How do you add a border to text elements using TLF? This seems like something that should be extremely simple yet I’ve been hunting for days. I’m currently doing something like this:

protected var _textFlow:TextFlow; protected var _editManager:EditManager;


var _textLayoutFormat:TextLayoutFormat = new TextLayoutFormat();

// I add a whole bunch of formatting such as:

_textLayoutFormat.color = 0xff0000;

_textLayoutFormat.fontFamily = "Arial, Helvetica, _sans";

//but of course there's no border-like settings here.
_textFlow = new TextFlow();

_textFlow.hostFormat = _textLayoutFormat;

_textFlow.flowComposer = new StandardFlowComposer();

_textFlow.flowComposer.addController(new ContainerController(this));

_editManager = new EditManager();

_textFlow.interactionManager = _editManager;

_textFlow.flowComposer.updateAllControllers();
// ... and later to "activate" it...

_textFlow.interactionManager.selectRange(0,0); _editManager.setFocus();

I was playing around with a TextContainerManager before, too… but I guess I just didn’t understand it enough. I see on help.adobe.com it says about the drawBackgroundAndSetScrollRect method, “Override this method to draw a background or a border. Overriding this method can be tricky as the scrollRect must be set as specified.”

I guess I’ll look into that, although… I’m not sure where to begin yet. (Any recommendations?)

I was using Flex Builder 3. It’s good to know that Flash Builder will help me avoid forgetting that setting though.

Rob,

Out of curiosity, are you using Flex Builder 3, or Flash Builder 4 beta? If you are using FB4, it should correct the Player version automatically based on the current SDK version (unless you disabled that).

Ok… slightly embarrassed now. I forgot to change the required Flash player version to 10 in the projects properties.

I must be missing something because this doesn’t appear to compile even when using the nightly (8654 build) SDK. I get several “Type was not found or was not a compile-time constant” errors pointing at TextBlock and TextLine as the missing classes.
