RE: [flexcoders] Access mouse selection

Hi,

You can use the Selection Object for the same. Tracy already posted the
link of docs.

Just wrote a quick and dirty example, look at it and read the comments
in the code to know what is happening.

##SelectionObjectExample.mxml##

<?xml version="1.0" encoding="iso-8859-1"?>
<mx:Application width="800" height="600"
xmlns:mx="http://www.macromedia.com/2003/mxml"; >

    <mx:Script>
        <![CDATA[
        
        var lastFocussedObject:Object = null;
        var beginIndex:Number;
        var endIndex:Number;
        
        function getSelectedText():String
        {
            //get the reference of currently focussed object.
            var obj:Object = ta.getFocus();
                      
            //store the reference of currently focussed object
             lastFocussedObject = obj;
            
            //check if it is a selectable textfield
            if(obj instanceof TextField && obj.selectable == true)
            {
                //get the selection based on beginIndex and endIndex
                beginIndex = Selection.getBeginIndex();
                endIndex = Selection.getEndIndex();
                var selectedText:String =
obj.text.substring(beginIndex,endIndex);
              
                alert("Selected Text: " + selectedText);
               
               return selectedText
            }
            else
            {
                //return null when selected object is not a TextField
                return null;
            }
            
        }
        
        //this function restores the focus to the last selected object.
        function restoreFocus()
        {
            //set the focus back to the last focussed object
            Selection.setFocus(lastFocussedObject);
            
            //if it was TextField
            if(lastFocussedObject instanceof TextField) 
            {
                //set the selection also
                Selection.setSelection(beginIndex, endIndex)
                beginIndex = endIndex = 0;
            }
            
        }

Hope that helps

Subject: [flexcoders] Access mouse selection

Hello list,

I searched for a reasonable time but got no working result.

I'd like to know how do I access with ActionScript the selected text, 
the user can select with the mouse in a editable textarea. Just the 
selection, before copied or cut...

Background I want to modify the selection and return the modifications 
just in time. I'm playing with an online thesaurus based on a webservice

and I want to pass the selected text in a webservice call.

Thanks in advance

Reto
