Absolutely. If another javascript manages to do something in a
browser, then you can do it in GWT. A good starting place would be
to look at is the following class:
com.google.gwt.animation.client.Animation
It's an abstract class that you extend. There's a mechanism that
repeatedly calls this method that you implement:
onUpdate(double progress)
The "progress" argument will be between 0.0 and 1.0, which tells you
how far along you are in the animation step. (Think of it as a
percentage.) Using that number, you can decide, for example, exactly
how "zoomed", or "faded", or "moved" your widget or element is. When
the animation starts, the value will be 0.0. When it's done, it will
be 1.0. In between, the Animation class provides a nice "easing
function" that gives something a bit more natural than straight linear
interpolation would. The nice thing about it is that you don't have
to think about the easing function. The abstract superclass will just
call onUpdate() and let you know how far along you are.
