Sorting contents of a JTREE
Hi all..
I have a Jtree that needs to be sorted. How can it do it fast and efficiently as the size of the tree can be huge. I have the tree contents that has depth of max 4 or 5. Your help on this is greatly appreciated.
Thanks

Hi there ..
You can sort the tree by again recreating the tree nodes.
DefaultMutableTreeNode oldNodes = (DefaultMutableTreeNode)tree.getModel().getRoot();
DefaultMutableTreeNode newNodes = new DefaultMutableTreeNode(oldNodes.getUserObject());
void visitNodes(DefaultMutableTreeNode oldNodes,DefaultMutableTreeNode newNodes ){
Vector sorted = sort(oldNodes.children());
for (int i = 0; i < sorted.size(); i++)
DefaultMutableTreeNode chNode = new DefaultMutableTreeNode(sorted.get(i));
newNodes.add(chNode);
visitNodes((DefaultMutableTreeNode)sorted.get(i),chNode);
tree = new Tree(newNodes);hope this would help!
or you can also checkout the thread .. http://forum.java.sun.com/thread.jsp?forum=57&thread=189640

Sorting Content with PersonalizationAdvisor session bean
Hi,
I am working on content selection through the PersonalizationAdvisor session
bean not the jsp tags. Content selection is going on fine with my meta tags,
but whenever I try to sort on any of the fields of the WLCS_DOCUMENT it does
nothing. No errors are returned but the result set is not sorted.
I tried sorting on different fields but no hope. I suspect that the names I
am using my be incorrect.
For sorting on the MODIFIED_DATE column of the table I use the string
"modifiedDate ASC" in my ContentQueryAdviceRequest. Similarly
"createionDate", "author", "size"
I tied sorting by any of my meta tags but again it didn't work. I was
wondering if these are the correct names, and if they are any idea why the
sorting is not working.
I am using
Weblogic Server 5.1 with sp1
WLCS 2.0.1 with sp1
Any help is greatly appreciated.

Query and sort content from two lists using search API
Hi,
I have a custom web part which I would like to query two different lists and sort the results by Created Date. One is a list of news articles and the other contains blogs. So basically the result set will be an intermix of news and blog items sorted by date.
I would also like to do this by query through the search API. Does anybody have any sample code to do this?
thanks,
Sherazad.
SherazadHi Sherazad:
To use the JOIN operator in CAML, your lists must have a
defined relation(Lookup column). You can refer to sample code that I list as follow.
Create your query from one of your lists.
SPList Projects= SPContext.Current.Site.RootWeb.Lists["Projects"];
SPQuery query = new SPQuery();
To do the join, setquery.Joins
<Join Type="INNER" ListAlias="Contacts">
<Eq>
<FieldRef Name="ProjectManager" RefType="ID" /> ///
ProjectManager is a Lookup Column.
<FieldRef List="Contacts" Name="ID" />
</Eq>
</Join>
And query.ProjectedFields (To tell SharePoint how to project the lookup columns into the result)
<Field Name="Project Name" Type="Lookup" List="Projects" ShowField="Title">
/// My Project Name is a Display Name in Memory so you can give a name by yourself But ShowField must be Internal Name of the Column(Project Name)
You can add a lot of columns that you want to display.
Everything comes from memory.
To choose the fields to display set query.ViewFields
<FieldRef Name="Your Internal Name of Column Or
ProjectedFields - Field Name">
<FieldRef Name="Your Internal Name of Column Or
ProjectedFields - Field Name">
<FieldRef Name="Your Internal Name of Column Or
ProjectedFields - Field Name">
Then
SPListItemCollection result = ListA.GetItems(query); -
How can I sort content into a-z of album titles
Hi Everyone
Hope someone out there can help. I run two libraries on one pc at home, in library one I have the album icon view and I click on "Album" at the top and my albums are organised a to z by album title. However in library two, I cannot get itunes to do this, I have the same album icon view i click on "Album" on the top bar and it organises my albums a-z by artists name. I cannot see what I am doing wrong in library two. Any advise will be most welcome.

JTree - changed content, refresh
Hello,
I have a problem in my program I can`t solve...
basically I am using drop-down menu with different drives (c:, d:, etc.). Don`t ask me why I don`t use the JTree to display all the drives, I simply need to display each drive separately.
when I select the drive, JTree pops up with the content of the drive.
Problem comes in, when the JTree is already displayed and I go into my drop-down menu to select a different drive.... Everything seems to work fine in background.... The tree gets build up, I just somehow cannot update (or refresh) the screen....
did anyone experienced similar problem?

