How to make output directory selection panel?

Question

Hi I am trying to make one pane that shows something like windows explorer in my computer. when user complete it\'s operations, and after that when he want to save edited image

Answer 1

You could have a look at JFileChooser. You can use this object to open a SaveDialog and get a save path on the local harddisk. Then eventually use an ObjectOutputStream to write a file.

Sample code:

    JFileChooser c = new JFileChooser();
    c.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
    // Demonstrate "Save" dialog:
    int rVal = c.showSaveDialog(fb);
    if (rVal == JFileChooser.APPROVE_OPTION) {
        System.out.println(c.getSelectedFile().toString());
    }

Answer 2

This can be handled with a JFileChooser, sorry if it's not the solution you're looking for

Note: you say choose a directory but I assume you mean that they can name their file

private File selectSaveFile() {
    JFileChooser fc = new JFileChooser();
    fc.setFileFilter(new FileNameExtensionFilter("File Type", "txt"));
    fc.setCurrentDirectory(new File(System.getProperty("user.home")));
    int returnVal = fc.showSaveDialog(frame);
    if (returnVal == JFileChooser.APPROVE_OPTION) {
        return fc.getSelectedFile();
    }
    //the user didn't click save if we are here
    return null;
}

Answer 3

Yes its possible. It's basically just JTree.

You will probably want to take a look at File#listRoots, File#isDirectory and File#listFiles.

You'll also want to take a look at How to use trees.

You'll probably also want to take a look at FileSystemView#getSystemIcon which will allow you to look an appropriate icon for the given File

However, it might be simpler to just use a JFileChooser ;)

Answer 4

A complete example using JTree is examined in FileBrowser.

An alternative using Outline is shown here.
