[flexcoders] Embedding for DataGrid
Many websites embed Flash/Flex applications for charts, but I don't see embedding for DataGrid. Given that DataGrid has many usability advantages over HTML-based pagination (my assumption), why is it not used for tables in javascript-based websites? If I am overlooking any major examples, please provide a link.

wow this seems to work but never used singleton before. jeremy, care to explain how staff works in detail? or maybe stinasius may understand what is being done here. if so please share with a flex newbie.
[flexcoders] Re: storing login data from a cfquery for use throught flex app
sorry john, i have never used singletons before either. i have a static class and would like to know how to get it store the result of the query. otherwise i have not made any progress at all. am thinking if someone can work out for me a solid flex/cf/access login(authentication) system and well commented that i can use in my projects i am prepared to pay for it.

Some of the new websites are also using HTML Canvas for charting -- Wikirank, for example -- so you'll see fewer and fewer sites using Flash just for charts as time goes by.

Try this: Create a Class that extends Image, and create another Class that extends whatever Container you're using. Give the Class to the Container as the background image. I haven't been in the Container/HaloBorder code lately, so I can't tell you specifically where to look (updateDisplayList or commitProperties would be good guesses), but you want to find the logic where the Container takes the Class that you passed in and makes an instance of it to use as a background. At that point, you want to give the instance of your Class a path to the Image. Where this approach is problematic is that the Image will not load the file instantly, so it won't be able to report its size immediately, which may cause layout issues. If you know the size of the image in advance, it's probably easiest to just hard code the image size into the extended Image. If not, you may want to preload it somewhere else and measure it.

[flexcoders] Bug/Feature request support...
I have been attempting to convince ADOBE of the wisdom of adding user defined tab loop containers for a while now. http://bugs.adobe.com/jira/browse/SDK-16897 I have gotten a few votes but for Adobe to take it seriously it needs more support from the community. Please go, take a look, and if you agree please vote for it. The item in question is the ability to define a captive tab loop for a container. Flex has the feature implemented for Popup's but you cannot define one for a panel, canvas, module, or othe containers. If you create two panels with numerous textinput boxes in each, number the tabindexes 1 through n in each, it will go from tabinex 1 in panel A to tabindex 1 in panel B, and there is no way to control that. Paul
Re: [flexcoders] Re: Hiding Swf on a website
From the HTTP Track FAQ section...
There are cases, however, that can not be (yet) handled:
* Flash sites - no full support
* Intensive Java/Javascript sites - might be bogus/incomplete
* Complex CGI with built-in redirect, and other tricks - very
complicated to handle, and therefore might cause problems
So... there are are a lot of variables to reconcile but it boils down to
what I said in the blog post. If your assets have either a relative or
absolute path sooner or later they are candidates for copy. Nay you say?
Check out he specs on Surf Offline - http://www.surfoffline.com/. The only
thing that will be well out of reach for these types of applications is
server-side scripts.

RE: [flexcoders] Re: FocusManager fun... Tab Loops redux
Paul, if you would be willing to share the screen shot of your app that you showed me, I think most would agree that the popup subsystem in Flex was designed exactly for what you want to do, and not a hack. I hope those that vote for your bug describe their scenarios that require it. Maybe the more critical feature Flex needs is an easier way to popup modules. Until we see other scenarios that require distinct tabloops that aren't MDI oriented, I don't think this issue will get sufficient priority to be addressed.

RE: [flexcoders] Styling a list item renderer
There isn't a formal way. The styleName property will be assigned the List (actually an inner content pane), but I think after it has been added to the content pane you can reset it, like in createChildren or commitProperties. Normally, all of the styles of a renderer are supplied by styles set on the List. Which styles would you want to apply to List that are different from ones you'd want to apply to the renderer?

Re: [flexcoders] Re: Embedding for DataGrid
You can certainly have a scrollbar in a JavaScript-based data grid. What's more, the scrollbar actually matches in behavior with the one you use to scroll the page -- it's the same component. So that provides a more consistent experience. Some of the reasons I know that people avoid using Flash: 1. It tends to eat focus. (i.e. you can never tab out of a Flash object) 2. It doesn't obey the user's preferences with respect to font size and color 3. It's too large -- a Flex application just for a DataGrid would be 200+ KB 4. Some users don't have Flash Player, for whatever reasons 5. They don't have Flash/Flex development skills on the team Of course, there will be cases where it's desirable to use a Flex application embedded in the web page just to show a bunch of tabular data. I'm sure they're out there. Last I remember, the Flex Developer Center on the Adobe site used to have that.

If I am overlooking any major examples, please provide a link. There are many Ajax-based data grid components out there, and they tend to be the natural choice (same environment). Some of the new websites are also using HTML Canvas for charting -- Wikirank, for example -- so you'll see fewer and fewer sites using Flash just for charts as time goes by.

Re: [flexcoders] Question from a C developper
You should check out the int, uint, and Number types. The sizes are
predefined in ActionScript 3 and not system dependent (e.g. int is
always 32-bit signed).
Operator overloading is not available. You can create an 'equals'
method and use it like so:
if (obj1.equals(obj2))
...
You can create a simple class for a structure:
public class Contact {
public var name:String;
public var address:String;
public var phone:String;
}
And afterward you can use it like so:
var contact:Contact = new Contact();
contact.name = Joe;
contact.address = Los Angeles;
addToAddressBook(contact); /* function call */
ActionScript 3 is a pass-by-value language. Everything is passed by
value. When you pass an object reference to a function, the reference
is passed by value -- i.e. the function receives its own copy of the
reference.
If you're thinking of C++ references, this is not it. Think pointers instead.
Just to be clear:
function foo(ref:Object) {
ref.prop1 = new value;
}
var obj:Object = new Object();
obj.prop1 = old value;
foo(obj); // modified
trace(obj.prop1); // prints new value
Lastly, you can convert an int to a Number by simply assigning it.
var i:int = 10;
var n:Number = i;
If you're coming straight from a C/C++ background, there's a lot
you'll need to unlearn before you start to get a hang of ActionScript
3. But it's basically in the same family of languages, so you should
have no trouble.

Hello,
I am a C developper and now I am developing in Action Script. I have
questions about ActionScript
- Is it possible to define a variable as a long ?
- How to program the overloading of an operator like the equal between 2
objects of a same class.
- What is the equivalent of a structure ?
- When I call a function with a parameter, did this parameter is modified
when I return from this function ?
- How to convert an int to a Number ?
Thank you,

[flexcoders] Interested in getting an update on Maven and Flex
Sonatype has been doing a lot of work on getting good Flex support together for Maven (and vice versa). They're holding a meetup where some of the topics will include Flex. Check out the details here: http://www.sonatype.com/people/2009/03/sonatype-maven-meetup-on-march-19th-2 0th/ Matt
Re: [flexcoders] Styling a list item renderer
Thanks for the response Alex. The styles I'm mostly talking about are very specific to the item renderer. For example, my renderer has a colored circle in it along with a few other things. I'd like to specify a radius style that can be a specific radius for one list and a different radius for a separate list. Thanks again for taking the time to participate on the list.

RE: [flexcoders] Styling a list item renderer
So if the renderer used say, a style named aaronRadius to determine the size of the circle, you don't have to change the styleName on the renderer. If you put a List selector in your styles block with aaronRadius in it, it should transfer through to the renderer. You won't be able to use aaronRadius in the mx:List tag because it isn't defined in the style MetaData, but you could pair your renderer with an AaronList subclass that defines aaronRadius on it, and makes your renderer the default renderer.
