I have a canvas container with="100%". When the user clicks a button, the container is set to percentWidth=20, and I need to immediately know the new width so that I can properly re-size elements in the container to match the new width.
>From what I can tell, the LayoutManager doesn't get to measuring the new width >of the container right away. If the user clicks the button again, the >LayoutManager has done it's thing and has set the width value of the canvas. So the question is, how do I get the new width of the canvas as soon as I set percentWidth=20?
