Title: cut copy paste code
I need to do cut ,copy and paste in a textarea .what code i should write?
HELP PLEASE
1
try this
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Panel title="TextArea Control Example" height="75%" width="75%"
paddingTop="10" paddingBottom="10" paddingLeft="10" paddingRight="10">
<mx:TextArea width="400" height="100">
<mx:text>
This is a multiline, editable TextArea control. If you need
a non-editable multiline control, use the Text control.
</mx:text>
</mx:TextArea>
</mx:Panel>
</mx:Application>
