How to access spark list selected items

selected items is some sort of vector? I can't access the items in it, can anyone shed some light on how to acess them? Maybe print them to the screen?

I too am dragging through the documentation with a fine toothed comb and am at a loss of how to get something as simple (and intiutive) as myList.items.
Maybe I'm overthinking it, but if I have a custom item renderer with a checkbox in it and when the user clicks the checkbox and it's selected state changes, I'd like to let the List that contains the List Item know of it... not that the item was messed with, but more to the point, that the checkbox was messed with and which item it was a member of...
Right now I can't even figure out how to do something as rediculously simple as creating a creationComplete handler that iterates through the list items and calls a function in them to set a reference to itself that the list item can reference.

How do i set spark list selected item's color??

hey guys... so got a little problem... i have a spark list which gets populated from a array collection that looks likda like this
[0] = "name1"
[1] = "name 2"
[2] = "name 3"
when i click on say "name 1" i need the color of "name 1" to change to say red...
and when i click on another item i need that color to stay... red on "name 1"...
oh and... i need to do the color change in actionscript rather than the mxml file...
any ideas???

Hi,
I'm not sure if this is exactly what you are looking for. What I did was created an itemRender for the list and assigned it like so
<s:List dataProvider="{ listDataProvider}" itemRenderer="listItemRenderer"/>
And the listItemRenderer will look some
//Code Begins
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
                          xmlns:s="library://ns.adobe.com/flex/spark"
                          xmlns:mx="library://ns.adobe.com/flex/mx"
                          focusEnabled="true" >
    <fx:Script>
        <![CDATA[
            var clicked:Boolean=true;
            protected function clickHandler(event:MouseEvent):void
                    clicked?labelRender.setStyle("color","0x00FF00"):labelRender.setStyle("color","0xFF0000") ;
                    clicked=!clicked;
        ]]>
    </fx:Script>
    <s:Label id="labelRender" text="{data}" color="0xFF0000" click="clickHandler(event)"/>
</s:ItemRenderer>
//Code Ends
In the above example the colour toggles on each click. So, you can apply anything. assume you have a property called color in your array collection, you can access it as data.color and then set the text to that color when it is clicked. I hope this helps. Do write back if you have any issues.

Disable Spark List selection indicator

How do I get rid of the Spark List selection indicator entirely? I don't want the rectangular indicator when the mouse hovers over an item, and I don't want the color to change when the mouse is clicked.

You'll have to extend default item renderer (ItemRenderer for instance) and set autoDrawBackground to false. And then use your item renderer in a list.
See this document for more information on spark item renderers.

How to edit the list box items in labwindow/CVI?

how to edit the list box items in labwindow/CVI?

Listbox items cannot be edited directly in the control: what you can do is to select a line an, transfer its content to a textbox control, edit text there and move text back to the listbox control. Available interactions with the listbox control are listed in the help.
An alternative to it is to use a tree customized to appear like a listbox: tree item labels can be edited directly in the control, at least those in the base column of the tree. You can look at the example \samples\userint\treelist.cws that shows how a tree can be customized this way. I haven't opened it, but this old example too should show the ability to edit tree cells.
Proud to use LW/CVI from 3.1 on.

How to make a listbox selected item highlight color from code the same as if user click on item?

Hi all,
I have a listbox that gets filled with data when my program starts. I save the last selectedItem value so I set it when the program start again. But the color that the selected item has is not the same as if the user click on it (pictures below).
The color when I set the selectedIndex=someItem is black on light grey (background)
The color when the user clicks on the item is white on blue (background)
Any way to make them both white on blue (background)?
Thanks
This is the user clicking on it:
This is the code:

I think the difference is focus. When you use the mouse to select it also sets focus to the listbox so you would have to set focus to the listbox when you set the selected item. How are you setting your selected item? I think that by
using a property to hold the selected item rather than setting the index that might also fix the problem.

Accessing S:List Checkbox Item Renderer Outside the Renderer

Hi All,
I have an S:List, with a checkbox item renderer. I was to be able to access the selected portion of the renderer to create a new function that at the press of a button this will delect all the current selected items in the list.
Doco states that i should be able to do this just by setting the selectedIndex to -1. But not sure if this is specific to 4.5?? But it is not working for me.
Below is my current list. Outside of this list flashbuilder does not know about chkList, or even selected. How can i get access to this to deslect all?
<s:List
id="ltattributes">
<s:itemRenderer>
<fx:Component>
<s:ItemRenderer>
<fx:Script>
<![CDATA[
import mx.events.ItemClickEvent;
protected function chkList_changeHandler(event:Event):void
var e:ItemClickEvent = new ItemClickEvent(ItemClickEvent.ITEM_CLICK, true);
data.selected = event.currentTarget.selected;
e.item = data;
e.index = itemIndex;
dispatchEvent(e);
]]>
</fx:Script>
<s:CheckBox id="chkList" selected="false" label="{data.displayname}" change="chkList_changeHandler(event)"/>
</s:ItemRenderer>
</fx:Component>
</s:itemRenderer>
Thanks

Try: dataGroup.getElementAt().

