[flexcoders] How to turn a dynamically loaded swf into a popup quick?
I have a swf that I am loading in via SWFLoader and I would like to treat it like a regular popup (like the ones created via createPopUp), is that possible to do with PopUpManager? What's the alternative in order to achieve what PopUpManager achieves (ability to set modal/non-modal, bring to front, ability to move dialog around, etc.) without writing a ton of code? - boon

To: flexcoders@yahoogroups.com Date: Friday, September 19, 2008, 11:08 AM Hi, Couldn't you just create a subclass of say TitleWindow and make the SWF loader a single child. Maybe write a couple public methods to interface through the window to load your content. Then use the PopUpManager to popup that subclass that holds the SWFLoader. A thought, don't know the security issues though.

[flexcoders] createPopUp and addPopUp, which one to love?
What's the process/criteria in deciding whether to use createPopUp vs addPopUp? They seem interchangeable. What is it that you can do with one that you can't do with the other? Which one do you use the most? [-] The doc says: You can use the addPopUp() method of the PopUpManager to create a pop-up window without defining a custom component. Can't you do that with createPopUp as well? [-] The doc also says ...Using the addPopUp() method may be preferable to using the createPopUp() method if you have to pop up a simple dialog box that is never reused elsewhere. However, it is not the best coding practice if the pop-up is complex or cannot be reused elsewhere... It doesn't really explain why it's not the best practice if the pop-up is complex or cannot be reused elsewhere. To me it seems to be more convenient to use addPopUp because I can do whatever I want to the dialog instance before I pass it to addPopup( ) but that's more theorizing than from actual field experience. - boon
[flexcoders] turn horizontalScrollPolicy and verticalScrollPolicy off for all
Hi, Is there a quick way to turn off horizontalScrollPolicy / verticalScrollPolicy or prevent them from showing up once and for all for all containers in an app without resorting to patching? - boon
RE: [flexcoders] turn horizontalScrollPolicy and verticalScrollPolicy off for all
It's kinda a pain to have to subclass every single container used in the app just to turn the policy to off. I was hoping that for policy-based stuff we have an app-wide setting, like Application.application.scrollPolicy = no that can be overrided by individual containers. Lazy programmers like me in this case will probably resort to monkey patching the banana containers... - boon --- On Mon, 9/8/08, Gordon Smith [EMAIL PROTECTED] wrote: From: Gordon Smith [EMAIL PROTECTED] Subject: RE: [flexcoders] turn horizontalScrollPolicy and verticalScrollPolicy off for all To: flexcoders@yahoogroups.com flexcoders@yahoogroups.com Date: Monday, September 8, 2008, 5:35 PM Subclass the containers to set the policies to off and use the subclasses instead.

[flexcoders] Donkey patching UIMovieClip subclass...
Hi, I just started using the Flex Component Kit so I am probably not doing it right. If I have a symbol that's linked to a UIMovieClip subclass in my Flex project, and if the class uses any Flex framework stuff, Flash would refuse to publish my FLA skin file. This makes sense since the Flex framework is not in Flash's classpath. To get around things I also made my Flash point to another classpath set up specifically to placate the Flash compiler, in it I have a dummy version of the UIMovieClip subclass that doesn't refer to any Flex framework stuff at all. Of course the real Flex code is still using the actual UIMovieClip subclass that does everything. It's a little dumb, hence donkey patching (as opposed to the smarter monkey). Is there anything I should be doing instead? - boon
[flexcoders] Exit effect for popup when being removed
Hi, What's the best way to have a popup menu play an exit effect when it is about to be removed by PopUpManager.removePopUp? Should we play the effect first (say dissolve or wipe up), then on effect end call removePopUp, or is there a more direct / simpler way? - boon
Re: [flexcoders] Exit effect for popup when being removed
Sorry, forgot to mention, the effects exit code has to be in a method body of actionscript code (as in effect.play( ), .etc.) when the popup is being removed, instead of just associating an effect instance with the removedEfffect style. I have tried listening to FlexEvent.REMOVED and run the exit effect handler there but that doesn't seem to work. - boon --- On Tue, 8/26/08, Boon Chew [EMAIL PROTECTED] wrote: From: Boon Chew [EMAIL PROTECTED] Subject: [flexcoders] Exit effect for popup when being removed To: flexcoders@yahoogroups.com Date: Tuesday, August 26, 2008, 6:11 PM Hi, What's the best way to have a popup menu play an exit effect when it is about to be removed by PopUpManager. removePopUp?

