Tree component index confusion

Hello,
I have a Tree component and need to access some nodes by its
index. This is to make a "move up/down" control. My idea, after
trying many, is to duplicate the selected (current) node up or
down, then replace the content of the original with the previous
node content.
I wish not to use previousSibling or nextSibling since, as it
seems, it doesn't recognizes either the origin and destination
nodes are in the same hierarchical level.
Working with some
index function doesn't works as I would expect when in 2nd
level nodes (that is, some child nodes of the first nodes) ; for
example:
-- node (index 1)
-- node (index 2)
-- child (index 3)
-- child (index 4)
-- node (index 5)
if the selected node is the second child of the second node,
index = 4, and then I substract this number to get the (supposedly)
previous child,, that is, in index 3, then I get the node in index
5.... my thought is that, when closed, the node in index 5 was
actually index 3.
Any clarification on how this could be happening is greatly
appreciated. Thanks,
Alvaro Medina

I also need to get a exact position in the nodes for a
selected item, such as in the following format
getTreeNodeAt(0).getTreeNodeAt(5)
in order to delete certain folders
thisTree.getTreeNodeAt(0).getTreeNodeAt(5).removeTreeAt(2)
How can I do this?? All i can get so far is node object by
thisTree.selectedNode ...

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

Tree Component - on itemRollOver

Hi all,
How can I get the item that was rolled over with the
"on itemRollOver" handle?
Documentation talks about a index property, which I cannot
get.
Thanks

Thankyou Donald,
Actually I was talking about the tree component (a flash
object). I wanted
to find out how I could get the index of the item I was
rolling over. I
found the answer at:

Save last selected and state for Tree Component?

I have a Tree component that refreshes its data everytime I
open the Tab containing it (doing a SQL call to return an index of
models). The problem is that everytime the dataProvider changes (a
new one overwrites the old one) with databinding, even if the data
is exactly the same, it loses its old state and selected node. Is
there any way to save this state/selected node when the
dataProvider updates?

good article on all aspects of trees including your issue.

Disable Cell of Tree Component

I want to add a property to the rows/cells of Tree component,
by which I can enable and disable the clicking of the rows. Any
idea?
Thanks in advance
Ankur Arora

Haven't tried this, but its an idea:
Tree inherits from the List class...
so you have itemRollOver and itemRollOut events which lets
you know the index of the item
and a selectable property (at the level of the list (or tree
in this case), not for a specific cell or index)
so, you could listen for itemRollOver and set the selectable
property of the Tree based on whether the index that you rolled
over is supposed to be selectable or not.
Like I said, I haven't tried it.

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:

Ext. data source and Tree component

Im using tree component and XMLConnector here.

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

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

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,
