Subject: [flexcoders] Italics in datagrid cell
Hi - I'm trying to display italics in a datagrid cell based on certain
row criteria. I've created a custom itemRenderer in AS3 that derives
from UIComponent and that contains a UITextField as a child. (This
might seem a little over-complex for what I'm describing, but I have
other use for doing it this way... :-))
I override commitProperties and do the following:
override protected function commitProperties():void
{
super.commitProperties();
textField.text = ... // get text value from data (works okay)
if (data data is MyClass MyClass(data).notAvailable)
{
textField.textColor = textField.getStyle(disabledColor);
textField.setStyle(fontStyle, italic);
}
else
{
textField.textColor = textField.getStyle(color);
textField.setStyle(fontStyle, normal);
}
}
The result is that I *do* get the disabled color when appropriate, but
I *don't* get the italics.
Does anyone have any idea what's going on? Thanks in advance for your
help!

[flexcoders] Uploading file to a java servlet.
Hi everyone, I'm wondering if anyone has actually write a servlet that becomes the URL target of a FileReference.upload() method. It seems that the uploaded file can be retrieved in the inputstream of the post request, i.e. in the inputstream of the Request in doPost() method. The problem is, there are lots of other data as well in that input stream (the actual file uploaded is in a form value called Filedata) and I don't know how to extract just the uploaded file so that I can store it in the machine where the servlet is. I tried using getParameter(Filedata) but it doesn't work. Does anyone know how to get around this problem? Many thanks in advance. Any help would be greatly appreciated. Cheers, Ivan.
[flexcoders] Graphical elements in a Flex dynamic list
Hello, I'm using SOAP services that generate XML result. I need to feed a Flex dynamic list with the XML result. I try to use the XMLCollection AS object and I display it in a DataGrid. But I've got some problems. I just need to insert graphical elements (ex: MXML checkbox) into the list. Example: - The first column is a checkbox (for selection of the line) - The second is the `name' column - Third is `date' -- |Select | Name | Date -- |X | Justin| 01/12/07 | | Martin| 01/15/07 |X | John | 01/17/07 -- I found a solution: - I create another MXML file with the checkbox and I insert it into the list With this solution I can't change the state of the checkbox (true or false) because I can't access to it with AS because it's in another file. There is another problem: when I scroll the list, the checkbox state is reinitialized (with the MXML state = 'false') and I can't check all the lines together. Have you got another solution? Thanks

[flexcoders] Structure and visual design techniques
I've been the reading helps docs and I've come to the conclution that the suggested technique for using graphical and animated elements in flex is render then using actionscript. This is all well and good, but I come from a Flash as 1.0 and 2.0 background, I'm used to having these graphical elements on the stage nested in MovieClips where I can easily access and edit them and visualy see the structure(tree if you like) of the swf. This also enables me to swap layers easily, move MovieClips up and down the tree, generate new MovieClip from graphics drawn in the IDE, all visualy! It seems to me that to develop heavily using actionscript in flex, it requires a lot of thought and design about the structre of the swf to be undertaken before actually coding anything. so.. I was just wondering what techniques etc people are using for this type of visualisation. Cheers Si

Did you mean Executing application? You want to create new components on the fly as your app runs? Have you looked into AddChild? You can create visual components via ActionScript and and add them to a container using AddChild. You can even use the top level application as the container, so the 'start' state could have no components displayed. Additionally, you may want to look at the PopUpManager class.

[flexcoders] Implementing a CheckBox array..
I posted this as a reply in one of my other questions, so I apologize in
advance if I appear to be spamming things. I've modified the question,
anyway.

Hey all.. I just have a question about forms in FLEX 2:
I've got a repeater populated by a list of musicians taken from an XML
file. Each artist is represented by a checkbox and when a submit button
is clicked, I want that array to be sent over to a php script.
This is the vbox containing the artist info and checkbox:
mx:VBox
mx:Text text={artistRepeat.currentItem.name} /
mx:Image source =
{artistRepeat.currentItem.image} scaleContent=true /
mx:CheckBox data={artistRepeat.currentItem.name} id=cBox
click=modifyArray(Object) /
mx:Text text={cBox.data} /
/mx:VBox
And the function for handling this is:
public function modifyArray(item:Object):String{
if(cBox.data != null){
return artistlist.text;
}
return artistlist.text = (artist = +cBox.data+);;
}
This registers the artist as 'undefined'. Am I going the right direction
here?
Thanks,
Tom.
Again, i'm sorry if im being repetitive here.

Re: [flexcoders] open source plug-in AS frame work ?
I bet he means 'plugins' like some web apps are starting to have.
I think your answer is; You need to create a framework that has a public
interface API. Once this api is set you can load any component/module at
runtime and share within the specified ApplicationDomain.
I am working on something similar for future projects and components of
mine. But, making use of good interfaces is one way to start this without
any destination in mind.
IE
IStyleClient.
I could load a module at runtime and check it with
if (module is IStyleClient)
style = IStyleClient(module).getStyle('blah');
That is the simple point. One other thing you need is a map or start up
expectation of what the app can handle. This means what interfaces the app
is going to use. A little more complicated but, I am sure in the next 2
years this will become like a 'myspace' fad in Flex. Pretty sure and mark my
words on this one. :)
Peace, Mike

Just do it the same way you did it in AS2. In your code you are

don't assign the value to a local variable. If you did that in the
AS2 code,
you'd end up with the same issue.
Also, instead of removing the submenuitems as you did in AS2, just
remove
the items from the display list. That way you don't have to create and
destroy the items everytime. You can create them once, and then add
them or
remove them from the display list. It should make the process faster,
especially if you're using getDefinitionByName.
By the way, if you're know the class name in the function that you
are using
getDefinitionByName and instantiating the class, why not just
instantiate
the class? As in:
import FlashClasses.MenuItem;
...
[in your loop]
var instance:MenuItem = this[nomeMenu+j] = new MenuItem();

then how do i reference to those instances of the class MenuItem if

with attachmovie i had a different reference to each one of the

[flexcoders] Correct way to determine MP3 length in ms and determine when sound starts playi?
