RE: [flexcoders] e4x, nested elements & tree data provider

[Tracy Spratt]

XML works fine with tree.  The xml methods dispatch the necessary events
to sync the display with the xml changes.

Not sure what you're really asking, how to do a nested tree? You need to
use XMLList instead of XML (I don't think it dynamically casts the
dataProvider to a XMLList if you provide it just XML).

 

You can swap out label with name and use the same labelField convention.

 

good luck,

Here's a tested example:

 

<mx:XMLList id="myTreeData">

            <node label="Accounts">

                <node label="First Account">

                    <node label="Inbox">

                        <node label="Flexcoders"/>

                        <node label="Flashcoders"/>

                        <node label="Flashnewbie"/>

                    </node>

                    <node label="Send Items">

                        <node label="Nested Tree e4x"/>

                    </node>

                    <node label="Trash">

                        <node label="Flashnewbie"/>

                    </node>

                        </node>            

                <node label="Second Account">

                    <node label="Inbox">

                        <node label="New Messages"/>

                        <node label="Flagged Items"/>

                        <node label="Attachments"/>

                        <node label="All Mail"/>

                    </node>

                    <node label="Send Items">

                        <node label="Tree Data Provider with e4x"/>

                    </node>

                    <node label="Trash">

                        <node label="Lame Yahoo HTML emails"/>

                    </node>

                        </node>            

       </node>            

</mx:XMLList>

I'm whipping up a mock-up of a UI much like a mail client (folder tree
+ data grid), using XML dummy data. I've got the rows of the data grid
populating with an e4x predicate, and I have the tree populating with
data like this:

<mx:Tree x="0" y="0" width="100%" height="100%"
dataProvider="{folders}" labelField="@name" showRoot="false"
defaultLeafIcon="@Embed(source='Assets.swf',
symbol='TreeFolderClosed')"></mx:Tree>

<mx:XML id="folders">
<folders>
<account name="account1">
<folder name="Inbox">
</folder>
<folder name="Sent Items">
</folder>
</account>
<account name="account2">
<folder name="Inbox">
</folder>
<folder name="Sent Items">
</folder>
