stuff and I ain't got a clue.

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

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

List component row manipulation

I have two questions regarding as3 list component:
- I'd like to highlight and keep selected the item a user last selected from my list component. I've combed the live reference as well as google and must be typing the wrong search words. I can tell what label and index an item was that was selected but am not finding a way to highlight and keep highlighted the user's choice in the list component.
- Also, I'm exploring the notion of inline buttons within a list's rows. If a user hovers their mouse over a row, a set of small buttons come up the user can click on for further functionality. This may be more of a make your own component answer but I'm exploring it nonetheless. Any thoughts or comments on this?
Thanks!

no something else is going on. Or perhaps you didn't explain your problem clearly.
After servlet b calls getList() you have two servlets each having a reference to the same list

Adding Images to the List component

Adding Images to the List component while using the FLV
PLayback
All, ( i can send you my source files if it would help)
I'm using the FLV Playback component and loading videos into
it from an external xml file. I also have a list component tied to
the FLV playback that when you click on one of the elements in the
list, it plays that movie.
QUESTION:
My question is how do I add an image to the list component?
Below is the xml file and the actionscript. I've added the image
attribute to the XML file as img="time_square.jpg" and added the
element of the array when calling/creating the list. Did I do this
right?
Any direction would be very much appreciated.

Using a List Component to create a photo gallery.

This feels like a lot to be asking but i'm gonna go ahead and
ask to see what happens.
I'm trying to figure out how to use a list component to
select 6 items from a large list, display the words to the 6
selected items (in a text field), then finally (by pressing a
button) I would like to load the 6 corresponding pictures for the
selected items into a seperate frame. If there is anyone that could
point me in the right direction it would be greatly appreciated. I
have been trying to find information online about programming the
List Component but haven't had any luck. Is there a book that
anyone recommends that could help me? I've been doing simple
animations and websites in flash but i'm now looking to learn some
actionscripting as well. Thanks.

Hi PinkPowerRanger,
Per my understanding that you have two fields in the table "Date and Time picker" which is Date/time type and another is "Item ID", you need to get the Month from the Date field to display in the X-axis and count(Item ID) related to each
month to display in the Y-Axis, right?
I have tested on my local environment and can do this by create two calculated fields to get the month and year values from the Date/Time field.
Details information below for your reference:
Right click the main dataset to select the "Add Calculated field", specify an name of the new calculated field and add the expression in the field source as below:
Year: =Year(Fields!Date.Value)
Month: =MonthName(Month(Fields!Date.Value))
Add the three field in the Chart as below and remember in the Value area you have got the Count(ItemID) but not SUM(ItemID):
Preview you will got the chart like below:
If you still have any problem, please feel free to ask.

In Flash CS4,How can I give a AS3 List Component a suitable horizontalScrollBar

In Flash CS4 when an AS3 List Component has too many rows,it will has a verticalScrollBar automatically. but it will never has a horizontalScrollBar even a part of the content of the list is hidden.
I set the property list.horizontalScrollPolicy="on",and set list.maxHorizontalScrollPosition=200; then the horizontalScrollBar appear
but when I click the item of the list, all the list move to left, half of the list is hidden,
I can only see the right part of the list, the I click the list again,the list move to right,then I can see all the list by move the horizontalScrollBar
How can I give a suitable horizontalBar to the AS3 list component?

Thank you for your help! (sorry,I`m bad in English...)
In fact, it works.
but,I made a mistake,the reason I want to give a list a horizontalScrollBar is:I want to show all content in a list that is not wide enough,
you see,first row can show all content in this list,but in the other rows,the content is too wide to show,I want to give the list a horizontalScrollBar to show all content by draging the horizontalScrollBar to right.
now,set property:
list.horizontalScrollPolicy="on", list.maxHorizontalScrollPosition=30;(the result is the image above),when I drag the horizontalScrollBar to right:
ah ha ,the row can`t show all content too,the horizontalScrollBar is related to the width of all the list, is not related to the width of the content in every row.
now I kown why the horizontalScrollBar is always disable.
but in design,to show a lot of content,we can`t draw a list too wide, it`s not beatiful,so I want to use a horizontalScrollBar to show all content in every row.
and the list is not too wide
ah ah, like the list in Flex4
In fact,ah,I have not studied Flex 4,so,I have to make it by using Flash CS4 Component
How can I do? Please
(so sorry for my bad English,I do my best in it)

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

<![CDATA[
protected function list1_clickHandler(event:MouseEvent):void
trace(event.currentTarget.selectedIndex);

Horizontal Scroll in list component

Hi,
I'm using a list component which is populated from a textbox. I've set the horizontal scroll policy to auto and also to on however the scroll either doesn't appear (in the case of auto) or doesn't move (in the case of on). Is there a setting which I need to modify to have the horizontal scroll working normally?
Thanks

I tried the invalidate method as follows but nothing happened:
mylist.invalidate();
Not sure if I explained myself well, I just want the horizontal scrollbar to appear and be able to move it when one or more items in the list are long and thus not all visible...thanks

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!

Video, XML and List Component

Hello all,
I have this code that is suposed to take my simple little XML
file and populate it into a List component which in turn when an
item is click it will play the video assigned to it. I have a
custom player built and it works perfectly when I just load in one
movie by hard coding its path into my AS, however when I load the
XML in it only will play the first movie in the list, and will not
load in any other movie when selected.
My code is below. anyone that can help it would be greatly
appreciated. The XML code is at the bottom.

funkysoul,
First thanks for taking a look at what I have. To answer your
question yes I have changed the start up movie in the Array (i.e.
from 0 to 1 or 2 or 3) and it does play that movie first, but again
when I click to load in another movie it does not play anything
else.

Displaying items in different colors in a List component

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
