Java在JFrame上圆角？ [英] Java rounded corners on JFrame?

问题描述

我的应用程序有一个登录JFrame，我想让框架的角落几个像素点。

I have a login JFrame for my application and i would like to make the corners of the frame rounded by a few pixles.

我想这样做而不使用JFrame上的透明度并且必须在JPanel中使用背景图像 - 这可能吗？

Id like to do this without using transparency on the JFrame and having to use a background image inside a JPanel - is this possible?

推荐答案

这可能是未修饰的框架，请考虑以下示例：

It's possible with undecorated frame, consider the following example:

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);

此代码适用于Java 7.对于Java 6（自更新10起），您可以执行相同的操作 AWTUtilities.setWindowShape ：

This code works on Java 7. For Java 6 (since update 10) you can do the same with 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);
