法律研究如何在 Java 中创建嵌套 JSplitPane？
首先，让我们创建三个组件 -
JComponent one = new JLabel("Label One");
one.setBorder(BorderFactory.createLineBorder(Color.yellow));
JComponent two = new JLabel("Label Two");
two.setBorder(BorderFactory.createLineBorder(Color.orange));
JComponent three = new JLabel("Label Three");
three.setBorder(BorderFactory.createLineBorder(Color.blue));现在，我们将分割一个和两个组件。
JSplitPane split1 = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, one, two); split1.setDividerLocation(0.5); split1.setDividerSize(2);
之后，上述分割的面板将与第三个组件进行分割，使其嵌套 -
JSplitPane split2 = new JSplitPane(JSplitPane.VERTICAL_SPLIT,split1, three ); split2.setDividerLocation(0.9); split2.setDividerSize(2);
以下是创建嵌套 JSplitPane 的示例 -
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));
JSplitPane split1 = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, one, two);
split1.setDividerLocation(0.5);
split1.setDividerSize(2);
JSplitPane split2 = new JSplitPane(JSplitPane.VERTICAL_SPLIT,split1, three );
split2.setDividerLocation(0.9);
split2.setDividerSize(2);
frame.add(split2,BorderLayout.CENTER);
frame.setSize(550, 250);
frame.setVisible(true);
}
}输出
