I'm writing a wrapper around the core Flex HTML engine to add tabbed browsing. Everything works fine for links with targets of _self or _top. I had to scan all the links on each page and add click handling when the target was new or _self (to re-route the calls into my own tabbing engine). However, I'm running into trouble with Flash-based ads.
Because Flash-based ads use getURL or navigateToURL, I don't see any event handling structure I can use. I've been trying to figure out how I might go about overriding flash.net.navigateToURL, but to no avail. Does navigateToURL dispatch an event I'm missing? Is it possible to override the method to redirect the calls to my own tabbing engine?
