Tree node color

Last resort here. Calling all hands on deck. I want to be
able to search my tree for anything that starts with AOL and expand
the tree and color/bold/ anything to the node that meets the
requirements. I have all of it working except for the coloring
part. This(of course) does not work. But maybe something along this
thought process:
[email protected] = "red";
myXML.node.@label Gets the tree nodes just fine, I just don't
know how to color the text. Any help or push, maybe a kick in the
right direction would be appreciated.

Anything?

How to highlight Tree node with a diff color

I have created tree node and want to highlight Selected node with a different background color. Any Ideas how can we achieve that? -R

It's an item on page 4 of the application that the blog example is taken from. The tree query:
SELECT EMPLOYEE_ID AS ID
     , MANAGER_ID AS PID
     , CASE
         WHEN EMPLOYEE_ID = :P4_EMPLOYEE_ID THEN
             '<span style="color:white;background-color:blue;">'||
             LAST_NAME||
             '</span>'
         ELSE
             LAST_NAME
       END AS NAME
     , 'f?p=&APP_ID.:4:'||:SESSION||'::NO::P4_EMPLOYEE_ID:'||EMPLOYEE_ID AS LINK
     , NULL        AS A1
     , NULL        AS A2
FROM #OWNER#.EMPLOYEESgenerates leaf nodes that link to page 4, setting the value of P4_EMPLOYEE_ID. When page 4 is rendered, P4_EMPLOYEE_ID contains the ID of the clicked node, the page displays details of the employee with this ID, and the case expression in the tree query causes the corresponding display value to be highlighted.
See the sections Managing Session State Values and Using f?p Syntax to Link Pages in the documentation to understand how to set session state values using URLs.

How to resize a custom tree node like you would a JFrame window?

Hello,
I am trying to resize a custom tree node like you would a JFrame window.
As with a JFrame, when your mouse crosses the Border, the cursor should change and you are able to drag the edge to resize the node.
However, I am faced with a problem. Border cannot detect this and I dont want to use a mouse motion listener (with a large number of nodes, I fear it will be inefficient, calculating every node's position constantly).

the node on the tree is only painted on using the
renderer to do the painting work. A mouse listener
has to be added to the tree, and when moved over an
area, you have to determine if you are over the
border and which direction to update the cursor and
to know which way to resize when dragged. One of the
BasicRootPaneUI has some code that can help determine
that.Thanks for replying. What is your opinion on this alternative idea that I just had?
I am wondering if it might be easier to have a toggle button in the node that you click when you want to resize the node. Then a mouse-down and dragging the mouse will resize the node. Mouse-up will reset the toggle button, and so will mouse down in an invalid area.

JTree - Fetch URL from a tree node.

Now I have created one JTree and one JEditorPane.
Basically I am creating a help file. (a chm file in windows).
So I need to handle mouse click event on each node on JTree.
I have used such format to add a hyperlink.
sample code:---------------------------------------------------------------------------------------------------------------------------
javax.swing.tree.DefaultMutableTreeNode treeNode1 = new javax.swing.tree.DefaultMutableTreeNode("JTree");
javax.swing.tree.DefaultMutableTreeNode treeNode2 = new javax.swing.tree.DefaultMutableTreeNode("colors");
javax.swing.tree.DefaultMutableTreeNode treeNode3 = new javax.swing.tree.DefaultMutableTreeNode("blue");
treeNode2.add(treeNode3);
treeNode3 = new javax.swing.tree.DefaultMutableTreeNode("violet");
treeNode2.add(treeNode3);
treeNode3 = new javax.swing.tree.DefaultMutableTreeNode("red");
treeNode2.add(treeNode3);
treeNode3 = new javax.swing.tree.DefaultMutableTreeNode("yellow");
treeNode2.add(treeNode3);
treeNode1.add(treeNode2);
treeNode2 = new javax.swing.tree.DefaultMutableTreeNode("s");
treeNode3 = new javax.swing.tree.DefaultMutableTreeNode("<html><a href='C:\\Program Files\\Java\\jdk1.6\\README.html'>Read Me</a></html>");
treeNode2.add(treeNode3);
jTree1.setModel(new javax.swing.tree.DefaultTreeModel(treeNode1));
jTree1.addMouseListener(new java.awt.event.MouseAdapter() {
public void mousePressed(java.awt.event.MouseEvent evt) {
TreeListener(evt);
private void TreeListener(java.awt.event.MouseEvent evt) {
int selRow= jTree1.getRowForLocation(evt.getX(), evt.getY());
TreePath tp = jTree1.getPathForLocation(evt.getX(), evt.getY());
if(selRow!=-1) {
if(evt.getClickCount()==1) {
jTree1.setSelectionPath(tp);
Now there is a hyperlink created for that node "Read Me".
My Question is ..........
How do I fetch this stored URL in each node for setting it to my JEditorPane....???

