Re: [flexcoders] Button with Icon and two labels one with Left align while Other with right Align

label2Field.text = label2;
// align
label2Field.x = 100;
label2Field.y = 5;
// bring to front
setChildIndex(label2Field, numChildren - 1);
}
}
}
Notice the implementations of the createChildren, commitProperties,
measure, and updateDisplayList methods, the label2 setter, and the
backing variables _label2 and label2Changed, and the internal
TextField object label2Field, and how they're all handled. You'll find

[flexcoders] Lua Alchemy v0.1a Released
Lua Alchemy is a port of the Lua programming language for ActionScript using Alchemy. Using v0.1a inside Flash/Flex you can create any ActionScript class available at runtime, call functions, get/set properties on ActionScript objects and use Lua functions as an ActionScript function (including event listeners). The project can be found here: http://code.google.com/p/lua-alchemy/ A demo can be found here: http://www.arcanearcade.com/Flex/LuaAlchemyDemoV.1a/index.html The next version will include syntax sugar so instead of calling as3.call(var, function, param) you could call var.function(param) and similar calls to make calling ActionScript code look the same as calling Lua code.

[flexcoders] Re: Write file to server
Mike
You need to send your data to some kind of server side code (Eg. PHP).
From your code, you are sending data to a text file. A text file has
no idea what to do with the data you are sending it (Actually, the
text file doesn't even see the data - text files are very
unintelligent as files go) so does nothing. Your code does exactly
what you told it to. It made the request to load the file. Once the
request is made the complete event fires and you get your message.
What you need is some form of server to run code on. What server do
you have?

I think you're misunderstanding how event handling works. You can't
set up a result handler on an rpc call and then set some other
variable to the result of the function and think that when the result
handler gets called it will somehow return a value to where it was
called by some other code.
Try something like this:
ProjectGateway.as
package com.isavepets.projects
{
import mx.collections.ArrayCollection;
import mx.controls.Alert;
import mx.rpc.events.FaultEvent;
import mx.rpc.remoting.Operation;
import mx.rpc.remoting.RemoteObject;
public class ProjectGateway
{
private var _ro:RemoteObject=new RemoteObject();
public function ProjectGateway()
{
var RO:RemoteObject = new RemoteObject();
_ro.destination = ColdFusion;
_ro.source = com.isavepets.projects.projectGateway;
}
public function execute():ArrayCollection{
var token = _ro.list();
var ac=new ArrayCollection();
token.addResponder(list, faultHandler);
token.ac=ac;
return ac;
}
public function list():void{
e.token.ac.source=e.result as Array;
}
private function faultHandler(e:FaultEvent):void {
Alert.show(e.fault.message, 'Project Gateway Error');
}
}
}
Then:
mx:Script
![CDATA[
import mx.collections.ArrayCollection;
import com.isavepets.projects.ProjectGateway;
import mx.events.CollectionEvent;
[Bindable]
public var projectData:ArrayCollection;
public var ProjGateway:ProjectGateway = new ProjectGateway();;
public function initApp():void {
projectData = ProjGateway.execute();
projectData.addEventListener(CollectionEvent.COLLECTION_CHANGE,
onLoad);
}
private function onLoad():void{
//your data is ready to go

[flexcoders] mailto from textarea in AIR application - line breaks fail in windows
I have an AIR app that needs to open and pre-populate an email in the user's
default email
application. This is not difficult, see the application code I've provided at
the end of this
post.
When you build this AIR app and run it on a mac, it works fine - any carriage
returns you
typed in the text area are displayed properly in apple mail and other mac email
clients.
When you build this AIR app and run it on a pc, it fails. Only the text before
the first
carriage return is displayed.
I have tried the following:

2. replacing new lines in the text (\n) with a windows return and new line

[flexcoders] how to manage display of 2 images inside a VBox?
Hi Flex Coders The situation: a large photo jpg and a small text png are vertically constrained within a VBox. The small text png is positioned below the photo in the layout. The problem is the small file loads first at the top of the VBox and then is pushed down to its place at the bottom once the larger photo loads. So how to program Flex to load the text file after the photo file? Or second choice would be for the text file to be constrained to load in its place. Putting this within the opening VBox tag didn't work: creationPolicy=queued creationIndex=0 Thanks in advance for any help. Kearney Buskirk

[flexcoders] Re: Flex 3 checkbox as itemrenderer in datagrid, selected property boolean not working
I may be wrong (Someone correct me if I am)...
The built-in item renderer sees the field as a string and decides that
an empty string will be false and non-empty will be true for the
checkbox. It does not convert the string value of false to the
boolean value of false.
You will need to create a custom item renderer for that field.
See http://blogs.adobe.com/aharui/item_renderers/ for details.

Hi Keith
Thanks for the response. Yes, I tried:

the contents
of all the text, but on a single line, i.e, without any carriage returns. So
one step closer,

typed in the text area are displayed properly in apple mail and other mac
email clients.
When you build this AIR app and run it on a pc, it fails. Only the text
before the first
carriage return is displayed.
I have tried the following:
1. forcing word wrapping in the text area
2. replacing new lines in the text (\n) with a windows return and new line
(\r\n) using
this regular expression: /\r\n/gm;
Any ideas or suggestions would be greatly appreciated!

See if this works:

Basically childIndex gives you the current index, parent gives you the

[flexcoders] Creating UTF8 strings from hex bytes encoded as text
I have a need to take a string that is encoded as hex bytes and decode it into a utf8 string. For example: 30 30 30 would be 000 This works fine since chars 0x7f are standard ascii in utf8. The problem is taking this concept and trying to decode a utf8 string with bytes 0x7f. For example, the sequence: e8 8b b1 e8 aa 9e should display two Japanese characters. I do not know how to create a string with these values that will display properly as utf8. One problem is that I do not know how Flex internally stores utf8 strings. If I cut-and-paste the actual utf8 string from a file into Flex, the JA characters show up fine in the editor, debugger and the application. [I am not sure if this will show up for you but let's try] public var test:String=#33521;#35486;; So clearly Flex can understand a sequence of bytes in a String object as utf8. But how to create it? If I try to create a string using the bytes, it fails. For example public var test2:String=\xe8\x8b\xb1\xe8\xaa\x9e; does not display properly. If I view these to vars in the debugger. the test var is correct, whereas the test2 is junk. I have not experimented with the ByteArray class, as I know there are some utf8 specific functions, but why won't this work? The MX file is encoded as utf8, and as I said Flex understands utf8 strings just fine so why can't I take each byte value and concatenate to get a utf8 string?
[flexcoders] Re: mailto from textarea in AIR application - line breaks fail in windows
Manish When I use escape() or encodeURIComponent I get the same results.

The problem here is that the initialize event is dispatched _much
later_ in the cycle, so your allowDomain call never actually happens
-- you get an error before that. If you can find a way to call
allowDomain inside your module before it is intialized, this can work.
I don't think there's a way though: normally you'd call allowDomain in
the module's constructor, but there's no constructor here.
Even if you succeeded in calling allowDomain with a *, you would be
opening up a potential security hole in your app. So I would go with
Alex's suggestion and try loading off the same host.

I'll reply to you and my own post, as the solution was indeed the ByteArray class.

Concatenating the bytes is exactly what you're doing with ByteArray. You stuff the bytes into a single array and then read the entire array as a UTF-8 string. The String class does not do UTF-8 encoding/decoding itself, or you would be able to just stuff the data directly into a String object and print it out afterwards. -- http://manishjethani.com/