[flexcoders] Does ASVM JIT compiler get rid of empty functions?
Does anyone know if the Actionscript Virtual Machine JIT compiler removes calls to functions with empty body?

Will the code still incur the cost of invoking the assert function even though it's empty? - boon
[flexcoders] Large XML /w E4X vs. serialized objects /w tree traversal
Hi, I am building an app that deals with a fair bit of people relationship data coming down as XML, so the hierarchical nature of XML actually comes in handy here. I have a few options: one is to serialize each person XML node into an object, and setup the appropriate data structure for hierarchical data traversal (e.g. rooted tree). Another option is to keep everything in memory as XML and accessed the node data via E4X. The third option is to take a hybrid approach, won't consider this route right now unless this appears to be the best. My concern is that instantiating thousands of objects will create a performance issue (happened at another project that dealt with thousands of dto's), not to mention it's very slow to instantiate lots of objects. At the same time, I am not sure how fast E4X is at dealing with large XML. Which approach would you take? Which one is likely to scale better? Large in-memory XML + E4X traversal or data structure with lots of objects + algorthmic tree traversal? - boon
Re: [flexcoders] Re: Large XML /w E4X vs. serialized objects /w tree traversal
Thanks Florian. Problem is the performance actually degrades quite a bit when there are a lot of objects in memory. Instantiating a lot of objects is dog slow as well. Also, there would really be no dependency with the datasource even if we go XML (assuming this is the best option) because either way we have to write code to process/transform the incoming data, in this case it would be just code that transforms whatever format it comes in as into XML. There is also no need for events in this case as well since they are plain vanilla data objects with only public properties in it. - boon --- On Sun, 8/3/08, florian.salihovic [EMAIL PROTECTED] wrote: From: florian.salihovic [EMAIL PROTECTED] Subject: [flexcoders] Re: Large XML /w E4X vs. serialized objects /w tree traversal To: flexcoders@yahoogroups.com Date: Sunday, August 3, 2008, 12:53 AM I would choose the class hierachy approach. Write your own classes for relationships, people etc. The pros of this approach: * You do not depend on a datasource: it does not matter where the data comes from ((different) XML sources, remoting [,...]). * You have strong typed objects and you can embed your own events and errors. This means (unit-) testing becomes more effective. The cons: * You have to implement a parser.

RE: [flexcoders] When not to use weak references?
it's listening to is still around though right? Weak reference or no? -Josh On Tue, Jul 15, 2008 at 2:43 PM, Tim Rowe [EMAIL PROTECTED] com.au wrote: Use strong references when you're adding an event listener to the same instance dispatching an event. If it's an anonymous function, you need to use a strong reference. Also, use strong references when you want speed – weak references are slower. Always use weak references when dealing with singletons (Cairngorm's event dispatcher is a singleton, hence, always use with Cairngorm), or objects that live the life of the application. This includes timers waiting on call backs also. Not always true but if you have an object you intend to never have destroyed, but it may also be perfectly safe to use strong references. Keep in mind though that using a weak reference on, say, an event listener where a strong one was required may result in things like that listener not getting called.

RE: [flexcoders] In actionscript, converting from string to number loses precision
This actually exists in Flash 8 as well.

Can you please file it?Apparently when the AS3 compiler compiles trace(i - 952.86), it doesn't convert the 952.86 to the exact same Number that the player does when it executes parseFloat() on "952.86". They should produce identical Numbers, and the different should be exactly 0.You should be aware, however, that the Number they produce will be very close but not exactly equal to decimal 952.86. The reason is that Number stores values as binary fractions, not decimal fractions. A decimal fraction like 0.375 has a terminating binary representation (0.011 =0 x 1/2 + 1 x 1/4 + 1 x 1/8) but a decimal fraction like 952.86 has a non-terminating binary representation that would require an infinite number of bits to represent exactly. This is why an _expression_ like 0.1 + 0.2 == 0.3 evaluates to false! This is NOT a bug, it's a consequence that microprocessors and computer languages tend to do floating-point arithmetic in binary, not in decimal. The Number type in AS3 is the same as the 'double' type in Java and C++, which have the same issue.- GordonFrom: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Boon Chew Sent: Wednesday, March 08, 2006 9:31 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] In actionscript, converting from string to number loses precisionAnyone has any idea why it's not possible to convert a string to a number without losing precision?var s:String = "952.86"; var i:Number = parseFloat(s); trace(i); trace(i - 952.86); // Not zero! - boon Yahoo!
