[英]how to make components visible in a transparent JFrame
I have some JButtons in a JFrame (its layout is null). 我在JFrame中有一些JButton(其布局为null)。 The background Color of the buttons are set Black.
按钮的背景色设置为黑色。 I have made the JFrame Transparent by using this code.
我已经通过使用此代码使JFrame透明。
AWTUtilities.setWindowOpacity(this, 0);
But the problem is it also makes all the buttons transparent as well. 但是问题在于它也使所有按钮也透明。 I don't want that.
我不要 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).
我想看到按钮保持黑色,但JFrame的其他部分变成透明的(以便可以看到桌面背景)。 Please someone help me.
请有人帮我。 Thanks in advance.
提前致谢。
使用通话button.setOpaque(true)
怎么样?
Yeh, the problem was opacity set to zero. 是的,问题是不透明度设置为零。 Any non-zero value with all button.setOpaque(true), will display buttons clearly.
所有button.setOpaque(true)的任何非零值都将清楚显示按钮。 For me, AWTUtilities.setWindowOpacity(frame, 0.7f) works too.
对我来说,AWTUtilities.setWindowOpacity(frame,0.7f)也可以工作。
