Light Box Effect (2 Windows, 1 Smaller And Active Above InactiveGrayed-Out Window)
 
Does anybody have a project that will give me a Light Box effect to a project.

A Light Box Effect produces two windows. One window will be active, but the one below it will be inactive and grayed out.

Here's an image of what I want to achieve.

I'm not interested in licensed code.

Thank you,

There's a class JLayer which provides the basics. You'll have to
provide a fair amount of code though; I'm not aware of any class that
provides a lightbox feature.

There's also a book call Swing Hacks which has some interesting ideas,
including an animated window similar to what you are asking for. Still
not exactly a lightbox however.

Is there another way besides using JLayer. Is JLayer the best way.

Thank you,

I think it might be the only way, short of doing it yourself like that
Swing Hacks books shows you. "Best" is a hard thing to determine
without careful analysis. But JLayer is certainly the way I would
start, even if I decided later I had to change. Can't go too badly
wrong re-using code someone else already wrote.

Here's the HACK #45 code from the book. It has two buttons. If you press one of th buttons everything on the screen will move away and the screen will become blank.

Question: How on Earth do I convert this into a light box effect.

Here is a link to other fun JLayer examples:
