How to make selected text in text area bold,italic etc and then add it on rich text?

I made selected text in text area bold,italic etc but i am not able to maintain bold ,italic properties when adding text on rich text.


Ok, look. Let's analyze our problem step by step:

Problem: we have text and we need to change selected text of initial text to bold;


1) Take a selection text to separate string

2) Change style of separate string to bold(or other style)

3) Collect initial not-bold strings with bolded sting and show result :)

I think there are several ways to resolve this, but i propose the following:

<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="" 
    xmlns:s="library://" title="Test">
    <s:RichEditableText id="ret" text="Test Text String for selection" />
    <s:Button id="btnBold" label="Set Bold for Selection" click="btnBold_clickHandler(event)"/>
    <!-- Place non-visual elements (e.g., services, value objects) here -->

        import flashx.textLayout.conversion.TextConverter;

        protected function btnBold_clickHandler(event:MouseEvent):void

        private function setBoldForSelectionTex():void
            var startSelectionPos:int   = 0;
            var endSelectionPos:int     = 0;

            if(ret.selectionActivePosition > ret.selectionAnchorPosition)
                endSelectionPos     = ret.selectionActivePosition;
                startSelectionPos   = ret.selectionAnchorPosition;
                endSelectionPos     = ret.selectionAnchorPosition;
                startSelectionPos   = ret.selectionActivePosition;

            var initialString:String    = ret.text;
            var startString:String      = ret.text.toString().substr(0, startSelectionPos);
            var middleString:String     = ret.text.toString().substr(startSelectionPos, endSelectionPos - startSelectionPos);
            var endString:String        = ret.text.toString().substr(endSelectionPos, initialString.length - endSelectionPos);
            var completeString:String   = startString +"<b>" + middleString + "</b>" + endString;

            ret.textFlow = TextConverter.importToFlow(completeString, TextConverter.TEXT_FIELD_HTML_FORMAT);

I hope this help you.