SORT statement is not working!
Hi frdz,
Below SORT statement is not working. Can any one explain me why this is happening.
SORT i_bseg ASCENDING BY belnr bukrs
DESCENDING kunnr.
I have table content as below.
BELNR BUKRS KUNNR
0016000000|CROP |
0016000000|CROP |0008910168
Before and after the sort content order is same.
I want to sort the content like below.
0016000000|CROP |0008910168
0016000000|CROP |
Is there any thing wrong with the sort statement???
i_bseg is defined as TYPE STANDARD TABLE OF
Sort criteria must not change i. e ascending by belnr and bukrs and descending by kunnr.
Thanks,
Vinod.hi vinod,
this is because on your statement, you are sorting BUKRS in descending order and KUNNR in ASCENDING order.
please take note that the sort order should come after the sorted field. if no order is given, the default which is ASCENDING will be used.
do your sorting like this
SORT i_bseg BY belnr bukrs kunnr DESCENDING.

Dynamically Updating Content Server Portlets
[urlHi, I am currently having difficulty dynamically updating content server portlets. I have a portlet of the following form:[/url]
ArticleName Author Title Date mystory author1 title1 04/05/01
story2 author2 title2 06/07/04
story author3 title3 01/02/03
So I have this table where each one of the line items is an article in the content server. So, for example the first line item is an article "mystory" by "author1", with title "title1" and date "04/05/01" additionally there is an article text field, but this isn't displayed unless I click on the article name.
I can set up the basics of this portlet, but when I try to add any real functionality I run into one of two problems.
First Problem: Passing Information
I cannot find a way to pass information between content portlets. For instance, if the user would like to "re-sort" this table based on "date", I would like to have the user click on the "date" column heading and then reload the page. To do so, I would have to pass the section name back to the page so that it could resort based on this data. I have not found anyway to effectively pass information to a content server portlet. I am building these pages through use of the presentation template framework (so I can have access to the content items) but that seems to change the way portlets are handled.
I got around this limitation with a regular portlet by creating an intermediary page which captures passed information and stores it to the session state. Once the information was in the session state, it is accessible to the portlet on the first page. However, this only works because remote portlets do not change their session id once loaded. Content Server portlets, on the other hand, change their session id after every reload of the browser or page change. I can send information from a content server portlet to an intermediary page, but I cannot send it back to the portlet because the session id has changed so I have no idea of knowing where to send the information. I can write it to a session state, but by the time I return to the portal page, the content server has changed its session id so it does not know where to look any longer.
I suppose it would be possible to create an application state variable and append it with some static token (if there is some static variable per portal session) but I would rather not have to deal with application variables if at all possible.
Second Problem: Dynamically Updating PCS Tags
Even if I were able to the pass information back to my content server portlet, I run into another issue. The easiest way to sort content server items is using the filter command in the pcs:foreach tag. So, if I wanted to sort by author name, I could do something like the following <pcs:foreach var="item" expr="filter(folderByName('content'), filtered.name == '"name")" or something like that (the syntax may be incorrect, I just wrote this off the top of my head). However, it appears that the way the presentation templates are compiled goes in the order of PCS tags THEN JSP. So I would have no way of dynamically changing the variable on which I sort. For example, if I clicked on "Date" above in my table, I would like to be able to dynamically change my code so that I sort on date, and not name. I cannot find a solution to this problem.
My workaround is to use the pcs tags to write out all the possible sortings to java array objects. This gives me access to the data on a JSP level and based on whatever the user will chose, I could then display that array. While this works, it is extremely ghetto and inefficient. Any help or suggestions would be fantastic.
Thanks a lot,
Jason GrauelYou can use just about any javascript you want in any Content Server presentation template including ones that are used for portlets.
However, you should be careful to name javascript functions and global variables uniquely so that they do not conflict with any other javascript on the page. To do this, you can append the item id to function and variable names, for example,
function doSomething<pcs:value expr="pcs_id"></pcs:value>() {
return true;

