要添加具有相对 X 和 Y 坐标的组件，您需要同时设置 gridx 和 gridy 组件 −
GridBagConstraints Constraints = new GridBagConstraints(); Constraints.gridy = GridBagConstraints.RELATIVE; Constraints.gridx = GridBagConstraints.RELATIVE;
以下是添加具有相对 X 和 Y 坐标的组件的示例 −
示例
package my;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class SwingDemo {
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
panel.setLayout(new GridBagLayout());
GridBagConstraints constraints = new GridBagConstraints();
constraints.gridx = 1;
constraints.gridy = GridBagConstraints.RELATIVE;
panel.add(new JButton("1st row 1st column"), constraints);
panel.add(new JButton("2nd row"), constraints);
panel.add(new JButton("3rd row"), constraints);
constraints.gridx = GridBagConstraints.RELATIVE;
panel.add(new JButton("1st row 2nd column"), constraints);
panel.add(new JButton("1st row 3rd column"), constraints);
frame.add(panel);
frame.setSize(550, 300);
frame.setVisible(true);
}
}
输出
