt.Color newBGColor = ...;
((javax.swing.tree.DefaultTreeCellRenderer)theTree.getCellRenderer())
.setBackgroundSelectionColor(newColor);

Change icon of a non selected node in JTree

Hello
I have a swing application contening a JTree.
I'd like to know how to change the icon of a non selected node in my tree. I have the information about the node and its path. I try to change userObject information and the icon of the node with the setIcon of (DefaultMutableTreeNode), and reload the node (DefaultTreeModel) but it doesn't work.
Do I have to set the change in my CellRenderer ?
Any advice will be welcome
Anne

If you carefully look at the java tutorial tree, the change is made for all the leaf icon. What I want is to change the icon of a not selected node of my tree while I do other stuff with the other nodes like select, display their contents, drag them ...
the operation of a not selected node is independant from the selection in the tree.
So I still ask how to force a node to reload and take care of the change of his icon.

Coloring selected nodes in JTree

i am currently using setCellRenderer() for highlighting a selected node in my JTree.but when i select another node, the previously selected node loses its highlight.i would like to know of how i could make the highlight in the selected nodes remain persistent.

I am currently using DISCONTIGUOUS_TREE_SELECTION only. my requirement is that i should be able to select any number of nodes.so i use this selection.
but at the same time, my highlight in selected nodes should be like a toggle-state.
if i select an already selected node ( say A), the highlight has to go away.
and at the same time, th highlight on previously selected nodes (say B, C) should be persistent.
am currently using TreeSelectionListener. and for rendering am using SetCellRenderer.
in this scenario, how could my work be accomplished?

How to add nodes to JTree???

Hi ,

I know how to add the customized code to the JTree, but while adding following code to the JMenuItem's Click, does'nt work
Code :
private void jMenu1ActionPerformed(java.awt.event.ActionEvent evt)
                   DefaultMutableTreeNode dm =new DefaultMutableTreeNode("Root Element");
                   dm.add(new DefaultMutableTreeNode("Child Node"));
                   Treeview=new javax.swing.JTree(dm);
}        Please help me out where i should write the code so that it will add the nodes to the JTree on JMenuItem's Click.
Thanks in Advance

How to show only all children of selected node in JTree??

Dear friends:
I have Two Panels, PA and PB,
PA has a Jtree as code below, and PB listens to PA,
I hope to do following,
If I select a node called A in PA, then Node A's all children such as A1, A2, A3 will be displayed in PB, but not display A1, A2, A3's children such as A3 has C1, C2, C3, C4 & C5, until I select A3 then PB will display only all A3's children: C1, C2, C3, C4 & C5;
i.e, only populate each ONE level of children of Node A or any node I select, not its grandchildren and its grand-grand children;
Please help how to do it??
I tried amny times, failed.
Thanks

     for (i = 0; i < childNodeCount; i++) {
          results.add(parent, i);

How to rename node in JTree?(URGENT)

Hi,all:
I am facing a renaming problem in JTree. After I rename, the node still remain the old name, Could anybody tell me why and how to solve it?
The piece of code is as follow:
JTextField textField = new JTextField();
newDndTree.setCellEditor(new MyCellEditor(newDndTree,textField));
newDndTree.setEditable(true);
class MyCellEditor extends DefaultCellEditor {
private JTree tree;
public MyCellEditor(JTree tree, JTextField text) {
super(text);
this.tree = tree;
public boolean isCellEditable(EventObject e) {
boolean rv = false; // return value
if(e instanceof MouseEvent) {
MouseEvent me = (MouseEvent)e;
if(me.getClickCount() == 3) {
TreePath path =
tree.getPathForLocation(me.getX(), me.getY());
if(path.getPathCount() == 1) // root node
return false;
DefaultMutableTreeNode node =
(DefaultMutableTreeNode) path.getLastPathComponent();
Object hitObject=path.getLastPathComponent();
if(hitObject instanceof TreeNode)
return (((TreeNode)hitObject).isLeaf());
return (false);

Hi,all:
My problem is it doesn't rename the node, the node remain the old name.
My piece of code as follow:
//Set Cell Editor
newDndTree.setCellEditor(new MyCellEditor());

public MyCellEditor() {
super(new JTextField());
public boolean isCellEditable(EventObject e) {

if(me.getClickCount() == 3) {
JTree tree = (JTree)me.getSource();
TreePath path = tree.getPathForLocation(me.getX(), me.getY());
if(path.getPathCount() == 1) {
//System.out.println("Root");
return false; // root node
DefaultMutableTreeNode node =
(DefaultMutableTreeNode) path.getLastPathComponent();
Object hitObject=path.getLastPathComponent();

How to select nodes for passing to a template

How can I write an xpath to select only the row contained in rowset that has a child node language with the value of en-us
ie something like
select=rowset/row where rowset/row/child='en-us'
Tks
Rob

Assuming that your xml looks like:
<rowset>
<row>
<language>en-us</language>
:Then it would be:
select="rowset/row[language='en-us']"
For a good introduction and tutorial to XML, XPath and XSLT, among other things, you can check out my book Building Oracle XML Applications.

How to select a small area without a low feather???

When i select a small area with the lasso tool i get the warning: 'no pixels are more than 50% selected. The selected edge will not be visible.'
I already read that the feather should me low. However if i do that, the outcome wont be nice.
I want to bleach teeth and when i use a small feather the teeth wont be selected very well. So how can i solve this problem??
(I am sorry if my english is not that well, i am from the Netherlands )
I hope someone can help me with this.
greetings stephanie

You can use the lasso tool without any Feather (set feather to 0) keep anti-alias checked and use Refine Edge to add any feathering if needed.
You might make a layer mask from the selection and then use the brush tool to refine the mask.
When you get that message you still have a selection, but elements is letting you know that any pixels selected less than 50% won't be visible with the marching ants. (the selection edge you see
when using any of the selection tools)
What version of photoshop elements are you using?

JTree: How to get the currently selected node

How do I get the currently selected node in JTree?
getLastSelectedPathComponent() this method always return the last selected node and not the current one.
Thanks in advance
Sachin

Use
TreePath selectedPath = tree.getSelectionPath()If your tree allows multiple selections, use
TreePath [] selectedPaths = tree.getSelectionPaths() this will return an array of all selected tree paths.
Once you get the tree path, call the treePath.getLastPathComponent(). this should tell you the currently selected node.
Hope this helps

How could i get the selected node in the JTree

getLastSelectedPathComponent() �returns the parent node of currenr selected, so how could I get the selected node itself in the JTree
I will appretiate for any help!

i think you can get by....
TreePath treePath = tree.getSelectionPath();
DefaultMutableTreeNode treeNode = (DefaultMutableTreeNode) treePath.getLastPathComponent();

Perform drag&drop in Jtree without even selecting a node once?

Hi All,
Is it possible to perform drag and Drop action on tree nodes even when the Jtree is not active.
That is, say a jtree is not active and i directly want to drag a node inside it without even selecting it once?
Thanks alot in Advance.

You should google for "jtree drag and drop". I remember seeing a very nice tutorial on codeproject.
If your run into any specific issue let me know.