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. -
I've found a workaround and now his bookmarks are back in order by date added, but they are reversed, i.e., the last bookmark is at the top.
For those wanting the workaround (as I see this question was never properly answered) I opened "Show all Bookmarks", clicked on Bookmarks Menu, and View, Sort, and Sort by Added.
Then highlighted all his bookmarks, and copied.
Then created a new folder in the Bookmarks Menu, and pasted to that new folder.
I then created another folder and did it again as a backup, and deleted all his bookmarks in alphabetical order, then opened one of the folders I just made, copied the bookmarks and pasted them into the Bookmarks Menu.
(I made that extra folder just in case things didn't go as planned. He would have understandably freaked out had I deleted all his bookmarks without making another backup of them! After I saw that everything was cool, I deleted the extra folder.)
But still the order is reversed.
How do I reverse the reversed order?I am trying to think how your friends bookmarks came to be in a different order permanently and how you may be able to reverse that.
I note you have been copying bookmark folders. You have already discovered that the sort orders used to display may be varied and that second clicks toggle the order to be ascending or descending. If you copy a bookmark folder contents they retain the order that they were sorted on in the display when copied.
So if you have a folder. The bookmarks are in the order in which they were added. You may however display them in Alphabetical or reverse alphabetical order or reverse of the order added etc.
'''Try this I hope it will work'''
#Obviously back up the bookmarks first.
# In the bookmarks library re-sort the folder book marks menu.
# Create a new folder.
# Copy that the resorted bookmarks to the new folder.
# Delete the mis-sorted content and copy the new content over it -
Customizing JTree Nodes ImageIcons???
I have a JTree. Iam trying to customize the icons of it instead of the defaulticons available for leaf and branch nodes.I successfully set a new icon for leaf nodes by calling setLeafIcon.Also i can use setOpenIcon and setClosedIcon for the expanded and closed branches.
But in my application when my GUI is launched i actually set the JTree in its fully expansion form.
so there is no difference between setOpenICon and setClosedIcon as all of them are expanded.so how do i differentiate between the two and set different icons for both of them.
exmaple:Cricket club is my root node..I have for ex:ABC , BCD, and CDE club underneath that(branch nodes).Under each club i have player1,player2, player3. .etc..so i want to set 3 different icons,,one for cricket club, 2nd for ABC,BCD andCDE clubs and 3rd one for players.since my JTree is expanded the same icon is set for CricketClub(root Node) and ABC,BCD and CDE club(branch nodes)..How can iset different icons to these. can anyone help me on this..I am sort of new to JTree.So code snippet will be a welcome..
Thanks Much in advanceTo fully expand the tree, use the method scrollPathToVisible(TreePath path). The path is the path for your tree's last node. The DefaultMutableTreeNode class should have some methods to find the path for a particular node.
To set the icons for a particular node, depending on their opened or closed state, Make a subclass of TreeCellRenderer. If you look at the API for TreeCellRenderer, you will see that it will tell you if the current node is expanded, selected, leaf, hasfocus, etc...
If you want to set an open icon for an expanded node, just check if it is expanded. Cast the Object value to a DefaultMutableTreeNode and set the Icon for it, unless you have your own class for your nodes. Lastly, set your renderer for your JTree with setCellRenderer(TreeCellRenderer ren). I hope this helps. -
How to replace original JTree node with + and - sign or icon??
Dear friends:
I have following code for JTree:
import java.awt.BorderLayout;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTree;
public class TreeSample {
public static void main(String args[]) {
JFrame f = new JFrame("JTree Sample");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Container content = f.getContentPane();
JTree tree = new JTree();
JScrollPane scrollPane = new JScrollPane(tree);
content.add(scrollPane, BorderLayout.CENTER);
f.setSize(300, 200);
f.setVisible(true);
}Here, when I click any node to explore its children, right handle pointer become down handle Pointer, but if I hope to change this right handle pointer to + sign or icon; and to change this down handle pointer to - sign or icon; how to do it, ??
Is there any simplest way instead of using ImageIcon ????
Thanks

Hello, everyone.
Guys, maybe any of you encountered with that problem in Thunar... especially if you use cyrillic letters in file or folder names.
I have the latest version of Thunar (1.4.0) installed, and it turns out it incorrectly sorts contents of folders.
I can not even understand the way Thunar sorts contents of any folder.
Here is the contents of one folder "sorted" by name (ascending).
Looking from top to bottom I see file names starting with...
cyrillic upper letters
digits
cyrillic lower letters
again digits
again cyrillic lower letters
english lower letters
and again cyrillic lower letters
Concrete example of another folder "sorted" by name:
голубь.txt
иволга.txt
аист.txt
орёл.txt
сова.txt
Absoluletly wrong order. The file with name that starts with 'A' is in the middle.
Cyrillic alpabet is:
Аа Бб Вв Гг Дд Ее Ёё Жж Зз Ии Йй Кк Лл Мм Нн Оо Пп Рр Сс Тт Уу Фф Хх Цц Чч Шш Щщ ЬЬ Ыы ЪЪ Ээ Юю Яя
Meanwhile
ls -1
gives right order
аист.txt
голубь.txt
иволга.txt
орёл.txt
сова.txt
PCManFM and other filemanagers give right sort order.
So, Thunar DOES NOT sort with 'ls'. Also, sort order of Thunar CAN NOT be changed using LC_COLLATE.
Thunar uses its own "mega-wise" algorithm.
P.S.
By the way, before version 1.4.0, everything was OK in Thunar. So one day their devs decided to make some "improvements".

