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" />

How can I make the node for, say, id==4 visible AND selected?
I'm using a flex combobox component in Flex builder 3 with sdk 3.4 and I'm trying to use it to expand and select the tree node that the user selected in the combobox component on the change event. However, I'm getting an error when I go to assign the combobox seletedItem to the tree selectedItem. Can you please help? What am I doing wrong?

View 2 RepliesI 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.

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 Flex tree control and im trying to select a tree node 3 levels down right after the dataProvider is assigned with a collection object like the following.basically treeItem1, treeItem2, treeItem3 are the nodes in the tree and treeitem3 is a child of treeItem2 which is a child of treeItem1. Assume these treeItem(1,2,3) are referenced correctly from the collection items.
my problem is that if i wait for the whole component to load completely then select the nodes, it open/select/scrolltoIndex correctly. However, if i were to select the node right after the dataProvider is assigned, then it doesn't even open or select (basically the this.treeService.selectedItem is always null).
this.treeService.dataProvider = oPricingHelper.getCurrentPricingSercicesTreeSource();
this.treeService.expandItem(treeItem1, true);
this.treeService.expandItem(treeItem2, true);
this.treeService.selectedItem = treeItem3;
this.treeService.scrollToIndex(this.treeService.selectedIndex);

i have a tree of nodes that i dont want some type of nodes to appear in the tree, i can check the data on tree item renderer for each specific node type, so i have one type that i dont want it to be shown as tree node, like it doesn't exist.

this.visible=false;
this.height = 0;
}
else {
I have a Tree object in my Flex code. It's width is 100%, and it is contained by a Panel with width=200. I am using a custom itemrenderer that extends TreeItemRenderer.I need the text in each node to word wrap if it's too big (as happens often). I have triedlabel.wordWrap = true;
View 5 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 Tree Control on which I let user add some nodes. When a node gets added I want to let the user edit the added control right away. How do I get the itemEditorInstance of a just added xml node?
View 1 RepliesI 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.
I need to have link buttons at end of each parent node as shown below:
-->(Parent)IBM Machines (rename | delete | disable)
Child 1 Child 2 Child 3
-->(Parent)Sony ( rename | delete | disable)
Child 1 Child 2 Child 3
Rename ,delete and disable are supposed to be link buttons. I have tried with label function and other methods also but not able get the exact requirement.
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.
I'm using Flex 3.3.
The tree should have a minimum row count of 4 and a maximum of 10 (beyond which it should display the scroll bars). So, I have a tree with rowCount="4" and I want rowCount to change up to "10" depending on the currently expanded nodes. In debug I can see two of the tree's properties which I could use[code]...
But these are not accessible from outside so I can't find a way to understand if the tree is expanded or not.
I want to have a tree node renderer which act as follow :Clicking on it change the node height.I have tried as follow : to create a custom class derived from UIComponentand then insert it inside the tree node renderer, but because of some reason it doesn't work as I expected.Here's the code :

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

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:
<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />
I am looking for the function or event, which is called when tree node is expanded/colapsed inside Tree object in Flex 4.5.

Is there any opensourse, free set of components for creating Flex mxml graphs? like aviary Peacock style ones with at least Drag, drop, and connect generators so each graph element could have or something like that. Framework should be opensource (like GPL, LGPL etc) BTW: I found one wary bacic made by Erno Aapa with Degrafa but I would really love to see something much more Flex 4 - mxml oriented and frienfdly.

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.