Getting a lists selected item itemRenderer's properties

Is there a way to get a Spark List's selectedItem itemRenderer's contentToGlobal x and y and it's height values?
Thanks,
John

Hello Shongrunden;
Thanks again for your help, if you don't mind me asking a couple of more questions...
- With a scrollable Spark List, if a selected item is partially in view, is there a method to get just the visible height of the itemRenderer?
- Also, on my custom paged List component, with a custom itemRenderer and useVirtualLayout = true, after the list data is retrieved a resultHandler is called, in this I then call your getRendererCoordinates function. I also call getRendererCoordinates() in a listChangeHandler.
After the resultHandler calls getRendererCoordinates, even though the dataGroup is showing the proper number of elements, and I set the list.selectedIndex to 0, the renderer variable created in;
var renderer:IVisualElement = list.dataGroup.getElementAt(list.selectedIndex);
the renderer var returns null on the initial display called from the resultHandler, but ... it works perfect on on the listChangeHandler and subsequent page displays. So it seems the renderer is not finished being drawn when getRendererCoordinates is being called from the resultHandler, but subsequent page displays work probably because the renderer has already been drawn. I've tried callLater(getRendererCoordinates) but since nothing else is going on it won't trigger. I did not see an event that can be dispatched from IVisualElement after it is completely drawn that I can use to call getRendererCoordinates.
Any suggestions?
Thanks again for your help and time,
John

How i can set the selected item of a dropDown component from java code

Hi
Thank you for reading my post
How i can set the slected item of a DropDown component from backing beans java code ?
it is binded with a database , so one field determine its display and one other field determine its value , I want to set the selected item of this combobox
In back code i have both value and display values to use them .
can some one give me some help ?
Thanks ,

See code sample 3 at http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/helloweb.html
See also, the selection components row in the table under http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/helloweb.html
It says
One way to preselect items is to call setSelectedValue(Object[]) or setSelectedValue(Object) from the prerender() method. You pass in the return values of the items that you want preselected. Be sure to verify that getSelected() returns null before setting the default options, or you will overwrite the user's selections on a post-back.

How to disable a lead selected item in a radio button group ?

Hi,
I have a radio button group and there are entries to create radio buttons dynamically. means there is only one radio button group in the UI design and in runtime I will be having two radio buttons (For ex: Yes and No ) . Now If I want to disable either Yes or No radio button, I am unable to do so. because If I disable the radio button group it disables both. So, I can have lead selected item for ex: Yes which I want to disable. I want to know specifically how this Yes button to be disabled by taking lead selected index item.
Please help.
Thanks

Try setting the radio button value of the lead selected button to abap_false/space.

Spark List Itemrenderer items outside of List

I have a spark list and i want some of the items in it to appear out side of the list depending on the users interaction.
Is there a way to make items of an item renderer appear outsid of the LIst container?
When i use basic layout on the lsit and explicitly set the x and y, they appear behind the list.
Thanks.

