For a hovering-mechanism, i need to know if the mouse is currently over a component, even if this mouse is currently over a containing&nbsp;component (with also has interaction, so hitTest is no option).

Does anybody has an idea how to quickly solve that? (without modification of the child components)

You can do this with a MouseListener.. They can be set to listen to all events in all subcomponents of the one you attach it to.

No, just pass true as the second parameter to addMouseListener, that will automatically recieve events from all nested components. Then just check the mouse position relative to the parent to see if the mouse is still inside or not.
