How can you find out if a Flex Component (in my case the tree) is scrollable? I tried it like this
if (_listOwner.height < _listOwner.measuredHeight) {
// so stuff
}
from within the tree's item renderer but didn't succeed. Access to the tree's scrollbar is private so that I can't get the info that way.
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?

now, i have a labelFunction that passes in the xml..as an object but when i ran the programme, the tree view has each node, name, num_vars and variable as branches but the content in each of them was null and blank.
how can i properly display the namespaced XML on a tree view such that it shows every branches and elements in each branch?
private function treeLabel(item:Object):String{
var label:String = item.localName();
return label;
}

View 2 RepliesI'm using the iconField property of the Flex Tree to dynamically set the icon that a node should use. This works fine for leaf nodes but for branch nodes it doesn't seem to respect my iconField and instead just shows the default folder node.

I have a tree with a dataprovider which takes the following form:
<details name="Cars">
<contact_person>aaaa</contact_person>
<list>
[Code].....
That is I want to hide the contact_person and list nodes.Deleting the nodes from the dataprovider cannot be done.So what i did was to create a custom tree data descriptor by extending DefaultDataDescriptor.Then override the getChildren method and applied a filterfunction to the collection returned by super.getChildren.The problem is when i hide the 'list' node I cannot have the child nodes to show up.So is there any way I can hide 'list' but show the children of 'node'?

View 2 RepliesI've created a custom component with several inline item renderers that I use as a tooltip. The height of the component is unknown, as the data contents of the component are not known until runtime.
However, when displaying the tooltip, occasionally it extends beyond the boundaries of the flash application, thus, I'd like to be able to detect this occurrence and reposition the tip.
The problem is that the height and width of the component are, apparently, not available until after being rendered by the popup manager. (i.e. they are always 0)But, I do not know any way of finding out when the popup is actually rendered and, therefore, the height/width values available.

View 5 RepliesI have created a tree diagram using the 'Tree Component' in flash, and have linked it to my XML file:
<?xml version="1.0" encoding="iso-8859-1"?>
<node label = "Sports Club">
<node label = "Ball Games">
<node label = "Tennis" />
<node label = "Soccer"/>
<node label = "Bassball"/>
[Code] .....
If you haven't noticed yet, the tree diagram is nothing complicated, it branches out as 'ball games' and 'athletic games' with sub categories such as tennis, soccer etc. (or 100 Meter & Hurdles for Athletic sports.) Now I've managed to go this far, BUT, what i'm trying to do is that when the user chooses the subcategory e.g. 'Tennis' from the tree diagram, I need to get text into a blank text-box.
I was wondering if I can change the font style, weight, color, etc of an individual node within MM's tree component. I know you can use setStyle to change all elements, but I want to try to narrow it down to certain nodes. Also on a side note I was wondering if the tree component will render text as html.I am loading the content from an xml file.I was wondering if there is a way to have some of the nodes in the document render bold in the tree component.
Edit: I have found more info on what I would like to do and it involves the use of the CellRenderer API.
