I have a custom component (X), a child in canvas1. I'm trying
to use a move
effect to move it from canvas1 to canvas2.
I also want X to become canvas2's child at the end.
When I apply a move effect on X, it moves only within
canvas1, and an ugly scroll bar appears at the bottom of the
canvas, because, I guess, X remains a child of canvas1.
should I use removeChild() and addChild() manually ? or is
there a better way ?
