Java rounded corners on JFrame?
提问by Alosyius
I have a login JFrame for my application and i would like to make the corners of the frame rounded by a few pixles.
我有一个用于我的应用程序的登录 JFrame，我想让框架的角由几个像素四舍五入。
Id like to do this without using transparency on the JFrame and having to use a background image inside a JPanel - is this possible?
我想这样做而不在 JFrame 上使用透明度并且必须在 JPanel 内使用背景图像 - 这可能吗？

It's possible with undecorated frame, consider the following example:
使用未装饰的框架是可能的，请考虑以下示例：
JFrame frame = new JFrame();
frame.setUndecorated(true);
frame.setShape(new RoundRectangle2D.Double(10, 10, 100, 100, 50, 50));
frame.setSize(300, 200);
frame.setVisible(true);
This code works on Java 7. For Java 6 (since update 10) you can do the same with AWTUtilities.setWindowShape:
此代码适用于 Java 7。对于 Java 6（自更新 10 起），您可以使用以下命令执行相同操作AWTUtilities.setWindowShape：
JFrame frame = new JFrame();
frame.setUndecorated(true);
AWTUtilities.setWindowShape(frame, new RoundRectangle2D.Double(10, 10, 100, 100, 50, 50));
frame.setSize(300, 200);
frame.setVisible(true);

Try this. It works :)
尝试这个。有用 ：）
yourframe.setUndecorated(true);
yourframe.setBackground(new Color(0, 0, 0, 180));
yourframe.addComponentListener(new ComponentAdapter() {
@Override
public void componentResized(ComponentEvent e) {
setShape(new RoundRectangle2D.Double(0, 0, getWidth(), getHeight(), 80, 80));
}
});
