List component with suboptions

Is it possile to have a List component in Flash CS5-AS3 that has options and suboptions (and even sub-suboptions)-sort of like a vertical menu?
I've searched here in the fourm but have not found any info on this. Any sample site or tutorial?
Thanx

Sure you can do this, although it's not that straighforward. You'd need to play around with the cellRenderer property of the List component, then with this very property of the rendered item.

How can I select an item from a list component with a seperate button

This is a repost, I decided it'd probably be better here than
in the general discussion board. I will try to delete the other
one.
Hello Everyone,
This is my first post here. I am trying to figure out how to
select an item within a list component with a button. This button
is calling a function. I have searched for the past 3 hours online
and I can't find anything about it. I thought perhaps I could set
the selectedItem parameter, but that is read only, and I believe it
returns an object reference rather than something like a number so
even if i could set it, it would be pointless. I also found a get
focus button, thought that may lead me somewhere, but I think that
is for setting which component has focus currently as far as typing
in and things like that. I am lost.
Basically I am looking for a way to type this
myList.setSelected(5); where 5 is the 5th item in the list.
Any help would be much appreciated.

Never mind found it. It is the property called selectedIndex
and it is writable

Need help displaying images with List component for Flash CS4 (ActionScript 3.0)

Hi folks:
I am an inexperienced user of Flash CS4 Pro (v10.0.2). I am attempting to use the List component with ActionScript 3.0 to make a different image display when a user clicks each item in a list.
I did find a tutorial that showed me how to make different text display using a dynamic text box and the following ActionScript:
MyList.addEventListener(Event.CHANGE, ShowSelectedItem);
function ShowSelectedItem(event:Event):void {
ListText.text=MyList.selectedItem.data;
...where My List is the instance of the List component and ListText is the dynamix text box. In this case, the user clicks an item in the list, defined by the label value in the dataProvider parameter of the List component, and text displays as defined in the data value in the dataProvider parameter.
However, as I mentioned to start, what I really want to do is make images display instead of text. Can anyone provide me the steps to do this?
I appreciate your help (in advance)!!
Cindy

Hi...thanks for responding! I was planning on using images from the Library, but if there is a better way to do it, I'm open. So far, I just have text in the data property. This is part of my problem. I don't know what I need to put in the data value for an image to display. Do I just put the image file name and Flash will know to pull it from the Library? Do I need to place the images on the stage on different frames? I apologize for the "stupid user" questions, but as you can tell, I'm a newbie.
Appreciate your patience and any help you can offer!

List Component Links

I have created AS3 script for loading and parsing an RSS
feed. I have successfully displayed the "title" node on the stage
in a List Component with the instance name "blogList". Now I wish
to use the corresponding "Link" node so that each item in the list
will open a web page to the link for that story. I have been able
to get each title to link to the last URL link in the RSS feed. I
am stumped. Help :)

Answer from the boys at actionscript.org.
Works like a charm. The function for click is outside of the
function blogLoaded and most importantly used the data property on
the object in order to pass the correct reference.
var blogLoader:URLLoader = new URLLoader();
var blogURL:URLRequest = new URLRequest("
http://www.canada.com/calgaryherald/topstories.rss");
blogLoader.addEventListener(Event.COMPLETE, blogLoaded);
blogLoader.load(blogURL);
var blogXML:XML = new XML();
blogXML.ignoreWhitespace = true;
function blogLoaded(evt:Event):void {
blogXML = XML(blogLoader.data);
//trace(blogXML);
for(var item:String in blogXML.channel.item) {
blogList.addItem({label:blogXML.channel.item[item].title,data:blogXML.channel.item[item]} );
blogList.addEventListener(MouseEvent.CLICK, blogClick);
function blogClick(e:MouseEvent):void {
navigateToURL(new
URLRequest(e.currentTarget.selectedItem.data.link));

List Component multipleSelection and wmode

I'm trying to use the list component with multipleSelection
set to true; however when I set wmode to transparent in FireFox the
multiple selection breaks. It appears to function properly in IE.
Does anyone know of a workaround for this?
Thanks in advance!

