如何在 Java 中创建左右分割窗格?
java 8object oriented programmingprogramming
要创建左右分割窗格，让我们创建两个组件并将它们分割成 −
JComponent one = new JLabel("Left Split");
one.setBorder(BorderFactory.createLineBorder(Color.MAGENTA));
JComponent two = new JLabel("Right Split");
two.setBorder(BorderFactory.createLineBorder(Color.ORANGE));
现在，我们将分割它们。两个组件将使用 HORIZONTAL_PANE 常量从左到右分割 −
JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, one, two);
以下是在 Java 中创建左右分割窗格的示例 −
示例
package my;
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("SplitPane Demo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JComponent one = new JLabel("Left Split");
one.setBorder(BorderFactory.createLineBorder(Color.MAGENTA));
JComponent two = new JLabel("Right Split");
two.setBorder(BorderFactory.createLineBorder(Color.ORANGE));
JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, one, two);
frame.add(splitPane);
frame.setSize(550, 250);
frame.setVisible(true);
}
}
这将产生以下输出 −
