How can I start the JFileChooser in the Details view?

问题

I would like my JFileChooser to start in details view, instead of the "List" view that it starts in. How do you do that?

回答1:

You can get the Action from the ActionMap:

JFrame frame = new JFrame();
JFileChooser  fileChooser = new JFileChooser(".");
Action details = fileChooser.getActionMap().get("viewTypeDetails");
details.actionPerformed(null);
fileChooser.showOpenDialog(frame);

This is a little tricky and probably not officially supported, but I found out how to do this. First, you need to get the FilePane that the JFileChooser has. The only way I know how to do that is to traverse its components and then do an instanceof FilePane until you get it. Then this will start in Details view:

    if (root instanceof FilePane) {
        FilePane filePane = (FilePane) root;
        Action viewTypeAction = filePane.getViewTypeAction(FilePane.VIEWTYPE_DETAILS);
        viewTypeAction.actionPerformed(null);
    }
