i gave the tree an ArrayCollection as dataprovider that i pulled from the database, and it contains the children, but the discloser icon wont disappear on an object that doesn't have a child.i think the problem is that the renderer doesn't recognize the leaf child, wich contains a children array of length 0, or null......
View 2 RepliesI'm having difficulty getting checkboxes on only the leaf nodes of a tree.Before anyone links it, I've seen [URL] and this isn't exactly what I need. I don't want a 3-state checkbox system including both branch and leaf.I understand applying the checkbox item renderer to a data grid but not on a tree.
View 1 Repliesi have TileList from which i'm dragging some stuff(image) to Tree (something like dragging sounds into playlist in iTunes), but when i can drop this stuff, i see only underline, this mean i can drop it only under or above some leaf-element in that Tree. How can i force it to hide this black underline and highlight leaf-element to which i wanna drop my stuff.

View 1 RepliesI have an mx:tree with with TreeItemRenderer as below.
Parent1 (Delete | Rename)
Child1
Child2
Parent2 (Delete | Rename)
Child3
Child4
Delete and Rename are link buttons
Now when i click Rename a popUp should be shown like
OldName : Parent1(Text Input showning present Name)
Enter New Name: Parent1NewName(Text Input for entering New name)
OK | CANCEL Buttons
Afetr Entering the new name,click OK,popup should be closed and need to get the value in the treeItemRenderer.
I have the logic to rename the Parent1 in TreeItemRenderer and also I m able to get the Parent1 in the popup OldName TextInput.But after entering the new name i m not able to get that new name in the TreeItemRenderer.
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.

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.
Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.
View 1 RepliesI have created a custom item renderer for the tree, i have added some children in create children function, my problem is that sometimes i need to show these children and sometimes i don't, depending on clicking on a button which also i have added at create children, the problem is that i had to create the item even if i don't want it to be visible, and removed it by making visible false, and this costs a lot of memory, i have tried to create it at buttons click listener but when scrolling the child disappears, and it may appear again if i keep scrolling up and down.. i am trying to add the child just when i need it to be visible, is this possible or i have to create it on child creation method?
View 1 RepliesIntroduction: I have a flat ArrayCollection of object's, which i group to create the dataProvider for an AdvancedDataGrid. In this AdvancedDataGrid i have different branches representing different type of tasks. I want to conditionally change the icon for the leaf nodes in the AdvancedDataGrid based on a date field stored in each object.For this purpose lets say each Task object contains an id and an updatedDate (Representing when the task was last updated). If the task has not been updated in the last five days (updatedDate+5 < today) the icon of that leaf node(Task) should be red, in constrast to the opposite the leaf icon in the AdvancedDatagrid should be green, e.g. like the image below. In this case task 35 has not been updated in the last 5 days, while 13 and 39 have.
Question: How do i change the leaf icons in the ADG based on the updatedDate of the underlying object? I would think that i have to extend AdvancedDataGrid and override some method, but which and how?I have seen easy ways of changing the open and closed icons on the web, but no way of conditionally changing an open node's icon :)

I am having some trouble with the flex Tree control.I have a control in my system and of course it is data driven.I have a group which shows a folder icon and that's fine but it also shows an expand icon when the item has no children.I don't what it to show the expand icon when the group has no children but I do want to show the folder icon, because it is different entities in my system.

By default, the iconFunction of List and Tree return only Class as the icon, which is for embeded images or iconUtility kindly provided by this site http:[url]...... It works very well with pre-created images.But what I really want is to accept a completely runtime generate sprite object, similar to what is done by Legend, with the color changes according to what the current status. I assume I could do something to make the ListBase to accept icon argument other than Class.

Do you have idea about the reason for that error and how to prevent it? N.B. The code that triggers this error is as a result for click handler. If before encountering this error change the selection on my yearsCb, everithing is fine. EDIT: I forget to specify that this error is thrown when it is a selected item in my ComboBox. It seem that after container that holds the ComboBox loses the focus, it doesn't recognize it's ComboBox child as having a selected item anyway (this problem arise only after the modal popup close.).
I'm using this AsyncHelper. I would like to create basic test case where I would like to dispatch event from the test method (by Parsley MessageDispatcher), catch this event in any other method and dispatch it back (by flex EventDispatcher).
This is my test case:

Is there a way to apply a renderer to a grid in a way so that it doesn't modify the values in the data provider? I have a datagrid and on one of its columns I have a customer renderer which overrides the set data function and converts the number value in the dataprovider to a word. My problem is that when I sort the grid by that column it sorts by the new value, whereas I want it to sort by the old value that was originally in the dataprovider. Here is my renderer:

I have a flex tree that worked perfectly fine when we set the defaultLeafIcon={null} and the folderClosedIcon and folderOpenIcon to {null}. We decided to put the icons back in and took out the nulls. Now they show up fine, but if you click on the icon instead of the label or the rest of the row, it seems to change the selected item, shows the highlight around the new item, but doesn't dispatch the ItemClick event. This makes it really hard to know that the tree's selected item has changed!
The weird part is that once you have clicked on the icon once and it looked like the selectedItem changed (or at least it applied that style), if you click the same icon again, it will actually fire the itemClick event. if you click any other icon, it does the same thing again, switching the selectedItem and styling that row, but not firing the itemClick event.
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 have a simple object defined by an object literal, and have a couple functions assigned to this object. Inside the functions, I try to access global variables, and it only gets undefined. The Flex debugger tells me the variables are just right up the scope tree.Yes, I know I can access Thing by using 'this', that doesn't solve my scope issue though.Project Flex Compiler Settings: Flex SDK 3.4, Require Flash Player 10.x.Example:

View 1 RepliesI'm using the tree component for a little Windows Parody I'm making. In my .fla, There's a tree component that loads an external XML file. I can't figure out how to add custom icons to my component, though.I know it's possible to set the icons for just the default folder and file icons, but since it's a Windows Parody, there'll be different icons for different file types, folder types, etc.In other words, I'd like to have a different icon for every item in my Tree component.
Here are the contents of my XML file:
<node>
<node label="Desktop">
</node>
<node label="Documents">

Also, I don't need to have an XML file loaded. If there's an easy way that does it all within Flash, please tell me. I just need to be able to handle events from the Tree.
i'm creating a reusable flex tree component. And i would like to stick in the itemclick funtion. So that when a user clicks anywhere on one of the tree's Branches. the branch expands.My problem is that i don't know how i can get the listener function to fire.What i would like to do is create the tree completely in as3. (no mxml). Normaly i set the itemClick on tree in the mxml. but i want to do this in as3. My component has alot more functions in it but i have deleted them so that it becomes easier to read. I Thought if i override the createChilderen function and add the eventlistener in there, that i would work. But no luck.
this is my code;
package
{
import mx.controls.Tree;
import mx.controls.listClasses.IListItemRenderer;

View 1 RepliesI'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?

This is not a problem with your Mozilla browser or your Flash plugin, but with certain websites that misidentify Flash 10 as Flash 1 due to a faulty detection scheme.
