我如何實現一個具有多行按鈕間隔相等的多個按鈕的GUI GUI

Question

我想要在頂行上獲得4個按鈕，在底行上獲得4個按鈕，並且我需要一個下面的按鈕 - 這是一個投票應用程序，每個按鈕代表一個候選人。 initializeThings（）是從此applet的init方法調用的唯一方法。 Person類只是一個3字符串的容器，代表名稱，候選人的位置以及其他關於它們的信息。我的主要問題是隻想弄清楚如何使用最上面一行的4個按鈕，最下面的4個按鈕和最下面一行下面的投票按鈕進行格式化。

public class MainElectionWindow extends JApplet implements ActionListener, MouseListener{ 
private JPanel panel, topRow, bottomRow, voteBtnRow; 
private JButton person1But,person2But,person3But,person4But,person5But,person6But,person7But,person8But,castVote; 
private Person person1,person2,person3,person4,person5,person6,person7,person8; 
private ImageIcon pic1, pic2, pic3, pic4, pic5, pic6, pic7, pic8; 

private static final int HORIZONTAL_SPACING = 10; 
private static final int VERTICAL_SPACING = 20; 


private void initializeThings() { 


// Initialize variables 
topRow = new JPanel(); 
topRow.setLayout(new BoxLayout(topRow,BoxLayout.X_AXIS)); 

bottomRow = new JPanel(); 
bottomRow.setLayout(new BoxLayout(bottomRow,BoxLayout.X_AXIS)); 

voteBtnRow = new JPanel(); 


//Create people with names, position they're running for, and other info 
person1 = new Person("Name 1", "Pos 1", "Other Info 1"); 
person2 = new Person("Name 2", "Pos 2", "Other Info 2"); 
person3 = new Person("Name 3", "Pos 3", "Other Info 3"); 
person4 = new Person("Name 4", "Pos 4", "Other Info 4"); 
person5 = new Person("Name 5", "Pos 5", "Other Info 5"); 
person6 = new Person("Name 6", "Pos 6", "Other Info 6"); 
person7 = new Person("Name 7", "Pos 7", "Other Info 7"); 
person8 = new Person("Name 8", "Pos 8", "Other Info 8"); 

pic1 = new ImageIcon("facebackground.png"); 
pic2 = new ImageIcon("facebackground.png"); 
pic3 = new ImageIcon("facebackground.png"); 
pic4 = new ImageIcon("facebackground.png"); 
pic5 = new ImageIcon("facebackground.png"); 
pic6 = new ImageIcon("facebackground.png"); 
pic7 = new ImageIcon("facebackground.png"); 
pic8 = new ImageIcon("facebackground.png"); 


// Get the content pane 
Container container = this.getContentPane(); 

// Add panel to container 
container.add(topRow); 
container.add(bottomRow); 
container.add(voteBtnRow); 

person1But = new JButton(pic1); 
person2But = new JButton(pic2); 
person3But = new JButton(pic3); 
person4But = new JButton(pic4); 
person5But = new JButton(pic5); 
person6But = new JButton(pic6); 
person7But = new JButton(pic7); 
person8But = new JButton(pic8); 
castVote = new JButton("Vote"); 

// Add action listeners 
person1But.addActionListener(this); 
person2But.addActionListener(this); 
person3But.addActionListener(this); 
person4But.addActionListener(this); 
person5But.addActionListener(this); 
person6But.addActionListener(this); 
person7But.addActionListener(this); 
person8But.addActionListener(this); 
castVote.addActionListener(this); 

//Add Mouse Listeners 
person1But.addMouseListener(this); 
person2But.addMouseListener(this); 
person3But.addMouseListener(this); 
person4But.addMouseListener(this); 
person5But.addMouseListener(this); 
person6But.addMouseListener(this); 
person7But.addMouseListener(this); 
person8But.addMouseListener(this); 


// Add components to the visual panel1 
topRow.add(person1But); 
topRow.add(person2But); 
topRow.add(person3But); 
topRow.add(person4But); 
bottomRow.add(person5But); 
bottomRow.add(person6But); 
bottomRow.add(person7But); 
bottomRow.add(person8But); 
voteBtnRow.add(castVote); 


// Make it visible 
//person1But.requestFocusInWindow(); 

add(container); 

setVisible(true); 
}

Answer 1

我建議你看一看GridBagLayout，一旦你弄清楚如何使用它，您的用戶界面將是很容易做到。

Answer 2

你可以看看TableLayoutManager，我並不是那種經驗豐富的使用Java的人，但是在學校我喜歡使用它。

也嘗試循環的人，圖片等，簡化代碼
