JInternalFrame 向标题栏添加图标

Question

I'd like to add an ImageIcon or comparable to a JInternalFrame 's titlebar such that the [x] icon is east-most, the iconable icon is second east-most, and a custom icon is third east-most. Is this doable?

Answer 1

This worked for me:

ImageIcon icon = new ImageIcon(ClassLoader.getSystemResource("Iconos/icono.png"));
this.setFrameIcon(icon);

Answer 2

for get for parent frame : // parent 是容器 jDesktopPane -> parent = new JFrame ()

this.setFrameIcon(new javax.swing.ImageIcon(this.parent.getIconImage()));

Answer 3

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
}
