Creating animation when screen diomension can change- Flex 4

Question

I am trying to create animation which is based on user input on speed and distance... also it needs to work consistently on different screens and resolution

what functions do i use to get the pixel size of the container where the animation is playing- to make the calculations?

Answer 1

listen for keyboard events, like here http://blog.flexexamples.com/2008/08/04/closing-a-pop-up-window-using-the-keyboard-in-flex/

get any UIComponent width and height by using:

blah=yourComponent.width
