要创建垂直进度条，请使用以下属性 −
JProgressBar.VERTICAL
像这样设置 −
JProgressBar progressBar = new JProgressBar(JProgressBar.VERTICAL,0, 1000);
以下是创建垂直进度条的示例 −
示例
package my;
import java.awt.Color;
import javax.swing.*;
public class SwingDemo extends JFrame {
JProgressBar progressBar;
int i = 0;
SwingDemo() {
progressBar = new JProgressBar(JProgressBar.VERTICAL,0, 1000);
progressBar.setBounds(70, 50, 120, 30);
progressBar.setValue(0);
progressBar.setStringPainted(true);
add(progressBar);
setSize(550, 150);
setLayout(null);
}
public void inc() {
while (i <= 1000) {
progressBar.setValue(i);
i = i + 50;
try {
Thread.sleep(100);
} catch (Exception e) {}
}
}
public static void main(String[] args) {
SwingDemo s = new SwingDemo();
s.setVisible(true);
s.inc();
}
}
输出
