[flexcoders] Flex with IBM Websphere / DB2
I've been working with Flex using .NET HTTP/SOAP web services and MS SQL Server for a while. Recently I started a new project using IBM Websphere Application Server (6.1) and DB2. The environment is setup with a simple Apache/Linux web server (no Websphere or other app server components), then a Webspere App Server 6.1 behind a firewall, and finally a DB2 server (also behind the firewall). The only server that is accessible externally is the Apache/Linux web server. My Flex app requires data from the DB2 database, and I'm used to getting it via HTTP/SOAP web service calls. However, with nothing but a bare Apache/Linux web server that is accessible externally, I'm trying to figure out how to best create a simple server-side HTTP listener that will take data requests, communicate with the WAS/DB2 servers, then send the data back to the Flex client. What choices/options are there for this scenario? I do have the capability of installing some server-side components to the Apache/Linux web server.
[flexcoders] Resetting HSlider / VSlider
I have a UI with filters including an HSlider with 2 thumbs representing a
start year and end year (range 1854-2008). The HSlider code looks like this:
mx:HSlider id=slider_mfg_year minimum=1854 maximum=2008 thumbCount=2
values=[1854,2008] labels=[1854, 2008] width=250 tickInterval=10
snapInterval=1 dataTipFormatFunction={nf.format} liveDragging=false
change=filter() horizontalCenter=0 bottom=5/
In addition, the UI has a reset button that is supposed to reset the filters
to their default values. Everything is working *except* the HSlider -- I can't
seem to get it to reset the thumbs to their default positions. I'm trying to do
this by setting the thumb values:
private function filter_reset():void {
slider_mfg_year.values[0] = 1854;
slider_mfg_year.values[1] = 2008;
...
However, this doesn't seem to be resetting the thumb positions, just the
HSlider control values, and the values/positions of the thumbs are now out of
sync.
How can I reset the HSlider thumbs back to their default positions/values?
[flexcoders] Link/Hand Cursor
Flex seems to be sporadic at changing the cursor to a link/hand cursor when rolled over components that allow clicks/linking. I can't find any properties that make it easy to change the cursor on roll-over of an image that is a link, for example. I don't need custom cursors or anything, I'm just interested in changing the default cursor into a hand/link cursor when the mouse is over a particular UI component. What's the best way to accomplish this?
[flexcoders] Re: Working with images of varying proportions
OK, this works great when I run the application locally, but when I
upload to the server and run it from there the images aren't being
resized (no error message - nothing happens). I tracked the problem
down to:
var img_width:int = img.content.loaderInfo.width;
var img_height:int = img.content.loaderInfo.height;
These statements work fine when running the Flex app locally, but
they cause the function to stop execution when executing the Flex app
from the web server. If I place an Alert before these statements it
displays fine, but if I place an Alert after these statements it
never shows up.
Any ideas why the content.loaderInfo would work fine locally but end
up null or undefined when running from the web server? Why the
difference? What can I do to ensure this works on the server?
Thanks!

[flexcoders] Re: Working with images of varying proportions
Yes, when I try that the images don't scale into my 160x120 box. The images are a wide variety of sizes (e.g. 300x700, 1280x1024, 150x50) they are really inconsistent in proportion. When I take off the image width/height I get the full image size and not a scaled 160x120 version. -Dan --- In flexcoders@yahoogroups.com, oneworld95 oneworl...@... wrote: Have you tried taking the width/height off of the component and see how it handles the images of varying sizes? - Alex C --- In flexcoders@yahoogroups.com, byte.sensei byte.sensei@ wrote: I have an app that loads several images into mx:Image tags with scaleContent=true and width=160 / height=120.

