UIX Tree Component

I have an issue with using tree component for our application. We need to provide expand/collapse facility for tree component (using default (+) and (-) icons). Does ADF_UIX support s for this situation. Please provide me any guideline....

ADF UIX Tree Component

Can i create event for expand all / collapse all ADF UIX Tree ?
If i can ,could you please advise how i should to do ?
Thanks

Hi Daniel,
Are there any one can tell me when the new ADF UIX
demo based on uix 2.2 be released?I'm not sure when any sample applications will be released, but there is an ADF UIX tutorial available here:
http://otn.oracle.com/products/jdev/collateral/tutorials/9050/adfuix_tut.html
I want to know if we can get databind uix tree
component (or other ui components) from ADF data
action control which return dataobject and something
else.I'm not sure about the tree component - I'll try to find out whether that is/will be supported. Once your data controls are available in the Data Control Palette, you can bind them to components in your UIX page by:
1. Selecting the data control that you want to bind.
2. Selecting a component type from the "Drop As" choice.
3. Dragging the data control onto the UIX page.
This process is illustrated in the tutorial above.

Skinning UIX tree component

Are there any possibilities to skin tree component somehow?

Changing the avatar size doesn't seem to have any affect. Do
you know what the Avatar is for? It appears to be a bounding box of
some sort, but resizing it doesn't seem to change anything.
Actually, I notice that if I open the avatar, it says it is
22x80, although the scaled version in the Slider is 3x80. It seems
to be some sort of shared component. If I resize the contents of
the avatar, all my buttons change, but the sliders don't actually
change. Sadly, it seems like "3" is a hard coded value somewhere in
the source. Blah.

A question about the Tree Component

I have try to use the tree component i a flash page, and
it´s going allright until I´ll want to link the content
to a page... WHY??
I have tried a lot of different codes here are those I tried:
<tree>
<folder label="Mine own">
<link label="My page" url="
http://www.mickesei.se" />
</folder>
</tree>
Nr2:
<tree>
<folder label="Mine own">

http://www.mickesei.se" />
</folder>
</tree>
But nothing seems to work, when I go mouse over it still a
arrow should it?
HELP ME PLEASE!!! Micke

Thanx Jeanne,
You brought me on a idea with the UIX Developer's Guide and EXPANDABLE_EXPANDED value.
I couldn't figure out how the expand property was filled, because it wasn't done in the ADF BC ViewObject. We have a Utility class that creates a DataObject from the ViewObject Data and here the expand property was set.
Now it was easy to build a ExpandAll option. It is possible to access the HttpServletRequest object were the DataObject is created. By setting a attribute in the request I could react on that and give the expand property indeed the value EXPANDABLE_EXPANDED.

UIX Tree: "Expand All" Functionality

Hello,
I have a question about the Tree in UIX. We are using the Tree component in a UIX Page (JDeveloper 10.1.2). With the tree we also make use of the ClientStateTreeDataProxy class.
It is possible to expand and collapse the tree, but I want to have 1 button to be able to expand all nodes on the first level of the tree or if this isn't possible to expand all the nodes.
I have try to simulate this using struts actions, but I'm unable to simulate the state request-parameter. I also try to look if something is possible with the ClientStateTreeDataProxy class. Which possibilities are there to manipulate the tree component?
Thanks, Dennis

UIX:Tree Control

Hi,
Has anybody used or know to use the UIX:Tree control part of the UIX Simple JSP Components? If so can you please tell me if this helps creating a DHTML Tree component?
Thanks

Hello there,
You should check out the "Data Trees" chapter of the UIX Developer's Guide. It goes into a lengthy description of the tree component and how to code it in UIX. The tree component does not use DHTML, but rather rerenders based on its state (what is expanded and collapsed).

Custom icon per entry in the AS2 Tree Component (using CS3)

I have a tree component that loads its data from an XML file and I wonder if I can customize every entry to have its own icon by adding an icon attribute to every entry in the XML and giving the tree an action to read that icon (which would exist in the library of the Flash file). My goal is to reproduce a tree within an application that my company is developing (it's for a training tool related to that application).
My XML says something like <node label = 'Label' heading = 'LABEL' desc = 'Description' icon = 'icon1' />
My label is what the tree displays, the heading is what the information dialog in the training tool displays as a title bar, the desc is what the training tool displays within the body of the text for the function description and the icon is what I want to be a reference to the graphic in the library to place as an icon in front of the item rather than use setStyle with the properties for disclosure, leaf, and folder icons.
Is that possible? I haven't found a solution for it yet.

I've never used the Tree component, so I'm just guessing here....
There is a slight delay before the xml file loads and your tree has its data provider.
Perhaps during that time there is no node at mTree.getTreeNodeAt(0) to open? Try adding this just before the last line of your code:
trace("the node is: "+mTree.getTreeNodeAt(0));
What do you get?
You might need to move that code inside the xml's load event handler.
Another thing is that the Flash components tend to work on an invalidate-then-wait-one-frame-to-redraw kind of model. So it is possible you will need to wait one frame after the xml has loaded and then tell it to open that node.
The doLater method might help with that.
var home:MovieClip=this;
var xmlTreeData:XML = new XML();
xmlTreeData.onLoad = function() {
mTree.dataProvider = this.firstChild;
mTree.doLater(home,"delay");
xmlTreeData.ignoreWhite = true;
xmlTreeData.load("xml/treeValues1.xml");
mTree.setStyle("fontSize","11");
mTree.setStyle("selectionColor","0xE0E0E0");
mTree.setStyle("useRollOver",false);
function delay(){

Label display issue in Tree component when it is having vertical scrollbar

I am using tree component as dropdown factory for combo box. When i open dropdown, it doesn't have vertical scrollbar and all the root nodes are getting displayed correctly(in closed mode). Now if i try to open any node, i am getting vertical scrollbar as the child nodes are more. Now the problem is if scroll down, some of the nodes(labels) are not getting displayed but i am able to see the icon. If i keep on scrolling bottom to top and top to bottom, some of the nodes are showing labels and some are not(It is inconsistant).
I have not used any custom item renderer for tree control. I used my custom dataDescriptor which i have implemented from ITreeDataDescriptor. Also I tried extending DefalutDataDescriptor, but no luck.

Does it work if the tree is not in a combobox?

Uix:Tree - How to populate in jsp ?

Hello all,
I'm having trouble to know how to populate an <uix:tree> in a JSP page. I see the UIX Developer's guide and the SimpleTreeData example and the documentation about uix:jsp is very poor. The data that will be posted in the <uix:tree> was provided by IFS. Then, I populate a DataObjectList with the files name. The point is that I don't know how to make a link between this DataObjectList, populated in a class(*.JAVA) file and the <uix:tree>(*.JSP) file. I wanna know how to use only <uix:jsp> and don't use *.UIX files, only *.JSP and *.JAVA files, ok ?
Here are some code part :
This is the JSP file
<%@ taglib uri="http://xmlns.oracle.com/uix/ui" prefix="uix" %>
<%@ page import="Hierarquia" %>
<%@ page import="oracle.cabo.ui.data.DataObjectList" %>
<%@ page contentType="text/html;charset=windows-1252"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>
Ifs - PublicaÃ§Ã£o de Documentos
</title>
</head>
<uix:document>
<uix:styleSheet />
<body>
<uix:body>
<uix:pageLayout>
<uix:contents>
<uix:form name="teste">
<uix:contents>
<%
DataObjectList dados = null;
Hierarquia x = new Hierarquia();
x.conecta();
x.populateTree();
dados = x.getResultSet();
%>
<uix:formattedText text="Teste" />
<uix:tree id="arvore_teste" nodesBinding="????" formName="teste">
</uix:tree>
</uix:contents>
</uix:form>
</uix:contents>
</uix:pageLayout>
</uix:body>
</body>
</uix:document>
</html>
Thanks folks !
Carlos

Carlos -
I believe that the best way to do this is to use scriptable variables, eg:
<uix:tree id="arvore_teste">
    <%
      // Assuming "dados" contains your tree data
      arvore_teste.setNodes(dados);
    %>
</uix:tree>See the "Scriptable Variables" section in the "UIX JSP Tag Libraries" chapter of the UIX Developer's Guide for more info...

Layout issue with af:tree component

I am using af:tree component but I am finding layout issue with it. I have a requirement where in I need the tree to stretch to the available space but a horizontal and a vertical scrollbar comes up automatically. Is there a way to handle this issue?

User, without your jdev version it's hard to help.
Have you embedded the tree component in a stretch layout?

[F8] Tree Component: How can I hide/remove the scrollbar and border?

I'm using the Tree Component in my Flash 8 Pro - Project. I'm
trying to customize the look of the Tree component in two ways:
1. Is there any way to remove the scrollbar from the Tree
Component?
2. Can I also remove the Border from the Tree Component?
I checked the Component Inspector and couldn't find any
options for the scrollbar nor the border.
Does anyone know how to do this or could you point me in the
right direction?
Thanks

You can use the Status-4-Evar extension to replace some functionality that was lost withthe removal of the Status bar in Firefox 4.
Open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout" after you have installed the Status-4-Evar extension and drag the items (Status Text, Progress Meter, Download Status) upon the Add-ons Bar (View > Toolbars > [X] Add-on Bar)

