Actionscript 3 :: Indicate The Visit History On A Flex Tree Component?
Oct 26, 2009
How do I indicate the visit history on a flex tree component? I want to highlight the clicked/visited nodes to a different color and will not change after that, so that all the visited nodes will be one color. I tried adding an attribute to the underlying XML by
[Code]....
This code does retain the new color, but it also changes the color of nodes which are not visited at all. What am I doing wrong here? Is there any better way to achieve this?

I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?

How can you find out if a Flex Component (in my case the tree) is scrollable? I tried it like this
if (_listOwner.height < _listOwner.measuredHeight) {
// so stuff
}
from within the tree's item renderer but didn't succeed. Access to the tree's scrollbar is private so that I can't get the info that way.

i have a namespaced Xml structure :
<rootlevel xmlns="http://www.wigo.org/simo"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.wigo.org/wigo ./schemas/lexicon.xsd">
<name>simulation</name>
[Code].....
now, i have a labelFunction that passes in the xml..as an object but when i ran the programme, the tree view has each node, name, num_vars and variable as branches but the content in each of them was null and blank.
how can i properly display the namespaced XML on a tree view such that it shows every branches and elements in each branch?
private function treeLabel(item:Object):String{
var label:String = item.localName();
return label;
}

I have a custom class that extends the Tree component so I can add some logic to the drag and drop functionality and not allow folders to be dropped inside folders.In the dragOver function, I am using:
var currNodeOver:TreeItemRenderer = TreeItemRenderer(indexToItemRenderer(calculateDropIndex(event)));
to determine the drop target, and setting:

I'm using the iconField property of the Flex Tree to dynamically set the icon that a node should use. This works fine for leaf nodes but for branch nodes it doesn't seem to respect my iconField and instead just shows the default folder node.
Here's a simple repro:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
[Embed("assets/icon1.png")]
[Code].....
What happens is that icon2 shows for the East and West nodes but icon1 doesn't show for the Sales node. How can I get this to work?

I have a tree with a dataprovider which takes the following form:
<details name="Cars">
<contact_person>aaaa</contact_person>
<list>
[Code].....
That is I want to hide the contact_person and list nodes.Deleting the nodes from the dataprovider cannot be done.So what i did was to create a custom tree data descriptor by extending DefaultDataDescriptor.Then override the getChildren method and applied a filterfunction to the collection returned by super.getChildren.The problem is when i hide the 'list' node I cannot have the child nodes to show up.So is there any way I can hide 'list' but show the children of 'node'?

I am using the flex HTML component and I would like to clear the history of the control when it is taken off screen, so that when it comes back on again the history is reset.
The only thing I can think of at the moment is to set the HTML control to a new HTML control, although this is a bit of a pain.

I've got a Flex application that uses link buttons. As soon as I incorporated the link buttons (I assume) the Flex framework started putting history tracking elements below the app in the DOM. For example IE6-8 get an iframe element with id of ie_historyFrame, chrome/safari get a safari_rememberDiv and FF gets a firefox_anchorDiv.
Now, there would be no problem if these elements were hidden by the framework, but they're not. The sit underneath the Flex app (visually and in the DOM) and have a bunch of serialized history data.
I was wondering, is there a way to hide them through configuration or code? I know I could hide them via CSS but it just seems nasty that I'd have to use CSS for something that Flex is supposed to manage. I want the application to be site independent.

I have created a tree diagram using the 'Tree Component' in flash, and have linked it to my XML file:
<?xml version="1.0" encoding="iso-8859-1"?>
<node label = "Sports Club">
<node label = "Ball Games">
<node label = "Tennis" />
<node label = "Soccer"/>
<node label = "Bassball"/>
[Code] .....
If you haven't noticed yet, the tree diagram is nothing complicated, it branches out as 'ball games' and 'athletic games' with sub categories such as tennis, soccer etc. (or 100 Meter & Hurdles for Athletic sports.) Now I've managed to go this far, BUT, what i'm trying to do is that when the user chooses the subcategory e.g. 'Tennis' from the tree diagram, I need to get text into a blank text-box.

I was wondering if I can change the font style, weight, color, etc of an individual node within MM's tree component. I know you can use setStyle to change all elements, but I want to try to narrow it down to certain nodes. Also on a side note I was wondering if the tree component will render text as html.I am loading the content from an xml file.I was wondering if there is a way to have some of the nodes in the document render bold in the tree component.
Edit: I have found more info on what I would like to do and it involves the use of the CellRenderer API.

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.
Here are the contents of my XML file:
<node>
<node label="Desktop">
</node>
<node label="Documents">
[code]....
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.
