在面板中添加一个复杂的图像，在一个自定义的用户界面中，周围有button

我怎么能像这样的形象像下面到slavePanel和顶部的JPanel调整slavePanel看起来像图像，但正确包装button？ （现在它们被塑造成一排，四列）

  // // Shot Gun mover up/down/left/right, middle on is for zoom // public void GunMover(JPanel configPanel) throws IOException { // Master Panel - holds everything JPanel masterPanel = new Panel(); masterPanel.setLayout(new SpringLayout()); // Slave Panel - with image background JPanel slavePanel = new Panel(); slavePanel.setLayout(new SpringLayout()); // Row 1 final JButton ptzLeft = new JButton("<"); masterPanel.add(ptzLeft, BorderLayout.WEST); // Row 2 final JButton ptzRight = new JButton(">"); masterPanel.add(ptzRight, BorderLayout.CENTER); // Row 3 final JButton ptzUp = new JButton("^"); masterPanel.add(ptzUp, BorderLayout.WEST); // Row 4 final JButton ptzDown = new JButton("down"); masterPanel.add(ptzDown, BorderLayout.CENTER); // How do i add slavePanel this background and add all the JButtons // According to that image shape? // Layout the panel. SpringUtilities.makeCompactGrid(masterPanel, 1, 4, //rows, cols 6, 6, //initX, initY 6, 6); configPanel.setLayout(new GridLayout(0,1)); configPanel.add(masterPanel); }

1. 使用3×3 GridLayout
2. 对于9个细胞的每一个获得一个子图像：
   • 对于每个第二个组件，添加一个带有子图像的标签。
   • 对于其他每个组件，添加一个从中删除空间的JButton 。 使用子图像作为图标，但您需要备用图标来指示焦点，激活等。此示例在“按下”图标周围放置红色边框。

 import java.awt.*; import java.awt.event.*; import java.awt.image.BufferedImage; import javax.swing.*; import java.io.IOException; import java.net.URL; import javax.imageio.ImageIO; public class CompassButtons { public CompassButtons(BufferedImage bi) { int w = bi.getWidth(); int h = bi.getHeight(); int step = w/3; JPanel p = new JPanel(new GridLayout(3,3)); p.setOpaque(false); int count = 0; for (int ii=0; ii<w; ii+=step) { for (int jj=0; jj<h; jj+=step) { // This is it - GET THE SUB IMAGE Image icon = bi.getSubimage(jj, ii, step, step); if (count%2==1) { JButton button = new JButton(new ImageIcon(icon)); // remove the border - indicate action using a different icon button.setBorder(null); // make a 'pressed' icon.. BufferedImage iconPressed = new BufferedImage(step,step,BufferedImage.TYPE_INT_ARGB); Graphics g = iconPressed.getGraphics(); g.drawImage(icon, 0, 0, p); g.setColor(Color.RED); g.drawRoundRect( 0, 0, iconPressed.getWidth(p)-1, iconPressed.getHeight(p)-1, 12, 12); g.dispose(); button.setPressedIcon(new ImageIcon(iconPressed)); // make it transparent button.setContentAreaFilled(false); button.setActionCommand(""+count); button.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent ae) { System.out.println(ae.getActionCommand()); } }); p.add(button); } else { JLabel label = new JLabel(new ImageIcon(icon)); p.add(label); } count++; } } JPanel center = new JPanel(new GridBagLayout()); center.setBackground(Color.BLACK); center.add(p); JOptionPane.showMessageDialog(null, center); } public static void main(String[] args) throws IOException { URL url = new URL("http://i.stack.imgur.com/SNN04.png"); final BufferedImage bi = ImageIO.read(url); SwingUtilities.invokeLater(new Runnable(){ @Override public void run() { new CompassButtons(bi); } }); } } 

Answer 2

从这个例子开始，我通过像这样改变MoveButton开始：

 this.setBorderPainted(false); 

你可以给ControlPanel一个自定义布局pipe理器 。 我还要添加一个背景图片和一些基于ButtonModel状态的视觉反馈，就像这里所build议的那样。

Answer 3

1）你必须准备的图标之前和每5个JButtons （ 事件来自ButtonModel ）

• 基本图标没有焦点

• isRollover()图标

• isPressed()图标

2） 如何设置图标，并从JButton中删除所有“balast”

3）把这5 JButtons放到JPanel上5 JButtons （RemoteSet）