This is open source, bro. You can't make anybody do anything, but you might encourage some admin to ban you if you willfully break rules.

JTree: Problems updating the nodes size
Hi,
I'm trying to update the content of a JTree and I wonder how it
really works, since the paint() method doesn't seem to call the
renderer.
My situation: Imagine a JPanel splited in two by a JSplitPane. In
the left is the tree. Each node in the tree shows two panels, one
aligned to the left, and another to the right. I need that the panel
containing the two use all the available space in the left part of the
Split panel.
My solution: I pass the left JPanel to the tree renderer, so that
it can get the width from it (inside the
getTreeCellRendererComponent()) to build the return JPanel with the
correct size. My logic is that since each time you move the JSplitPane
the JTree paint() method is invoked the renderer can return the
correct JPanel with the correct size that will be painted then in the

My problem: Doens't work. When I render the tree, the renderer is
invoked, but it doesn't change its size (I can change the color based on the width, but not the node size). Only when I collapse & expand a node, it correctly takes into account the .setPreferredSize() and returns the JPanel with the correct size.
The only way I found to update the tree involves to catch the
JSplitPane event and call updateUI() in the tree, something that, I
think, it's certainly not the correct way to do it.
Any explanation of why this doesn't work would be really great. Any
pointer to a web resource explaining in deep how Swing components work (specially the JTree) would be a godsend.
Thanks,
- JuanchoMy situation: Imagine a JPanel splited in two by a JSplitPane. Got it.
In the left is the tree. In the left side of the JSplitPane is a JTree.
Each node in the tree shows two panels,Maybe... on the right side of the JSplitPane are two Panels in which the data depends on which node is selected in the JTree???
Maybe... you have a custom TreeCellRenderer which displays a pair of panels in place of the standard JLabel???
one aligned to the left, and another to the right. To the left of what??? To the right of what???
I need that the panel containing the two use all the available
space in the left part of the Split panel.Panel containing the two what??? I thought the left part of the SplitPanel contained a JTree??? -
Hi!
I am using a TreeModel to manage the content of a JTree.
I provide buttons to add/remove items in the tree. The content is correctly modified (when I do some System.out.println(...)), but I don't see the new items on my displayed tree.
I tried to use
JTree.revalidate();
JTree.repaint();
And the same on the panel containing the JTree, nothing works!
What should I do?
Thanks a lot
ChoubHi,
you can try with this sample code:
* <p>Adds a new objects in the JTree. </p>
* @param parent - the DefaultMutableTreeNode parent
* @param child - the object to add
* @param shouldBeVisible - if it is true, all the path components in path
* are expanded and scrolls so that the
* node identified by the path is displayed.
* @return a DefaultMutableTreeNode object
* @see javax.swing.tree.DefaultMutableTreeNode
public DefaultMutableTreeNode addObject( DefaultMutableTreeNode parent,
Object child,
boolean shouldBeVisible) {
DefaultMutableTreeNode childNode = null;
switch ( this.levelSelected ) {
case 0: childNode = new DefaultMutableTreeNode(
new IconData( rm.getIcon("db/Computer.gif"), child ) );
break;
case 1: childNode = new DefaultMutableTreeNode(
new IconData( rm.getIcon("db/BCard.gif"), child ) );
break;
case 2: childNode = new DefaultMutableTreeNode(
new IconData( rm.getIcon("db/Thread.gif"), child ) );
break;
if ( null == childNode )
return null;
if ( null == parent ) {
parent = root;
model.insertNodeInto( childNode, parent, parent.getChildCount() );
model.reload();
if ( shouldBeVisible ) {
logicTree.scrollPathToVisible( new TreePath( childNode.getPath() ) );
return childNode;
Regards.
