Can not highlight a JTree node programmatically

Hi Swing lovers,
I can select a node using setSelectionPath. Unfortunately I can not find a way to show the user that the node is selected. I know it can be done. When traversing the tree with the up- and down keyboard arrow, it shows what I want to see.
Am I overlooking some method here?
Thanks a lot for the tip,
Erik

Thanks DrClap,
I expected to find an easy way to mark a jTree node as being selected. However the TreeCellRenderer does the job. See the code snipped below:
public JTree jTree1 = new JTree();
private TreeNode currentNode = null;
//assing currentNode somewhere in you code
jTree1.setCellRenderer(new MyRenderer());
private class MyRenderer extends DefaultTreeCellRenderer {
    public MyRenderer() {
    public Component getTreeCellRendererComponent(
                            JTree tree,
                            Object value,
                            boolean sel,
                            boolean expanded,
                            boolean leaf,
                            int row,
                            boolean hasFocus) {
      if (currentNode != null) {
        if (value.hashCode() == currentNode.hashCode()) sel = true;
    super.getTreeCellRendererComponent(
                            tree, value, sel,
                            expanded, leaf, row,
                            hasFocus);
    return this;

How to highlight a tree node programmatically

Problem
=====
Just like a typical management software, I have a navigation tree presenting a list of objects (let's say toasters) on the left panel. The content panel on the right side presents the details of a toaster, when the user selects the toaster on the navigation tree. On the toaster details panel, I would like to have a hyper link referring to another toaster - associated to the selected toaster. On clicking on the hyperlink, I would like to display the details of the associated toaster and the navigation tree node for the associated toaster being highlighted.
For example, BUI presents the following now:
+ Toasters | Toaster 1 Details [Refresh]
+ <toaster1> |
+ toaster2 | ... toaster3
+ toaster3 |
toaster1 is selected on the navigation tree. The contents panel displays Toaster 1 details, which has a hyper link for toaster3.
When the user click on toster3 on the contents panel, I would like to see the following
+ Toasters | Toaster 3 Details [Refresh]
+ toaster1 |
+ toaster2 | ...
+ <toaster3> |
My Trial
=====
ADF Rich Client 11.1.2.3 is used for my development.
Jspx code for the navigation tree looks like this:
<af:tree id="navTree" ...>
<f:facet name="nodeStamp">
<af:panelGroupLayout id="nodePgl">
<af:switcher facetName="#{stamp.outcome!=null?'actnode':'noactnode'}" ...>
<f:facet name="actnode">
<af:commandLink id="leafLink" text="#{stamp.label}" action="#{stamp.actionOutcome}">
<af:setActionListener from="#{stamp.key}" to="#{treeHandler.selectedMenuItem}"/>
</af:commandLink>
</f:facet>
<f:facet name="noactnode">
<af:outputText id="notLeafText" value="#{stamp.label}"/>
</f:facet>
</af:switcher>
</af:panelGroupLayout>
</f:facet>
</af:tree>
The hyper link on the contents panel looks like this:
<af:iterator var="toaster" value="#{toastData.toasters}">
<af:commandLink text="#{toaster}" action="#{toasterHandler.goToToaster}">
<f:param name="toasterId" value="#{toaster}"/>
<af:setActionListener from="#{toaster}" to="#{treeHandler.selectedToaster}"/>
</af:commandLink>
</af:iterator>
I got some tips from this forum (cannot find thread at the moment) and implemented the treeHandler.selectedToaster method as follows:
// getSelectionState returns selStat, which is instantiated like the following:
// RowKeySet selStat = new RowKeySetTreeImpl();
// TreeModel model = (TreeModel) menuModel.getWrappedData();
// selStat.setCollectionModel(model);
// selStat.setContained(true);
RowKeySet rowKeySet = getSelectionState();
rowKeySet.removeAll();
// synthesize the rowKey for the selected toaster
// if the toaster found in the toaster node list,
// rowKey should look like [0, <rowIdx of toaster>]
ArrayList<Integer> rowKey = new ArrayList<Integer>();
rowKey.add(0);
rowKey.add(new Integer(rowIdx));
TreeModel model = (TreeModel) menuModel.getWrappedData();
model.setRowKey(rowKey);
model.setRowIndex(rowIdx);
rowKeySet.add();
This seems to work most of times except when I refresh the contents details panel using partial page rendering.
I get NullPointerException on the call to rowKeySet.removeAll().
Caused by: java.lang.NullPointerException
at org.apache.myfaces.trinidad.model.RowKeySetTreeImpl._selectAll(RowKeySetTreeImpl.java:459)
at org.apache.myfaces.trinidad.model.RowKeySetTreeImpl.removeAll(RowKeySetTreeImpl.java:146)
In my observation, this NPE happens when rowKeySet.size() returns 1 but rowKeySet.iterator() does not return any entries.
I suspect this is a bug on RowKeySetTreeImpl but not sure.
Help Need
=======
1. What is the reasonably right way to highlight the tree node for my problem?
2. If my trial is one way to do it, how can I get around the NPE? I cannot change ADF Rich Client library at this point.
Any help/suggestion/advise would be appreciated.
Thanks,
Jeongtae

