Java 删除frame.add（组件）时，组件必须是有效的对等方
我这里有一段代码，用于创建像素数组并将其绘制到图像中：Java 删除frame.add（组件）时，组件必须是有效的对等方,java,swing,awt,bufferedimage,Java,Swing,Awt,Bufferedimage,我这里有一段代码，用于创建像素数组并将其绘制到图像中： import javax.swing.JFrame; import java.awt.Canvas; import java.awt.Graphics; import java.awt.image.BufferStrategy; import java.awt.image.BufferedImage; import java.awt.image.DataBufferInt; public class test extends Canvas
import javax.swing.JFrame;
import java.awt.Canvas;
import java.awt.Graphics;
import java.awt.image.BufferStrategy;
import java.awt.image.BufferedImage;
import java.awt.image.DataBufferInt;
public class test extends Canvas implements Runnable {
private static final long serialVersionUID = 1L;
public static int WIDTH = 800;
public static int HEIGHT = 600;
public boolean running = true;
public int[] pixels;
public BufferedImage img;
public static JFrame frame;
private Thread thread;
public static void main(String[] arg) {
test wind = new test();
frame = new JFrame("WINDOW");
frame.add(wind);
frame.setVisible(true);
frame.setSize(WIDTH, HEIGHT);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
wind.init();
}
public void init() {
thread = new Thread(this);
thread.start();
img = new BufferedImage(WIDTH, HEIGHT, BufferedImage.TYPE_INT_RGB);
pixels = ((DataBufferInt) img.getRaster().getDataBuffer()).getData();
}
public void run() {
while (running) {
render();
try {
thread.sleep(55);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
public void render() {
BufferStrategy bs = this.getBufferStrategy();
if (bs == null) {
createBufferStrategy(4);
return;
}
drawRect(0, 0, 150, 150);
Graphics g = bs.getDrawGraphics();
g.drawImage(img, 0, 0, WIDTH, HEIGHT, null);
g.dispose();
bs.show();
}
private void drawRect(int x, int y, int w, int h) {
for (int i = x; i < w; i++) {
for (int j = x; j < h; j++) {
pixels[i + j * WIDTH] = 346346;
}
}
}
}
我为什么要删除它？因为我想使用一个类对象（来自另一个文件）创建一个框架，并使用代码
Window myWindow=new Window（）Frame画布Frame缓冲区策略JComponent这是一个摇摆的时代，为什么你要使用
CanvasJPanelDoubleBufferingJPanelCanvasThread.sleep（…）frame.add(wind);
