JInternalFrame 添加图标到标题栏

Question

我想添加一个ImageIcon或类似于 aJInternalFrame的标题栏，这样 [x] 图标在最东边，可图标图标在第二个最东边，自定义图标在第三个最东边。这是可行的吗？

Answer 1

JInternalFrame jInternalFrame1 = new JInternalFrame("Test Internal Frame",false,false,false,false);

try {
  URL url = new URL("images/icon.gif");
  ImageIcon icon = new ImageIcon(url);
  jInternalFrame1.setFrameIcon(icon);
} 
catch (MalformedURLException ex) 
{
   //whatever you want to put here
}