[flexcoders] Synchronous web service calls
OK, so I understand that Flex web service calls are asynchronous, and I understand the many cases where this makes sense since you don't have to hold up the UI experience while waiting for a web service or remote procedure to return a result. However, I keep running into instances where this makes my life hell. One example is the submission of an order on a Flex site I have. Because of the way the order is handled, it is split into multiple (smaller) orders and then each order is submitted/saved via a web service call. This means that one order could have 10+ web service calls. I have a Print Receipt button which then uses the saved order data to produce a PDF receipt. The problem is, if a user clicks Print Receipt before all the save order web services have finished, then they only get a partial receipt. There's also not an easy way to determine if all the web service calls are finished, so I can't disable/enable the button based on that. Is there any easy way to implement synchronous web service calls in Flex? Man, if I had the option of specifying with a property whether or not a web service should be synchronous or asynchronous, it would make my life *so* much easier!
[flexcoders] Re: Synchronous web service calls
Thanks for the replies. This is (sort of) the direction I was headed, although I like your specific idea below. I guess I'm still holding on to the synchronous world of coding I came from. ;) I feel like I'm always having to come up with ways to deal with Flex's asynchronous behavior, and it seems to require alot of additional code/handling (in my opinion). Anyway, thanks for the specific counter idea below -- I'll give it a shot! --- In flexcoders@yahoogroups.com, jerusalem_pilgrim [EMAIL PROTECTED] wrote: Why can't you just use a web service calls counter in your code?

[flexcoders] Re: Flash Player 9.0.124.0 - Web Services Stopped Working
I read the security update URL, and tried the URL below but it threw an error (also tried searching Adobe KB on using kb403184 but that threw an error too). Here's an example of code that works in 9.0.115.0 but not in 9.0.124.0: var ws : WebService = new mx.rpc.soap.WebService(); ws.loadWSDL(model_locator.APPLICATION_WEB_SERVICE_URL); ws.makeObjectsBindable = false; ws.useProxy = false; ws.login.resultFormat = e4x; ws.login.addEventListener(ResultEvent.RESULT, login_result); ws.login.addEventListener(FaultEvent.FAULT, app_commander.web_service_fault); ws.login.arguments.username = username.text; ws.login.arguments.password = password.text; ws.login(); So does this fall into the category of xml sockets? How do I know what port(s) it is using for the socket communication? Also, it looks like setting up a master sockets file requires port 843 to be open -- my ISP is very strict about what ports they allow and it may take several days to get this port open and directed to my master file (if it is even approved at all). So, it sounds like in my case I'll need to create my own sockets policy file and then manually call loadPolicyFile(), correct? If that's the case, what ports do I need to allow? I'm more confused that before I read the security update.

[flexcoders] SOAP Web Services not working in Flash Player 9.0.124.0
OK, I've been reading all the web content on the security changes that were implemented in 9.0.124.0. I'm more confused than ever. The security updates seem to apply to XMLSockets, and I'm not using these *unless* they are implicitly used by SOAP Web Services. Here is an example of web service code that works fine in versions prior to 9.0.124.0 but not since: var ws : WebService = new mx.rpc.soap.WebService(); ws.loadWSDL(model_locator.APPLICATION_WEB_SERVICE_URL); ws.makeObjectsBindable = false; ws.useProxy = false; ws.login.resultFormat = e4x; ws.login.addEventListener(ResultEvent.RESULT, login_result); ws.login.addEventListener(FaultEvent.FAULT, app_commander.web_service_fault); ws.login.arguments.username = username.text; ws.login.arguments.password = password.text; ws.login(); From what I'm reading, it sounds like I need a sockets policy file, although I'm not sure because this is a SOAP web service call over HTTP and as far as I can tell shouldn't be affected by the XML Sockets security update. To implement a master socket policy file seems like it requires me to configure the server with a special xmlsockets server that listens/responds on port 843. Any examples of implementing this on IIS/Windows Server? Am I missing something? Maybe I just need to update my crossdomain.xml file? I tried adding the to-ports to that but it's still not working. What do I need to do to get the soap web services working again?

