I intend to populate a JFileChooser with names from a database but use the standard JFileChooser Dialog for load, delete, save and save-as. I want to give users an impression that they are working on a file system whereas am using a database at the backend to save changes. The user should not be able to browse to a different directory to save or save as. I want to use the same JFileChooser Dialog but with a cancel button and another button(delete|save|save as|load).

推荐答案

无法使用JFileChooser完成.

Can't be done using the JFileChooser.

JFileChooser仅在java.io.File上运行.为此，您必须继承java.io.File的子类，并创建某种非常丑陋的假文件系统.

JFileChooser only operates on java.io.File's. To do this you would have to subclass java.io.File and create some kind of fake file system that would be very ugly.

您将必须制作自己的保存对话框组件或找到另一个要使用的类似组件. JFileChooser不是您想要的.

You are going to have to make your own save dialog component or find another similar component to use. JFileChooser isnt what you want.
