更改 swing 中 JFileChooser 的外观

Question

My requirement is to add check box with every directory which is shown by JFileChooser. and give multi selection facility.

How can I achieve this?

Answer 1

JFileChooser has multi-selection built in ( setMultiSelectionEnabled() ). It doesn't use checkboxes, but you can select multiple items.

Answer 2

I think it can be done this way. Override MetalFileChooserUI.createList() and return your own custom list panel. Therein, add checkbox renderers to the items in your list.

Answer 3

It would probably be easier to implement a custom component than alter a JFileChooser to support this (odd) requirement. You might start with altering the component used in File Manager questions .
