Try Deepa's talk from MAX, it was really good on creating components in Flex 3.

(i.e. a class that extends UIComponent) I've actually done it before, but had some bugs and headaches because I didn't fully understand all the intricacies of method overriding you have to/should do - things like measure(), clone(), updateDisplayList (), etc. - so that it looks/works right and the UIComponent stays within its container (for example, you create a UIComponent that draws a large circle, but you want the circle to remain within the bounds of a scrollpane component it is a child of). I've googled all over the place, including adobe devnet and the Flexcoders archives and have come up short. Seems to be bits and pieces - I'm looking for some kind of explanation or simple example of writing a visual component I understand the AS3 drawing API and databinding, I just want info on the rest of best practices for extending UIComponent. Seems like I had seen a tutorial on this before on devnet, but I can't locate it now (the search on that thing is terrible!) - also others have made some good posts on that here as well, but can't find those either. Thanks!
