使用 setBounds() 方法在 Java Swing 中设置 JProgressBar 的边界 −
JProgressBar progressBar; progressBar.setBounds(70, 50, 120, 30);
以下是设置 JProgressBar 边界的示例 −
示例
package my;
import javax.swing.*;
public class SwingDemo extends JFrame {
JProgressBar progressBar;
int i = 0;
SwingDemo() {
progressBar = new JProgressBar(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();
}
}
输出显示一个完全填充的 ProgessBar −
