Re: [flexcoders] Bindable metadata tag event name
Either I'm not following, or you have something else wrong.
If a model object (or the MXML component itself) has a property with custom
getter and setter as I showed, you can most certainly say
mx:Text text = {model.txt}/
or
mx:Text text = {this.txt} /
Of course I'm referring to one-way binding - I have not yet played with
binding in Flex 4.

I've always used plain bindable tags but I'd like to know whether I can
achieve the same auto-updation functionality when it comes to using
bindable
tags with custom events.

Hi folks,
The Bindable metadata tag allows an optional event name to be specified
which would be event name that would be dispatched when the property in
consideration changes. I've read somewhere that specifying a distinct
event
name for each bindable property reduces the performance overhead (less
work
for BindingUtils or so it seems, I can't seem to find the actual
implementation detail). But this doesn't work with bindable properties
when
used with flex controls. For e.g. this *works*
mx:Script
[Bindable]
private var txt:String = HI;
private function onCreationCompleteDone(event:Event):void
{
txt = Changed text!;
}
/mx:Script
mx:Text text={txt} /
This doesn't (notice the event name specified):
mx:Script
[Bindable(myEvent)]
private var txt:String = HI;
private function onCreationCompleteDone(event:Event):void
{
txt = Changed text!; // Never called!
}
/mx:Script
mx:Text text={txt} /
I did try analyzing the autogenerated AS files; the ones generated when
I
use simple [Bindable] is pretty easy to understand since it generates
plain
getter and setter for the `txt` property but when I use
[Bindable(someEvent)], the code generated is a bit cryptic with the
stuff
with Watchers and all that.
Would someone be kind enough to shed some light on this matter? How this
all
this Bindable stuff work under the hood?
TIA,
sasuke

[flexcoders] Swapping custom components within Viewstack Navigation container...
Dear Group,
Somewhat of a newbie and trying to do something that I think should be
possible. I have my application below, that when I press a button in the
viewstack it changes the Skinnable container stuff within the given
navigation container to my custom component defined. So that works well. What I
want to be able to do is within my custom component, I want to change the
stuff again in the navigation container based on a button within the custom
component to another custom component. To clarify I want to swap out custom
component A with custom component B.
Is there a way so that I can define a variable that is used instead of naming
the component as in this snippet:
s:NavigatorContent label=Clients
icon=@Embed(source='/assets/png/32x32/globe.png') width=100% height=100%
id=Information
s:SkinnableContainer width=100% height=100%
MyComps1:ClientsMain/
/s:SkinnableContainer
/s:NavigatorContent
Rather do this:
s:NavigatorContent label=Clients
icon=@Embed(source='/assets/png/32x32/globe.png') width=100% height=100%
id=Information
s:SkinnableContainer width=100% height=100%
MyComps1:somekindavariabledefined/
/s:SkinnableContainer
/s:NavigatorContent
Then based on the click of another button it changes the value of the variable?
s:Button x=105 y=111 label=Main Configuration width=148
height=31 click=changecomponentvariableA /
s:Button x=106 y=206 label=Main Reports width=148 height=29

[flexcoders] Printing without the pop-up window...
Is there a way to get a Flex program to send a print-job to the default printer without it popping up that window where you select the printer and click the print button? I'd really like to be able to do that. Is that even a function of Flash-player? Or is that built-in to the browser? Would there maybe be a java-script I could use to disable that pop-up in the browser? Thanks, Laurence MacNeill Mableton, Georgia, USA

Re: [flexcoders] Re: Thoughts on Flash by Steve Jobs
Jeez...it's *three* devices, and you *do* have a choice... You're annoyed because you're being shut out of a market you want to be in, but your arguments as to why you should be allowed into that market are specious. If you buy an iPod/Pad/Phone, you buy it as is, knowing what it can and can't do. It can't do Flash. If you don't like that, don't buy the device, it's really very simple. If you want to hack it to make it capable of running Flash, then sure, go ahead, no-one is going to sue you. You might not be able to claim on your warranty or update the OS once you do that but, yes, it's your choice if you want to go that way. Most people don't because most people can actually live without Flash, believe it or not. If you want to develop for the iP*, then learn objective C or use HTML5/Javascript. If you don't then don't. Again, it's a simple choice you can make. Technologies change, sometimes their fortunes rise and sometimes they fall. Flash has been the undisputed winner in the RIA wars up till now. Jobs is betting the future of the iP* platform on HTML5. Maybe he's wrong about it, but maybe he isn't. Time will tell.

[flexcoders] trace address of a object

Re: [flexcoders] Re: Thoughts on Flash by Steve Jobs
mitek17 Yeah, I know that... well, I didn't say it's usable for commercial purposes. That's true it isn't. What I said is that, if it would matter more to Adobe these project exist and continue to develop, it would be better, for the image at least. Well, you know, MS doesn't really support MoonLite or Mono, but it kind of mentions it everywhere, and, well, to be honest, I don't know what the exact status of their relationship is :) But, they aren't fighting, or, at least so it seems :) I mean, that's great and most welcomed that Adobe have OSS initiatives, but, there are some times, when you know there's an error in the built-in classes - the most obvious are the one in the Sound constructor and ExternalInterface serialization routines - you can even see the damn thing in the playerglobals.swc, but you cannot help it's being there... I don't know how much of engineering powers are dedicated to the Linux version of FP for example, but, it sounds like not to much, and it also looks like they don't really communicate with the rest of the Linux community... and, to be honest, the Linux Flash Player made by Adobe is... well, if Mac users had that, I would side with Steven Jobs admirers in this topic :D It is truly the most buggy software I've got so far in my installation :) (right now for w/e reason it doesn't display any serif fonts at all for eg.) I hope the remark about flash.* sources wasn't sarcastic, I really believe that would help. Not that I know of any initiative of writing an alternative Flash Player (I'm not sure GNash is alive yet - one thing true - apt-get finds it so far), but, technically, that would made the language an OSS one. But, again, that must be some commercial concern, of which I don't have enough knowledge to say any more. Best. Oleg

It just really angers me if I were to own a device and some entity somewhere tells me I cannot run my own software on it. I would be ranting against MS or Linux just as angrily, if they were to suddenly come out and say I couldn't run a particular piece of software just because they don't like it anymore. (And, yes I read that article where MS says that HTML5 is the 'future of the internet.' They said nothing about removing Flash support from Microsoft Windows in that article.

Before old Steve-o came out against Flash, I could write one program that would work on Windows, Linux, and Mac.

Maybe he's wrong about it, but maybe he isn't. Time will tell. Yes, technologies do change -- but it should be the free market that determines which technologies survive and which don't, not some ivory-tower egghead who determines by fiat what's best for everyone. THAT'S why I called Steve Jobs a bastard. Perhaps I should've said elitist bastard to make it clearer. I truly DESPISE it when ONE person has the power to mess up things in my life. If everyone decided ON THEIR OWN to stop using Adobe Flash, that would be a completely different story -- the majority would have spoken, and I could more easily accept the outcome. But Jobs is simply deciding that he knows best, and we're going to all follow him because he's so damn smart. THAT is not the free market!

Re: [flexcoders] OAuth and AIR
I think this ends up being kind of a philosophical debate with no right answer. I agree with you that the ideal solution is the external web browser loading the provider's page so that the user never types their credentials into a site or window that isn't the one that belongs to the service. But because these are AIR applications and they're already running in a trusted environment, it seems like the user already trusts the application not to do anything harmful and so from a UX standpoint, just using AIR's HTML component is a better solution.
