inserting folder containing components into JList

Question

Can anyone guide me or give an example of how to insert components, or files of components, or their folder into JList. This has being an issue pending, please assist.

Answer 1

List<File> files = ... // Obtain files from somewhere ...

// Pass files as an array to JList.  Could alternatively implement custom ListModel.
Object[] arr = files.toArray();   
JList jl = new JList(arr);

// Define renderer to display full file names:
jl.setCellRenderer(new DefaultListCellRenderer() {
  public void getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) {

    File file = (File)value;
    return super.getListCellRendererComponent(list, file.getPath(), index, isSelected, cellHashFocus);
  }
});
