Flex :: Access Items Selected In A Component From The Main App?
Sep 11, 2010
How can I Access Items Selected in a Component from the Main App I've got a component that has a listControl and a couple of RadioButtonGroups. I need to access the selected items in the main application. What's the best/simplest way to create and access the array of selected items. So, the user clicks the button to confirm the selections and then I need to access those selections in the main app. Is there a way I can use a public var to build the array? Another idea?
<mx:Tile direction="horizontal">
<mx:Box>
<mx:Label text="Year" fontWeight="bold"/>
<mx:List id="myYear" >

I am learning Adobe Air and want to get the current selected item in the spinner list I have created, however every time I use selectedItem I keep getting the same value over and over, no matter what option I select. I am trying to make an application for the Playbook and this this my SpinnerList code:
<s:SpinnerListContainer x="10" y="279" width="325" height="266">
<s:SpinnerList width="69" height="100%" enabled="true" labelField="data" selectedIndex="1" id="From">

I'm having troubles getting selectedItems from a List Component in Flash CS4. Each time I select multiple selections the object that selectedItems returns seems to be populated with the last selected item in each of its instances. What is strange from the example I provide below is that once you've made your selection and click the label you can update another list with the correct selected values. But the output values are still traced incorrectly.
Code:
import fl.data.DataProvider;
import fl.controls.List;
import fl.controls.Button;
var dp:DataProvider = new DataProvider();
dp.addItem({label:"Item 1"});

I would like to use the selectionMode=multiple described in the Flex docs, but with a few modifications:
1) I would like the box that the user drags over the graph to remain there until the user drags a new one.
2) In the top right corner of the box I want to display the sum of the items selected by that box.

End-User searches for something and an ArrayCollection is returned with Result objects. This is displayed in a data grid.End-User selects a few of the search results and "moves" it over to another datagrid for use later.End-User does another search.
PROBLEM:Some of the search results might contain something the user already previously selected and moved over to the second datagrid. I want to remove these from the second search result.

It uses a focus_out event to detect if there is a change that needs to be committed. However I notice that a FOCUS_OUT event is only called if you click away from the textfield but inside the component. Is there any way I can listen for clicks outside the component from within the component?
addEventListener(FocusEvent.FOCUS_OUT, onFocusOut);
protected function onFocusOut(event:FocusEvent):void

I have a TileList with thumbnail images. Under each thumbnail images I display the name of the image. I want to build rename functionality. So under the TileList is a "Rename selected image" button.
When this button is clicked, I would like to change the state of the itemRenderer component. The label underneath the image will change into a TextInput so that the user can type a new name. This is much like the Windows rename file functionality.
How can I access the itemRenderer of the selected image? How can I make it happen that it listens to the click event of the Rename button?[code]...

I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

I have a List of items which is based on the contents of the "category" that a user selects
When the user changes selection, I change the dataProvider of the list be be the contents of the current category.
Sometimes the list contains items, sometimes it does not
Is there a way of hiding the list when it has no items?
I know that I could do this when setting the dataProvider, but it seems like there should be an event or something else that I could be using.

I have an app where a user puts in the required info into text inputs inside a titlewindow pop up and it sends the data entered into a datagrid. This first time when I call for the popup and enter info it works fine. Here's the problem: the next time I call the component pop up and click anywhere on the popup, including textInputs, the first the item in the array is automatically entered into the textInput where the user is supposed to enter the data themselves (BTW this textInput is also a autocomplete component).What I want is nothing to entered into textinput until the user inputs the data themselves. I've been tweaking with it for hours and im stumped. Here's the code: (this is main page)

When I set style color, it changes both the text color for the selected item/component label and the text in the dropdown menu.
color
Type: uint Format: Color CSS Inheritance: yes
Color of text in the component, including the component label. The default value is 0x0B333C.
I would really like the label to be white and the text to be black.

I have a component with a public variable declared
[Bindable]
public var mnuSource:String;
When I extend this component, I can reference mnuSource (it compiles) but Runtime complains about the property not being accessible (error 1056).
How do you modify / declare component properties so they are actually available to other components?

In one area of my application I am creating a display that builds itself with actionscript during a loop. (in my actual app there are A LOT of nested children and my function might be looking for any of those children) In that AS I assign each item an ID, but when I try to access that item by it's id it fails. What gives? and how can I accomplish finding a UI component without having to go through knowing all of it's possible parents? [code]

ok so i know the general code to rename all selected library items
var items = fl.getDocumentDOM().library.getSelectedItems();
for (var i=0; i<items.length; i++){
var item = items[i];
item.name = "ABC_"+item.name;
}
but this isn't good enough if the library items are in folders... because item.name returns the full path, but item.name sets the name. o.O as someone else points out here, [URL]
so when i try to rename Level1 to be ABC_Level1 if Level1's folder path is LIBRARY/FolderA/FolderB/Level1 i get this instead ABC_FolderA-FolderB-Level1
i could probably code some sort of string parser something like this,
item.name = "ABC_"+item.name.substr(item.name.lastIndexOf("-"), 99)
but that is really ugly and would not work if library items contained "-" already. "Level-1" for example
different way to access the name that returns just the name and not the path

I have a Listbox whith a ArrayCollection as datasource. I'm trying to remove the selected items from the ArrayCollection to update the list.Here is how I coded the remove function:
for each (var item:Item in theList.selectedItems)
{
theArrayCollection.removeItemAt(theArrayCollection .getItemIndex(item));
}
This works fine as long as the ArrayCollection is not sorted. When I apply a sort I get a RangeError from ListCollectionView.removeItemAt.