[flexcoders] Simple Image Rotator
I'm trying to implement a simple image rotator that just rotates
among 5 different images. I have it working except that I want a
smooth fade out/in between each image.
To keep things simple, I implemented this using mx:states /
mx:transitions, as follows:
mx:states
mx:State name=image01
mx:SetProperty target={button_image} name=source
value=assets/images/image01.jpg/
/mx:State
mx:State name=image02
mx:SetProperty target={button_image} name=source
value=assets/images/image02.jpg/
/mx:State
mx:State name=image03
mx:SetProperty target={button_image} name=source
value=assets/images/image03.jpg/
/mx:State
mx:State name=image04
mx:SetProperty target={button_image} name=source
value=assets/images/image04.jpg/
/mx:State
mx:State name=image05
mx:SetProperty target={button_image} name=source
value=assets/images/image05.jpg/
/mx:State
/mx:states
mx:transitions
mx:Transition id=image_transition fromState=* toState=*
mx:Sequence target={button_image}
mx:Fade duration=1000 alphaFrom=1 alphaTo=0 /
mx:Fade duration=1000 alphaFrom=0 alphaTo=1 /
/mx:Sequence
/mx:Transition
/mx:transitions
The problem I'm having is that the image source is getting replaced
before the transition starts, so the image pops to the next image
and then the new image does a fade in/out. I understand why it's
doing this, what I don't know is how to change it so that the fade
out happens *before* the image source is changed, and then the fade
in happens *after* the image source is changed.
I can think of way(s) this might be done by scrapping the
states/transitions approach and just writing ActionScript, but I was
wondering if there's any easy way to modify what I've already got
instead of scrapping it and going in a new direction.
Thanks in advance for any feedback.
[flexcoders] Load HTML from URL into Flex Component (via iframe)
I've got a Flex site with several pages that load HTML content from an
older HTML version of the site into an iframe that I then place over the
Flash movie so it looks like the content has been embedded into the Flex
UI even though it's still being loaded from the old HTML site.
I've got the following Javascript function to load the HTML content into
the iframe:
function loadIFrame(url){
document.getElementById(myFrame).innerHTML = iframe id='myIFrame'
src=' + url + ' frameborder='0'/iframe;
Alert.show(url);
}
I added the Alert.show for testing so I'd get a Javascript alert box
if/when this Javascript function fires.
Inside my Flex app, I'm using the following code to refresh the iframe
based on a URL:
ExternalInterface.call(loadIFrame, source);
I'm using the show event of a VBox component to make the
ExternalInterface.call to the Javascript function. I've verified via
trace that the show event is firing and the ExternalInterface.call()
function is executing, but the iframe never loads the URL nor does the
Javascript Alert.show() function execute.
It seems to work some of the time, but not consistently and not in any
pattern I can distinguish. Am I missing something here? Is there a
different/better approach for loading HTML content via an HTTP GET into
a Flex UI? If not, how can I get this to work properly/consistently?
Cheers!
[flexcoders] Re: Load HTML from URL into Flex Component (via iframe)
OK, so I fixed the Javascript to use the correct alert box code (I've
got Flex syntax on the brain):
alert(url);
Now I see that loadIFrame() is executing -- but it executes 3 times,
or at least I'm getting 3 javascript alert boxes each time I load the
iframe page.

