Flex :: Dynamically Add Image Objects To Display And Then Interact With Them?
Jan 13, 2010
Below is sample code from a Module I have in my Flex app. I want to dynamically create mx.controls.Image objects and add them to the display. I want the user to be able to move them (this works as below) and be able to change their z-index as well as record new X and Y coords after moving back to the database. How do I determine which object in this.getChildren() is the 'selected' item the user is working with? When I add a MOUSE_OVER event, for example, it does not work.[code]

Since I've never done this and the google results are quite random, I ask here: Is it possible to display Flash movies inside a Flex application and interact with them?
The scenario is as follows:
I'm developing a new application in flex Another, already completed application is given to me as SWF (or perhaps SWC, don't know any details yet) I have to insert this second application inside in my Flex application, which should be no problem afair I have to interact with this application: send and retrieve data. Don't know any further details here, too.
Will this be possible? Or is Flex only capable of displaying the SWF without the possibility to interact with it? I hope you can understand, what I want (have to...) do.

Let's say I do something like this using Assets built in the GUI and contained in my library:
ActionScript Code:
var container:MovieClip = new MovieClip();
var tab01:MovieClip = new tabType01();

I was wondering if there was a scripting language that one could use to to interact with a flash object on a webpage? I am trying to automate some tasks but the webpage uses flash. Edit: I am trying to fill out a form basically click a few "check boxes" and then a submit button but I would like to know if its possible to automate this task.

I've got a pure AS3 (no Flex) project that uses Flare to display and interact with a data visualization. I just implemented some panning behavior, so you can click and drag the visualization around, and now I'd like to give the user a visual indicator that this is possible, by switching the arrow cursor with a nice grabby-looking hand icon.The user can click and drag at any time except when the mouse is over a clickable node (at which time the cursor swaps to a pointer - this behavior is already in place).
1) Do I need to create my own custom bitmap/sprite or is there a palette of built-in cursors I can use? (I'm not using Flex.)
2) Is there a way to simply replace the default arrow with the pan cursor project-wide, or do I need to attach the swapping to mouse events on display objects? Can I use the stage object to make this behavior apply everywhere?
3) How do I perform the swap? Do I use the Cursor object directly or do I need to get involved with the CursorManager?

I'm currently having a little trouble in a project where I have the following occuring:
Code:
preloader.swf --- loads 2x --- homepage.swf --- can load --- products.swf
When the products.swf is loaded, the starting animation occurs as expected and is displayed on the screen without an issue. However, I can't interact with any of the buttons contained in the products.swf. The products page works like an overlay over the top, and the homepage.swf contains an background which can be clicked on to close the overlay. If you click on the products.swf it reacts as if the background was clicked, which it shouldnt as the products.swf is located on top of the background.
I have already checked the obvious parts, and am ensuring that products.swf is located at numChildren-1, so nothing is getting in the way. The catch is that everything was working fine when the code was internal to the fla, and now as soon as I moved the code to an external .as file nothing works. I am using the same way of loading the products.swf as I am loading the homepage.swf, which looks like:
Code:
var productsLoader:Loader = new Loader();
productsLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onProductsCompleteHandler);
productsLoader.load(new URLRequest("products.swf"));
onProductsCompleteHandler:

I know it is possible to make instances/children interact with other objects by adding an eventListener to each child/instance.But how do you make a random instance/child interact with another random instance/child?Example: let a bunch of spaceships get damaged by a bulletrain by using addChild to place both spaceships and bullets on the stage.

basically i would like to dynamically display and preload an image onto my main movie clip. this image would be the first item in my xml file. on my main timeline i would like to have a few buttons that a user could click to change the default image on the page.
when they select a new image, i would like to have the preloader appear above the default image and then tween between the old and new image (one fading out and one in kinda thing).i sourced some code but i've been having problems preloading the first image. the image loads but the preloader doesn't do anything. it seems like the preloader doesn't seem to recognise that i'm trying to load an image. it thinks it's fully loaded and carries on before the load can begin!i would also like attach a different preloader for the first image displayed than the ones being loaded via the buttons.

I have a movie clip that displays an embedded html with a bunch of divs that are expected to hide and show other divs when the users click them. i.e. imagine that you have a span with an instruction in javascript to show a div when you click it. I already made the html file, the external css and the external js. The movieclip (in actionscript 3.0) loads and displays the html content and also the css, but i haven't managed to figure out how am i supposed to link or use the javascript to do the trick. I've tried so far doing an exhausting research over the internet for the past few days and the only infromation i've got is that web developers use externalInterface to access javascript functions, but they use flash buttons to execute the js code, and it appears to me that i cannot use or embed flash btns in my site. I don't know, I'm kinda new to flash and this is the first time I work with actionscript 3.[code]or how do I achieve de hide/show thing with another method? I'll be wandering around the site in case you have any extra doubts about this subject.

