Event or way to check when a component has visibility change

[Brown, Berlin [GCG-PFS]]

With the 1.4 release of wicket, is there a way to determine when a
component has changed visibility.  Mainly from false to true visibility.
 
I can use onBeforeRender or onConfigure to determine when the component
is being rendered.
 
onAfterRender will get called after it is rendered but the component is
still visible.

onBeforeRender() is not called for invisible components

Is there another method to determine when the visibility of a component has changed.

E.g.

If a window is shown (through ajax possibly): Some listener

Onevent() { this is visible }

...

Onevent2() { this is now being changed to not visible }
