Re: [flexcoders] best general purpose way to keep textarea scrolled to bottom

Very nice!  Works fine for me in release.On 7/13/06, Darron J. Schall <[EMAIL PROTECTED]> wrote:













  


    
            



I've done this in the past through code like the following:

textArea.addEventListener( FlexEvent.VALUE_COMMIT, autoScrollToBottom );

private function autoScrollToBottom( event:FlexEvent ):void
    {
        // Auto-scroll to the bottom anytime the text changes
        event.target.validateNow();
        event.target.verticalScrollPosition =
event.target.maxVerticalScrollPosition;
    }

Essentially, with the above code you never have to explicitly tell the
text area to scroll to the bottom - it will automatically do that
anything the text property changes programmatically.  So, anytime you
assign the text to be something else, your scrollbar will automatically
adjust for you.

This is code I've used in the past with beta 3, and I haven't tried it
with the released version, so it's not guaranteed to work.  :-)

  I wish TextArea had a property that would set it to scroll to the
bottom on adding text.  In the absence of such, I'm struggling to make
it do that.  I have a log function that looks like this:
  
    private function
log(s:Object):void {
      debug.text +=
"\n" + s.toString();
     
debug.verticalScrollPosition = debug.maxVerticalScrollPosition;
    }
  
Unfortunately, it seems that the max position isn't updated yet at this
point.  I've tried hooking into change/dataChange and other events
without luck.  It's always scrolled ALMOST to the bottom.
  
  
What's the best way to solve this?
