I retrieve XML data in Flex via HttpService. I have the resultFormat property on the HttpService instance set to HTTPService.RESULT_FORMAT_OBJECT. The result contains data similar to this:
<!-- ... -->
<children>
<item><!-- ... --></item>
[Code]....
I get an array named item beneath the element children when there is more than one item sibling. If there's only one, the conversion can't distinguish it from a scalar.
What do I need to change to have Flex convert all item elements to an array with 0 or more elements?
What would I have to do to get an array member children, dropping the item wrappers altogether?
The XML is generated by Struts on the server side. I always have the option to change the structure of the document there, but right now I'm interested in what I can do with Flex.
I'm making a first-person adventure game where I have the different frames in the root movie be the various locations that the user can interact with. I want to have fading transitions between the scenes and I was wondering if this was possible in flash. What I've tried for now is to create an array with all the current children then when the frame is changed I add those objects on top of the new frame and use a (alpha) Tween object to fade them out. This doesn't seem like a good idea and feels very hackish, so I had a few questions:
1. Is there an event that is called when a frame is changed (Event.FRAME_CHANGE doesn't exist ) since the way I'm doing it now is to have a local variable which I compare with this.currentFrame.
2. This may sound weird, but is there a way to create a screenshot of the current visible area and use that as one would any other visible object? This would allow me to Tween that one out instead of the array of children that I'm using now. I know it's possible in OpenGL, to render the current view scope to a texture array, but does Flash have this capacity?
PS: This is all done inside a separate class, in case that matters (I am very noobish).
when I create an element with this method :
this["nodeValue"+i] = new TextField();
(surely in dynamic class )
then I want to change instance name of that element.when I trace this["nodeValue"+i].name.I got a different name for that element ! f ex : instance8 .how can I get "nodeValue"+i from my element and change that .is it read only ? I want to swap tow element's instance name !
for example :
this["nodeValue"+i] to this["nodeValue"+i+1]
Is the only way to create a style sheet to create Objects for each element?

View 3 RepliesI'm developing some photo viewer app for some web site in flex 3. One of the demands made by my customers is preventing of their unique visual content from copying at least by standard Windows tools ("Print Screen" button). Are there any tricky techniques capable of doing this?

View 1 RepliesI need the user of my Flex application to be able to save a snapshot of part of the UI to a local jpg file. I got the screenshot part down - can generate an image out of any given control. However, the only way I see to let the user save the image locally is to send to my server which would return it with the appropriate Content-Disposition.

View 1 RepliesIs it able to create a SWF with for example 800x650px and to define some 'containers' within it for other SWF-files? I want to create a container for navigation at the right and when clicking on a navi element,changing the content of anorher container availalble, perhaps like'headAnimation'.
Is it able to change attributes of an included 'container'with a SWF when clicking an element within another SWF placed in a
'container'? Perhaps I have an 'container' with 'navigation.swf' within. When clicking on an elemnt .I want to start a function that fades in/out another'container'. Am I able to create a function that works for all 'containers'? E.g.like that fader so I can submit the name of a 'container' to let it fade out and I can use that function within all elements in any 'container'.
Is there anyway to take take a "screenshot", "save" or "capture" the active SWF element on a page as an image? I'd like for users to be able to simply click a button on my page, instead of having to need to manually take a screenshot of the entire page and then crop the image to show only the SWF element.I found a Jquery method, although I am unsure if it could work with SWF files. It basically captures an area of an Image element on the page and allows you to save that as a separate image. What I would need however, is to capture the SWF as the image instead. Note: I do not have access to the SWF code so I cannot achieve this using Actionscript or anything like that
View 2 RepliesI know that there is no such function as getElementByName in Flex but I also now that you can do this["object_id"] to get the element of the application u're in.What about getting an element inside another element?I've tried making element["id"] ?

View 2 RepliesI have flash where there is a link for song download. And, at the bottom of the flash I've a count, loaded thorugh flash vars which should increment everytime donload button is hit. Please let me know what approach should i take to do that. can i call a Java method on donload button which will insert a row in the table and and then get the count and render it to the count variable in my flash?
May be this extremely confusing. Here is a very similar example on how it is done. This is actually very similar to what i want to do. [URL] on this link there is count below which increments you hit the download button.
I've built a rather robust tooltip class recently that attaches and draws a single tooltip sprite to the root, then uses MOUSE_OVER to detect when it is over a tooltippable object, and shows the appropriate tooltip text. At the moment, I'm ensuring that any elements in my application which wants to take advantage of showing tooltips implement the ITooltippable interface, and expose a public getter, get tooltip().

Basically I have 14 text boxes, each box draws its content from an external txt file. Next to each text box is a button. I want the button to be either visible=true or visible=false depending on weather or not the text box has content or is "undefined" Here is what I have so far, and it's not working:[code] I would like a FOR loop to just run through the variables and check to see if any of them are undefined. if it is, then make the correct send button invisible.

I've got a spark list that gets dynamically filled.So far the new items appear at the bottom of the list. What I'd like to do is to add them at the top.The items in the list have a unique ID so some kind of sorting mechanism would probably do the trick as the new items have a greater ID than the old ones.What I'd like to avoid is some complex method behind this as I'm working on a mobile platform and the list can get quite big so I need this to be as efficient as possible.The list's data provider is an ArrayList that gets updated using binding.

View 1 RepliesI have a simple list in Flex that is populated every N seconds by a dataprovider. My goal is to avoid scrolling the list after the dataprovider has been changed.
So, before I populate the list, I save the selectedIndex, and once the dataProvider is filled, I call:
list.selectedIndex = index;
list.scrollToIndex(index);
Trouble is that this moves the selected item of the list to the top. The solution would be to get the index of the first element displayed in the list: but I have no idea on how to get that.