ok, it seems to be working now. I just return the JInternalFrame in the getTreeCellRendererComponent() method.

JTree Node Color, to distinguish between different activities

Hi,
Situation:          Dynamic JTree (Tree is constructed from as a result of Database). User has the option to either Enable / Disable node and can repeat the activities but restricted only one activity per node, the node is to be highlighted; to restrict the user from further activities.
Problem:          Am a newbie to swing, after searching the forum for the same, i found few good solutions which are specific to color change of specific selected node, in a temporary context.
     But we need the node color change within a same level; to distinguish either the node is either enabled / disabled.
Your help is appreciated,

1. Is the approach above a good approach, how to load children 'lazilly'?Sounds pretty reasonable to me.
2. I also use custom renderer to display different icons for every "tree" level. When I initially expand the 4th level, everything works fine !!! Then I collapse the 4th level and expand it again and here my problem starts: my 4th level icon is set to 'root level icon' instead of '4th level' icon. This does not happen, if computerNode.removeAllChildren(); method is removed from listening above
Any idea, what am i doing wrong?Ummmm... Load the model the first time (only) the node is expanded... Putz!
And I suggest you listen deeply to Mr Jacobs... He really does know what he's talking about ;-)
... and not this time, but in future: Swing questions are best asked in [THE Swing Forum|http://forums.sun.com/forum.jspa?forumID=57].

Hi,
These the code you want to put in your MOVE_UP and MOVE_DOWN action:
if (action.equals(MOVE_UP_ACTION))
DefaultMutableTreeNode nextNodeUp = (DefaultMutableTreeNode) parentNode.getChildAt(treeSelectIndex - 1);
DefaultTreeModel jTreeModel = (DefaultTreeModel) tree.getModel();
jTreeModel.insertNodeInto (treeSelectNode, parentNode, treeSelectIndex-1);
jTreeModel.insertNodeInto (nextNodeUp, parentNode, treeSelectIndex);
jTreeModel.nodeChanged(parentNode);
jTreeModel.reload(parentNode);
TreePath treePath = new TreePath(jTreeModel.getPathToRoot(treeSelectNode));
tree.setSelectionPath(treePath);
if (action.equals(MOVE_DOWN_ACTION))
DefaultMutableTreeNode nextNodeDown = (DefaultMutableTreeNode) parentNode.getChildAt(treeSelectIndex + 1);
DefaultTreeModel jTreeModel = (DefaultTreeModel) tree.getModel();
jTreeModel.insertNodeInto (treeSelectNode, parentNode, treeSelectIndex+1);
jTreeModel.insertNodeInto (nextNodeDown, parentNode, treeSelectIndex);
jTreeModel.nodeChanged(parentNode);
jTreeModel.reload(parentNode);
TreePath treePath = new TreePath(jTreeModel.getPathToRoot(treeSelectNode));
tree.setSelectionPath(treePath);
Hope this help,
Diego.

How to display the tree nodes distinctivly.

Hay all,
Frnds , i am facing a problem. I have created a tree whose each node consisted of a checkbox and a label. For that i have used DefaultMutableTreeNodes for tree nodes and a TreeCellRenderer. Is there any method or way to display some nodes distinctively(may be in different color or something else). Plz tell me soon its very urgent.

