getCharIndexAtPoint() equivalent in Spark RichEditableText

Question

I want to find a way to get the character index in a Spark based RichEditableText based on mouse x, y position.

The mx.controls.TextArea has a protected getCharIndexAtPoint() method but I can't find an equivalent of this in the Spark RichEditableText which is disappointing.

Any ideas or recommendations?

There is a tlf_internal function you can use to do this. If you can get the textFlow (I think this is the RichEditableText.content), you can call:

import flashx.textLayout.edit.SelectionManager;

import flashx.textLayout.tlf_internal;

use namespace tlf_internal;

SelectionManager.computeSelectionIndex(textFlow:TextFlow, target:Object, currentTarget:Object, localX:Number,localY:Number)
