Flex Component Lifecycle: validateNow, validateDisplayList, invalidateDisplalList, commitProperties, etc.

Question

I am expanding VBox to create a calendar component. Which method should I override to add code for drawing? What is the difference between all of these methods? Is there something I have to put in each, or is there a specific method that I can just override, add my drawing code and make it work?

Thanks!
