Re: [flexcoders] invalidateDisplayList()

[Jeremy Lu]

In your updateDisplayList() function, you can add an "if" clause to detect which part should be redrawn.Something like :if( dotChanged ){    //do redraw}Jeremy.

Hi,
 
Does calling 
invalidateDisplayList() on a control mean that *everything* (including parents) 
gets re-drawn, or just the children?
 
I have something 
similar to Ely Greenfield's RangeSelector class (
http://demo.quietlyscheming.com/overlayDemo/), 
but the mousemove event seems to cause my PlotSeries to re-draw too. This means, 
when I have 1000 points on my chart, the draggable box is very 
sluggish.
 
I thought a 
control's updateDisplayList() would only be called if something on that actual 
control changed?
 
Thanks,
 
Danny