I did this, to programmatically expand a tree node, you can try the same and set the row key to highlight.
private RowKeySet disclosedTreeRowKeySet = new RowKeySetImpl();
public void rowDisclosureListener(RowDisclosureEvent rowDisclosureEvent)
Iterator added = rowDisclosureEvent.getAddedSet().iterator();
if (added!=null)
while (added.hasNext())
Object rowKey = added.next();
//disclosedTreeRowKeySet.clear();
List path = (List)rowKey;
for( int i=0; i< path.size(); i++ )
List<Object> nodePath = new ArrayList<Object>();
for( int j=0; j<i; j++ )
nodePath.add( path.get( j ) );
disclosedTreeRowKeySet.add( nodePath );
disclosedTreeRowKeySet.add( rowKey );
System.out.println( "disclosed Keys...... " + disclosedTreeRowKeySet );
private void expandSelectedNode(RowKeySet addedObj) {
if (sourceTreeTable != null) {
Iterator added = (Iterator)addedObj.iterator();
if (added!=null)
while (added.hasNext())
Object rowKey = added.next();
List path = (List)rowKey;
for( int i=0; i< path.size(); i++ )
List<Object> nodePath = new ArrayList<Object>();
for( int j=0; j<i; j++ )
nodePath.add( path.get( j ) );
disclosedTreeRowKeySet.add( nodePath );
disclosedTreeRowKeySet.add( rowKey );
sourceTreeTable.setDisclosedRowKeys(disclosedTreeRowKeySet);
}

ADF Tree 10.1.3.1, not highlighting the selected node.

Hi,
I'm having a problem highlighting the selected node in the ADF CoreTree.
I use the treehandler and model as described in the link: http://technology.amis.nl/blog/2116/much-faster-adf-faces-tree-using-a-pojo-as-cache-based-on-read-only-view-object-showing-proper-leaf-nodes-again
I use this objects because my tree was showing leaf node with the image to collapse.
The tree now looks great, the only problem is that when i click on a node the focusRowKey is set accordingly(debugging the getter and setter) but is not show as the selected node.
The tree jspx code looks the follow:
               
                                 <af:tree value="#{ActosTreeHandler.treemodel}" var="node"
                                           focusRowKey="#{ActosTreeHandler.focusRowKey}"
                                           id="treeActos"
                                           varStatus="nodeStatus" binding="#{ActosTreeHandler.jsfTree}">
                                    <f:facet name="nodeStamp">
                                      <af:commandLink text="#{node.description}" partialTriggers="treeActos"
                                                      action="#{backing_documentos_detalhesDocumento.treeAction}">
                                        
                                        <af:setActionListener from="#{ActosTreeHandler.jsfTree.rowKey}"
                                                              to="#{ActosTreeHandler.focusRowKey}"/>
                                        <af:setActionListener from="#{node}"

I can not open my iPhoto Library in iPhoto or Aperture

Hi,
I am running iPhoto 9.4.3 and Aperture 3.4.5. I first had all my pictures in iPhoto, but swithced to Aperture a few years back, importing my iPhoto library to Aperture, and in the process I moved the library to an external harddrive.
Now I have rebooted my old iMac 2008 (OS X 10.8.5) and am attempting to start using iPhoto again, with the old library, but when I open iPhoto and try to choose which library to use, the only to librarys I can choose from are the new Aperture and iPhoto libraries that come with the program. I can see my old library on the external harddrive, but I can not highlight it. I have tried to open the library in Aperture also, but have the same problem there.
What am I doing wrong?

