Transparent Window

问题

I have a fullscreen JFrame. I added a map to JPanel then added it to JFrame. Now I want to add a transparent window to JFrame. I want to see all map and I want to move transparent window.

I did it with internal frame but I couldn't it's title tranparent.

Could you help me about this?

One possible way is to add a JPanel to the glasspane.

Does com.sun.awt.AWTUtilities.setWi­ndowOpacity(this, 0.3f); work? (although it's not an officially supported API, natch). Regardless, there's an article on this here.
