Question

I’ve a TextArea that I want to use for code input (xml). How do I allow for entering tabs (pressing tab moves focus to nect control)?

Answer 1

The only way I’ve found to do this is the extend TextArea and catch it’s keyFocusChange event, then stop the event and insert the tab. Here is an example:

<?xml version='1.0' encoding='utf-8'?> <mx:Application xmlns:mx='http://www.adobe.com/2006/mxml' xmlns='*'>    <mx:Component className='MyTextArea'>     <mx:TextArea width='300' height='300'>       <mx:keyFocusChange>         event.preventDefault();         this.textField.replaceSelectedText('\t');       </mx:keyFocusChange>     </mx:TextArea>   </mx:Component>    <MyTextArea width='300' height='300'/>    <mx:TextArea width='300' height='300'/>  </mx:Application> 

You can also break the MyTextArea out into a separate class file. But I put it all in one file because it’s easier to test.
