在 Java 中使 JSlider 垂直并从上至下移动
java 8object oriented programmingprogramming更新于 2025/8/29 5:00:17
要将 JSlider 设置为垂直，请在创建滑块时使用 VERTICAL 常量 −
JSlider slider = new JSlider(JSlider.VERTICAL, 0, 100, 60);
现在，对于反转滑块，即从上至下移动 −
slider.setInverted(true);
以下是将滑块设置为垂直并从上至下移动的示例 −
示例
package my;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JSlider;
import javax.swing.WindowConstants;
public class SwingDemo {
public static void main(String[] args) {
JFrame frame = new JFrame("Frame with Slider");
JSlider slider = new JSlider(JSlider.VERTICAL, 0, 100, 60);
slider.setInverted(true);
slider.setMinorTickSpacing(5);
slider.setMajorTickSpacing(20);
slider.setPaintTicks(true);
slider.setPaintLabels(true);
JPanel panel = new JPanel();
panel.add(slider);
frame.add(panel);
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.setSize(600, 300);
frame.setVisible(true);
}
}
输出