[flexcoders] Strange Page Titles with HistoryMangement
Ever since I enabled HistoryManagement on a Flex app the HTML Page
Titles have been messed up. Instead of my normal page titles, the
page title becomes something like #app=e75-action=...
I thought that putting a hard-coded Page title into my
index.template.html would fix the problem (and always use my static
page title) but this didn't work, either.
In index.template.html I changed: title${title}/title to
titleTESTING/title. When I FIRST load the Flex app, it shows
the TESTING page title, but as soon as I start using the site it
reverts back to the garbled titles.
When I view source on the page (via IE) I see the
titleTESTING/title in the head of my HTML wrapper, but IE is
*still* showing the garbled page titles.
How can I set the Page Title so it doesn't get messed up?
[flexcoders] Browser window size
This is probably a simple question but is there an easy way to get the current browser window size? I have a Flex app with the application height/width set to 100%, and then I divide that up into various vbox/hbox elements. However, in some instances I create a pop-up with PopUpManager. The problem I'm having is that the pop-up might end up being too tall for the browser window size, and it ends up going off the screen without any way to scroll. There's a vertical scrollbar on the main screen, but since it's behind the pop-up there's no way to use it. In other words, the application height may be larger than the browser window height (which just engages a vertical scroll bar) but the pop- up *thinks* it can use up to the application height when in reality I want to limit it to the (current) browser window height. For now, I've set a maximum height of 400 pixels (which I know will fit on an 800x600 screen) but when the user has a higher resolution I want to be able to make the pop-up height larger than 400. Ultimately what I want to do is create a VBox pop-up and then on creationComplete check its height against the current browser window height, and if it's larger, reset the height (which turns on the vertical scroll bar) but otherwise leave the height alone (no vertical scroll bar).
[flexcoders] Re: Browser window size
Both suggestions worked -- I implemented the javascript / ExternalInterface method first, then saw the other reply and that worked out, too. I kept the systemManager.screen version since it doesn't require Javascript, and the Javascript code I was using to detect the size of the current browser window isn't exactly bullet- proof. Thanks to both of you for the replies!
[flexcoders] Save/Recall a Password field?
I have a Flex app where the first screen is a Login page. This is replacing an ASPX/HTML site, and one thing I never realized was how much users rely on the browser's ability to remember passwords. Now that I've launched the new site, a lot of users are asking why it doesn't save their password for the next time they come back. Has anyone tried to interface with the browser's password save/recall capability? This happens automatically on HTML/.NET forms. I'm exploring other possibilities, like making the Login page an HTML form and *then* loading the Flex app *or* saving the username/password in a local shared object and recalling it the next time the user comes back (emulating the browser's built-in password save/recall).
[flexcoders] VBox content not refreshing on scroll
I've noticed in several places that when scroll bars are used that the content in whatever component is being scrolled doesn't get updated. I have several different Canvas and VBox/HBox screens with a vertical scroll bar, and when you scroll up and down it seems to jumble up the content and even after you stop scrolling the content remains jumbled -- like it needs to be refreshed to draw everything in the correct positions. I'd really like to understand *why* the content isn't keeping up with the scroll and ends up all jumbled up. Of course I'd also *really* like to know how to fix this issue...
[flexcoders] Re: VBox content not refreshing on scroll
Sure, try http://www.symetri.com/flex_test/test.html http://www.symetri.com/flex_test/test.html If you use the vbar to scroll up/down you should see what I'm talking about -- the form content gets messed up. Then, if you roll the mouse around the VBox after scrolling it usually refreshes the item as you roll over it, causing it to jump as it shifts from the jumbled position to the actual position. I've even seen it where the buttons are totally gone and then you roll the mouse over and they suddenly reappear. While putting together is test case, I figured out the source of the problem. I had added wmode,opaque to my AC_FL_RunContent in index.template.html. On the actual site/project I've added more stuff, but for this test case I used the base index.template.html and only addded that one line (after I figured out that was causing the issue). I added the wmode,opaque for a reason (to fix a previous issue) -- I just can't recall what that issue was. I hesitate to take it out, but I might not have a choice.

Quick addendum: I remembered why I added wmode,opaque to my AC_FL_RunContent -- I'm using a hidden iframe in the HTML wrapper to pull in content from another site on certain pages. I had read that for this to work properly you had to add wmode=opaque to the html wrapper...
[flexcoders] Enabling/Disabling Components
What's the easiest way to make components visible/invisible in a VBox/HBox so that they collapse their real estate. When you just set visible=false, the space for the component is still reserved in the associated VBox/HBox. In addition, setting width=0 or height=0 collapses the space for the component but doesn't collapse the gap space between components. Is there an easy way to keep components in a VBox/HBox so they are still available via Actionscript but make them invisible *AND* also collapse their real estate (including gap space)? A common example: I have a form that shows either a combo box *or* a text box depending on selections made by the user. When the form changes from one to the other, I want to keep both controls but make one invisible (and collapse the associated space). I can do this with a Canvas using absolute layout (I just make the controls overlap and then set one visible and the other invisible), but I'm tyring to get it to work in a VBox/HBox form if possible.

[flexcoders] Specifying Component Height/Width Percentages via Actionscript
Is there an easy way to specify a component height/width in percentages rather than pixels via Actionscript? I have a UI that has 2 VBox components. By default, the height of the top is set to 100% and the height of the bottom is 0. However, I want to be able to dynamically change the heights to 85% / 15% using an Actionscript function. I tried setting height/width using a formula to calculate the correct height in pixels, which seemed to work until I resized the browser and realized that Flex had changed the VBox heights to static pixels, so they no longer scaled as the browser window was resized (i.e. their heights where now static pixels instead of percentages).

[flexcoders] Load HTML from URL into Flex Component
I have a Flex 3 application that generates HTML, PDF, and Excel reports
from SQL Server Reporting Services.
In the case of HTML, I've been using navigateToURL() to load the result
into the browser. This works fine, but I'd really like to embed the
HTML into a Flex container and wrap the application
navigation/header/footer around it so that the user stays in the Flex
app and has access to all of the site navigation, etc.
In the Flex/AIR documentation there's lots of examples that use
HTMLControl / URLRequest to load the HTML content of a URL and then add
the HTMLControl display object. However, the required
flash.html.HTMLControl library is not available in Flex.
I tried using flash.display.Loader / URLRequest and then used
this.rawChildren.addChild() but that doesn't seem to work either - the
page is just blank. I thought maybe I needed to specify the
height/width but that didn't make any difference. Here's the code I'm
using:
import flash.display.Loader;
import flash.net.URLRequest;
private function load_html() : void {
var html:Loader = new Loader();
var urlReq:URLRequest = new URLRequest(http://www.symetri.com/;);
html.width = 900;
html.height = 900;
html.load(urlReq);
html_box.rawChildren.addChild(html);
}
The function runs on creationComplete() of the html_box VBox container.
Isn't there some type of HTMLLoader Flex component similar to SWFLoader
out there somewhere that will do this sort of thing? If not, any other
suggestions?

[flexcoders] Flex 3 Beta 2 Expires in 4 days
I was recently forced to upgrade from Flex 2 to Flex 3 because of a bug in Flex 2 that was fixed in Flex 3 that was affecting a couple of projects I'm working on. Flex 3 Beta 2 has been great, however it looks like it's set to expire in 4 days (not sure if that's just my machine or a fixed date for all beta 2). The problem is, I can't buy Flex 3 (yet), and I don't see a new beta/version of Flex 3 with a later expiration date. What can I do to keep developing in Flex 3? I purchased Flex 2 last year and I have that serial, but I'm not sure if Flex 3 will accept it. Will there be another beta update before the current one expires?

This whole thing ended up being caused by the following statement I

and everything compiled normally.
Sure enough, I was able to repeat the problem in a blank test.mxml

mx:Script
![CDATA[
import mx.events.StateChangeEvent;
public function my_function(event:StateChangeEvent) :

[flexcoders] Flash CS3 Components - Custom Properties Methods
I've been experimenting with Flex SWC Components developed in Flash
CS3 (using Flex Component Kit for Flash CS3).
I've successfully created some custom properties/methods on these
that I can use in Flex. Here's a quick example of a UIMovieClip
class extension:
package {
import mx.flash.UIMovieClip;
public dynamic class forestDragon extends UIMovieClip {
public var current_state : String = ;
public var my_name : String = ;
public var my_color : String = ;
public function forestDragon():void {
}
public function fly_begin():void {
gotoAndPlay(1);
}
public function fly_end():void {
gotoAndStop(1);
}
}
}
So, in Flex I can then get/set the current_state variable and call
the fly_begin() and fly_end() methods as needed to start/stop the
component animations.
All of this works great, but I'm now faced with a new challenge. For
example, I want to be able to set my_color and/or my_name via Flex
and then have it change the color of the Flash object or change the
text underneath the animation to whatever my_name is set to, etc.
However, I can't figure out how I can reference these properties or
use them to control aspects of the Flash movie clip. I first tried
creating a dynamic text instance on the Flash movie clip but whenever
I publish the SWC it's throwing an error. I can add dynamic text
elements to the Flash movie clip, but if I give it an instance name
it won't compile/export.
Obviously, the real strength of Flex Components developed in Flash
CS3 comes when you can take advantage of custom properties/methods to
change aspects of the Flash movie clip dynamically via Flex. Am I
approaching this the right way, and if so (or not) can anyone provide
some direction/insight on how to accomplish this?
Thanks!

[flexcoders] Flash CS3 Components - Tweens in Flex
I have some Flash CS3 animations (characters walking/running) that I have exported as Flex 2 components (SWC files) using the Flex Component Kit for Flash CS3. I create an instance of the component in Flex, then need to be able to have the character move to the mouse position when a user clicks. As an initial test, I used a PNG image and setup a move tween, which works great. However, as soon as I try and use the Flex component, I get an Error #1006 -- apparently the tween doesn't work on the Flex component object type. Basically, what I'm trying to do when a user clicks is: Put the Flex component into an animated walking state (from a static/standing position) then have the character move across the screen to where the mouse was clicked. I've got the first part working great (the character starts the walking animation loop) but the Flex move tween is throwing the error. Any ideas on how to accomplish this? Note: I also need a simultaneous zoom tween to scale the character slightly for perspective -- again this works when I use a static image but throws the same Error #1006 when I try and apply it to the animation Flex component.
[flexcoders] Motion/Zoom Tweens on Flash CS3 Components
I have a Flex app with some animated characters that (are supposed to) move around the screen when you click the mouse. The animations are done in Flash CS3, then exported as Flex SWC Components using the Flex Component Kit for Flash CS3. Initially, I used static JPG/PNG images for characters, and created Move/Zoon tweens in Flex that would move the images around the screen. However, when I replaced the static images with the SWC components, it didn't work. The characters properly change from a standing state to a walking state (looping animation) but when I try to play the move/zoom tweens it throws an error (Error #1006). Researching this error it seems it can happen when the object you are applying a method to is the wrong type. But shouldn't I be able to use this method to move the SWC components around the screen? If not, how can I move/zoom the SWC components when a user clicks the mouse? Essentially, a mouse click should cause the character to enter the walking state/animation, then play the move/zoom tweens to take the component to the mouse click position, then return the character to a standing state. Any insight is appreciated!
[flexcoders] DataGrid itemRenderer

format numbers:
public function format_number(num : Number, format : String) : String
{
var formatter : NumberFormatter = new NumberFormatter();
var str : String;
switch (format) {
case currency:
formatter.precision = 2;
formatter.useThousandsSeparator = true;
str = $ + formatter.format(num);
break;
case percent:
formatter.precision = 1;
formatter.useThousandsSeparator = true;
str = formatter.format(num*100) + %;
break;
case decimal2:
formatter.precision = 2;
formatter.useThousandsSeparator = false;
str = formatter.format(num);
break;
case cuft:
formatter.precision = 1;
formatter.useThousandsSeparator = true;
if (num 0) { num = 0 }
str = formatter.format(num);
break;
default:
str = String(num);
break;
}
return str;
}
However, I can't figure out a way to utilize this function on my
DataGrid columns. I've tried creating both inline and external
itemRenderer components, but in both cases I don't see a way to
inject the required Actionscript into the itemRenderer component -- I
keep getting compile errors when I try to use an mx:Script block in
the component.
Anyone know of a way to make this work?
[flexcoders] Re: DataGrid itemRenderer
Awesome - works great. Thanks Alex - sometimes the biggest problem
is figuring out that something like labelFunction exists. I read
through the Flex help docs but must've somehow overlooked this.

Subject: [flexcoders] DataGrid itemRenderer
I've been pulling my hair out trying to figure out the best way to
format numbers in a DataGrid. I've got a dataProvider with fields
used in the grids that are of type Number -- some are currency,
some are integers, and some are numbers that need to be formatted
to
1 decimal point.
In other places in my application, I'm using a custom function to
format numbers:
public function format_number(num : Number, format : String) :
String
{
var formatter : NumberFormatter = new NumberFormatter();
var str : String;
switch (format) {
case currency:
formatter.precision = 2;
formatter.useThousandsSeparator = true;
str = $ + formatter.format(num);
break;
case percent:
formatter.precision = 1;
formatter.useThousandsSeparator = true;
str = formatter.format(num*100) + %;
break;
case decimal2:
formatter.precision = 2;
formatter.useThousandsSeparator = false;
str = formatter.format(num);
break;
case cuft:
formatter.precision = 1;
formatter.useThousandsSeparator = true;
if (num 0) { num = 0 }
str = formatter.format(num);
break;
default:
str = String(num);
break;
}
return str;
}
However, I can't figure out a way to utilize this function on my
DataGrid columns. I've tried creating both inline and external
itemRenderer components, but in both cases I don't see a way to
inject the required Actionscript into the itemRenderer component --

keep getting compile errors when I try to use an mx:Script block in

[flexcoders] tabNavigator - dynamic tabs?
I have a tabNavigator with 3 mx:Canvas tabs, each containing a dataGrid for a different user/customer. Above the tabNavigator you can select up to 3 different users/customers, and this populates the associated grid in the tabNavigator. Pretty straightforward -- *except* that I don't want the tabs in the tabNavigator to be visible until you've selected a user/customer above. I tried setting the visible property of my mx:Canvas containers, but the tab still shows up regardless of whether the child is visible or not. Is there a way to prevent tabs in the tabNavigator from showing up? I could always dynamically add/remove the child mx:Canvas objects via actionscript, but in this case it's always 0-3 and I'd rather just create 3 mx:Canvas objects in MXML and then show/hide them as needed. I'm just baffled that visible=false on the mx:Canvas child objects doesn't take away the tab in the tabNavigator! Is this by design?
[flexcoders] Embedded SWF in Flex 2
I have a Flex 2 app with an embedded SWF file that I'm loading into Flex with mx:SWFLoader. The swf file is a fairly complex form written in Flash 8 / AS 2.0 that uses xml web services to pull data into a form which is edited and then re-submitted. Once a user is finished with the embedded swf form, (s)he clicks a button which saves all the form data via another web service call, then I *want* to pass control back to the Flex app with an event or trigger that I can recognize to continue the data entry process. How can I get the embedded swf form to trigger an event and/or function in the parent Flex 2 application? I also need to pass a variable back to the Flex app. So, in a nutshell, when a user clicks the submit button of the embedded swf form, I need it to save the form data then pass a variable (e.g. CartID) back to the Flex app and let Flex handle the process from there. Any thoughts on how to accomplish this? NOTE: I've set trustContent=true in the mx:SWFLoader, but I can't seem to find any decent documentation on how to access the parent Flex app functions/events or pass data back and forth, etc.
[flexcoders] Flex / Web Integration
I have a Flex 2.0 app that has to open a URL used to configure a shopping cart item. When finished configuring an item and you return to Flex, Flex calls a web service to retrieve the item configuration and all is good. Currently, I'm opening a new browser window using navigateToURL() with _blank for the target. This presents a couple of problems: 1) When the item configuration is done and the window is closed (using Javascript) I get the annoying The webpage you are using is trying to close the window and you have to verify that you want to close the window. 2) I don't have any good way to detect the window was closed and then fire off the web service to get the item configuration -- I basically have to wait for the user to do something back in the Flex app that causes an event to fire that I can trigger on. (I'm currently using the focusOut event of the Quantity field in the item data grid, but there's no guarantee the user will click/tab into a quantity field and then back out after configuring an item...) So, does anyone know of a way I could open a new window/url for the item configuration, but then return to the Flex app without the Do you want to close this window? dialog box AND in a way that would fire a Flex event I can use to trigger the web service call? I don't have any control over the item configuration URL/code -- it's a 3rd party application I'm integrating with... Thanks in advance for any insight/help!
[flexcoders] Re: Flex / Web Integration
I solved my own problem and thought I'd post the result here for
posterity...
For #1 below, I switched to using the javascript window.open
command instead of navigateToURL() with _blank for the target.
Specifically, I'm using the following AS 3 code:
import flash.external.ExternalInterface;
public function open_window(url : String, window : String = _blank,
features : String = ) : void {
ExternalInterface.call(window.open, url, window, features);
}
For problem #2 below, I found the activate event and use it to
detect when Flash Player receives focus after the pop-up window is
closed, and then call the web service -- works great!