Ok, I had a closer look under diskutility... My EHD is showing on 2 lines... the top line says:
3TB WE My Book 1130... Format: Mac OS Extended
But the lower line says:
MY BOOK ...Format MS-DOS (FAT)
And when I go into Finder and click "Show info" on MY BOOK, it also says MS-DOS... so I must have done something wrong when I formatted the disk.... Can you help?

Fritz

If this is a production cluster, please call Sun support. If it was installed by them, you should have the SUNWscdtk package installed which should allow you to remove it using dcs_config (I think).
If it is just a cluster to play with (i.e. dev, test... basically unimportant if you mess it up), then you could 'hack' the ccr and remove the offending metaset. You'd need to boot the nodes in non-cluster mode (-x) and then go to the /etc/cluster/ccr directory and find all files with reference to the set. Some will just need a line removing (directory, IIRC), others will need to be removed completely (dcs_XXX). You will need to rechecksum these files using 'ccradm -i <file> -o' then boot into cluster mode again.
I would recommend backing up the /etc/cluster/ccr directory just in case it all goes pear shaped!
Remember, this is just for non-production clusters.

JTree Node highlight

Hi All
I am using Drag and Drop for JTree.
I want to highlight the target node(make the text bold) when drag is started and the cursor is over a target node. I tried retrieving the renderer. But could not succeed. Can anyone help me out...
Thanks in advance

Am I not clear?

How can i change the particular node color in Jtree?

I have constructed the tree.i dont know how to set the color for the particular node then how can i change the particular node icon depends on some conditions like if we will give the input whether it is available in jtree that node icon only changed.Anyone please help me as soon as possible.

Hope this helps.

"View Film Rolls" is not Highlighted.... how can I get to it? (iPhoto 6)

"View Film Rolls" is not Highlighted.... how can I get to it? (iPhoto 6)

Since you're using the term Rolls you must be running iPhoto 6 or earlier. For future problems be sure you post in the iPhoto 6 or forum.
For this problem the View File rolls will only Be sure you're clicked on the Library. That menu item is not available in an album or other item. If you have clicked the library icon first and it's still grayed out close iPhoto, delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your User/Library/Preferences folder and then try again.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

I can not start a remote server via Node Manager

There is a workaround to this problem. The issue seems to be
that when the node manager tries to start the managed server
it can not find java.exe in the system path. So please go to
Control Panel->System->...->Environment, and modify your PATH
system environment variable to include the java bin directory
in it.
Then try using the node manager again to start the managed
servers and you should have no problems.
We are aware of the issue and working on having a fix for it.

I am using WLS6.1 on WIN2000 boxes. And I am getting the same error on
the Admin
console when I try to start any of the two
managed servers.
<Sep 25,2001 1:39:12 PM EDT> <Info> <[email protected]:7002><WindowsProcessControl:
online successfully invoked on server 'server90', pid: 0> The interesting thing is that when I start managed server of its own,
it is started
successfully and you can Stop the managed
server from the Admin Console.
Really frusted, I hope I have configured everything correctly. Can somebody
help
me out ?
Thanks Rakesh

This message is simply a message from the Admin Server saying that it
has asked
NodeManager on the remote machine to start a certain server.
To see the logs for server startup then you can find these either on
the Admin
machine at WL_HOME/config/NodeManagerClientLogs/<ManagedServerName>/*.log
or on the remote machine at
WL_HOME/config/NodeManagerLogs/<ManagedServerName>/*.log
Cheers

I also would like to know the answer to the question below from Vincent.
I am getting
this message in the Admin console from either of my two managed servers
whenever
the console has successfully contacted the Node Manager in managed
server
host.
The Node Manager logs themselves also report "online successful". What
doesn't
seem to happen is WebLogic startup and I haven't found any error log
that explains
why.
I have set the Remote Startup parameters correctly [I think] for both
managed
servers so cannot see what further is required.
Any input appreciated.
Paul.

Hi everybody,
When I try to start a remote WLS 6.1 server from my computer, I receive
the message
below in my WLS administration console. The Node manager is runningon
the remote
machine and correctly configured, I hope!
What does this message mean ???
Thanks for your help

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.

Can not highlight a JTree node programmatically
