Here is a simple example, of how you can use the new Flex 4(Gumbo) API to skin components and have them do Transitions. The Rectangular Component on is a basic UIComponent and when you hover it rotates and the color changes, the Button on the right side expand when you hover over it too and returns to its normal state when the mouse is off of it. I have more complex examples lined up and will post them as the days go by. The next example will be on Skinning buttons and using Tweener, AnimateColor , excludeFrom property and other things. Need Flash Player 10 to view it
