Making a panel and its contents transparent

[Kaish]

Hi guys,

I'm coding an app that draws a little circle every time a user clicks
the mouse. This is fine and working. However, I want to be able to
toggle all the circles between visible and invisible.

The best way I can think of is to create one big panel and put all my
other panels containing their components inside it, then make a
checkbox that sets that big panel's opacity to false. I do this, but
the panel remains exactly the same.

I thought it might have been a repaint() problem, so I tried making
the panel not opaque at initialization, but all the components inside
still remain visible.

Am I missing something obvious?

Thanks,
Kaish

The Opacity of the panel does not apply
to things inside it, only things *behind*
it.
