How to develop transparent interface?

Question

This is not completely a programming question. Today when I load LiLi USB creator software I saw the interfaces are transparent. Is that because they are Photoshopped or is transparency a technique of IDE? I'm using both NetbBeans and Eclipse. To be clear, I'm adding a photo too.

Answer 1

For transparency of the entire GUI, including controls (which doesn't seem to be the case in your screenshot), .NET includes the Form.Opacity property.

Additionally, it may be possible to use LayeredWindows to change only the opacity of the top-level component to produce the desired effect.

For Java specifically, there's an official Java tutorial for that, although it seems to set the opacity of the entire window, including all child components.
