ActionScript 2.0 :: Tree Structures - Replace Pointers To Nodes With Nodes Themselves

Jan 26, 2006

For 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.

Xml :: Get A Flex Tree To Display Only Specific Nodes?

Oct 9, 2009

How 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, 2010

I have a basic Tree built in Flex. The Tree works fine. I'm attempting to get a list of all of the visible nodes. I know there is a Tree.openItems, but that does not suffice because (for example) if you open all the items in your tree and then close the root, the invisible opened items are still counted.

Java :: Expand All Nodes In Flex Tree Using Timer?

private function openAllNodes(event:TimerEvent):void {

In my project I want to show the video like growing flex tree. So I tried flex timer based to expand node one by one. But if I open the first node then automatically close second time. If there is any other way to expand nodes one by one then let me know.

Actionscript 3 :: Check Boxes Just On Tree Leaf Nodes In Flex?

Sep 16, 2009

I'm having difficulty getting checkboxes on only the leaf nodes of a tree.Before anyone links it, I've seen [URL] and this isn't exactly what I need. I don't want a 3-state checkbox system including both branch and leaf.I understand applying the checkbox item renderer to a data grid but not on a tree.

Actionscript 3 :: Why Is IconField Ignored For Branch Nodes With The Flex Tree Component

Nov 18, 2009

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?

Javascript - Flex Tree View With Wrapped Text On Nodes?

Sep 8, 2010

I'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, 2011

working 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, 2009

I'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.

Actionscript :: Hiding Nodes In A Flex Tree Component Keeping The Children Visible

Apr 9, 2011

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'?

ActionScript 3.0 :: Expand Flex Tree On Open

Dec 17, 2009

I have a flex tree and every time it loads it only shows the one root folder, and i'd like it to show its full contents. I've seen loads of examples of people doing this, but just can't get it to work on mine. I think its because my tree is loading from an HTTPService, so whenever I try something it tries to do it before the tree has loaded, or something!

PHP Code:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="initVars()" height="400" width="150"

Actionscript 3.0 :: Way To Acces One Of The Nodes In The Tree And Trace The Data?

Sep 22, 2008

The problem is that a cannot acces the nodes in the tree using AS3 syntax. My guess is that the problem is nhe namespacing that is making it impossible. I have been sitting for hours trying to set namespaces or removing them, but i just cant get this to work. I can load the XML, but as soon as i try to walk down the tree i get no data output. Here is my actionscript so far:

var myNamespace:Namespace = new Namespace( "http://www.w3.org/2001/XMLSchema-instance" );
default xml namespace = myNamespace;
var xmlLoaderAvdelningar:URLLoader = new URLLoader();

[code].....

there is no way for me to acces one of the nodes in the tree and trace the data. To me the namespacing in the XML is very confusing, and i have no experience working with this kind of XML

Flash :: Flex 4.5: Tree - Make A Flex Tree Component Display The Children Of A Sprite In A Hierarchical Way

Nov 19, 2011

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?

Flex :: Tree - Filter Out "steps" - Any "array" Nodes And "preDialogues"

Mar 29, 2011

I have the following xml:

[Code]...

This code filters out "steps" and "array" successfully. However, if I uncomment the "preDialogues" code to try and filter out preDialogues, the question node gets skipped entirely. I can see why this happens, but what can I do about it? Its been awhile since I've done recursion. I thought I could return some sort of combined list, or something, but I can't get anything to work.

ActionScript 3.0 :: Flex - Loading Page As One State And The Main Application Design In Another State?

Apr 9, 2011

It's my understanding that view states can be useful when switching the layout of design elements. Such as, a loading page as one state and the main application design in another state. Is this the correct use of them? Additionally, I have a label in State1 and I cannot figure out how to access that label via actionscript. labelID.text = "New Text"; is not working.

Flex :: Get State Group / Actual State Object For Current?

Whilst the user is reading the warm and fuzzy welcome note in the welcome state I want to be creating the big expensive panels state so taht when we switch there is no delay. Before the panels state is set panelView is null but I presume there must be an IDefferredInstance floating around somewhere that I can use to kick off the creation of the view. How can I get hold of it?

Flex - 3-state "expanded", "collapsed" And "semi-expanded" Tree Control?

Aug 23, 2010

What I'm trying to do is have a 3 state tree expansion. I have three different icons for "expand" "collapse" "semi-expanded" which I want to use to show a partially populated tree control with all nodes initialized to semi-expanded state and then on clicking the "semi-expanded" icon it gets data from server and populates the tree and open that branch with "expanded" icon.

I tried looking for it but couldn't find anything close to it except the 3-state checkbox but don't know how to use it on 3 state icon when tree would only maintain 2 states.

ActionScript 3.0 :: Embedded Video - When I Click A Button On The Tree, It Runs The Respective Frames Then Returns To The Tree?

Jul 5, 2010

I have a intro to a picture of a tree which has buttons on it. The intro is an embedded flv video (not using the FLV component). The video starts on frame one and runs to frame 2. The tree is on frame 3.When I click a button on the tree, it runs the respective frames then returns to the tree. When the tree appears, the sound of the video is playing in the background.How can I make this stop?

Code:
stop();
MovieClip(lion_mov).stop();

Flex :: Override Child Node Controls In A Flex Tree Control?

Aug 20, 2010

I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:

private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....

I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?

override protected function createChildren( ): void
{
super.createChildren( );[code]............

Here is my tree tag:

<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />
