Re: [flexcoders] Advantages and Disadvantages of skinning
The new skinning architecture in Flex 4 separates business logic and design for a component. The component itself contains only the functionality (the M and C of the MVC pattern) and the skin defines its visual aspect (the V of MVC). If used correctly, you can change the design (skin) of a component without the need for changing the code of the component itself. One component and many skins, e.g. for desktop, for mobile, for different applications. Skinning is very good documented and there are many resources available, just search for spark skinning.

Re: [flexcoders] Need help dynamically modifying text displayed based on DB return
I think the best way is to use states. Define the different states for your
component, e.g.
s:states
s:State name=available /
s:State name=sold /
s:State name=other /
/s:states
You have now to track changes to win.status and set the current state
accordingly, e.g. by listening to the property change event on win:
protected function win_propertyChangeHandler(event:PropertyChangeEvent):void
{
switch (event.property)
{
case status:
imageStatus = event.newValue;
switch (event.newValue)
{
case Available:
currentState = available;
break;
case Sold:
currentState = sold;
break;
default:
currentState = other;
break;
}
break;
}
}
and finally set the properties of the artPrice text based on the current
state:
s:RichText id=artPrice width=120 color=#00
color.sold=#C39F70 fontFamily=Times New Roman fontSize=18
text={imageStatus} text.available={imagePrice} /
I hope this helps.

[flexcoders] P2P multicast and upstream bandwidth
Hi, I'm in the process of developing a realtime video chat application where multiple users can send video streams simultanuously. The number of users receiving the streams can be very big, e.g. 10 broadcasters and 500 receivers, each receiver should get all streams. I use RTMFP connections to an FMS and streams are published in P2P multicast groups by passing the groupspec to the NetStream constructor. Currently I'm having problems with audio/video synchronization and video stream 'jumps' (not continuous). From what I read in the internet, this is related to the fact that there is not enough upstream bandwidth for sending the streams. So my questions are: 1. How to calculate the required upstream bandwidth on every peer for the given example of 10 broadcasters and 500 receivers (is it 10*bandwidth of one stream)? 2. What settings (on NetStream, Camera, Microphone etc.) should be used for best results and how to adapt them based on the number of broadcasters? I hope my questions make sense!

Re: [flexcoders] You are the product
Interesting answers but they almost all are based on the assumption that you have much time and enough money to waste. You can do almost everything with HTML/JS/CSS, but for many things you will require much (really much) more time than with Flash. I say 'almost' because there are things you can't do, an example is applications using peer-assisted networking (peer-to-peer), which is a realworld project I'm working on currently. Let's stop this war because both technologies are complementary and there are things you should do with one technology and others with other technologies. Now regarding the attitude of Adobe, it's true that the way they did the annoucement was not 'friendly', but it was actually a logical decision. There is no flash application on the web that was designed with mobile devices in mind. Users generally install apps on their devices and we have AIR for that, especially with the new native extensions there is no limitations to what you can do anymore. Developing using Flash and native languages for extensions is a new way of developing applications and it should be the same for web apps, where we develop with Flash and HTML. The reality is that every technology has its advantages and as a developer you have to know when to use each one.

Flash might be a good choice for one and HTML for another and you might need to go native depending on what you are trying to do. Maybe you even want to use Java or Silverlight! When you ask if you can do something in HTML5/JS/CSS you need to keep in mind that many of the specs are not yet finished. It will be several more years before they are even in the recommendation phase. So while it may be possible to do some things in some browsers HTML5/JS/CSS is far from being cross platform ready. Standards move slow by their nature and because of that browser vendors will release features before the standards are finished, many times that means that each browser will have a different API or implementation for the same feature. If you are going to use newer html features it is recommended that you only use the ones that are relatively stable. May of the really cool features that you will want to use are not yet production ready and should be avoided for a real project. Of course if you can limit your scope to a couple browsers there is a lot more you can do. All of that said you can make some really kick ass stuff using the HTML5, CSS3, and JavaScript. There are tons of libraries that will abstract out the browser specific things and attempt to make one code base work everywhere. Things like Modernizr, Three.js, Dojo, jQuery, EaselJS ,ect, ect. Even when using these libraries there are performance differences across devices and even browser versions.

Re: [flexcoders] Why Flex now?
Because today HTML5 is not yet ready and will not be ready for the next 5-10 years in my opinion. There are still many things you can only do in Flash and many other that are very difficult to do with HTML5. In my opinion HTML5 is a hype anyway, some new tags, css and js elements and functions. Browser-compatibility, layout, animation, video and much more is handled very easily with Flex/Flash. Should we replace the strong-typed and compiled AS 3 language with JavaScript? I'm working on a video chat application that uses FMS and P2P multicats, can you do that with HTML?? Personnally I don't think Flex is dead, the Flex community will continue to implement it and there will be some companies offering support for it. Only when Adobe stops the development of the Flash player for the Desktop I will say that Flash is really dead. Let's help the Spoon project and make Flex better than ever!

Given our experiences innovating on Flex, we are extremely well positioned to positively contribute to the advancement of HTML5 development, starting with mobile applications. In fact, *many of the engineers and product managers who worked on Flex SDK will be moving to work on our HTML efforts*. We will continue making significant contributions to open web technologies like WebKit jQuery, advance the development of PhoneGap and create new tools that solve the challenges developers face when building applications with HTML5. Emphasis mine. If anyone has followed any game or application development where 'many members' of the team are switched to the next greatest thing, that normally means there are few maintenance developers for the existing product and not much new innovation to it. The company wants its best and brightest working on its future, not supporting its past. Combine that with the facts that Adobe bought PhoneGap and released Edge preview. It's not hard to put all these facts together and see that long term they want an IDE framework for app development in HTML5. Perhaps Flex5 will be an HTML5 version of Flex as they start putting together html5 components Outside of having to support IE6 why would you choose to start a project in Flex today?
Re: [flexcoders] Restrict access to an API to only allowed applications

Re: [flexcoders] Re: Is it possible to add Flex components to the Stage?
if for some reason you don't want or can't use Flex, then you try some of
the pure AS component libraries:
* ASDPC : http://sibirjak.com/osflash/projects/as-dataprovider-controls/
* AsWing : http://www.aswing.org/
and there are more.

Re: [flexcoders] e4x help
because the elements are then defined in the namespace
http://schemas.dell.com/wbem/biosattributeregistry/1;. To access them
through e4x you have to create a corresponding namespace object, e.g.:

Re: [flexcoders] What is the a correct lifecycle phase to add new child components?
Hi Nick,
if you use Spark components and the child components you want to add are
fixed and known, e.g. a 'close' button that should be visible on mouse-over,
then I would use skin states and manage visibility of the components in the

Yes. To take advantage of the spark architecture you have to extend
SkinnableComponent (or one of the other SkinnableXXX classes, depending on

Re: [flexcoders] Constraining one components location to another component
Hi,
I think the best way is to create a new component that will hold the image
and the floating components and handle visibility of these components
through states.
Example:
?xml version=1.0 encoding=utf-8?
s:Group
xmlns:fx=http://ns.adobe.com/mxml/2009;
xmlns:s=library://ns.adobe.com/flex/spark
xmlns:mx=library://ns.adobe.com/flex/mx
s:states
s:State name=normal /
s:State name=loading /
s:State name=error /
/s:states
fx:Script
![CDATA[
[Bindable]
public var source:Object;
]]
/fx:Script
mx:Image
id=image
source={source}
complete={currentState = 'normal'}
progress={currentState = 'loading'}
ioError={currentState = 'error'}
/
s:Label top=0 right=0 text=Loading... includeIn=loading /
s:Label top=0 right=0 text=Error! includeIn=error /
/s:Group
Of course you can put any states you like and also set states from outside
with : mainImage.currentState = .

When the button icon is clicked(which is noted in bold above), another
new window W2 is opened using the below function
public function openmyWin_fn(eventObj:*):void
{
//Keeps multiple windows from being opened
if(result_win == null){
result_win = PopUpManager.createPopUp(this,
result_win, true) as result_win;
}
//Passes the parent object to the popup window
result_win.openingParentWindow = this;
//Set the mode (Add or Update) in which the form should
operate
result_win.form_mode = eventObj;
}
I tried to add a TextInput in the above MXML in Window W1's source which
led to the window W2 opening in the rightmost part of browser window
without a scroll bar instead of appearing with a scroll bar in the
center of browser window. W2 should be appearing as overlapping W1, not
adjacent to it.
I commented the TextInput I added, even removed it, still the
issue(window W2 opening in the rightmost part of browser window without
a scroll bar) persists.
I once faced this problem where inadvertently a height value was added
to the whole W2 window. After I removed it, the window W2 was fine. This
time I am comparing the source files before I added the TextInput
control and after I removed it(when the window W2 was not displaying in
the proper place) and the source files are identical.
Window W2 was having scrollbars before I tried to add the TextInput MXML
control. It was also centering in the application before I tried to add
the TextInput MXML control.
Where could I be erring to cause the W2 to appear in the rightmost part
of browser? I don't understand what is causing it to happen if the

[flexcoders] Multiple instances of a module with different styles
Hi, I have a Flex 4 application that loads modules dynamically. The modules load style files dynamically based on their configuration files, so that every module can load different style files. If multiple instances of a module are created (with multiple ModuleLoader instances having the same url), everytime an instance loads a style file, it gets also applied (partially) to the other instances so that all instances end up with mixed styles. I originally thought that the per-module styles feature of Flex 4 should allow every module to apply its own styles, but it seems like it's more a per-module-type style. Is there any way to load styles per module instance? Thanks, Haykel Ben Jemia Allmas Web RIA Development http://www.allmas-tn.com
Re: [flexcoders] Multiple instances of a module with different styles
Hi Alex, ok it's clear with the factory. But how can I handle the following scenario with class selectors : Module 'MyModule': * Module has a button with style name 'myButton' * Module gets a url for a style file from main application and loads it with styleManager.loadStyleDeclarations(mystyle) Application: * Creates ModuleLoader 1 with url 'MyModule.swf' and pass it style url 'style1.swf' which defines 'Button.myButton' with text color red * Creates ModuleLoader 2 with url 'MyModule.swf' and pass it style url 'style2.swf' which defines 'Button.myButton' with text color green I want to have one module with red text and the other with green text. What I'm getting now is that both use sometimes one color and sometimes the other, I think depending on which styles are loaded first.

You can use the getScrollPositionDeltaToElement() function of the layout and add the x value of the returned point to the horizontalScrollPosition.

[flexcoders] Strange mask problem
Hi, I'm trying to create some sort of sprite using the Flex 4 'Path' graphic element. The idea is to create the Path element that defines the visual look of the sprite, then another one with the same properties in a Group but using a black color with alpha set to 1. Then use this group as the mask for the sprite and set the mask type to 'alpha'. This also works but only when the sprite has the position (0, 0). When it is moved, it is displayed correctly but mouse interaction is broken. Please find an example here: http://www.allmas-tn.com/files/tests/fxgtests/FXGTests.html The application has 'view source' enabled. Any idea why even though the mask is correct (because the geometry is displayed and not masked out), mouse interaction is broken when the object is moved?

Re: [flexcoders] Hide/Show parts of a From
How are you creating the form, mxml or AS? If mxml, you could create a
bindable Boolean property for each group and set the visible property of
each item set to the value of the corresponding group and just change that
one variable to show/hide a group.
Example:
[Bindable] private var group1Visible:Boolean = true;
[Bindable] private var group2Visible:Boolean = false;
FormItem visible={group1Visible} ...
FormItem visible={group1Visible} ...
FormItem visible={group2Visible} ...
FormItem visible={group2Visible} ...
Somewhere in your code:
group1Visible = false;
group2Visible = true;

Re: [flexcoders] Strange mask problem
Same result. Actually the mask is correct, because if I add a Rect to fill the component, it is being masked correctly and only the portion under the Path is displayed. The only thing that's not working is the mouse interaction when the component is not at position (0,0). To summarize again: * At position (0,0), everything works correctly. * At any other position, display masking is correct but mouse behaves incorrectly. This sounds like a bug, any thoughts?

Re: [flexcoders] Flex 3 to 4 Path
Hi Lee, I have ported an application from Flex 3 to Flex 4 and here are the points I can remember: - The good news is you don't need to replace the halo components with their spark equivalents at the beginning - You should use the Spark theme and correct any errors to be ready to go with Flex 4 skinning - Some styles are not supported anymore with Spark and need to be handled differently - Where you need containers with borders and background colors/images use the spark BorderContainer (bg colors don't work with Canvas, that was the case for me, I don't know if this is general) - You will need to add namespaces for styles, for the beginning you can simply define the mx namspace as the default namespace: - @namespace library://ns.adobe.com/flex/mx; - You must change all StyleManager references with styleManager (new property of UIComponent) - Don't reference modules by class name, use interfaces instead. For example if you have a module called MyModule and load it with a ModuleLoader loader, don't do var module:MyModule = loader.child as MyModule to access it. Define an interface, i.e. IMyModule, make MyModule implement it and do var module:IMyModule = loader.child as IMyModule. Otherwise you can have many strange runtime errors. For the start you can also disable per module styles with the compiler option '-isolate-styles=false' until you have finished correcting these module issues. - You have to use the new syntax for states and transitions. Always use the spark transitions ans effects as they work much better than the halo ones. I think that's it for now!

Re: [flexcoders] Flex 4 and StyleManager
Hi, Flax 4 supports per-module style management and the StyleManager is not a singleton anymore. Each module has its own StyleManage and you have to reference that one. For UIComponent and subclasses (all visual Flex components), the style manager is available in the styleManager property. For your example, simple change the uppercase 'S' of StyleManager to a lowercase 's': styleManager.loadStyleDeclarations(styles/BlueBackground.swf, true); Bye, Haykel Ben Jemia Allmas Web RIA Development http://www.allmas-tn.com On Thu, Apr 22, 2010 at 9:25 AM, bobby_world bobby_wo...@yahoo.com wrote: Hi!

Thanks Alex for the quick response.
However, the button is supposed to turn enabled after the result is
returned.
The problem is that while it looks like the button is disabled -
clicking on it results in entering to the function which listens to it.
Moreover, I logged/traced the time the the button turns back to enable
+ the time entering to the function that listens to it -
it's exactly the same - by the millisecond.
meaning - i can't event log the time the button was clicked - cause
the mouse click event is only dispatched after the button turned enable.
one last thing - I found a workaround by removing the eventListener
when the button is disabled , and adding it back with a timer that
starts counting after it turned enabled in ticks of 100ms. ( the the
clicks are not listened in that time space of when the button turned
enable and 100ms after that).
The thing is that i don't want to use a timer... it's a very ugly
solution.

One simple way to do it is to create a component with two states: 'progress' and 'image' for example.

Re: [flexcoders] RTL with FP10, Flex 3
I wanted to suggest Flex 4 also, but it's still alpha! I had to use it for a project because I needed support for the Arabic language, but I often faced problems with bugs in the framework and renamings made to the classes/functions. In the same time I found the new skinning concept and DOM structure very helpful and I have sometimes some difficulty to go back to Flex 3 :) Anyway, if you are ready to put some time in finding bugs and to cope with changes that can break compilation of your project after a svn update (I would estimate it to be 10%-15% of your time), then I would definitely advise to use Flex 4.

