Hi,

Why is it inside a HBox container? Take it out of the HBox container

I imagine you could implement logout differently?  I would look at
refreshing the page or navigating to a page saying you've successfully
logged out.  This could either be html or a flex page. I know its a hack for
the shared code but at least the flex session should be destroyed as the
application would be reloaded?

Its just an idea.

[flexcoders] LineSeries and fillFunction

[ukguy2k000]

Hi,

Recently I've written a custom fillFunction which I'm struggling with. Here's 
the source code:

 private function myFillFunction(element:ChartItem, 
index:Number):IFill
 {
var c:SolidColor = new SolidColor(0x00CC00);
if(index == buyIndex)
{
return c;
}  
else if(index == sellIndex || !operationIntentionBuy)
{
c.color = 0xFF;
}
return c;
}   


The buyIndex, sellIndex and operationIntentionBuy are flags which are updated 
as the users selects different chart items. The idea is to select to chart 
items (a buy item and a sell item on the chart). However, the logic doesn't 
work as I've expected. In particular, it seems that my fillFunction is only 
called initially and then the values are cached. 
Initially I thought that the function would be called every time you mouse over 
a chart item, but perhaps for performance issues, the values of the 
fillFunction are cached.
Presumably it's called only when the dataProvider is refreshed?

So my questions are:
1. When does fillFunction get actually called? Is my guess above correct?
2. How can I force my fillFunction to be called? refreshing the dataProvider?
3. Is there a better way of doing this?

Many thanks

Have a look at aSQL (http://asql.mooska.pl/). I think it is still
experimental. I have tried it once, and I was able to communicate with
mysql from both AIR and the Browser.

Hi,
My problem is simple,
In my TreeTable The ItemRenderer show me only one level.
When I click the parent it will show only the level beneath it,
although it has childrens, WHY??? 
When I use depth, I can see the tree but it doesnt activate the ItemRenderer.
How can I set the Itemrenderer to manipulate and show ALL branches?

Please advice guys, I have been looking every where but couldnt find a solution.

Re: [flexcoders] MySQL and Flex

[Brendan Meutzner]

Wesley is correct, you'll need a middle tier technology to facilitate the
communication between Flex and a backend database (ie. ColdFusion, Java,
PHP, etc...).  You would use RemoteObject, HTTPService, WebService classes
to hook up from Flex to whichever middle tier option you use.  Then you'd
use whatever ODBC, etc... options you have within the middle tier to talk to
the database.

Re: [flexcoders] MySQL and Flex

I could be wrong but as far as I know you need a server technology to talk
to the database.  You then need to communicate with your server technology.

Is this for an Air app or one to be deployed to a browser?

Is anyone using any  Java bean to action script class converter,
preferably with ANT integration? There are few out there but they are
either not being maintained or do not have ANT integration.

RE: [flexcoders] Architecting for extensibility

[Tracy Spratt]

First, the classes do not need to be "loaded".  They only need to be linked
in by the compiler.  A variable declaration typed as that object will
suffice

 

Have you looked at Modules?  This is one of the issues they were designed
for.

Subject: [flexcoders] Architecting for extensibility

 

I'm looking for some architecture advise.

My AIR application has the ability to render certain kinds of data, each of
which has a unique string descriptor (e.g. "red"). I would like to make it
easy for others to add renderers for other kinds of data. To accomplish
this, I created a renderer directory (Object) where the data descriptor is a
key to the class path for the renderer and I planned to make extensive use
of dynamic instantiation - when I ran into "red" data, I could just look up
the "red" renderer, instantiate it, etc. My thinking was that the new
developer would just need to create a renderer that implemented the requiste
interface, create an entry in the directory, and would need very minimal
understanding of the rest of the architecture to get their data to render.
But I ran into the problem described here:
http://thillerson.

wordpress.com/2007/03/01/runtime-class-instantiation-in-actionscript-30/  
If you don't want to read it all, basically you need to make sure the
referenced class has been loaded into your swf before you try to reference
it (at least, that's my understanding). So, in my directory, I created
something that creates and then destroys (for memory conservation) an
instance of each renderer, and now my directory looks something like this: 

public class RendererDirectory {

private var dir:Object { red:"com.blah.renderers.MyRenderer",
blue:"com.joedata.renderers.BlueRenderer", ...};

// to make sure everything is in .swf
private static function kluge():void {

var a:Array = [new MyRenderer(), new BlueRenderer(), ...];
a = null;

}

public function getRenderer(datakey:String):IMyInterface {

// all error checking omitted for brevity
var classPath:String = dir[datakey];
var classRef:Class = getDefinitionByName(classPath) as Class;
return new classRef();

}

} 

I'm looking for advise on whether there is a better way to accomplish my big
picture goal (ease of extensibility) or improve on my current scheme in some
way.

TIA!

make extensive use of dynamic instantiation - when I ran into "red"
data, I could just look up the "red" renderer, instantiate it, etc. My
thinking was that the new developer would just need to create a renderer
that implemented the requiste interface, create an entry in the
directory, and would need very minimal understanding of the rest of the
architecture to get their data to render. But I ran into the problem
described here:
http://thillerson.wordpress.com/2007/03/01/runtime-class-instantiation-i\
n-actionscript-30/ 

If you don't want to read it all, basically you need to make sure the
referenced class has been loaded into your swf before you try to
reference it (at least, that's my understanding). So, in my directory, I
created something that creates and then destroys (for memory
conservation) an instance of each renderer, and now my directory looks
something like this:

public class RendererDirectory {
private var dir:Object { red:"com.blah.renderers.MyRenderer",
blue:"com.joedata.renderers.BlueRenderer", ...};
// to make sure everything is in .swf
private static function kluge():void {
var a:Array = [new MyRenderer(), new BlueRenderer(), ...];
a = null;
}
public function getRenderer(datakey:String):IMyInterface {
// all error checking omitted for brevity
var classPath:String = dir[datakey];
var classRef:Class = getDefinitionByName(classPath) as Class;
return new classRef();
}
}

I'm looking for advise on whether there is a better way to accomplish my
big picture goal (ease of extensibility) or improve on my current scheme
in some way.

TIA!
