I have very simple Flex Air application where I'd like to load image from documents directory:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" creationComplete="init(event)">
<fx:Script>
<![CDATA[
import mx.events.FlexEvent;
protected function init(event:FlexEvent):void {
image.source = File.documentsDirectory.resolvePath('image.jpg').nativePath;
}
]]>
</fx:Script>
<s:BitmapImage id="image"/>
</s:WindowedApplication>
The problem is that Flex Air doesn't know how to handle native (absolute) path.
Looks very easy, but I don't know how to solve it...
You need a URL (or a ByteArray) to load an non-embedded image, so use the File's url property instead of its nativePath.
image.source = File.documentsDirectory.resolvePath('image.jpg').url;

I am new to flex and I am trying to open modules in a new window modal.
I have managed to load and add a module in a container ( vbox ) but what I really need is to open them in separate windows.
All posts that I could find are samples on how to load modules but nothing on how to show them.
I found a post here
Modules and Panels issue
and it looks by the screenshot exactly what I am looking for.
Thanks for your help.
I found a way of doing this.
Thanks for all the pointers
here is how I did it for all of you to see and maybe use. If you have suggestions to make it better, do not hesitate to comment.

I'm making simple editor. And I want that, let write replacing colorless text to color text from RichEditableText when I will write any text.
For example:
PHP --> <s:span color="#FF0000">PHP<s:span>

editorum.text = editorum.text.replace('PHP','<s:span color="#FF0000">php<s:span>');
Editorum is: <s:RichEditableText id="editorum" ></s:RichEditableText>

A other problem; How do I send the pointer at the end? When I press any key, pointer going to deal. Try: http://samed.us/samples/ops3.swf
Thanks for your help...
Instead of this line:
editorum.text = editorum.text.replace('melon','<s:span color="#FF0000">melon<s:span>');
Try something like this:
var text : String = editorum.text.replace('melon','<s:span color="#FF0000">melon<s:span>')
editorum.textFlow = TextConverter.importToFlow(text, TextConverter.TEXT_FIELD_HTML_FORMAT);
Basically, you need to convert the HTML into something that the TLF Framework will understand. Read some docs on textFlow and the TextConverter
I'm trying to preview a PDF file into a Flex (AIR) application : I am using the mx.controls.HTML component and it works perfectly when I build my project into flex builder. But when exporting to a validated version : I can preview a web page but not a PDF file. Do you have any idea ?
Thanks,
Nicolas

I need to dynamically create a LinkButton with an icon. The names of files (icons) have the format images/icon_0.png, images/icon_1.png, ... images/icon_1000.png. But I don't know the specific image for this button. I only know the index of the icon.
I tried this, with no success:
var path:String = "#Embed(source='images/icon_" + imageindex + ".png')";
myButton.setStyle("icon", path);
I get a runtime error:
Type Coercion failed:
*cannot convert "#Embed(source='images/icons/icon_427.png')" to Class*
Sorry that will not work.
Since imageindex is a compile-time variable, then embedding tag will trigger an error message.
Why not to override the button and add extra property like 'iconPath' that will expect a string path instead of a Class object. This way you can manually set (inside extended Button) the icon.source = iconPath without having to use embed.
pls try this.

if you have a sprite/movieclip, that uses 9slice-scaling and you scale this thing directly, it works nicely. If this things is a child of another sprite/movieclip/whatever and you scale that one, the 9slice-scaling of your child does not work anymore.
A workaround for this is normally to write functions, that take size-change requests and then resize the children that use9slice-scaling directly, instead of resizing themselves.
