我有这个:
import javax.swing.*;
import java.awt.Canvas;
import java.awt.image.BufferedImage;
public class test extends Canvas{
public static JFrame frame;
public static int WIDTH = 800;
public static int HEIGHT = 600;
public static BufferedImage img;
public static int[] pixels;
public static boolean running=true;
public static void main(String[] a){
img = new BufferedImage(WIDTH, HEIGHT,BufferedImage.TYPE_INT_RGB);
frame = new JFrame("WINDOWw");
frame.add(new JLabel(new ImageIcon(img)));
frame.pack();
frame.setVisible(true);
frame.setSize(WIDTH, HEIGHT);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
如何阻止黑色图像在框架上自动居中?
最佳答案
它似乎是唯一的组件,它填充了框架。如果它是唯一的组件,请使用文本对齐或 FlowLayout
。
import javax.swing.*;
import java.awt.FlowLayout;
import java.awt.image.BufferedImage;
public class TestLabelPlacement {
public static JFrame frame;
public static int WIDTH = 200;
public static int HEIGHT = 150;
public static BufferedImage img;
public static void main(String[] a){
img = new BufferedImage(WIDTH, HEIGHT,BufferedImage.TYPE_INT_RGB);
frame = new JFrame("Window");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new FlowLayout(FlowLayout.LEADING));
frame.add(new JLabel(new ImageIcon(img)));
frame.pack();
frame.setVisible(true);
// WRONG! That is the size of the image, not the frame!
//frame.setSize(WIDTH, HEIGHT);
}
}
关于java - JLabel图像图标: stop auto centering in the frame,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/11260809/
