Jan 14, 2010I have an AdvancedDataGrid tree with a ArrayCollection as its dataprovider. Now, for instance, i drag a leaf from one node to another node. To catch the event I'm adding a Listener to dragComplete.

Actionscript 3 :: Why Is IconField Ignored For Branch Nodes With The Flex Tree Component
Nov 18, 2009I'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?
Actionscript :: Hiding Nodes In A Flex Tree Component Keeping The Children Visible
Apr 9, 2011I 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'?

View 1 RepliesFlash :: Flex 4.5: Tree - Make A Flex Tree Component Display The Children Of A Sprite In A Hierarchical Way
Nov 19, 2011I'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?

View 13 RepliesActionScript 2.0 :: Tree Structures - Replace Pointers To Nodes With Nodes Themselves
Jan 26, 2006For those unfamiliar with tree structures, tree structures are usually dynamic lists where every node has a pointer to two other nodes. They are arranged so it makes for faster searching and stuff and are very useful in programming languages that offer direct access to heap memory. Although I don't know if there would be benefits of making tree structures in AS would be of any help but I decided to have a go at it anyway. Since there are no pointers in flash I tried to just replace pointers to nodes with nodes themselves. Such things usually work in java I think because the language just automatically makes pointers for variables.

View 3 RepliesXml :: Get A Flex Tree To Display Only Specific Nodes?
Oct 9, 2009How do I get a Flex tree to display only specific XML nodes?
A sample of the XML data is below. Only the Grouper and Product elements should be displayed as branch and leaf nodes respectively; the Name elements should not be displayed. I can't use XSL or e4x to modify the XML as the Name elements' text is used as the label for the Grouper and Product tree nodes. Also, I cannot move the Name element to be an attribute as it needs to include a CDATA section.
It looks like using a custom TreeDataDescriptor is the way forward but I cannot find any examples of using one with XML.
<Grouper Type="ProductHeading" Id="" icon="drugIcon">
<Name>ASPAV</Name>
<Product Id="1002081" icon="genericIcon">

Get A List Of Visible Nodes In A Flex Tree?
Apr 20, 2010I have a basic Tree built in Flex. The Tree works fine. I'm attempting to get a list of all of the visible nodes.

Javascript - Flex Tree View With Wrapped Text On Nodes?
Sep 8, 2010I've spend hours searching for a way to put one paragraph of text in one tree node in Adobe flex. How can I do it? I created a simple tree view but the text is cut after the right border.
So I tried to create a tree renderer. In the renderer I specified width=100 and the text wrapped. But the height of the nodes was not being calculated properly, so the text over consecutive nodes overlapped and got messed.
So how do i do wrapped text in a tree node?
Flex :: Filter Tree Using ITreeDataDescriptor Without Reload And Close All Nodes?
Jan 18, 2011working with flex 4 and implementing filtering using ITreeDataDescriptor.Filtering worked as expected like the following code snippet however, i am trying to create a on-demand type of filter where user would type in the search clause in a TextInput, and as the user types, the tree nodes would be filtered on the fly.my implementation now is have user click on the search button and then reapply the dataDescriptor then reload the data. A big problem is that the whole tree collapses after setting the dataProvider again.any suggestion on how the on-demand filter can be achieved?
var dataFilter:ServicePricingFilter = new MyFilter();
dataFilter.searchString = this.txtSearchKeyword.text;
this.treeService.dataDescriptor = new MyDataDescriptor(dataFilter);

Flex :: Change The Appearance Of Nodes In A Tree Control Using An Extended TreeItemRenderer?
Nov 4, 2009I'm using a tree control that I want to customize. The data items in the tree's dataProvider have a property name that should be used for labeling the node, and a property type that should be used to select one of several embedded images for use as an icon. The simplest way to do this is by using the labelField and iconFunction properties.
However, I wanted to get started with item renderers and open the door for adding more complex customization later, so I tried making my own item renderer. I extended the TreeItemRenderer class as follows and used it in my tree control:
class DirectoryItemRenderer extends TreeItemRenderer
{
[Embed("assets/directory/DefaultIcon.png")]
private static var _DEFAULT_ICON:Class;
[Code]....
This code has no effect whatsoever, icon and label in the tree control remain at their defaults. Using trace(), I verified that my code is actually executed.

Flex :: Force A Tree Itemrenderer To Redraw During A Drag And Drop Operation?
Jun 11, 2010I have a tree control with a custom item renderer. The item renderer has different states that should be set while an item is being dragged over the item renderer. I understand from reading this post [URL] that the 'right way' to do this is to override the 'getCurrentState' method and append some text. I do that.
Now in my tree control I handle the drag over event and get a reference to the itemrenderer that is being dragged over and I set the boolean 'dragOver' property to true. Now I just need to force my itemRenderer to redraw. I can't figure that out. A workaround, is to just set the currentState of the itemRenderer.
how can I force my itemRenderer to refresh? (and I've tried calling validateNow, invalideDisplayList/Properties/Size, to no avail)
<?xml version="1.0" encoding="utf-8"?>
