Flex :: Writing A Custom CompareFunction?
Sep 2, 2009
I am sorting an XMLListCollection in alphabetical order. I have one issue though. If the value is "ALL" I want it to be first in the list. In most cases this happens already but values that are numbers are being sorted before "ALL". I want "ALL" to always be the first selection in my dataProvider and then the rest alphabetical.So I am trying to write my own sort function. Is there a way I can check if one of the values is all, and if not tell it to do the regular compare on the values?[code]

I have a ClipDragger class where event listeners (MOUSE_DOWN and MOUSE_UP) are added to any MovieClip I choose, which fires methods that invoke startDrag and stopDrag. This is great whenever drag and drop is all I need, but say I want to add an action to the MOUSE_DOWN function/method (for instance play an animation inside a movieclip) and add an extra event listener (MOUSE_MOVE).writing a new custom class?

I am currently working on the 'Flash.utils.ByteArrays' and I am using writeobject() and readobject() to write and read byte Array objects. I also understand that, the objects are serialized and de-serialized as byte arrays through AMF formatting.
Since I am trying to write the object to a device(credit card reader) that doesn't supports AMF, I was wondering if there is any other way where I can still use the writeobject() and readobject() methods but can control the creation or reading through other 'byte array ' serializing and de-serializing format options if any.

I'm going to write a custom multimedia player. It will be embedded into a web-browser and will receive data from a server over SSL connection.
Required functionality is: MPEG4 video and different VoIP audio decoding (e.g. G.711 or G.729) custom controls waveform representation (or just flexible drawing API) I think about Adobe Flash (or Flex). But I know little about this technology. My biggest concern is multimedia decoding.
Can you recommend Adobe Flex or anything else for this project? What pitfalls can I expect on this way?

This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event
package events
{
import flash.events.Event;
import ui.map.MapElement;

The spark panel component for example can be written like this
<Panel title="Skinny">
<child components ... />
<controlBarGroup>
<child control bar components ... />
</controlBarGroup>
[Code]...
The motivation here is that I can now create a couple different skin files to change the look and layout of those subgroups. Reading source of the spark panel, there are some calls within the mx_internal namespace such as getMXMLContent() which is a method of the spark group component, but which I have no access to.
Does the description above make sense? How can I create custom 'contentGroups' in my custom Flex4 component that can use nested mxml child components? Should I approach this a different way?

whatever you wan't to call it. Nevertheless, curious to know if Air can write inside it's own installed package. I'm referring to the OSX '.app' files found in great numbers in the applications folder. Since every one of these can be opened as a regular folder, i'm guessing that's what they are.
What other fancy filewriting tricks am i missing out on?

Ive been doing some research and I cant seem to find anything on writing to a file. My initial question was writing a array to a seperate file. But now I am looking for resources on how to write any data such as XML or a array to a file. What I want to do is create a game editor. I want to eventually save that data to a file to be opened later.

I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.

I am faced with a dilemma. I am writing components with nested components. What sort of coordinate system scheme should I implement? I want to be able to pass points to the components without having to worry about where the origin is in absolute terms. At the same time, I want to have some sort of encapsulation when it comes to origins and stuff. Is there any sort of guideline to follow when it comes to nested components and such?

I couldn't work it out yet...
package components {
public class templateSelection extends VBox {
static public var tempSelectionBag:Dictionary;
[Code]....
I want to have a custom class tempSelection with a Dictionary as a public accessable property of that class. If I use this code, the compiler tells me:
1046: Typ wurde nicht gefunden oder war keine Kompilierungszeit- onstante:Dictionary
Which translates to:
Type was not found or was not a compile-time constant: Dictionary

I have a custom Flex 4.5 component (to be used in a List) -
Game.mxml (represents a clickable playing table in a card game):
<?xml version="1.0" encoding="utf-8"?>

But I never see the "game clicked: " trace. Does anybody please know why? I'm probably missing something minor, because I can see the "Clicked: 8946" trace.

