[flexcoders] Re: Tree component
I tried this, but i cant expand and collapse nodes. There are no possibility to do this. I have extended Box and implements IDropInListItemRenderer. I tried also to extend TreeItemRenderer and add some child on set data depending the depth of the node, but no child appear, only folder icon and label. I want to say that dataProvider for the Tree is an array of objects, objects that have a property children array of other objects.

[flexcoders] Re: Tree Component openItems and refresh dataProvider issue
I am looking for a solution to the same issue. As far as I understand it the problem is that the new dataProvider elements are assigned different UIDs from the UIDs stored in your openItems array. The UIDs assigned to the old dataProvier are different than the UIDs assigned to the new dataProvider. I read a solution somewhere that you can create a new ArrayCollection class that implements the IUID interface and use that for your dataProvider but that doesn't solve my problem as I am using XML for my dataProvider. I'll keep you posted if I find a solution. --- In flexcoders@yahoogroups.com, flashalisious [EMAIL PROTECTED] wrote: Ok I have working with the Tree to display a list of files for to users. There are two branches. Each labeled with the user name. Any files they have uploaded are listed under there branch. I will have an upload file button as part of the view. When the users uploads a file I fire off an AMFPHP call to get the new file list data so that I can update the tree with the new files name. Here is the issue that I am running into. I am storing the Tree's openItems property into an Array because after the user uploads the file and the dataProvider gets updated the branches close. I would like the user to be presented with the branches they had open before they uploaded the file. Ever time a branch is open I say myArray = mytree.openItems; If I put a button all the stage and on the click I say mytree.openItems = myArray; The tree opens the branches stored in the Array. If I make an AMF Call and the dataProvider changes the same function for setting the openItems proporty does not work. I even tried using mytree.validateNow() before I set the openItems propory. Anyone have thoughts on how to make this work. Seams like a bug to me but I am not sure. -Matthew
[flexcoders] Re: Tree Component openItems and refresh dataProvider issue
Are you resetting the data provider or just updating it? I find that if I just update the data provider by inserting/removing elements the Tree reflects the change appropriately. One bug I've hit, which might be what you are experiencing, is that if I remove the Tree from the stage and add it later then all branches will appear collapsed even tho the property openItems correctly lists the open nodes. The workaround is similar to what you describe: https://bugs.adobe.com/jira/browse/SDK-14892
Re: [flexcoders] Re: Tree Component openItems and refresh dataProvider issue
override the set dataProvider; then store the openitems, selecteditems, etc... call super.dataProvider = provider; openItems=storedOpenItems; validateNow(); selectedItems=storedSelectedItems; validateNow(); as for amf calls, I have a method which gets the instance from the dataprovider and adds it to an array. then i set the value in the tree.

RE: [flexcoders] Re: Tree Component openItems and refresh dataProvider issue
I didn't quite follow Ryan's suggestion. The problem in general is that the selectdItems array has to contain references to items in the dataProvider. This will not be the case if your replace the DataProvider. Using the API to update changed items is an ideal solution if possible in your case. Another solution would be to keep a list of ids of the open nodes. You only need to keep the end child in the list. Then, when the dataProvider is refreshed, recursively process the dataProvider looking for ids in the list. When found, climb the ancestor chain opening nodes as you go until you reach an open node or root. Really ugly, but pretty fast if your data is not huge.

I won't say what you are doing is wrong, but it is very rare that
itemRenderers should be manipulated directly. What you are doing will
die if someone closes a branch. I really suggest that you re-examine
your approach.
The normal way to do what your are attempting would be to have a
selected attribute on your nodes, and have the renderer use that to
set its selected state. To set all the checkboxes to selected, loop
over your data as you are doing, set the selected attribute as you wish.
The tree will automatically display the results.
One nice thing about XML is that you can add attributes on the fly. So
even if your source xml does not have a @selected attribute, you loop
can add one. I do that in this example, which is for a DataGrid:

at first I was thinking of keeping a register of what was opened so I
knew what to close.
you dont have to. mx:tree has a property called openItems ..this has a
reference to all the opened items. all you have to do is check whether
anything is opened during a Tree.itemOpen event
eg
mx:Tree id=tree1 itemOpen=treeOpened(event)
public function treeOpened(event:TreeEvent):void
{
if(tree1.openItems.length 1)
{
tree1.expandItem(tree1.openItems[0], false);
}
something like this

if(TreeListData(super.listData).hasChildren) {
graphics.clear();
graphics.beginFill(0xF4C403,1.0);
graphics.lineStyle(1, 0xF4C403, 1.0);
graphics.drawRect(0, 0, unscaledWidth, unscaledHeight);
graphics.endFill()
}

I've

row
colors during the animation.
Possible workarounds include overriding onTweenUpdate() and
manually
tweening the backgroundColor of each row yourself. You might be
able to
get away with writing your own TreeItemRenderer where each

was encompassed in an HBox with backgroundColor set. However I
think
since renderers are re-used, you'd have to write some code to make
sure
that as each renderer is re-used its backgroundColor is changed to
maintain the color ordering prescribed by that row's depth.
If you find the shifting of colors too ugly, you can change your
openDuration to 0 so that there is no animation and the items just
open
with the correct background row color.

