How to get the active Paragraph?

  • February 2, 2010

I have following TLF XML:

private var text:XML =

<flow:TextFlow fontSize="20" paddingRight="50" paddingBottom="50" paddingTop="50" paddingLeft="50" whiteSpaceCollapse="preserve" xmlns:flow="http://ns.adobe.com/textLayout/2008">
        <flow:p>
                 <flow:span>Hallo liebers Programmili... du tust schon langsam meinem koepchen weh</flow:span>
        </flow:p>

</flow:TextFlow>;

I try to get the Paragraph for a selection inside the text using following Methodes:

var index:int = tf.interactionManager.anchorPosition; // i get 29 here
var child:FlowElement = tf.getChildAtIndex(index); // undefined - it should be the flowElement containing the text... <flow:span></flow:span>
var para:ParagraphElement = test.getParagraph();//undefined - it should be the paragraph

I really started to enjoy the new framework... but now i am getting really mad

Can anybody imagine what i am doing wrong? The undefined itself makes me suspicious... shouldn't it be null?

Help would be much appriciated!

Correct answer rdermer

You are confusing index and position.

What you want is:

var position:int = tf.interactionManager.anchorPosition;     // this is a position not an index

var leaf:FlowLeafElement = tf.findLeaf(position);     // maps a position to a leaf

var para:ParagraphElement = leaf.getParagraph();     // find the leaf element's owning paragraph

Also consider whether you want the anchorPosition or the activePosition.  In a point selection they are the same.  In a block selection the anchor is where the block began and the active is the end being modified by the UI (mouse dragging and keys).

Hope that helps,
