I have a window with a tree (each node is a category). I have a dataprovider what contains picture url and category. My goal is to filter the view with only selected node. Several nodes may be selected in the time.
View 1 RepliesI have a Flex tree with an ArrayCollection as data provider. The ArrayCollection is composed by objects linked eachother by the "children" field (that is an Array containing other children objects)

I have a advanced datagrid and populating some data by using arraycollection. And i am filtering the arraycollection, the arraycollection index got changed.
Arraycollection:- [0] - name: abc
[1] - name: hello
[2] - name: hello1
[3] - name:hai
after filtering the arraycollection as 'hell' , the array collection is displaying like the below:
Arraycollection:-
[0] - name: hello1
[1] - name: hello
Can i know the reason why the index got changed after filter it?
* no server side code for filtering. it is only flex side filtering.
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 have been trying to populate a tree control via an httpservice that uses php to talk to a database. The queries work fine and the data comes back in the following format from php:
echo "<root>";
echo "<topic>";
echo "<sectioncode>$sectioncode</sectioncode>";
echo "<children>";
echo "<labtitle>$title</labtitle>";
echo "</children>";
echo "</lab>";
echo "</root>";
Flex can see this and interprets the heirarchy fine unless i try to format the resultformat in the httpservce (if i do that it goes a little nuts). The results from the php query to the db come back as an ArrayCollection with each containing a "root->topic->sectioncode->title" type of structure (which is what I want). When I go and try to use this Arraycollection as a dataprovider for a tree control, it doesn't work at all. When I use the arraycollection as the dataprovider I get [object,object] for every row in the tree and there is no parent/child structure.
Ideally I would like the title to be a child of the numbercode, but when i try and format the return from xml like that the number becomes and object without a value and the title becomes a child. I have a feeling that I am missing something in the php return to show the structure to flex more clearly and also something in the tree to implement it as the data provider better. Here is the code that I am using in the tree:
<mx:Tree x="25" y="48" height="451" id="ilabtree" dataProvider="{labarray}" labelField="@title" width="152" textAlign="center"></mx:Tree>
Let's say I had an ArrayCollection like this:
public var ac:ArrayCollection= new ArrayCollection([
{item:"dog", group:"Animals"},
{item:"orange", group:"Fruits"},

How would I create a Tree component in Flex 3 that uses the groups as nodes, with the appropriate items listed under each node?
I have an ArrayCollection which has several employees and departments.Each employee belongs to one department. How can I find out how many employees are belonging to the same department from the said ArrayCollection.In database we use join query to do this, but how can I do this by using an ArrayCollection in Flex?
For Example

How can i fetch these values from arraycollection in flex? is there in inbuild function or property provided by adobe.
I have a requirement to filter the tree similar to that of flex builder-->preferences wizard tree.
My tree dataprovider is arraycollection of industries. Each industry has a list of sub industries and further, say upto depth 5.
So when we type in a string to filter, only the node having this string along with their parent hierarchy should be returned.
How can we implement this using flex?

View 2 RepliesI've got a couple trees that I allow a user to drag and drop from one to another, works great except one apparent limitation. I'm picking up where they drop it in the list and adding it to the dataProvider manually. The user can drop it everywhere except after the last child of any particular node it seems, since it reads that position as being between the node and it's next sibling.
It seems the best way to deal with this is to add something like a dummy leaf so the user has something to drop the item in front of. I don't want this leaf in the dataProvider, so is it possible to add a leaf (or a folder) to the tree without adding it to the dataProvider?
I want to add an indicator on a tree node icon , meaning , for example like in eclipse when there is an error the icon get a special small indicator on the regular icon. how can i do that?
View 1 RepliesI have a object that is extended from arraycollection. This object has to access and manipulate the arraycollections source object. When this happens, the local sorted/filter copy of data goes out of sync with the source data. To line things up correctly, the sort/filter needs to be re-applied.
To do this normally, you would call refresh() on the arraycollection, but this also broadcasts a refresh event. What I want is to update the sort/filter without dispatching an event.Having looked into the ArrayCollection class, I can see it is extended from ListCollectionView. The refresh function
public function refresh():Boolean
{
return internalRefresh(true);
}
is in ListCollectionView and it calls this function
private function internalRefresh(dispatch:Boolean):Boolean
{
if (sort || filterFunction != null)
{
[code]....
annoyingly, that function is private and so is unavailable to and class that extends ListCollectionView. Also, a lot of what is in the internalRefresh function is private too.Does anyone know of a way to call internalRefresh from a class that extends ArrayCollection? Or a way of stopping the refresh event from being dispatched when refresh is called?
I'm using XML to populate a comboBox Component. How do I get the aactionscript to trace which number in the array the choice is? So for example is my choices are:
choice A
choice B
choice C
on the dropdown box, whne I click "choice A" I want it to trace "0" because that's it's place in the XML, or if I click "choice C" it will say 2".If i use "length" it will tell me how many. I need to know what to use that tells me which one.
I'm currently modifying an xml menu found in the kirupa tutorials and Ive gotten stuck. I want the menu to filter into different columns depending on a xml node called type="". So far I have this but I cant seem to get my head around how to filter the menu.
Code:
GenerateMenu = function (container, name, x, y, depth, node_xml) {
var currNode;
var currItem;
var currMenu = container.createEmptyMovieClip(name, depth);
[code]....
at the moment all I've tried to do is filter the menu with an if statement to only display the type node with "web" in them. As soon as I undestand how this is done I sohuld be albe to do the rest myself.
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);

I have inherited a Flex air project and have not worked with trees before. The tree is displaying an xml file hierarchically. The user can make a change to the data. I need to save the data of the entire tree to a file.I can save the currently selected item to a file, no problem. But I need to save all the data from the root of the tree, forward.I would think I could make a copy of the tree, and set the selected item of my new tree to root, or something. Sort of like this pseudo code:
var treeToSave:Tree = new Tree (editedTree);
treeToSave.selectedIndex = 0;
// now save treeToSave to file...
This creates a compile error, but hopefully you can see what I'm trying to do.

View 2 RepliesI have a project, where I am selecting a scene based on the information in a Tree's XML data provider.
As you can see in my XML below, I've got two scenes. Each have a view001 attribute, which only exists at the highest level in the tree hierarchy. What I need to do, is to find out the information stored in this attribute.
I need to see only the one that contains the currently selected item in my Tree (named treeView, dataProvider is the xml file, labelfield is .@name).
One problem I do know I have, is that I'm only checking the first parent(). My problem is, that I don't know how to "step" through the XML, to go up one parent at a time.
This is my function:
public function getParentItem():XML {
var selectedItem:XML = new XML(treeView.selectedItem);
while(selectedItem.@view001.toString() == "") {
[Code].....
I have a XML based Tree Control. The XML Structure is recursive, so the children's can have the same Element as the parent. I now want to let the user add and remove the elements. Do do so I need to get the parent element of the selected Item. Following code I already collected together:
var selected:XML = treeControl.selectedItem;
parent.insertChildAfter(selected:XML, newElement);
I just don't know how to get to the selected parents node as there is no such method like treeControl.selectedItem.parent.
I have a partially populated Tree component and I have to invoke a remote service when User expand (not when he select) a node to retrieve it's leafs. How I know witch node have bee selected.
