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 :: Forcing Vertical Scrollbar Re-calcuation In A Hierarchical Tree Class Derived From Mx.controls?

Jun 28, 2011

I'm working (for my sins) on a Flex 3.3 project, which unfortunately cannot be upgraded to a newer SDK version at this stage, and have hit an issue with the custom hierarchical tree class (subclassing mx.controls.Tree) we're using. Excuse the spelling; the previous developer had a fear of dictionaries...

public class HierachyTree extends Tree
public function HierachyTree()
{[code].....

I'm using a solution somewhere between these two methods (basically, implementing ITreeDataDescriptor) in order to add live text filtering to the component, and it's working so far:

public class HierachyTreeFilteredDataDescriptor implements ITreeDataDescriptor
{
private var filter:Function[code]..........

The issue is that (with tree:HierachyTree) neither tree.maxVerticalScrollPosition nor the protected property tree.verticalScrollBar .maxScrollPosition updates when the search string is changed.I've tried calling invalidateList() and invalidateDisplayList() on tree — and calling invalidateDisplayList() and invalidateSize() on tree.verticalScrollBar — to no avail.

Ruby :: Storing A Filesystem Tree In Mongodb And Serve As Json To A Flex Application

Apr 17, 2011

I want to store a filesystem tree into MongoDB within a Ruby application, so we are talking about json/bson representation of something like:

/foo
/foo/one
/foo/bar/two
/foo/bar/three
/four

my aim is to store it efficiently and to serve it via json to an Adobe Flex application which will display it in a Tree component. which is the best solution in your opinion? this document suggests some options. i'd like to go for something like the first pattern (keeping in mind the limit of 16Mb document size) with this format:

Created an editable flex grid which exposes a method called getGridData() to javascript. I am using the JSON.encode() method of the [url]....library to convert the grid object's dataProvider into JSON before returning it.

Flex - Refresh Datagrid With Hierarchical Data?

Dec 3, 2009

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()).

Flex :: Sort AdvancedDataGrid With Hierarchical Data?

Mar 29, 2011

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.

Actionscript 3 :: Is There A Hierarchical List Component For Flex

Jun 9, 2011

I will implement this myself if I can't find it but after 30 minutes of searching on the web I'm a bit surprised this doesn't exist. Basically what I need is a hierarchical list component like the finder app on mac. I want the same functionality as a tree component but displayed as each level having it's own list resulting in multiple lists that depend on each other.

AS2 :: Post JSON Data From Flash With The JSON As The Body Of The Request?

Nov 5, 2010

I'm working on a Flash AS2 application that needs to post JSON data to a web service.In previous projects, I've used LoadVars.send() or LoadVars.sendAndLoad() successfully to manage this:

var send_lv:LoadVars = new LoadVars();
send_lv.data = JSON.stringify({some json object});
var response_lv:LoadVars = new LoadVars();
response_lv.onData = function(rawdata) {

In somepage.php, I can grab that JSON data using $_POST['data'].However, on this project, the developer of the web service requires the JSON content to be the BODY of the request (i.e., not a name/value pair). Is this possible with LoadVars?

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?

Flex :: Update Hierarchical Data Provider In Advanced Data Grid During Drag And Drop?

Nov 11, 2010

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.

Php - Flex Json Auto-udpate Datagrid?

Apr 17, 2011

I'm using Flex 4. Have PHP backend and mysql database with one table consisting of multiple rows. I take the raw data from the result event and decode it using JSON. I then dump the data into an ArrayCollection that I use as my datagrid's data provider.

My question is how can I tell when someone inserts a new row into the mysql table so that I can automatically refresh my ArrayCollection, thus seamlessly updating my datagrid one element at a time? Right now, it's just a one time call and the connection is closed. If someone inserts a new row into the database my program doesn't recognize, unless I restart it. I'd like to auto-update the AC whenever a single new row is inserted into the mysql database. Is there a way I can "listen" for this change?
