ActionScript 3.0 :: Accessing List Component Skins?
May 28, 2010
unable to figure out how you can access a List Component Skins using ActionScript. What I'm trying to do is access the CellRenderedSelectedUp skin and:
1. Change it's color using ActionScript
2. Make it change its' color when that list item is clicked
So, let's say that the first item in the List is clicked. I want ActionScript to override the default coloring of the Selected Up skin (say change the color to yellow) and stay that color(yellow) until another list item is clicked on.

Objective:I would like to pass Skins to an itemRenderer (which is a Button) of a List, and be able to skin every button in that List.This is what I have:
List:
<s:List itemRenderer="renderers.ItemRenderer" dataProvider="{collectionWorkspace}" />
ArrayCollection:
<s:ArrayCollection id="collectionWorkspace">
<comp:Layout1 />[code]...
I get an error (fixed for clarification):Error: Skin for Application....Button1 cannot be found.

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'.

I have a combobox and list component on the stage. The combobox has 3 selections. How do I get it so that each selection triggers the specific xml file to load into the list component? I can't get them to communicate to each other.

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 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 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..

I have a stage with instances of bauble_mcs on it that are attached by the document class of the main timeline (can someone tell me what the right term is here? I don't know what I call the main time line in AS3).
I then have instances of snow_mc attached by the same class. Inside the snow_mc I want to test to see if it is hitting any bauble_mcs but I don't know how!

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 movie clip on my scene with a number of objects all prefixed with a keyword 'build' (e.g. 'build8934', 'build4920') - is there any method, array or object that I can access that would give me access to a list of objects for that movie clip?I'm intending to loop through an add events to an instance which matches the prefix 'build' and set additional properties based off that instance.x.

I need to access a non-display list top-level (Parent? Ancestor? What's the correct term?) object from a display list object, and I don't know how.
In my code, ResultX is an instance of my custom class Result. Card is a sprite, a visual representation of the ResultX object, defined inside the Result class and attached (or removed) to the stage via a separate function inside the result class as needed.
I want to refer to the correct Result object when the user clicks on the corresponding card to call a function there. In accessing the sprite manually, ResultX.card works fine, but I don't know how to go upwards trough the path - card.parent (or actually target.parent, since it's done via event) just returns Main, of course.

I have a two components Test_Interface.mxml & teacher_fullscreen.mxml. I called teacher_fullscreen.mxml from Test_Interface.mxml by
[Code]...
Now I created an instance of Test_interface in my 2nd mxml by
Code: public var par:Test_Interface=new Test_Interface(); Actually, I wanted to disable a button in Test_interaface.mxml with id = "b1" from my 2nd mxml using the object created above. So I gave par.b1.enabled=false; It did not give any compile errors but during run time cannot access object or method of null reference sandbox error was returned for the statement par.b1.enabled=false. So how do I change the property of a button in one component from other.

I currently have a list that I'm using to hold text so when an item in the list is selected the text is displayed in a text box along side it. I want to have the first item in the list to be pre-selected so the text for that item is already in the textbox when it is loaded.

(Actionscript 2 btw - and actually cs4, not that it really makes any difference?) I have a class that instantiates a movieclip from the library, e.g.:
Code:
debugbar:MovieClip = thing.AttachMovie("debugbar", "debugbar_mc", 999);
So attaching it to the where ever "thing" is - could be movie clip or level0 or whatever, doesn't matter as "debugbar" is a private variable of the class. Now the important part - debugbar in the library is a movieclip that contains some components - buttons and textInputs. The problem comes when trying to access these components.
I would have thought that this would work:
Code:
debugbar.input_txt.text = "hello";
In order to set the text of "input_txt", the instance name of a TextInput component on the timeline of the movie clip (put there in author time). However, this does not work. Infact, I cannot access any specific "component" properties - they come back undefined. I can however set and retrieve MovieClip properties for the "input_txt", such as _x. However there is one added strange thing with this too - setting _visible to false doesn't seem to work (however perhaps a component by default overrides this).
I also appear not to be able to add event handlers to the component - at least for the usual component events. I tried casting it to a component, such as:
Code:
var temp:TextInput = TextInput(debugbar.input_txt);
trace(temp);
which gave "temp" as null.
However if you trace the thing itself without casting to what it is, it gives the path to correctly. It almost seems like the components are somehow broken when trying to access them this way - or that they cannot be accessed this way?
The thing is, I was able to access all of this before, when the code to do it was placed on the timeline (frame 1, the only frame) of the debugbar itself, where the components were child instances. This meant I could just reference them directly too - so input_txt rather than debugbar.input_txt , although that is probably largely irrelevant. I need to have it in a class though, as I need to pass in certain objects that need to be accessed by the mc.

I'm having trouble accessing some components that reside inside of a movieclip that i'm displaying inside of a window component through the PopUpManager:
Code:
var my_MC = mx.managers.PopUpManager.createPopUp(_root, mx.containers.Window, { title:"movieClip", contentPath:"my_MC", closeButton:true });
how can i access any components that exist within the linked movie clip in my library? i have two labels that I want to update but can't figure out for the life of me how...
i've tried:
Code:
_root.my_MC.content.<label name>.text = "blah blah blah"
but no worky.

I have a list component which is being disabled while an animation is playing using It's all working perfectly but I can't for the life of me work out how to stop the whole list component going grey when it is disabled! I've changed all of the cell and component skins but it still goes grey.I just want it to stay the same colour when its disabled, or at least change it to a colour that fits with my design.

Now I wish to use the corresponding "Link" node so that each item in the list will open a web page to the link for that story. I have been able to get each title to link to the last URL link in the RSS feed.

Creating a list menu with the help of components library is simple. But how can one create a list menu which will be added dynamically? In the sense that I need the list menu to be populated with data from an external XML. All this has to be done at runtime. I cannot drag and drop a list component onto the stage.
