All I want to do is modify the text value of the XML corresponding to the CURRENTLY SELECTED node in the tree. Everything is a piece of cake except actually changing 'abc' to 'xyz'.

I 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.
[Code]...
My Problem: I want to know the new node where the leaf was dropped. Actually i would have expected that in the event there is a property like dropParent. This is not the case.
I have a tree im my mxml that uses a XMLListCollection as dataProvider. Itīs XML is like:
<list>
<conta nome="Plano de Contas" id="1">
<conta nome="Creditos" id="2" />
<conta nome="Vendas" id="4" />
[code]....
How can I make the node for, say, id==4 visible AND selected?
I'm tring to increase the valueof an integer by clicking a botton. the idea is this,
[Code]...
about.buttonMode = true;
about.useHandCursor = true;
I have this on a MC I use for a button - and it works but only on HALF of the object - how can I make so it works on the whole object itself?
I know how to do this in other codes, but..if (condition1=true) AND (condition2=true) then... How do you do this in AS?
View 5 RepliesI have a flex application that's compiled with flex 4.1.I want that flex application to load an swf that contains the variable score and i want to be able to modify this variable.I wrote two versions of swf, one compiled with as2 code and the other with as3. this is my flex application:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"[code]......
DISCLAIMER: relatively new to Flex/AS3, I might be missing something obvious. After doing some research it appears that using the for(var property:String in object) does not guarantee the enumeration order of properties, however it doesn't say anything about modifying the VALUE that property points to as changing the for...in loop.
[Code]...
As a solution I can create a temp object to store the data while doing the loop on the original object, and then replace the original object with the modified data, but I'd like to know what exactly is going on.
So my question is, does the value of object property modify the looping order of the for...in construct? And if so, should it or is this a bug?
I have custom components which must adjust their text content based on space constraints. For example a component adds labels until there is no space, and then the content of the last label becomes "(x more)"
I do not have access to size of child controls before adding them. When in updateDisplayList, I make changes to the layout of the component, but for labels, lblInstance.text property fires events, which lead to updateDisplayList being called again. I know that updateDisplayList may be called more than once, but if there is a way to modify text without triggering events, that'd be really useful. For example, setActualSize method in UIComponent allows this kind of modification. Anything similar for text controls? Or do you have best practices for laying out and managing text content, in the context of custom Flex components?
so mouseOver and RollOver, and their respective outs work great as long as your mouse is actually over the item, or one of it's children. My problem is that I may have another UI component "between" my mouse and the item I want to process the mouse/rollover(maybe a button that is on top of a canvas, but is not a child of the canvas). The mouse is still over the component, there's just something else that it's over at the same time.
Here is a simplified code example detailing my question copy/paste that into your flex/flash builder and you'll see what I mean:Edit, I just made this more complicated and true to my actual problem, drag slowly, if you move your mouse further than the button in a single frame it kinda breaks, but that is just in this simplified version

I thought this was going to be easy! I would like to search an XML file for a particular data set i.e. set of nodes depending on a passed variable. However, storing a subset of my XML file via Code:var gallery = this.firstChild; and then searching 'gallery' as you would an array-using a for()-doesn't work since this.firstChild isn't returning an array
Code:
<gallery>

I have a tree with nodes , and a delete button , first user select the node and click this delete button , I want this node to be removed from the tree , Its not XML , every node in tree is of type Object
{label:'folder',children:[{label:'file1'}]}
I tried delete myTree.selectedItem (but compiler wont let me do it) also tried myTree.selectedItem = null (just unselects the item)and also how can I access reference to parent object of myTree.selectedItem ?
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:

I have an XML object like this[code]...

I've got some xml:
var xmlData:XML =

var buttonID = new Button;
var imageID = new Image;
var labelID = new Label;

I'm don't know how to get the value when node name is dynamically changed.
just trying to get straight how this works. Say I create some XML like so:

var sample:XML = <sample>
<items>

I am trying to customise the truncateToFit option in my Custom Tree. In order to do that i have to render a LABEL into my tree as the tree is not having the TruncateToFit property. I am begineer to flex, and i surfed a lot to see how they have rendered label inside a tree but i dint find any solution.Is my prediction right ? If it is right then how to render a label inside a tree component ?

How do you make the childAllowsParent property of an SwfLoader go from false to true, that is, how as a parent application do you set up security to make the child app's events and other properties accessible to you. To read the flex docs on this, one would think nothing could be simpler:
"This property [childAllowsParent] is set to true if the child object has called the allowDomain() method to grant permission to the parent domain or if a URL policy is loaded at the child domain that grants permission to the parent domain. If child and parent are in the same domain, this property is set to true . [emphasis added]" So, I'm in a development environment and want to load an swf from my own system via an SWFLoader and then be able to monitor its events within the parent app.

I would like to have a LinkButton programmatically selected.So I have a code like this:

I am receiving xml from a webservice call that contains a nil="true":[code]I used the Flex DataService (webservice) wizard to create the service objects for the cacheEntry component. This object will be serialized later on a different webservice call and stored in a database.I set a breakpoint on the set SystemFK method in the service object. It appears that the value passed in was an empty string!Allowing this value to be an empty string will cause problems in the webservice implementation in Java on the other side. Since the database value was null it is expecting a null in return, If I avoid setting this value, the serviceObject should send back a null which will make the database happy.How can I detect that a nil = true is present in the XML in order to avoid setting this value?

I have a tree being populated by an array collection. I don't have control of the data in the array collection and even when a node has no children it still has a "children" property that is causing my tree to treat every node as branch. I can do a simple check on the length of the array in the children property. If this is 0 I need the tree to display the node as a leaf, no disclosure icon. Any thoughts on how I can achieve this? It would be nice if there were a branchFunction like the iconFunction and labelFunction.