Tree Component Icons

I'm using the tree component for a little Windows Parody I'm making. In my .fla, There's a tree component that loads an external XML file. I can't figure out how to add custom icons to my component, though.
I know it's possible to set the icons for just the default folder and file icons, but since it's a Windows Parody, there'll be different icons for different file types, folder types, etc.
In other words, I'd like to have a different icon for every item in my Tree component.
How can I do this?
Here are the contents of my XML file:
<node>
    <node label="Desktop">
</node>
    <node label="Documents">
<node label="Pictures" isBranch="true" />
<node label="Movies" isBranch="true" />
<node label="Games" isBranch="true" />
<node label="Video" isBranch="true" />
</node>
    <node label="Computer">
<node label="Local Disk (C:)" isBranch="true" />
<node label="Local Disk (D:)" isBranch="true" />
<node label="DVD-RAM Drive (E:)" isBranch="true" />
<node label="DVD/CD-RW Drive (F:)" isBranch="true" />
</node>
<node label="Readme.txt" isBranch="true" />
</node>
And the code on the first frame of my .fla file. The Tree's name is "fileTree", and the XML file is "doors_explorerXML.xml".
//Tree
var fileDP:XML = new XML();
fileDP.ignoreWhite = true;
fileDP.load("doors_explorerXML.xml");
fileDP.onLoad = function() {
    fileTree.dataProvider = this.firstChild;
Also, I don't need to have an XML file loaded. If there's an easy way that does it all within Flash, please tell me. I just need to be able to handle events from the Tree.

Im having the same issue. I dont know how to change the tree icons separately with the xml. Is there anyone who knows how to do it?
This is what I got so far. However, i can only get my first branch to show custom icons. I tried ALOT, but i guess I´m doing something completely wrong.
Here is the code for my tree so far:
my_xml = new XML();
my_xml.ignoreWhite = true;
my_xml.load("tree.xml");
my_xml.onLoad = function(){
myTree.dataProvider = this.firstChild;
var folders = my_xml.firstChild.firstChild;
var docs = folders.childNodes;
for (var i=0; i < docs.length; i++){
currDoc = docs[i];
trace(docs[i]);
var docIcon = currDoc.attributes.pic;
switch(docIcon){
case "pdf":
myTree.setIcon(currDoc, "pdfIcon");
break;
case "word":
myTree.setIcon(currDoc, "wordIcon");
break;
case "excel":
myTree.setIcon(currDoc, "excelIcon");
break;
case "ie":
myTree.setIcon(currDoc, "ieIcon");
break;
}//switch
} //for
};//onLoad
And here is the XML I used:
<node label="» Dokument typer">
<node label="» links - document">
<node label="test.url" url="http://www." pic="ie" info="test text" />
<node label="test.doc" url="test.doc" pic="word" info="test text" />
<node label="test.excel" url="test.xls" pic="excel" info="test text" />
<node label="test.pdf" url="test.pdf" pic="pdf" info="test text." />
</node>
<node label="» Links - document">
<node label="test URL" url="http://www." pic="ie" info="test text." />
<node label="test URL" url="http://www." pic="ie" info="test text." />
</node>
</node>

Questions about AS2 Tree Component (Flash CS3)

I have Flash application with a Tree component on the Stage. I'm using an XML file to create the structure of the Tree component.
Each entry on my XML has the attributes id, label, heading, desc, and icon.
My problem is that I can't seem to be able to set the Tree to default with the first node open.
My code is:
var xmlTreeData:XML = new XML();
xmlTreeData.onLoad = function() {
mTree.dataProvider = this.firstChild;
xmlTreeData.ignoreWhite = true;
xmlTreeData.load("xml/treeValues1.xml");
mTree.setStyle("fontSize","11");
mTree.setStyle("selectionColor","0xE0E0E0");
mTree.setStyle("useRollOver",false);
mTree.setIsOpen(mTree.getTreeNodeAt(0), true);
My tree populates fine, and the handler I retrieve whatever item is clicked works great. However, the tree refuses to default to having that first node open.
I'm also interested in placing custom icons into certain nodes via the icon attribute I've set in the XML, but that will have to come later I guess.

I've never used the Tree component, so I'm just guessing here....

Ext. data source and Tree component

Im using tree component and XMLConnector here.

But the problem is that it publishes [type Function] in the

no actual xml nodes are visible, just bunch of [type
Function]
ive also searched for info / tutorial how to publish actual
xml data in the tree component but without any luck.
So what should i do and how ?

Tree component and loading xml files into text field

Hello and thank you for taking the time to read my issue....
I am making a simple self help application. I have a tree component that loads the different catagories and topics for my help app dynamically via an xml file...no issues there.
I then want it so that when the user cliecks on the actual topic that the TextArea component will load the info from another xml file using the name of the topic as the name of the xml file to make it that much easier for anyone to maintain this program.
So far the code i have is this.
myTreeListener.change = function(eventObject)
    var theSelectedNode = eventObject.target.selectedNode;
    var theSelectedNodeLabel = theSelectedNode.attributes.label;
    topicTextArea.text +=
I am a little fuzzy when it comes to loading the xml file in. Should i be loading html instead of xml is my other question as well?
Thanks in advance for your help
FG

Check out the Oracle XDB Developer's Guide, Chapter 3. There is an example of using BFileName function to load the xml files from a directory object created using create or replace directory. It works really well.