Hi Jürgen,
See http://help.sap.com/saphelp_nw04/helpdata/en/44/6aaf92f5a23672e10000000a114a6b/frameset.htm
Only Worksets and Roles are not described, anyhow, doing a bit research via decompiling or just by searching on SDN will bring you the needed extra info; just as an example for roles access: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/6112ecb7-0a01-0010-ef90-941c70c9e401

Determine if mouse is over tree node

hi.
I recently added some code from this forum on
highlighting a node when the mouse is over it.
I am taking this futher and setting a Border around the nodehowever it draws a border around every node.
I want to only draw the border when the mouse is over the node.
the example i got does this to set the foreground
((JLabel)result).setForeground(Color.red);
i do this to set the border
((JLabel)result).setBorder
(BorderFactory.createLineBorder(Color.black));
i ve tried getting the positions of both the mouse and the jlabel but am having trouble determining if the position of the mouse is within the position of the node in the tree.
Ive used methods like the contains method but it doesnt work for me . can anyone give me a hint as to how to see if the points of the mouse are on the Jlabel?

This is very close to your solution. Last month, I implement ToolTip Text on every Tree Node so when Mouse goes on to the Node, It shows the Tool Tip Text. Have a look at this code and try to change it accordingly.
This code is in the Constructor in your class.
tree.setCellRenderer(new IDETreeCellRenderer());
tree.setToolTipText("");Class: IDETreeCellRenderer - Cell Renderer for the Tree

public class IDETreeCellRenderer
    extends DefaultTreeCellRenderer {
   DefaultTreeCellRenderer label;
    * Override TreeCellRendererComponent, used for changing Tree Node for comments.
    * @param tree Tree to be used

    * @param selected true, if selected

    * @return Component, Tree
   public Component getTreeCellRendererComponent(JTree tree, Object value, boolean selected, boolean expanded,
                                  boolean leaf, int row, boolean hasFocus) {
      try {
      label = (DefaultTreeCellRenderer)super.getTreeCellRendererComponent(tree, value, selected, expanded, leaf, row,
                                                  hasFocus);
      label.setToolTipText(dataObject.getToolTipText());
// Instead of setToolTipText(), try setBackgroundColor() or setBorder()
     return label;
      } catch (Exception ex) {
      // NullPointerException, usually comes at the start of the Application
      // when the Tree is empty.
      return this;
}Hope this Helps

Af:tree - how do I highlight the selected tree node?

af:tree
I checked the generated CSS file. I found that when a tree node is selected, the related CSS attribute is:
.xj:link{
font-family:Arial,Helvetica,Geneva,sans-serif;
font-size:10pt;
font-weight:normal;
color:#663300
I created a customized CSS attribute, but then all of the links have the customized CSS attributes.
How do I just highlight the selected tree node link?
Thanks,
--Todd

try doing the onclick javascript method
you have to place it on the node element and id must be made dynamic
for this use 'this.id'
by which the current id of the node is passed
and by capturing the id name in a var
use the same for invoking its selected property and make it true
like this
var currentid = this.id;
this.form.currentid.selected = true;

Urgent please respond... JTree Speceific Node Coloring

hi
i am facing a problem.I want to create root node with different color anf font and its child node with different color and font.When I change the color of my tree the whole tree nodes are given the same color.Is there any way in which i can color different nodes in the tree with different colors and font?

Use TreeCellRenderer
"javax.swing.tree.TreeCellRenderer"

Tree Nodes has White Outline/Border

Hi,
I'm using an ADF tree located inside a panelGroupLayout.
The panelGroupLayout has the background color "light blue".
At runtime each tree node is displayed with a surrounding white outline and that can only appear when you have a background color different than white (in my case the panelGroupLayout is "light blue").
Does anybody knows how to remove that outline? or to change its color?
Thanks,
Alain.

Here are the skin seletors
tr:tree Component
Icon Selectors
Name      Description
af|tree::expanded-icon      This icon is displayed before the expanded tree node.
af|tree::collapsed-icon      This icon is displayed before the collapsed tree node.
af|tree::no-children-icon      This icon is displayed instead of the expanded/collapsed icon, when the node has no children
af|tree::line-icon      This icon is used as a vertical line between the nodes.
af|tree::line-middle-icon      This icon is used as the horizontal line in the background of the expand/collapse icon of the node, in the case the node is not the last sibling of its parent node.
af|tree::line-last-icon      This icon is used as the horizontal line in the background of the expand/collapse icon of the node, in the case the node is the last sibling of its parent node.
af|tree::node-icon      This icon selector is used in the case the Node class has a getNodeType() method that returns the node type as string. The nodetype gets added to this selector, separated by a ':'. If the node is a container (has children) the following suffixes get added depending on the expanded/collapsed state: '-expanded' / '-collapsed'. e.g. "af|tree::node-icon:container-collapsed", "af|tree::node-icon:container-expanded", "af|tree::node-icon:noncontainer".

