Flash Tree Object & node list

Question

Hi All,
Unsure if this is a noodle scratcher or undoable!
Either way, does anyone know of a way when using the 'tree'
flash component in Director to get the component to supply a list
of some sort back to director.
I'm adding & subtracting branches to the Object
successfully, but I figure it must know whats where I just need it
to tell Director so I can manipulate it out to a XML file !!
Cheers

Alright, this is a long one. Make a Director file based on
the following and when it starts it’ll open the xmlDoc.xml
XML file, parse it into a Flash XML object and assign that object
as the dataProvider for a Flash component Tree. Then you can select
a planet node from the Tree, enter text into the Flash component
text field, and click the Flash button to add a moon to the
selected planet node with the entered text as its label. The button
also saves whatever XML makes up the tree to the xmlDoc.xml XML
file by calling the saveXml() function. You could have whatever
event you want call the save function.
To start, drag a Flash Tree component to the stage as sprite
1, a Flash TextInput component to the stage as sprite 2 and a Flash
Button component to the stage as sprite 3. Make sure to do
Modify>Movie>Xtras… and add the FileIo.x32 Xtra so
it’ll work if you make a projector.
Add this script to Frame one:
function exitFrame(me)
///// make Fileio obj, Flash XML obj, populate Tree
// Fileio
var fileObj = new xtra("fileio");
fileObj.openFile(_movie.path + "xmlDoc.xml",0);
var xmlString = fileObj.readFile();
fileObj.closeFile();
fileObj = null;
// Flash XML obj
var fTree = sprite(1);
var fXmlObj = fTree.newObject("XML");
fXmlObj.ignoreWhite = true;
fXmlObj.parseXML(xmlString);
// populate Tree
fTree.dataProvider = fXmlObj;
///// make button listerner to handle clicks
var fButton = sprite(3);
var fButtonEvt = fButton.newObject("Object");
fButton.addEventListener("click",fButtonEvt);
fButton.setCallback(fButton, "click",
symbol("fButtonClick"), "fButtonEvtScript");
Make this Movie Script, name it fButtonEvtScript:
function fButtonClick(me,evtObj)
var fTree = sprite(1);
var fText = sprite(2);
// determine if a Tree node is selected
try
String(fTree.selectedNode.attributes.label);
// execute if node selected is planet
if (fTree.selectedNode.nodeName == "planet")
var newNode = fTree.newObject("XMLNode",1,"moon");
// make node lable text field if text present, else default
text
if (fText.text == "")
newNode.attributes.label = "Default Moon";
} else {
newNode.attributes.label = fText.text;
// add new moon node
fTree.selectedNode.addTreeNode(newNode);
saveXml();
} else {
_player.alert("Must select planet node");
} catch (errObj) {
// alert no node
_player.alert("No Node Selected");
function saveXml()
var fTree = sprite(1);
// make string to save
var xmlString = "<?xml version=\"1.0\"
encoding=\"iso-8859-1\" ?>\n"
xmlString += fTree.dataProvider.firstChild.toString();
// save file
var fileObj = new xtra("fileio");
fileObj.openFile(_movie.path + "xmlDoc.xml",0);
fileObj["delete"].call(fileObj);
fileObj.createFile(_movie.path + "xmlDoc.xml");
fileObj.openFile(_movie.path + "xmlDoc.xml",0);
fileObj.writeString(xmlString);
fileObj.closeFile();
fileObj = null;
Finaly add this script to any Frame after Frame one; I used
Frame 10.
function exitFrame(me)
_movie.go(_movie.frame);
Here’s the XML file:
<?xml version="1.0" encoding="iso-8859-1" ?>
<star label="Sol">
<planet label="Mercury" />
<planet label="Venus" />
<planet label="Terra">
<moon label="Luna" />
</planet>
<planet label="Mars">
<moon label="Phobos" />
<moon label="Deimos" />
</planet>
<planet label="Jupiter">
<moon label="Callisto" />
<moon label="Ganymede" />
<moon label="Europa" />
<moon label="Io" />
</planet>
<planet label="Saturn">
<moon label="Titan" />
</planet>
<planet label="Uranus" />
<planet label="Neptune" />
<planet label="Pluto">
<moon label="Charon" />
</planet>
</star>
Sorry I got slack with the code comments, but I reckon you
can figure out what’s going on. I figure this’ll give
you a good start on what you’re trying to accomplish. I
strongly suggest checking out the LiveDocs for Director regarding
Flash and Components and Flash regarding Flash XML, XMLNode and the
Components Language Reference. Remember though, things have changed
since the Flash 8 Asset Xtra, so some of the documentation is out
of date.