Hi jmandawg,
My ListRenderer.mxml may be what you want as follows,
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer
xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="
library://ns.adobe.com/flex/spark" xmlns:mx="
library://ns.adobe.com/flex/mx" hide="mOut(
null)" mouseMove="mOut(event)" mouseOut="mOutValueItem(event)"mouseDownOutside="mOut(event)" creationComplete="inited()"
autoDrawBackground="
true">
<fx:Script>
<![CDATA[
import mx.controls.TextInput;
import mx.managers.PopUpManager;
import mx.utils.StringUtil;
import flash.text.TextLineMetrics;
public var mouseOnPopup:Boolean = false;
public var vi:mx.controls.TextInput;
private function inited():void {vi =
new mx.controls.TextInput();vi.editable=
false;vi.addEventListener(MouseEvent.MOUSE_OUT, mOut);
vi.addEventListener(MouseEvent.ROLL_OUT, mOut);
vi.addEventListener(MouseEvent.MOUSE_OVER, mOverPopup);
private function mOut(event:MouseEvent):void {
if ( vi.isPopUp ) {PopUpManager.removePopUp(vi)
mouseOnPopup =
false;}
private function mOverPopup(event:MouseEvent):void {mouseOnPopup =
true;}
private function mOutValueItem(event:MouseEvent):void {
if ( vi.isPopUp && !mouseOnPopup) {PopUpManager.removePopUp(vi)
private function mOver(event:MouseEvent):void {
var txt:String = itemValue.texttxt = StringUtil.trim(txt);
if(txt.length<5) return;
if(!vi.isPopUp) {PopUpManager.addPopUp(vi,
this.parent)vi.text=txt;
vi.setStyle(
'fontSize',18);
var txtMetrics:TextLineMetrics = vi.measureText(vi.text);vi.width=txtMetrics.width*1.2
vi.height=itemValue.height*1.4
var p:Point = itemValue.localToGlobal(new Point(itemValue.x, itemValue.y));vi.x=p.x;
vi.y=p.y-10;
]]>
</fx:Script>
<s:TextInput id="itemValue" text="{data.value}" width="200" mouseOver="mOver(event)" mouseOut="mOutValueItem(event)" mouseMove="mOut(event)" editable="false"/>
</s:ItemRenderer>
You may test it with the following in your main.mxml
Bindable]
private var detailAC:ArrayCollection = new ArrayCollection([{value:"nteDevice.device"},{value:
"nteDevice.deviceTypenteDevice.loopbackIpAddr"},{value:
"nteDevice.ipAddressnteDevice.loopbackIpAddr"},{value:
"nteDevice.loopbackIpAddrnteDevice.loopbackIpAddr"}, {value:
"nteDevice.release"},{value:
"nteDevice.releasenteDevice.loopbackIpAddr"},{value:
"nteDevice.clli"},{value:
"nteDevice.provisionStatus"}]);
<s:List id="lst" itemRenderer="com.att.ntscp.view.component.ListRenderer" dataProvider="{detailAC}" width="200" height="200"/>
Is it a little bit trick?

How to access Sharepoint List using a Different user. Access SharePoint List using some Authentication

Hi,
SharePoint version 2010
I am building an application in Java and would want to accesss a SharePoint List through REST. I have been trying to find out how the authentication process would work once i want to deploy it into Production.
I am not able to find anything useful to send user detail / authentication. Can you please help me out here.
Thanks,
Bhaskar.
Thanks, Bhaskar

Hi,
According to your post, my understanding is that you want to access SharePoint list from Java application through REST.
In some cases you may need to create a new access token (this is somewhat akin to "running as a different user").
Essentially, you are using a different user's security context. Typically, you would create an Active Directory account specifically for this purpose and then grant appropriate rights to the user account in SharePoint.

How to change images of selected items in gridview on selection changed event in universal app

Hi,
I am developing Universal App. I have bind the images to the Gridview using ObservableCollection. I have set gridview
SelectionMode as Multiple . I want to change the images of selected items but I don't know how to do in Selection Changed event of Gridview. I got selected items with the help of
Gridview SelectedItems property. How can i change the images of respected selected items?
Please reply me asap.
Thanks in advance.

Hi, Sorry for late reply,
Please change the class :
public class ImageCollection : INotifyPropertyChanged
private string source;
public string Source
get { return source; }
set { SetProperty(ref source, value); }
public int MyProperty { get; set; }
protected void SetProperty<T>(ref T storage, T value, [System.Runtime.CompilerServices.CallerMemberName] String propertyName = null)
if (!object.Equals(storage, value))
storage = value;
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
protected void RaisePropertyChanged([System.Runtime.CompilerServices.CallerMemberName] String propertyName = null)
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
public event PropertyChangedEventHandler PropertyChanged;
XAML
<GridView x:Name="gd"

img.Add(new ImageCollection() { MyProperty = 2, Source = "ms-appx:///Assets/2.jpg" });
img.Add(new ImageCollection() { MyProperty = 3, Source = "ms-appx:///Assets/3.jpg" });
img.Add(new ImageCollection() { MyProperty = 4, Source = "ms-appx:///Assets/4.jpeg" });
gd.ItemsSource = img;
private void gd_Tapped(object sender, TappedRoutedEventArgs e)
GridView gv = (GridView)sender;
ImageCollection ic = gv.SelectedItem as ImageCollection;
ic.Source = "ms-appx:///Assets/4.jpeg";
gv.UpdateLayout();
I have used INotifyPropertyChanged now UI is not fluctuate
and I have not bind again O-Collection.
I hope so You will get right answer.