Hi,
Maybe try something like this:
mx:Tree nodeOpen=getNodes(event.node) /
you might want to store a reference to this node rather than using
contentMgmtTree.selectedItem.
So you script block might look like this:
public function getNodes( treeNode )
{
treeSelectedNode = treeNode;
EventBroadcaster.getInstance().broadcastEvent( getTheNodez,
treeNode.getData().oid );
}
//and for adding the nodes
public function addTreeNodeUnderSelected(treeNode:TreeNodeVO)
{
var tempNode:TreeNode = treeSelectedNode.addTreeNode( treeNode );
//or break it down even further with this
//var tempNode:TreeNode = treeSelectedNode.addTreeNode(
treeNode.label, treeNode );
if( treeNode.hasChildren == true )
{
tempNode.setProperty( 'isBranch', true, true );
}
else
{
tempNode.setProperty( 'isBranch', false, true );
}
}
The only real difference is that I store a reference to the selected
node from the nodeOpen event using event.node. This is then what I
would use to add the child nodes to.
See how that goes.

Hi Everyone,
I have looked through old messages in this group and did not see
anything that addresses my question - or at least it was not clear
that it did.
Here is what I am trying to do.
Using the Cairngorm framework, I am making a remote call to my server
to retrieve something I wrote called a TreeNodeVO ( which has a public
label property ).
My ViewHelper adds the Root node like this (which works ):
public function addRootTreeNode(treeNode:TreeNodeVO) : Void {
view.contentMgmtTree.removeAll();
var node:Object = view.contentMgmtTree.addTreeNode(treeNode);
if( treeNode.hasChildren == true ) {
view.contentMgmtTree.setIsBranch(node,true);
}
}
when I open the tree node, I make another remote call to get the
children as an Array of TreeNodeVO objects.
The ViewHelper method to add the other nodes under the opened node
looks like:
public function addTreeNodeUnderSelected(treeNode:TreeNodeVO) : Void {
trace(treeNode: + treeNode.toString());
var node:Object =
view.contentMgmtTree.selectedItem.addTreeNode(treeNode);
if( treeNode.hasChildren == true ) {
view.contentMgmtTree.setIsBranch(node,true);
}
}
what I see happening is the root node renders correctly as a folder
with the right label. When I open the folder the server is returning
the correct array of TreeNodeVO objects but what is rendered under the
root node is a document icon ( which is correct ) but with the label
[type Function],[type Function],...
Can someone please point me in the right direction on the correct way
to add nodes that DO NOT use the XML model?
Any help is greatly appreciated.
Thanks

Thank you for the response, but that produced the same results.
Other thoughts?
I assume that since my TreeNodeVO has a label attribute, that is all
that is really required? Is it having trouble understanding this VO?
Thanks again

RE: [flexcoders] Re: Tree component help - please
I think the label property need to be at the top level of the treeNode.
So your example:
var tempNode:TreeNode = treeSelectedNode.addTreeNode(
treeNode.label,
treeNode );
Should work.
Remember when accessing the treeNode, use the TreeDataProvider API, like
getProperty(label), and getData()

RE: [flexcoders] RE: Tree component confusion
Here is an example posted on the MM forum some
time ago:
Tariq, if you are listening, maybe this
should go in your examples.
Tracy
There is an unexpected
behavior with the dropLocation: Sometimes it does not return the correct
integer. For example, expand all the nodes and try to drag node
Four into the first(0) position in branch
one. GetDropLocation() returns a 1 not a 0
as I would expect. If anyone has any insights I would like to hear, as I am
fighting with this situation in my own application.

Subject: [flexcoders] RE: Tree
component confusion
My objective is to allow the user to drag a tree node and
drop it on another node, and then reflect visually the changes he/she has made.
I since learned this is a lot more complicated than meets
the eye because the index of the drop location seems to change. From what I
have seen, the moment a branch opens, its index becomes 0, and when it's
closed, it's index becomes relative to its parent node. So if Node A is the
topmost node, and Node B is its child node, while Node B is closed, it's index
is 1, but the moment I open Node B, it's index becomes 0.
This is a problem because the only method I see that I can
use for my purpose is the addTreeNodeAt(index). And if there were multiple
branches open in the entire tree, we end up having multiple nodes with the SAME
index!
Can anyone give me an example of a drag-n-drop operation
entirely within a tree? The examples I have found deal with dragging datagrid
items on a tree, or dragging items from a tree to a list box. What about an
example that drags a tree item and drops on another tree item within the same
tree?
