Flex :: Access Selected Items In Adobe Air Using The Spinner List?
Feb 21, 2012
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:
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?

In Flex 4 (beta 2), I have a list control populated from an XMLListCollection. What I would like to do is when an item is selected in the list, use a custom item renderer on the selected item as well as the item that appears just prior to the selected item in the list.
I am using a spark list control, but I am open to alternate components if the solution makes sense.Here is the strucutre of the xml used to populate the XMLListCollection
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.
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"}); [Code] .....
I have placed TextFileds inside TileList Compontent. When i try to select the TextField it can't show the selected Textfield in the TileList items by default the TileList items are selected.Finally i need to select the TextFields.
Here is my code:
import fl.controls.TileList; import fl.data.DataProvider; import flash.display.Sprite; import flash.events.Event; function TileListExample() { var dp:DataProvider = new DataProvider(); var totalEntries:uint = 3; var i:uint; for(i=0; i<totalEntries; i++) { dp.addItem( { source:getTf(), scaleContent:false}
I'm creating a facebook application in flex. I'm actually working on the friends component that shows your friends who are using the application. now, each friend has a profile image.
I created the component using a s:List element.
In the Skin Class of the element i configured the requestedColumnCount to 3, which means it shows 3 friends. i added buttons to scroll left and right in the list.
Whenever I scroll to see a different friend, for a half of a second i see no image because the List component is loading the image in order to view it.
is there a way to make the list preload all the elements so i won't have this kind of problem ?
I'm using flex 4.1 to write an application. i read in the documents that has the rowCount property to set how many items to display. the does not have that property. how can I limit the list to display 3 items ?
The 'recommendations' dataProvider is an ArrayCollection of String, which are generally sentences about as long as this one. By setting the variableRowHeight and wordWrap properties as shown, if a sentence is too long to fit on a single line, everything works fine- the row expands and the messages show on two lines, or occasionally three.
The space allocated for this panel within the entire canvas means if the total text size of 'recommendations' exceeds six lines, I need for the entire list scroll. This is also working just fine. The trouble is when using the mouse wheel to do the scrolling- Flex scrolls both the entire list and the single item where the mouse is hovering. Often this results in only the second half of a sentence being visible. Non-programmer friends I have asked to look at this noticed this, and tell me it as a problem. If a user does not notice the dual scrolling, and sees only a fragment of a sentence, it will be perceived as an error in the application.
I have 2 comboboxes which are dependent (country and state) and one submit button. Now what i want is after user submits the form it should display one alert box which should be like
selected country is "selected item" selected state is"selected item"
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.
Does anyone know of a component or tutorial for implementing a slot machine-like list similar to the interface component on the iPhone (example at URL...)? I did find one commercial component for flex at URL..., but am not sure how open this would be for modification (looks like it's a compiled SWC file in the example).
I have a spark list, which is based on a dataProvider. As the application runs, the data in the dataprovider can change, and also the dataProvider can be swapped for a different one
What I need to do is make sure that something is always selected in the list (unless it is empty)
I'm having a problem with getting the value of an item that the user selects in my mobile Flex application. When I select an item from the list I place that item into an ArrayCollection. But when I check the value (trace()), the value is [object Object] and I can't seem to access the actual value of the object. Here is what I am doing:
private var selectedPlayers:ArrayCollection = new ArrayCollection(); private var numOfPlayers:int; ... //check if item is not already in selected players list
When a combobox is elected in the flex app, there is a quick flicker, then the combobox needs to be selected again in order to get the dropdown to open. After that, the dropdown works as expected, but only while selecting the control subsequent times while on the form. Reloading the form requires the double selection again.
I have a list with custom item renderers. What I would like is when one of the list items is selected to position another control OUTSIDE the list to the same vertical position as the selected item.
I'm setting selected element in s:List component with Actionscript, it works, but List doesn't scroll to selected item -- need to scroll with scrollbar or mouse. Is it possible to auto-scroll to selected item
I have a Flex list and a custom ItemRenderer. I'd like to be able to have some items in the list use a different ItemRenderer (say, depending on the class of the item). Is this possible?
I am editing an old (2006) Flash file that was left over from a previous designer. He used AS 3. I noticed that old and new AS (F9) panels are different. I've looked everywhere in the new version to find the timeline functions that you can just double click on to add to the AS panel [see image] but can't find them.
Is it possible to still access these "easy to use" older list of AS items in the new AS panel?
No matter what I do, these buttons have a vertical gap inbetween them. I have tried everything from setting the "vertical-gap" property to negative and positive numbers as well as changing the padding-bottom and padding-top on them. I want the buttons to be right up against eachother vertically. I have also tried "button-height" and padding on the List component...still nothing. How do I control this?
