Hello,

I saw this question a few times here and there but it never had a satisfying answer… It may be that there really is no elegant way to solve this (Polling for change in ENTER\_FRAME is really bad!) but I’ve got to ask one last time.

I’m a Flex developer but it doesn’t really matter in this case.

I would like to know when an object’s global x/y was modified (or its transform’s concatenated matrix’s tx/ty, same thing), maybe because an indirect parent somewhere moved, etc.

In particular, I have the object’s gran gran gran parent which gets its scrollrect changed.

Any brilliant idea in 2011 ? 🙂
