I have a custom class that extends the Tree component so I can add some logic to the drag and drop functionality and not allow folders to be dropped inside folders.In the dragOver function, I am using:
var currNodeOver:TreeItemRenderer = TreeItemRenderer(indexToItemRenderer(calculateDropIndex(event)));
to determine the drop target, and setting:

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?

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
{label:'folder',children:[{label:'file1'}]}
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 have a Flex Tree component in my app. I set the icons for open and close.
BUT I can't find something about changing the default background-color from white to something different.
obviously there is no background-color setable in css...
I have created a MyTreeItemrenderer extending TreeItemrenderer.
However, I do not want any label, folder, disclosure icon nor icon. I want to dispaly every node of the tree with my own graphic like eg: a line, round image etc.,
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 have a namespaced Xml structure :
<rootlevel xmlns="http://www.wigo.org/simo"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.wigo.org/wigo ./schemas/lexicon.xsd">
<name>simulation</name>
[Code].....
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;
}
I want to customize the scrollbars on a mx|Tree component is Flex 4. I would like to mimic this functionality: [URL].

This code does retain the new color, but it also changes the color of nodes which are not visited at all. What am I doing wrong here? Is there any better way to achieve this?

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.
Here's a simple repro:

What happens is that icon2 shows for the East and West nodes but icon1 doesn't show for the Sales node. How can I get this to work?

I don't know if this is too difficult or too easy. My custom component is trying to listen to the main application's state changes using StateChangeEvent.CURRENT_STATE_CHANGE, but it's reporting its own state changes.
View 2 RepliesI have flexlib WindowShade component in repeater in my Flex + AIR application.
<mx:XML id="mainMenuXML"><items>
<item value="abc" />
<item value="xyz" />
<item value="lmn" />
</items></mx:XML>
Now in button1 click handler I am appending child in XML(mainMenuXML) resulting adding one more windowshade instance. But the problem is it opens all the windowshade instances. I need to maintain the opened states after adding a new windowshade instance.
For example:
Initially I get 3 windoshades with labels: abc, xyz, lmn all opened.
Now I close the xyz windowshade instance(by clicking on the header)
Now I click on button which appends child in mainMenuXML and also add a windowshade instance with some label "pqr". But now I see all the windowshade instances opened.
But it should be like abc, lmn, pqr should be opened & xyz closed(property opened="false").
How to maintain the opened true/false state of windowshade instances. I tried to add a property in dataprovider Bindable to opened property of windhowshade but didn't worked for me.
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'?
In Flex Builder 3, I am trying to access the main applications view state from within a component.On initialize I show the Loginpage-component.

View 1 RepliesIt's my understanding that view states can be useful when switching the layout of design elements. Such as, a loading page as one state and the main application design in another state. Is this the correct use of them? Additionally, I have a label in State1 and I cannot figure out how to access that label via actionscript. labelID.text = "New Text"; is not working.
View 2 RepliesI'm using Flex 4.5 and trying to take advantage of the new state groups feature. I have two States (call them readType1 and readType2) that both belong to the same stateGroup (call it readOnly). There are several places where I'd like to do something based on the current state, and it would be the same thing for the two read states. [code]...

So application resize into 616,919 . After that function finished move to current state like(currentstate='') But size not be changed . How can i set the size for current state?
I want to fade all the elements of the next state when transitioning from any state.I tried different things but I can't get it to work. And I don't want to manually add transitions for every state.

In my view I have a welcome screen:

Which is a pretty small component and I have panelContainer:

Whilst the user is reading the warm and fuzzy welcome note in the welcome state I want to be creating the big expensive panels state so taht when we switch there is no delay. Before the panels state is set panelView is null but I presume there must be an IDefferredInstance floating around somewhere that I can use to kick off the creation of the view. How can I get hold of it?
