I'm using a tree control that I want to customize. The data items in the tree's dataProvider have a property name that should be used for labeling the node, and a property type that should be used to select one of several embedded images for use as an icon. The simplest way to do this is by using the labelField and iconFunction properties.
However, I wanted to get started with item renderers and open the door for adding more complex customization later, so I tried making my own item renderer. I extended the TreeItemRenderer class as follows and used it in my tree control:
class DirectoryItemRenderer extends TreeItemRenderer
{
[Embed("assets/directory/DefaultIcon.png")]
private static var _DEFAULT_ICON:Class;
[Code]....
This code has no effect whatsoever, icon and label in the tree control remain at their defaults. Using trace(), I verified that my code is actually executed.
I have a Flex tree control that holds a tree full of various types of objects. I'd like to change the label of the item based on this type (and other properties). I'd prefer to do this in a custom TreeItemRenderer rather than via label or labelfunction.It seems that whatever I do, I cannot typecheck nor cast the objects and thus I get [Object object] in the nodes of my tree. Here is my renderer:
public class MyCustomTreeItemRenderer extends TreeItemRenderer {
// Overriding to set the text for each tree node.
override protected function updateDisplayList(unscaledWidth:Number,

I have created custom TreeItemRenderer in which i am trying to draw colored Hbox bar at each node except root. Intially when i click on root node it opens first child node with bar but when i open leaf node it does not showing bar and removing existing bard from other few child nodes. Its calling itemrenderer on mouseonver eventhough i have disabled.Attaching Code here

I am using mx:Tree (in Flex 4), and assigned a customised MXTreeItemRenderer for every items. As the TreeItemRenderer contains a list with tileLayout, which means the height of every row is variable. So I have to set the tree's "variableRowHeight to true. When I was testing the tree, everything went well. But when I was using the vertical scroller, I met some problems:
The scroll bar did not move to the position I want. When I was scrolling the content, the scroll bar sometimes scrolled to a unwanted position (e.g. the head of the tree). When there are more rows, the problem is more obvious.When I was scrolling the tree, the images were flicking all the time.

I'd like to implement a custom drag on an AdvancedDataGrid tree structure, which only allows the drag on the branches (not leaves).I'm having much difficultly with this, trying to use the MouseDown event, but not having luck! I think I've got the mousedown able to figure out if the item is a branch of leaf. Any help on how to perform the custom drag with an advanceddatagrid?? [code]

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 currently am trying to add a custom class which subclasses UIComponent to both a tree and a canvas, but when I try to re-order the tree by dragging I get this error:[code]When I do not add the UIComponent to the canvas, this error does not occur, anyone have any knowledge as to why this happens?

I have created a custom multiline item renderer for mx:Tree component. Important to mention that my item renderer has two UITextFields in it. Sometimes (depends of the input data) only one of UITextFields must be shown, so when second UITextField is not needed I hide it and recalculate the height of my item renderer. According to my tests height is calculated properly.The problem occures when I do scroll of my tree. The error text is:
TypeError: Error #1010: A term is undefined and has no properties.

I 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 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?

View 13 RepliesI created a custom layout for a list, to be used on a mobile (android). I used this as example : [URL], using virtualization. Now the problem I have is with scrolling : when scrolling to the bottom of the list, there seems to be always a "bounce back", as if the list would have reached and as if the bounce/pull effect is taking place. But in fact the list has not reached the end at all, in fact I can not even scroll to the last element in the list. When going back from bottom to top, there's no problem at all.
I trace the top and bottom of the Scrolling Rectangle (Rectangle.getScrollRect) and there I can see that when scrolling down, the top and bottom parameters increase, but when releasing the touchscreen, all of a sudden the parameters decrease again with a certain amount, and so never reaching the end of the list. All my code is available on google project hosting : [URL]

View 1 RepliesIf you see google finance or other such charts, they usually have a small pentagon on the chart that indicates when the dividend was paid. Note the D markers in the screenshot [URL]. In this link you will see A,B,C,D .... along the charts X-Axis. If you choose a larger data range say 2005- 2010 , then you will see blue dividend markers along the x-Axis. Is there any thing in Flex that will allow us to do that?
View 1 RepliesI have a flex application and I want to add a new custom component with action script at runtime. This works fine. I have created my custom component and added the following code:

I'm new to Flex and am porting a pure Flash/AS3 app to Flex 4.5. I've created a custom MXML component based on BorderContainer
<?xml version="1.0" encoding="utf-8"?>
<s:BorderContainer
xmlns:fx="http://ns.adobe.com/mxml/2009" [code]...........
and it would work well, but here in Flex 4.5 I don't know how to do this.Also I've noticed that there is a dropShadowVisible="true" attribute, but not sure if/how it can be used for my purposes.And I'm not sure if scaling up/down a custom component is allowed in flex or I probably should use "Flex Effects" (but how?) and also set disableLayout="true"?
Using Flex 4.1, i'm trying to create a Tree element with a custom ItemRenderer (MXTreeItemRenderer). my problem is that whenever I fold and unfold a root item, the order of the items change.. it's weird like maybe the XML is not formatted properly.

I'm trying to recreate a UI for an application that my company makes in order to create an in-depth training companion to the application. One of the features is a weird tree view that works quite different from any tree view component I've ever seen, so I decided to create my own version of it as the Flash AS2 Tree Component doesn't have the functionality, and I haven't found any Tree Component for sale or download that works like that either. At first glance it seems like a standard Tree, except that it behaves differently if you click on the icon for each node than if you click on the label.
Some labels are links, some nodes can have 2 different labels, each with their own link, and most nodes have a second label underneath the label next to the icon (these don't have events assigned to them; they're just a quick way to view information). So anyway, I set up an XML file with all the information that I need (the easy part), but populating the whole thing, making sure each subnode can properly exist within each parentnode while allowing me to open and close them has been a real challenge.
Basically, I decided to use a whole bunch of loops to go through the nodes in the XML, but my lack of experience in using them is kicking my rear end. Basically, I need some code that can evaluate all the nodes in the XML and sort them within the proper hierarchies and then create all the clips in the stage to add the mouse events for opening, closing, and handling the links (which do not direct to the same event as when the icon next to that link is clicked).
Would anyone know how to customize the "tooltip" / mouseover popup window in a Candlestick Component?By default, It just displays open / high / low / close data, but I need to add additional details such as date, time, and a few others...I'm guessing this is simple one, using item renderers maybe, but I cannot seem to get my head around it, or find any decent documentation online..
View 0 RepliesThis is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event

I have a spark List with an item renderer and a tile layout. If I scroll by clicking with the mouse on the scroll bar and trying to scroll with the mouse wheel after that, there is a problem: The interval of the scrolling is oversized, instead of scrolling one item down (or up) the List scrolls 4 items down (or up).

are there any events that the scroller will dispatch when being scrolled?
