如何将图像添加到 JFrame 标题栏? [英] How to add an image to a JFrame title bar?

问题描述

我想在 javax.swing.JFrame 标题栏添加一个图像(小图标).

I want to add an image (small icon) to the javax.swing.JFrame title bar.

我该怎么做?

推荐答案

由于 JPanel 没有标题栏，我假设您指的是 JFrame.话虽如此，请使用 setIconImage(...).

Since JPanel doesn't have a title bar, I'm assuming that you're referring to JFrame. That being said, use setIconImage(...).

这里是一个使用setIconImages()的例子.

Here is an example of using setIconImages().

import java.awt.Image;
import javax.swing.*;
import javax.imageio.ImageIO;

import java.net.URL;
import java.util.*;

class FrameIcons {

    public static void main(String[] args) throws Exception {
        URL url16 = new URL("http://i.stack.imgur.com/m0KKu.png");
        URL url32 = new URL("http://i.stack.imgur.com/LVVMb.png");

        final List<Image> icons = new ArrayList<Image>();
        icons.add(ImageIO.read(url16));
        icons.add(ImageIO.read(url32));

        SwingUtilities.invokeLater( new Runnable() {
            public void run() {
                JFrame f = new JFrame("Frame Icons");
                f.setIconImages(icons);
                f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                f.setLocationByPlatform(true);
                f.setSize(200,100);
                f.setVisible(true);
            }
        });
    }
}

使用 16x16 图标的框架
