Yeah, this blog isn’t very friendly for posting code. You’d need to escape your < as &lt; before posting.

As for your ComboBox question, set the prompt property. For an example, see “Creating a simple label function on a Flex ComboBox control”.

i did some work and find out some things, and realised what u meant.I used “isBranch=”true”" in tree XML and it seems that that did the trick. I got this XML now:

my tree looks like this:

i used your function tree_labelFunc:
private function tree_labelFunc(item:XML):String {
var label:String = item.@label;
if (tree1.dataDescriptor.hasChildren(item)) {selectednode.text = label;
comboBoxFolder[j] = label;
label += ” (” + tree1.dataDescriptor.getChildren(item).length + “)”;
}
return label;
}
Tree is now just like i wanted. Only one thing i need now, its about combobox, im using this:

private function comboBox_labelFunc(item:XML):String {return item.@label;}

this works fine since i dont have any leafs in root of the tree, and i wont have them.
now, the thing i need is, when i start application selected item in combobox is first item in combobox, in this case its “news”, how do i set that when application starts noone of the items are selected.

Dusan.

Sorry, I guess I’m confused. It seems you’re trying to display possibly nested data in a linear List. How would you know if a node is an empty branch or just a leaf node?
The isBranch() method works on a Tree because Trees can have multiple levels with children, whereas a list is usually only for displaying flat data.

If you only want to display the “i) four (4)” and “ii) three (2)” branches, I think you’d need to use the following E4X which grabs all branches with at least one child:

dataProvider="{treeDP..node.(children().length() != 0)}"

Otherwise, how would your Flex application know if it was looking at an empty branch or a leaf node (unless you put some sort of flag in your XML nodes indicating whether something was a branch or leaf).

Something like this?

<mx:ComboBox id="checkBox"
        dataProvider="{treeDP..node}"
        labelFunction="comboBox_labelFunc" />

Peter

ty a lot for help so far

Something like this?

<mx:XML id="treeDP">
    <root>
        <node label="i) One" />
        <node label="i) Two" />
        <node label="i) Three" />
        <node label="i) Four">
            <node label="ii) One" />
            <node label="ii) Two" />
            <node label="ii) Three">
                <node label="iii) One" />
                <node label="iii) Two" />
            </node>
            <node label="ii) Four" />
        </node>
        <node label="i) Five" />
        <node label="i) Six" />
    </root>
</mx:XML>

<mx:ComboBox id="checkBox"
        dataProvider="{treeDP..node.(children().length() != 0)}"
        labelFunction="comboBox_labelFunc" />

<mx:Script>
    <![CDATA[
        private function comboBox_labelFunc(item:XML):String {
            var numChildren:int = item.children().length();
            var suffix:String = "";
            if (numChildren != 0) {
                suffix = " (" + numChildren + ")";
            }
            return item.@label + suffix;
        }
    ]]>
</mx:Script>
