如何在 Java 中创建左右拆分窗格?
要创建左右拆分窗格,我们将创建两个组件并拆分它们 −
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,我们将拆分它们。这两个组件将使用 HORIZONTAL_PANE 常量拆分,一个在另一个的左边 −
JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, one, two);
以下是一个在 Java 中创建左右拆分窗格的示例 −
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);
}
}这会产生以下输出 −
