ActionScript 2.0 :: Tree Component ... AddTreeNodeAt & Branch - Add An Item At A Particular Location?
Jun 7, 2006
I've got a tree component which works great, but I'm trying to add an item at a particular location (immediately after the item they select) into the tree. The problem is that I'm trying to add an item within a branch. I'm using myTree.getDisplayIndex(myNode) to get the position within the tree, but it gives the location relative to the entire list, but I need to get the position relative to the parent (which is what myNode.parentNode.addTreeNodeAt is trying to write to)...

I'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:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
[Embed("assets/icon1.png")]
[Code].....
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'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">
[code]....
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 was wondering if anyone had access to source code that would allow me to draw lines between objects. I have examples of the standard one line between 2 objects.
What I'm looking for is an example of how to draw a branching line. I.e. Starts as a line coming from an object and then branches out to other objects. I don't want to draw multiple lines from the same object because I need the objects to be related and the lines to have a settable property.
The added issue is that I want the number of branches available to be settable by the user. But if I can find code that dooes the branching lines, it probably wouldnt be too hard to tweek.

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 just read a comment at FlexExamples: One thing to note about the tree is that it is really just a list in which items are displayed. What that means is, you can't really drop somthing "into" folder unless the folder is open. Even in that case the user experience isn't quite right. So try moving everything out of one of the folders and then collapse that empty folder. If you drop something "on" the folder, it actually winds up between the target folder and the one below or above. This is indicated by the black line showing up as you move the mouse over the folders. If you "open" the folder (the only way to tell it is open is by the arrow) and then try it, you end up with an additional drop zone that is basically the bottom half of the opened, empty folder. This is also indicated by the black lines position.
It would be better if the middle section of any item could always be the drop zone for "add to this folder" and the top and bottom edges could be for dropping above or below respectively.I've just come to the same problem. Has somebody already managed this problem? In my case, I have dragMoveEnabled in the tree and offer the ability of dragging the tree items. But it is impossible to drag an item into another item that is empty. You can only drop the dragged item above or underneath an empty item.

I'm doing a drag and drop operation on a tree using some help from Adobe's quick Starts:[URL]
The code suggested is roughly this:
var dropTarget:Tree = Tree(evt.currentTarget);
var i:int = dropTarget.calculateDropIndex(evt);
myTree.selectedIndex = i;
[Code].....
EDIT: I forgot to post that my current workaround is setting the selectedIndex = -1 after I get my node:XML. I'm afraid that if something bogs on the processor the user may see it select then deselect.

I have a Tree Control inside my Flex Application which I want to edit on a doubleclick on a tree item. I found the properties doubleClickEnabled="true", doubleClick="startEditMode()", and editable="true". With these functions I can detect a double click and I can change the editable property to true based on a double click. The problem is that after I double clicked on a Item i have to click once more to really enter the edit mode. That doesn't seem to be intuitive at all

I have a XML based Tree Control. The XML Structure is recursive, so the children's can have the same Element as the parent. I now want to let the user add and remove the elements. Do do so I need to get the parent element of the selected Item. Following code I already collected together:
var selected:XML = treeControl.selectedItem;
parent.insertChildAfter(selected:XML, newElement);
I just don't know how to get to the selected parents node as there is no such method like treeControl.selectedItem.parent.

I have a tree control and I want to give the user the ability that he can move up and down the element he just selected with a up and a downbutton. The tree gets generated from XML. I managed to insert the selected item a second time at a other place, with the following code:
var parentXML:XML = XML(containerTree.selectedItem).parent();
var upperItem:XML = topContainer.source[containerTree.selectedIndex-1];
parentXML.insertChildBefore(upperItem,XML(containerTree.selectedItem));
but then I have the item there twice in the List. How can I remove to reinsert it?

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?

I have a Flex tree with an ArrayCollection as data provider. The collection holds an array of CategoryVO objects. Each object can have another array of CategoryVO objects inside it's "child" attribute. This way the tree displays the data correctly. Now I want to get the parent of a specific item, e.g. tree.selectedItem. Using XML as data provider the item parent is avaiable thorugh the parent() method. But I can't convert my data to XML. How can I get an item's parent? Perphaps using the tree's dataDescriptor?