"however, we need wmode set to false"
So what exactly is the problem then... if you need wmode set
to false, then don't add the param and you won't have it.

List Component - return number of item clicked

I have populated a List component with data from an XML file. I simply want the index of the line clicked returned so I can gotoAndStop to that Frame number. I have found the 'selectedItem' property but I don't want the text, I want the number of the line. Thanks.

You said you wanted the index of the line clicked, so you don't need to look further than the selectedIndex value. There is no data property for the selectedIndex value (which is merely a number);
trace(event.target.selectedIndex);
Now if your intention is to associate this with a frame number, then you have to adjust for index values starting at 0 and frame numbers starting at 1.

Width for List component

I create a List component with Strings using addItem( {
label:some_string, data:some_data } ) in a loop. I want to set the
width of the List based on the width of the widest Item. I assume
the labels must be displayed as TextFields but how do I access the
individual TextFields to get there widths?

That will depend on what layout manager you use and what you constrain the list with.

Help with a vertical scroll bar issue with a List component

hi. i have a basic <s:list> that uses an XMLListCollection as it's data provider and a very basic itemrenderer. when a row in the list is clicked a function gets the list.selectedIndex then populates some text fields with more xml data. that all works fine.. the problem i have is that the vertical scroll bar on the list seems to be "clickable" - just like a row in the list. the scroll bar scrolls normally but when it's clicked the selectedIndex becomes -1 which is not helpful b/c the value -1 is passed to the XMLListCollection.
any ideas? cheers.

thanks but still problematic...surely the <s:List> component shouldn't return a value when the scrollbar thumb is clicked? i created a very basic list (see below) and made the list dimensions short enough so that there is a vertical scrollbar and found that when the scrollbar thumb is clicked the trace(event.currentTarget.selectedIndex) returns a number. that's annoying b/c i just want a selectedIndex value for a row that is clicked not the scrollbar.
any ideas to get around? cheers

I am having a List component in my application.
I added 10 items into my list component. Now out of those 10 items, i want to disable particular list items like Item 4, Item 8, Item 9. How to do this using flash cs3 or flash 8.0.

Item10 -- Enabled state
Any suggestions/ideas would be really appreciated.

Hello Friends,
I got a partial solution for this. Now i can able to disable a particular list item using flash cs3. I achived this. But it was happening only after clicking the item values....
But i need in a diff way like, as soon as you run the flash file it has to disable. how is this possible in flash cs3.
this is the code :
    import fl.controls.List;
    import fl.controls.listClasses.CellRenderer;
    import fl.controls.listClasses.ListData;
    import fl.events.ListEvent;
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.text.TextField;
        var sampleItem1:Object = { label:"John Alpha" };
        var sampleItem2:Object = { label:"Mary Bravo" };
        var sampleItem3:Object = { label:"Trevor Gamma" };
        var sampleItem4:Object = { label:"Susan Delta" };
        var myList:List;
        var tf:TextField;
ListDataExample()
         function ListDataExample() {
            createList();
            tf = new TextField();
            tf.x = 10;
            tf.y = 125;
            addChild(tf);
         function createList():void {
            myList = new List();
            myList.move(10,10);
            myList.addItem(sampleItem1);
            myList.addItem(sampleItem2);
            myList.addItem(sampleItem3);
            myList.addItem(sampleItem4);
            myList.rowCount = 4;
            myList.addEventListener(ListEvent.ITEM_CLICK,listItemSelected);
            addChild(myList);
         function listItemSelected(e:ListEvent):void {
            var cr:CellRenderer = myList.itemToCellRenderer(e.item) as CellRenderer;
            var listData:ListData = cr.listData;
   if(cr.listData.row == 2) {
    cr.enabled = false
            tf.text = "Row selected: " + listData.row;
waiting for your replies.

