java - 将图像添加到 GridLayout 中的单元格

Question

尝试创建一个 gridLayout 并用图像填充它，哪里出错了？

ImageIcon grassIcon = new ImageIcon("images/grass_tile.jpg"); 
JPanel panel = new JPanel(new GridLayout(haps,snaps,0,0));

JLabel labels[] = new JLabel[(haps*snaps)];

for (int i =  0; i < haps*snaps; i++)
{
    labels[i] = new JLabel(grassIcon);
    panel.add(labels[i]);
}

frame.add(panel);

Answer 1

使用frame.setVisible(true); 显示框架；

ImageIcon grassIcon = new ImageIcon("images/grass_tile.jpg"); 
JPanel panel = new JPanel(new GridLayout(haps,snaps,0,0));

JLabel labels[] = new JLabel[(haps*snaps)];

for (int i =  0; i < haps*snaps; i++)
{
      labels[i] = new JLabel(grassIcon );
      panel.add(labels[i]);
}

frame.add(panel);
frame.pack();
frame.setVisible(true);

Answer 2

如果正确，请尝试检查您的图像路径。或者，如果您真的可以使图像出现，则可以进行测试，尝试使其成为绝对路径。另外，请详细说明您的问题。

Answer 3

正如 ben75 所写，它需要 frame.pack(); 对他的信任！
