Suppress mouse events on child components - Flex3

A college of mine showed me that in order to suppress mouse events on children components is by the obscure property of mouseChildren = false;

I use it when i want to catch a mouse event on a container, regardless of the component within that container that was exactly under the mouse.

There is no way under the heavens to guess this is the functionality of a property with such a name.

Thanks Liran.
