Question

I disable the new Folder button using the following code:

 public void disableNewFolderButton( Container c ) {

     System.out.print("in disable fn");
int len = c.getComponentCount();
for (int i = 0; i < len; i++) {
  Component comp = c.getComponent(i);
  if (comp instanceof JButton) {
    JButton b = (JButton)comp;
    Icon icon = b.getIcon();
    if (icon != null
         && icon == UIManager.getIcon("FileChooser.newFolderIcon"))
    {
        System.out.print("in disable fn");
       b.setEnabled(false);
    }
    }
  else if (comp instanceof Container) {
    disableNewFolderButton((Container)comp);
  }
}
 }

The code is called in the following lines:

   JFileChooser of=new JFileChooser();
    of.setAcceptAllFileFilterUsed(false);
    of.addChoosableFileFilter(new MyFilter());
    disableNewFolderButton(of);

But the new folder button is disabled only when the file chooser is first displayed. Suppose i go to some drive , say g: , then the button is enabled again. How to set this right?

Answer 1

this is working for me…

    //Create a file chooser
UIManager.put("FileChooser.readOnly", Boolean.TRUE); 
JFileChooser fc = new JFileChooser();