This is similar to the question asked here. I am dispatching custom event "ShopEvent" but i am getting error "Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent"Note: Error is thrown from the parent custom component (3rd code snippet), I have added more details thereThis is my custom event. See the first constant, I copy pasted the event name in custom components.

This is a bit of a crazy question, but does anyone out there know how to go about writing an extra compile step into the flex compiler. The idea would be that the MXML compiler would knock out the MXML to AS3 code as it does, but we have an extra step between the AS3 code and the bytecode.
The reason why I ask, is that this would be a great step to handle things like metadata tags to make code changes. A common practice in a lot of frameworks is to have an [Inject] tag before a variable. I.e. [Inject] public var user:IUser.

There are many dynamic languages that target Sun's JVM (Groovy, Scala, Jython, Jruby etc) and I was sure there are many that target Adobe's AVM as well. But I was surprised to find only haXe do something similiar. related question on this site
I think the eclipse e4 SWT project doesn't compile to ABC (ActionScript Byte Code) directly, but first converts Java to AS3 and then the Flex compilter does the rest.Could it be that no one yet wrote a simple Java / Python / Scala AVM2 compiler that can be used as an alternative to the proprietary Adobe Flash Builder (formerly Flex Builder)?I don't mind paying Adobe for a fine producy, but writing Java in eclipse is so much faster and convinent than the half baked adobe plugin suite. are there really no efforts other than haXe?

ow do you display HTML formatted text in a Spark custom item renderer (Actionscript)?
Sample Code:
The html content in item.post_content displays as plain text in the IconItemRenderer messageFunction snippet below (which is just the default generated code for Icon Item renderer):
<s:itemRenderer>
<fx:Component>
<s:IconItemRenderer iconField="iconField"
iconWidth="64" iconHeight="64" labelField="post_title" messageFunction="getPost">

I have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.

I made a custom server that accepts TCP connections on a certain port. I made a corresponding client that sends data to the server. The client writes to the socket and the server seems to accept it. In short, the server / client rig works. Now I want to re-create the client only this time, via Flex 4 / Flash Builder 4. How do I go about making my Flex 4 app connect to my custom server?
[code]...
With that type of approach, the server doesn't seem to be receiving any connections at all. And also, even though I set the requestTimeout to 5, my Flex app seems to continuously try to connect to the server because I rigged it so that the button when clicked will call this HTTPService also that certain button would get disabled and it will get enabled again after it the connection successfully connects, returned an error or if it timed out.
So with all these said, I want to ask you, what is the best approach to making my Flex app connect to my custom made server?

Here are the strings this array can contain (in the correct order):
'recipients,' 'columnSelector,' 'headerImageLink,' 'title,' 'mainText,' 'text,' 'bodyImage'
Now, to sort them, I obviously don't want to do something like this:
if( a == 'columnSelector' && b == 'headerImageLink' ) return -1;
else if( a == 'columnSelector' && b == 'title' ) return -1;
else if( a == 'columnSelector' && b == 'mainText' ) return -1;
So that brings up an interesting thing. I know you can optimize the above some using something like this:
if( a == 'columnSelector' || a == 'bodyImage' ) return -1;
This would get the last two, but lately I have just wanted community input on issues I have had in the past. So the question is, what is the best way to write a custom sort, using a relatively random order (not alphabetical, etc)?

I am using a custom component at the top of my application that includes an image and a buttonBar. I have the namespace declared in main.mxml as comps and the package is components. When I assign the dataProvider to the buttonBar and run the application, all I get is a blank page. If I remove the dataProvider everything loads fine. the dataProvider is supposed to be the ViewStack component I have in the main.mxml. The buttonBar and image custom component is TopNav.mxml
The problem is that my TopNav component does not know the dataProvider I am asking it to change; MyViewStack. Do I need to create a public viewstack variable and pass it to the component?
