how to make components visible in a transparent JFrame

Question

I have some JButtons in a JFrame (its layout is null). The background Color of the buttons are set Black. I have made the JFrame Transparent by using this code.

AWTUtilities.setWindowOpacity(this, 0);

But the problem is it also makes all the buttons transparent as well. I don't want that. I want to see the buttons remaining black but the other portions of the JFrame becoming transparent (so that I can see the desktop background). Please someone help me. Thanks in advance.

Answer 1

使用通话button.setOpaque(true)怎么样？

Answer 2

Yeh, the problem was opacity set to zero. Any non-zero value with all button.setOpaque(true), will display buttons clearly. For me, AWTUtilities.setWindowOpacity(frame, 0.7f) works too.