Change the Node Color

how do i change the Node color in the JTree

What do you mean it doesn't help you? PhHein told you you need to use TreeCellRenderer and gave you a link to a tutorial, what more do you want? You need to create a class that implements TreeCellRenderer like:
private static class CellRenderer implements TreeCellRendererAnd implement this method:
public Component getTreeCellRendererComponent(JTree tree, Object value, boolean selected,
boolean expanded, boolean leaf, int row, boolean hasFocus)If you want to be spoon fed, you need to pay for a tutor.

Apex Tree Node Search

Hi guys,
I want to search a tree node by using a textbox and a button item. I have implemented all required items and regions into my page. I think that, i can do this by using dynamic action. So I wrote a small script (jquery) to use in dynamic action in button click event. It gets the value of the textbox item and tries to use this value in tree's search method. By the way I specified a static ID for my tree region. (As you can see it is TREEID). But it doesn't work. Maybe usage of the method is different.
So ,
1 : The method usage is right?
2 : Do you have any other idea about how can i do this search stuff.
$("#TREEID").tree("search", document.getElementById("P300_SEARCH_TEXT").value);
Database : Oracle11g
Apex version : 4.1
Thanks

Mimi gave a very good start though. I have not worked with a tree before, but those tips guided me to the documentation, and i was able to take it from there. I can't see how the documentation would be lacking for you though, i find it to be clear. However, if you don't have some experience with javascript/jquery, this will not be straightforward.
I made a new tree page, based this on EMP.
When you want to do a search, you will first need the tree object, since the search function is a function of that object. I opened Firebug and ran this in my console:
jQuery.tree.focused()This is in the docs. "This functions returns the currently focused tree instance."
If you would have more trees, you could always use
jQuery.tree.reference(needle)This functions returns a specific tree instance by an ID or contained node.
Arguments:
mixed needle
This can be either the instance ID (the ID of the container node), an ID of any contained DOM element,
an actual DOM element contained within the tree, or a jQuery extended DOM node container within the tree.>
Now you have your tree object. Let's do a search. There are 2 employees with 'LL' in their names. I want to grab those.
$.tree.focused().search("LL")This'll do "nothing". Why? Take a look at the documentation:
Searches all nodes whose titles match a given string. If async is used a request is made to the server, the response should contain the comma-separated IDs of nodes that need to be opened so that all nodes that match the search string are visible.
The search string is provided in the request. The function triggers the onsearch callback, with the nodes found as a parameter.
Arguments:
string needle
The search string.
string compare_function
Optional argument. The jQuery function to be used for comparing titles to the string - defaults to "contains".>
What is of importance here is this: The function triggers the onsearch callback
+(oh, and please note that the search is looking for a match in the TITLE of the nodes!)+
So, taking a look at onsearch:
callback.onsearch Triggered after a search is performed and results are ready.
Receives two parameters - a jQuery collection of nodes matching the search and a reference to the tree instance.
*Default is: function(NODES, TREE_OBJ) { NODES.addClass("search");* }
>
So the default action of a search is something very simple: it assigns a class to the nodes which match the search criteria.
If you would want more complex things to happen, you can simply provide another function to the tree object for the onsearch callback, and that is what Mimi meant with changing it. But you don't have to if the class-adding is sufficient.
So, running from my firebug console:
$(".search").css({"background-color":"red"})Grab all elements with class 'search', and give them a red background color. My nodes are now red for "ALLEN" and "MILLER".
It also helps to use something like firebug, have knowledge of jquery, DOM and being able to inspect it, and read docs. I did not do anything special except applying some knowledge and taking my lead from those docs. Of course, Mimi mentioned this aswell, but the docs are at *\apex_images\libraries\jquery-jstree\0.9.9a2\documentation.html*
Hope that helps you forward.
