java - 将包含组件的文件夹插入到 JList 中

Question

任何人都可以指导我或举例说明如何将组件、组件文件或其文件夹插入到 JList 中。这是一个悬而未决的问题，请协助。

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);
  }
});
