Flash :: Reset List Component So That Nothing Is Selected
Oct 28, 2009
I have a list component on the stage in an AS3 movie. I populate it with values at runtime and the user can select multiple values. When a button is clicked I want the list to reset to a state where nothing is selected, all I can figure out is to set the selected index to 0 and have the first position on the list either blank or reading "choose from the list" and make the code ignore this if it is selected. Is there a way to reset list (and combobox components) to nothing selected.

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 can still keep the color of selected item even if it's rolled over? In my code, I have specified both the selectionColor and rollOverColor as below:
videoList.selectionColor = "0xCC0033"; //red
videoList.rollOverColor = "0xE9F3FF" //light-blue
It works well except when the selected item is rolled over. When the selected item is rolled over, it changes the color from red to light-blue. I want the selected item to stay red even when it's rolled over, but haven't found a way to achieve this.

I am working on an older Flash project created in CS3 ActionScript 2.0 How can I make the pointer cursor change to the hand when hover over a list item?_root.slidePanel.myList'myList' is the list. I have traced out the contents of the List MC and it has a child MC called 'content_mc'. I assumed this was the object containing all of my list items but the only members of this MC I can see (when tracing them out) are 'setRGB' and 'searchKey'.

Why I have to press 2 times the arrow key down to get a navigation through the list items in a list component of Flash?
Theres any workaround for this? I have a listener for keyboard event that checks if keyCode is equal to 40 if it is then I use 'stage.focus = list', but I have to press 2 times key arrow down to start navigating through list items.

I'm using the same FLVPlayback component to play many page transition videos throughout a large flash site I'm building. On each transition, I'm setting the component's source using myFLVPlayback.source and listening for the fl.video.VideoEvent.READY event before proceeding with each page transition. This works fine as long as the transition between every pair of pages uses a different video.
Unfortunately, I'm running into a problem when the same page-to-page transition video needs to get invoked for two consecutive transitions. When playing the same video twice in a row, setting the source property of the component to the value it already has doesn't seem to do anything, meaning that my listeners for fl.video.VideoEvent.READY never fire. I could do something hackish like setting the source to a tiny, never-used-elsewhere FLV before setting it to the FLV that I'm actually using for the transition as a means of "resetting" the component, but I'd like to know what best practices are in a situation like this (insofar as best practices with something like the FLVPlaybackComponent can be discussed with a straight face).
I've perused the livedocs for the component but came up empty-handed, and manually using NetStream, NetConnection, and Video objects at this late stage isn't really an option.

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?

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

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 have two Lists (components) on stage. The first one (mainList populates from an XML called topics.xml
[Code]...
on event handler change, I want to load the second list on the other list component, called subList..It's not loading.. I believe it's because when it reads the data from my topics list, it reads topic1.xml instead of "topic1.xml" ( reads without the quotes). If I unquote line v.list.load("subtopic.xml"), it works, but I need it to be loaded from the XML..

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 component which I use to display a list of songs in a music application. Next to each item in the list I need to add a little mp3 player. The mp3 player has a preloader to show the mp3 is loading, then a play/stop toggle button. Does anyone know how to use the cellrender to add this mp3 player to each item in a Flash List component?

Because of screen size, I must ensure we're only displaying necessary data to the user.I have a drop down box that contains only 5 items and I would like that when an item is selected, it doesn't appear in the drop down box (since technically it's showing twice, once at the top as the selected item and once in the list). how I would achieve this? I tried using a custom CellRender and overriding the "set selected" function to call this.visible = false if selected is true, but that simply hides the item but does not remove it from the layout of the drop down list.

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