Here is part of my code in short:
[Code]....
I realized that if I do addChild, I can't really see the dynamically added component, since flex did not reserve space for my List to display. So I do parentDocument.addChild, and then it appears no problem. My question is since it's being added in the parentDocument, so it is suppose to be a component belong to parentDocument, so is that component still be able to call this handleMouseDown? From my experience, it's still able to, but which doesn't make sense to me. Can someone explain a little about why it can still work, or any better approach other than parentDocument.addChild

I want to handle the mouseevents for all the sprites on the stage including the one those are hidden behind (or overlapped or occluded) and the main condition is that I want to handle the occluded sprite (that hidden behind other sprite). example, say I have sprite1 and sprite2 on stage and I want to start drag whenever i click on the sprite and stop drag after another click.
This can be done easily, but the problem and my main requirement is that if I drag the sprite1 and drop it exactly on top of the sprite2 then sprite2 will be hidden behind the sprite1 I wont be able to drag the sprite2 without moving the sprite1 first. if you have played zynga's empires and allais game on facebook, it is handled seperatly, it is how it works in that game, the mouse event is triggered on the sprite behind the overlapping sprite, if you have two sprites overlapping one sprite than the mouse event is triggered on the sprite which is last and not the one in front irrespective of whether there is only one sprite overlapping or two or three and this happens to irregular shaped sprites (not just rectangles)

When using Loader class to load display objects (bitmaps, SWFs...) from remote URLs, is there any way for them to be instantiated (referenced as we know, by Loader::content property) as some user specified valid subclass? For example if I had a class that extended a Bitmap, is there any way for the loaded object to be of this class?

Is there any way to display flash objects which are outside the display area when flash is embeded in HTML
The reason i ask is my current project has a rotating + enlarging effect which is largely dynamic so sometimes an object may clip the edge of the stage areathis looks messy but i dont want to increase the stage area to cover the largest possible area any object could enter because most of the time the objects are at the center and small so i would end up with a lot of white space

I have a list containing display objects from throughout the application (insertion order). I want to process the list either top-down (parent, child) or bottom up (child, parent). The only requirement is that either a parent is processed before any child or vice versa a child before its parent. What is a good approach? This question is not about sorting a list. It's about retrieving the depth of a particular display object.
Example
Display list:
A (root)
B1
C1
C2
D1
B2
......
My list:
list = [E1, F4, A, B2, B1, C3, ..., N9, N8]
Bottom-up:
N9, N8, F4, E1, C3, B2, B1, A
Top-down:
A, B2, B1, C3, E1, F4, N9, N8
Does not matter if N9 before N8 or N8 before N9. Important is that any N is before M (first run) or any M before its children N* (second run).

I'm working on a web application which displays a 3D model (Acrobat 3D PDF file) and allows users to interact with the model. I need to be able to communicate with PDF from the web page:
1) Programmatically highlight a node in the 3D PDF (given the node name) when, say, the user clicks on a list item referencing that node name in the web page
2) The reverse way, know which node the user selected in the 3D PDF so I can highlight that node name in the web page.
My questions:
a) The UI of my page is Flex. Is it possible to do this interaction directly from Flex?
b) If not, is it possible to do this from browser javascript? (which I will in turn call from Flex) I have seen an article on browser-pdf communication [URL] but am not sure if 3D objects can be accessed from external browser javascript.
c) Or does the Acrobat Reader ActiveX control expose methods to perform these operations from browser javascript?
d) Lastly, do folks have any recommendations based on their experience, on which 3D CAD viewer software integrate with browsers and enable this kind of interaction? (Apart from Acrobat 3D, I am evaluating a few such as 3DVIA Composer Player).

I have a Flex application with wmode=transparent and a transparent section that allows whatever is underneath it on the HTML page to show through. In this case, what's showing through is another Flash application. This works fine, but I can't interact with the Flash application showing through.
I tried setting the z-index of the Flash app to something greater than my Flex app, and that worked, but unfortunately that solution doesn't work for my case because the Flex application has components that occasionally overlay in that area, and setting the z-index of the Flash app to be higher means those components are always stuck behind it.

I have a list with a itemrenderer. When I put a button in the itemrenderer I can not interact with it. If I rollover the button the list item rollover is triggered but not the button's rollover. I can't click on the button either. You can see below I have a click event set in the itemrenderer and it is not called on click when I run app. Must I override rollover and click methods of itemrender? Why is it such a pain to put a button in an itemrenderer?[code]...

I have a Flex project in which I am embedding a Flash SWF containing an image viewer. The SWF file I'm embedding is supplemented by an XML file, which contains a list of images to show, and an images folder containing the images. The problem I'm running into is that the embedded SWF file is unable to load the pictures. I am able to see the forward/backward navigation buttons, but there are no loaded images. When I view the SWF file outside of the Flex project it works fine. Is this because Flex isn't allowing the SWF to reach outside and access other project assets?
Here's my code for embedding the SWF:
<mx:Script>
<![CDATA[
import mx.controls.Image;
import mx.events.CloseEvent;
import mx.managers.PopUpManager;

I use a SWF file that exposes functions and events using ExternalInterface. Here is an example of an exposed function:
ExternalInterface.addCallback("myFunction", ExecuteMyFunction);
If I embed the file in an HTML page, I can access those functions using JavaScript. Now, I'm embedding that same SWF file dynamically in a Flex app using the mx:SWFLoader component, something like:
<mx:SWFLoader id="myLoader" source="[URL]" autoLoad="true"/>
I'm trying to access those exposed functions and events, but I can't find how to interact with those from the Flex app. I would like to be able to call a function just like from JavaScript, like:
myLoader.myFunction();
How can I access a function that is exposed by the ExternalInterface within Flex?
