Flex :: Parent Data Calculated From Children Fields In Hierarchical Data Structure
Jun 17, 2009
In flex 3 I have a hierarchical data structure. I would like to display the content of it in a tree. My problem is that I have nodes which data calculated from children nodes. How to structure the hierarchy to make automatic changes to those parent nodes, if their children's data changed? For example:
Every node has a warning flag. If some of the children warning flag changed to true, then the parent warning flag should change automatically set to true. A node integer field is the sum of the children integer fields, and if any of the children changes, the parent integer field "calculates" the sum immediately. Is there an easy solution wit good structuring changes happen automatically, or I have to make some custom functions?

I am trying to drag and drop hierarchical data in the same advanced data grid, and I would like the data provider to updated when the ADG is updated. (I want to be able to save and load this tree, so it is important that drags and drops are saved.)
[URL]
The sample app has an ADG showing hierarchical data as well as flat data. The first column of each datagrid shows the rowindex of the underlying data.
If you rearrange the items on the left ADG, the row indexes become unordered. If you click traceTree you see that the data provider is not in order.
On the other hand if you do the same on the right, the row numbers stay ordered even when the objects move around and if you click traceFlat, the data provider is in the order shown on ADG
My goal is to have the data provider order match the ADG order for the left grid which is displaying hierarchical data.

how can I refresh the displayed data in a Datagrid when the underlying ArrayCollection changes?
<nmoschitz:dataProvider>
<mx:HierarchicalData source="{arrCol_groupedData}"
childrenField="accounts"/>
</nmoschitz:dataProvider>
Calling a simple refresh (like with a simple arraycollection as a dataprovider, or with a refresh on the Grouping Collection) does not work. Also re-assigning the arrayCollection to the Hierarchical Data and then assigning this one again to the Datagrid does not work (even with calling invalidateProperties() or validateNow()).

I have an AdvancedDataGrid with a HierarchicalCollectionView as its dataProvider. When I view the grid with the dataset I'm working with, and click the header of the column I wish to sort on, everything works perfectly. It sorts it hierarchically exactly how I would expect it to.What I want to do now is have the grid already be sorted when it is shown to the user. Is there a way to do this programatically? I can't for the life of me figure out how to do this, and clearly it's possible since the AdvancedDataGrid has this built in.[code]This appears to do something as far as sorting goes, but it doesn't sort it in the same way as clicking the column header. "startDate" is a property of an object in theDataSource by the way.

As ArrayCollection in Flex is limited, I'm looking for a data-structure that something like LinkedHashSet in Java, LinkedHashSet maintains a doubly-linked list running through all of its entries,it defines the iteration ordering, which is the order in which elements were inserted into the set (insertion-order).But there is little information about Flex data-structure

Shouldn't this last output be the number 1? I want to use this number to call the correct node for each clip,

Scenario 1: Within some 3D container object, I would like to add two Cubes: one without any transformation, and one with small position, rotation and scale adjustments. After adding those two cubes, I would like to also transform the container's position, rotation and scale.
Scenario 2: In a 3D character's body, it consists of many hierarchical children (and subchildren), each having various transformations over the course of an animation.
How do I calculate these individual 3D object transformations efficiently? Can it even be possible to do this with only one VertexBuffer3D? Or do I need several VertexBuffer3D to keep track of each objects? Using multiple VertexBuffer3D seems like it could hit a limit (but I haven't read enough of the Stage3D / Context3D documentation to know for sure).

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?

Newbie to XML here and I have what I *hope* is an easy problem, but I just don't know the answer. And as I have to try and show this by Monday, I'm sort of stuck. I am trying to pull in information about houses via an xml file. Each house has 1 address, 1 owner, 1 description, and about 6 photos. I have no problem accessing the address, owner, etc, and I can always access the first photo, but whenever I cycle through the photos, I seem to cycle through the first photo for every house, not every photo for each house.
Basically, I need the children <images> to go up by one, without the the parent going up by 1. I am hoping I am describing this well. My code looks like this:

I have an actionscript-instantiated component in a containment hierarchy; it extends ComboBox, but it's instantiated dynamically--you never know when you're going to need it. Somewhere up in its containment hierarchy, there's a thing which extends NavigatorContent which logically is the right place to put the valid values for said combo box. What's the canonical way for that child component to get a reference to that set of valid values?

I have a parent w/ a popup child. When parent loads, I have to call a function within the popup without showing the popup (thus, I load "pupLove" but don't include it in layout)....I then pass this data to the parent. When the user manually clicks another button to open the popup, the same function is called & data passed to the parent. However, I am not able to pass dg.length to the parent. I believe the root problem is that I am loading "pupLove" & thus the parents are getting confused.....I'm guessing if I get rid of "pupLove" I can pass the data correctly but will need to call the child's function at creationComplete of the parent....how do I do that?Here's my parent:

I have a Flex tree with an ArrayCollection as data provider. The collection holds an array of CategoryVO objects. Each object can have another array of CategoryVO objects inside it's "child" attribute. This way the tree displays the data correctly. Now I want to get the parent of a specific item, e.g. tree.selectedItem. Using XML as data provider the item parent is avaiable thorugh the parent() method. But I can't convert my data to XML. How can I get an item's parent? Perphaps using the tree's dataDescriptor?

I was just wondering what the best data structure would be to use to represent data objects in a side scrolling game, basically the stuff the user can't see isn't on the stage so I would generally create a custom class to define its properties (x,y,weight,type, derp, etc) and then push that into an array and as the user moves forward I project the info from the array while checking if their x position is.
The problem that can occur is that the user can move left and right so whats the best way to keep track of the indexes?

I'm making a game and I need to represent a "layered" circle in some clever datastructure.A circle can have any number of layers. Each layer has a number of "slices", they can be of different lengths and pieces can be missing. The innermost layer is always a full circle.Each segment has a color, multiple segments with the same color can be next to each other. Realistically a circle wont have more than about 40 layers or about 1500 individual slices.I will need to be able to easily find adjacent pieces to a specific piece, see if a piece is "hanging in free air" (imagine gravity towards the center), and to remove pieces leaving a hole in their place.

I want to separate the data from the PHP call to Different CollectionArrays So that I can use the data for a bar-graph;
I created a static version of the bar-graph and separated the Collection array manually I don't want this done manually I need to do it dynamically. So what I am trying to understand is where to put the event-listener how to add to a collectionArray then once the collection array(s) are built. use that information to build the bar graphs...

I've got a Gridcolumn in a Datagrid (Spark). The Column's dataprovider is a Number value that gets updated via Binding.Now, without an item renderer the cell displays the correct values.If I set an item renderer, I can't access the values in this renderer.My renderer looks like this, so nothing really do here (for now) but to trace the value, but the value is always NaN.
<?xml version="1.0" encoding="utf-8"?>
<s:GridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" width="100%" height="100%" >[code].......
without the renderer, the column displays the correct values, so apparently the DefaultGridItemRenderer works fine.As requested, here is my Datagrid;
<s:DataGrid id="dataGrid" dataProvider="{_listItems}">
<s:columns>
<s:ArrayList>[code]..........
_listItems is an ArrayList with instances of a model class, which has (amongst others) a property called change of type Number.

I have been goggling a lot to find anything with link-based data visualization in Flex 4. something like below screen shoot (made using Ravis). Where user can drag these nodes, without removing the links and on double click of any node we can set some properties for that particular node. I found this Ravis (Birdeye), but not much of examples and support is available for that.

I have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.
I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).

I have loaded an XML file and I am populating several text fields with the data. For the first name and last name fields, I would like to combine the data into one field for appearance sake, but for some reason, only the first name data is appearing when I run it. It seems to be truncating the last name. My code looks like this:PHP Code:Obj.Name.html Text= xmlFile.name.first +xmlFile.name.last;Do I have some syntax wrong? Is concatenation allowed in AS3?