How to populate list component via xml file?

There is a TextArea component that should show the name and
the description of the item selected in the list component. But I
dont know how to populate list with external XML and what should be
the coding in flash as well as what should be written in the XML.
Please help.

Here's an xml file listing a couple of brother comedy teams:
<?xml version="1.0" encoding="UTF-8"?>
<team>
<brothers>
<Marx>
<name>Groucho</name>
<name>Chico</name>
<name>Harpo</name>
<name>Zeppo</name>
<name>Gummo</name>
</Marx>
<Howard>
<name>Moe</name>
<name>Curly</name>
<name>Shemp</name>
</Howard>
</brothers>
</team>
Open a new .fla and save it in the same folder as the .xml
file. Place a List Component on the Stage and name it (in this
case, "comicTeams_list"). In the first frame write the following
ActionScript:
//create XML object and load external xml file
var broList:XML = new XML();
broList.ignoreWhite = true;
broList.onLoad = processList; // this is a function that will
be written below
broList.load("populateList.xml");
function processList(success:Boolean):Void{
if(success){
loadList();
}else{
trace("Load failure");
function loadList():Void{
var broName:String;
var listEntries =
broList.firstChild.childNodes[0].childNodes[0].childNodes.length;
for(var i:Number = 0;i<listEntries;i++){
broName =
broList.firstChild.childNodes[0].childNodes[0].childNodes
.childNodes[0].nodeValue;
trace(broName);
comicTeams_list.addItem(broName);
//to make something happen when you click on a name in the
List, create a Listener and function
var broListListener:Object = new Object();
broListListener.change = someAction; //"someAction" is a
function to be written shortly
//add the Listener to the List
comicTeams_list.addEventListener("change", broListListener);
function someAction(evtObj:Object):Void{
var pickedBrother:String = evtObj.target.selectedItem.label;
//write actions here, referencing pickedBrother variable
The names of the Marx Brothers will appear in the box.
This is written in AS2. When you post a question, it's a good
idea include which version of ActionScript you're using.

Count the rows in a list-component

Hi,
How can I count the rows with a value in a list component?
I thought it would be RowCount but as I figured out that shows the number of shown rows, not the number of rows with a value.

Hi,
Try list.dataProvider.length

Data Grid in a List Component???

Hi there!
I have a populated List Component set to Multiple Selection.
This list contains titles of a magazine issues.
I wish to allow the user to select one or more items in the
list and enter the quantity of the selected issue(s) he/she wants
to receive.
Is it possible to achieve this with a Data GRid integrated in
the List Component or which simplier solution must I contemplate?
I thank you in advance for indicating the best way to
explore.
Best regards,
Gerry

Hi GWD and thanks for responding.
I fully understood your explanations and the example you
provided.
I'll give it a try, for sure.
But I want to know:
- How do I populate a DataGrid Component? Like a List
Component? (you said they are quite the same, I assume methods to
apply are identical...)
-In the same way, I can pull out the data from a DataGrid as
I do for the List, right?
Thanks again!
Best,
gerry

I have a book with a function for quick searching arrays, but

List component trouble

Hello!
I have some trouble with the list component in my
application. The thing is that the keyboard interaction don't work
proper. I've found out that it is my function "transferParameters"
who spoils it. The function looks like this:
Object.prototype.transferParameters = function(ref)
var i;
for(i in this)
ref[ i ] = this[ i ];
I am using the function to duplicate objects without making
the instances refer to each other.
What should I do to get the keyboard interaction to work?
Regards Toben

Nope that doesn't seem to solve the problem. I tried putting
the listListener function and all the variable definitions outside
of the onData, but still have the same problem! Is there a thing
with the List component that you have to click into them before
they're activated or something? Or might it be something with
Firefox? It works almost all the time in IE.
Thanks,
Mukul
