使用用户指定的计时器更新gui中的JPanel和属性？

Question

所以我有这个班。我们将其称为ProcessBox。我有另一个叫Process的类，它有一个ProcessBox作为成员变量。然后，在我的主要方法中，我有一个ProcessList对象的ArrayList（每个对象都有自己的ProcessBox）。我将如何去做，以便我的ProcessBox会更新每个x毫秒（其中x是用户指定的，我已经有用于输入x的侦听器）。以下是我的ProcessBox类。这是我希望重绘每x毫秒（除了它们的整个列表）。

import java.awt.*; 

import javax.swing.*; 
import javax.swing.border.LineBorder; 

import java.util.*; 

public class ProcessBox extends JPanel { 
    GridBagLayout gbc_panel; 

    public ProcessBox(Process p) { 
     super(new GridBagLayout()); 
     gbc_panel = new GridBagLayout(); 
     gbc_panel.columnWidths = new int[] { 0, 0, 0 }; 
     gbc_panel.rowHeights = new int[] { 0, 0, 0, 0, 0, 0 }; 
     gbc_panel.columnWeights = new double[] { 0, 0, Double.MIN_VALUE }; 
     gbc_panel.rowWeights = new double[] { 0.0, 0.0, 0.0, 0.0, 0.0, 
       Double.MIN_VALUE }; 
     super.setLayout(gbc_panel); 


     setPreferredSize(new Dimension(110, 110)); 
     setMinimumSize(new Dimension(110, 110)); 
     setAlignmentX(Component.LEFT_ALIGNMENT); 
     setBorder(new LineBorder(new Color(0, 0, 0), 1)); 
     setSize(new Dimension(110, 110)); 

     String name = p.getName(); 
     int priority = p.getPriority(); 
     int minPriority = p.getMinPriority(); 
     ArrayList<Integer> times = p.getTime(); 
     Random r = new Random(System.currentTimeMillis()); 
     setBackground(new Color(r.nextInt(255 - 210) + 210, 
       r.nextInt(255 - 210) + 210, r.nextInt(255 - 210) + 210)); 

     JLabel lblNewLabel = new JLabel("ID:"); 
     GridBagConstraints gbc_lblNewLabel = new GridBagConstraints(); 
     gbc_lblNewLabel.gridheight = 2; 
     gbc_lblNewLabel.insets = new Insets(0, 0, 5, 5); 
     gbc_lblNewLabel.gridx = 0; 
     gbc_lblNewLabel.gridy = 0; 
     add(lblNewLabel, gbc_lblNewLabel); 

     JLabel lblNewLabel_1 = new JLabel(name); 
     GridBagConstraints gbc_lblNewLabel_1 = new GridBagConstraints(); 
     gbc_lblNewLabel_1.gridheight = 2; 
     gbc_lblNewLabel_1.insets = new Insets(0, 0, 5, 0); 
     gbc_lblNewLabel_1.gridx = 1; 
     gbc_lblNewLabel_1.gridy = 0; 
     add(lblNewLabel_1, gbc_lblNewLabel_1); 

     JLabel lblNewLabel_2 = new JLabel("Priority:"); 
     GridBagConstraints gbc_lblNewLabel_2 = new GridBagConstraints(); 
     gbc_lblNewLabel_2.insets = new Insets(0, 0, 5, 5); 
     gbc_lblNewLabel_2.gridx = 0; 
     gbc_lblNewLabel_2.gridy = 2; 
     add(lblNewLabel_2, gbc_lblNewLabel_2); 

     JLabel lblNum = new JLabel(Integer.toString(priority)); 
     GridBagConstraints gbc_lblNum = new GridBagConstraints(); 
     gbc_lblNum.insets = new Insets(0, 0, 5, 0); 
     gbc_lblNum.gridx = 1; 
     gbc_lblNum.gridy = 2; 
     add(lblNum, gbc_lblNum); 

     JLabel lblNewLabel_3 = new JLabel("Min:"); 
     GridBagConstraints gbc_lblNewLabel_3 = new GridBagConstraints(); 
     gbc_lblNewLabel_3.insets = new Insets(0, 0, 5, 5); 
     gbc_lblNewLabel_3.gridx = 0; 
     gbc_lblNewLabel_3.gridy = 3; 
     add(lblNewLabel_3, gbc_lblNewLabel_3); 

     JLabel lblMp = new JLabel(Integer.toString(minPriority)); 
     GridBagConstraints gbc_lblMp = new GridBagConstraints(); 
     gbc_lblMp.insets = new Insets(0, 0, 5, 0); 
     gbc_lblMp.gridx = 1; 
     gbc_lblMp.gridy = 3; 
     add(lblMp, gbc_lblMp); 

     JLabel lblTimeSlice = new JLabel("Slice:"); 
     GridBagConstraints gbc_lblTimeSlice = new GridBagConstraints(); 
     gbc_lblTimeSlice.insets = new Insets(0, 0, 0, 5); 
     gbc_lblTimeSlice.gridx = 0; 
     gbc_lblTimeSlice.gridy = 4; 
     add(lblTimeSlice, gbc_lblTimeSlice); 

     JLabel lblLeft = new JLabel(Integer.toString(times.get(0))); 
     GridBagConstraints gbc_lblLeft = new GridBagConstraints(); 
     gbc_lblLeft.gridx = 1; 
     gbc_lblLeft.gridy = 4; 
     add(lblLeft, gbc_lblLeft); 
     setVisible(true); 

}
