Styling a tree component

Hi!
I would like to customize a tree component so that "nodes"
actually look like buttons.
i tried exporting the style and edit with flash, but that way
I can only edit the tree icons...
what I want is the Name of my node appearing inside of the
icon so that if i make the icon wide and look like a button, the
text should not be beside it....if i make any sense here..
maybe there's a way to use another component?
i only want one level below the node, so i could use an
Accordion but it doesn't work for empty containers (Canvas), it
always slides down a bit , even if you set the canvas' width and
height to 0 and the accordion to resizeToContent..
i hope i'm not too confusing and that someone can help me :)
cheers

Some people have adapted the tree control to make Treemaps.
Maybe that could help you

Customizing the Tree Component inn ADF Faces..

HI,
I am using the ADF Faces Tree Component and was wondering wheteher we
can use a specific theme instead of the default one..
The scenario's i am looking at are
1) Changing the Style of the Selected Node
2) Programatically can i assign a different styling for a Specific
Node (Previously Selected) in the Tree ??
3) And any info reg Enabling the Drag and Drop functionality ?? As of
now i don't think it is supported. Are there any plans of it being
supported in the furture releases??
Thanks

Hi,
1) See tree skin selectors: http://www.oracle.com/technology/products/jdev/htdocs/partners/addins/exchange/jsf/doc/skin-selectors.html
2) You can reference a managed bean for providing the inline style sheet on a component. This however only works when the tree is re-drawn and not dynamically
3) Drag and drop doesn't work in 10.1.3.x. In 11 this may work - havent tested yet - using a client listener component

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);

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?

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....
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:

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.

Tree component display problem when text too long???

hi all
whenever i use a tree component to display some sort of text, i run into problems when the width of the text being display for a node is larger than the width of the tree component.
Given: Tree tree1 with Node node1 and Child Node child1
When the text of either node1 or child1 is longer than the width of tree1, the text is displayed on its own single line UNDERNEATH the node images. this makes the text look like it does not belong to the group of children of a given node.
is there anyway to add maybe a text area or some sort of scrolling region to allow for any length of text for any node??
thanks everyone!

Yes, you can change the size of the tree node text field. Please see the "Tree Node Component Properties Window" section in the Help Contents within the IDE. Look at the info under the "Appearance" section.

How to build a form with a tree component

Hi, i'd like to know if it's posssible to build a form with
the Flash 8 Tree component.
My menu looks like a tree but the childnodes of this tree are
some form criteria that you can aditionate and post to a serveur.
I try to use the accordeon menu, and it works but my menu
must have dynamic heigth, and open all the boxes like the tree

Sans,
I am no Apex expert, but with a situation as "complex" as yours, have you thought about creating a VIEW that joins these 7/8 tables, placing an INSTEAD OF trigger on that view to do all the business logic in the database, and base your application on the view?
This is the "thick-database" approach that has been gaining momentum of late. The idea is to put your business logic in the database wherever possible, and let the application (Form, Apex, J2EE, whatever) concentrate on UI issues,

Incremental Loading of a Tree Component

I'm working on an explorer-type interface in Flex 2 for
browsing a remote file repository. It's a standard split-pane
affair with a directory tree on the left and a listing on the
right.
Because the entire directory tree can be rather large, I need
to load it incrementally as the user expands nodes rather than all
at once. I failed to find a relevant example so I wrote my own. It
works, but I'm new to Flex and am not sure if there's an easier way
or if there are any pitfalls to the way I did it.
I posted my code here:
http://xocoatl.blogspot.com/2007/01/incremental-loading-of-tree-in-flex-2.html
Any comments here or on the blog are appreciated; I'm
guessing that having a good example of the "right" way to do this
will be useful to many others.
Thanks.

i am also using another workaround using CSS trick(inlineStyle). if #{node.children} is null, i am placing an empty 10x10 white png image file over expand icon on tree node.
following code is nodeStamp of tree component.
<f:facet name="nodeStamp">
<af:group id="g1">
<af:image source="/images/spacer.png" id="i1" inlineStyle="border: 2px solid white; position: absolute; margin-left:-14px;" rendered="#{node.children == null}"/>
<af:commandLink text="#{node.name}" id="cl1" partialSubmit="true"/>
</af:group>
</f:facet>

On click at tree component it has to call SWF using XML

Hi,
I have created a flash file with name xmltoflash_tree.
Incules a Tree component named "tree01". On my first frame of
actions i have included "#include "test.as"". This is about my
flash file
In my Test.as :
import mx.controls.Tree;
var xmlLoader:XML = new XML();
xmlLoader.ignoreWhite = true;
xmlLoader.load("list.xml");
xmlLoader.onLoad = function(success:Boolean):Void {
tree01.dataProvider = this;
tree01.initBranches();
tree01.vScrollPolicy = "auto";
Tree.prototype.initBranches = function(node:XMLNode):Void {
if (node == undefined) {
for (var i = 0; i < this.dataProvider.childNodes.length;
i++) {
this.initBranches(this.dataProvider.childNodes
} else {
if ( (node.attributes.isBranch == "true") &&
!(this.getIsBranch(node)) ) {
this.setIsBranch(node, true);
if ( (node.attributes.isOpen == "true") &&
!(this.getIsOpen(node)) ) {
this.setIsOpen(node, true);
for (var i = 0; i < node.childNodes.length; i++) {
this.initBranches(node.childNodes);
I created an XML file named as "list.xml" :
Script inside this xml is :
<?xml version="1.0" encoding="iso-8859-1"?>
<node label="Select Application" isOpen="true">
<node label="Application1" isBranch="true">
<node label="Introduction to Application1"
isBranch="true" >
<node label="Testing1" />
<node label="Testing2" />
<node label="Testing3" />
</node>
</node>
<node label="Application2" isBranch="true">
<node label="Introduction to Application2"
isBranch="true" >
<node label="Testing1" />
<node label="Testing2" />
<node label="Testing3" />
</node>
</node>
I have folder with name Treehelp. All my files are in this
folder.
xmltoflash_tree.fla
test.as
list.xml
linktesting.swf
I have SWF in the same folder named "linktesting.swf".
I need to call "linktesting.swf" or any other swf files
included in the same folder. when i click on "Testing1/ or any
othe".
Have to write the script in XML to call the swf file. Help me
in this.

Ranjith Kumar. Bandi

Add oneMore attribute in the XML Nodes,
When selecting a Node in a Tree component you will recieve
all the data of that particular xml node. using that you can load
the Files
<node label="Testing1" filePath="MyFirstSWF.swf"/>
