Ugly way #1: Try adding a listener to SystemManager for the FlexEvent.SHOW and FlexEvent.HIDE event using the capture phase. Then when that comes in loop over all the children of the component that is being shown and do whatever it is you need to do when you find a certain component is being shown or hidden
Ugly way #2: monkey patch UIComponent. Change the getter for visible. If the UIComponent has normal visibility set to true, then check if it has a parent, if so return the parent's visibility (and since you're monkey patching UIComponent that would trickle all the way up the display list) What is it exactly that you need to do if somewhere up in the display list a parent has visible set to false?