Re: [flexcoders] Im new, and this is an old question
RIA doesn't mean no pages. There are situations where you have simply different pages. How you implement them, as different apps, modules or as a viewstack depends. But among other things, a RIA reduces page loading in many cases. In your example, the login can be a page and the calendar another page. But in the calendar page, if the user chooses to see the details of an item, edit an item, add a new one or add a comment for example, then you can do all this in one page. So I would split the app by functionality and implement the different parts independently, then you could put them on different pages or load them as modules.

If I embed this component (call it MyComp) like this:
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
view:MyComp currentState=state1/
/mx:Application
the transition takes place as the component appears, and everything is
fine. But if I put it inside a FormItem, like this:
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
mx:Form
mx:FormItem label=Type
view:SectionTypeControl currentState=taskQueue/
/mx:FormItem
/mx:Form
/mx:Application
the transition never takes place and the two labels remain superimposed.
In fact the problem is a little worse than this. In the toy
application above, you can replace FormItem by a container like HBox
and it works again. But in my real app I can't use it inside a Form
at all. What gives?

Re: [flexcoders] Re: Do states and transitions behave differently depending on the context?
Why do you need the one state? Is it only to make the transition when the
component is created or do you have other states? What do you want to
achieve exactly? Perhaps there is a better solution!

Thanks very much! It looks as though the transition will work - or not -
depending on when it's invoked in the component creation process.
And invoking it at the wrong time (ie as part of initialisation, as I
did) prevents it from working later, as in your solution.
Transitions seem to have a very steep learning curve. The solution
for the toy example /still/ doesn't work in my real application! So
there must be some other inexplicable glitch to be isolated...

Re: [flexcoders] flex not seeing method
I don't know if this is related, but there is one problem with the name of
the event. The event is downloadresizeevent, while in the meta declaration
and the event handler you are calling it DownloadResizeEvent.
You will have either to change the event's name with:
public static const DOWNLOADRESIZE_EVENT:String = DownloadResizeEvent;
or correct how you reference it:
snip
mx:Metadata
[Event(name=downloadresizeevent, type=elib.event.DownloadResizeEvent)]
/mx:Metadata
snip
snip
view:componentmxml downloadresizeevent=handler_resize(event)/
//snip

Hi there, I have an mxml component that dispatches an event. Now when
i use the component, the meta data is showing up fine. But when i
assign a handler, flex says that it is a call to a possibly undefined
method. But it is there plain as day. IDeas???
Code snippets below.
DownloadResizeEvent.as - pretty stock custom event:
package elib.event
{
import flash.events.Event;
public class DownloadResizeEvent extends Event
{
public static const DOWNLOADRESIZE_EVENT:String =
downloadresizeevent;
public function DownloadResizeEvent(type:String):void
{
super(type);
}
// Override the inherited clone() method.
override public function clone():Event {
return new DownloadResizeEvent(type);
}
}
}
now in my component.mxml:
(in a script block)
snip
import elib.event.*;
//snip
(in same script block)
snip
//located in a method
dispatchEvent( new Event(DownloadResizeEvent.DOWNLOADRESIZE_EVENT) );
//snip
Then later in my mxml
snip
mx:Metadata
[Event(name=DownloadResizeEvent,
type=elib.event.DownloadResizeEvent)]
/mx:Metadata
//snip
An now in my other mxml file that has my component.mxml called in it:
main.mxml
(in my root tag)
snip
xmlns:view=elib.view.components.*
//snip
(in a script block)
snip
import elib.event.*;
//snip
(in same script block)
snip
//event handler
private function handler_resize(evt:Event):void {
}
//snip
snip
view:componentmxml DownloadResizeEvent=handler_resize(event)/
