法律研究如何在 Java 中创建 JSplitPane 来划分组件？
首先，设置我们要划分的两个组件 −
JComponent one = new JLabel("Label One");
one.setBorder(BorderFactory.createLineBorder(Color.yellow));
JComponent two = new JLabel("Label Two");
two.setBorder(BorderFactory.createLineBorder(Color.orange));现在，使用 SplitPane 分割它 −
示例
package my;
import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.BorderFactory;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JSplitPane;
public class SwingDemo {
public static void main(String[] a) {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JComponent one = new JLabel("Label One");
one.setBorder(BorderFactory.createLineBorder(Color.yellow));
JComponent two = new JLabel("Label Two");
two.setBorder(BorderFactory.createLineBorder(Color.orange));
JComponent three = new JLabel("Label Three");
three.setBorder(BorderFactory.createLineBorder(Color.blue));
JComponent four = new JLabel("Label Four");
four.setBorder(BorderFactory.createLineBorder(Color.green));
JSplitPane split1 = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);
split1.setLeftComponent(one);
split1.setRightComponent(two);
JSplitPane split2 = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);
split2.setLeftComponent(three);
split2.setRightComponent(four);
frame.add(split1, BorderLayout.NORTH);
frame.add(split2, BorderLayout.SOUTH);
frame.setSize(550, 250);
frame.setVisible(true);
}
}输出
