如何在没有JFileChooser的Java Swing中打开文件

Question

I'm using Java Swing (GUI) and I want to add a button to my project for opening files.

I don't like the JFileChooser since it opens a small window for browsing through the files of the directories. Can I use something else instead of the JFileChooser under Java Swing ?

I've tried to use elements of SWT but it didn't work, meaning is the use of the button object and then use it inside the JFrame , but that failed, so I guess SWT and Swing don't mix together?

Here is the example of Java Swing with JFileChooser and I'm looking for something like this to put in my JFrame .

Answer 1

JFileChooser with the native PLAF seems to fulfill the stated requirement.

import javax.swing.JFileChooser;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;

public class NativeFileChooser {

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(
                            UIManager.getSystemLookAndFeelClassName());
                } catch(Exception e) {
                    e.printStackTrace();
                }
                JFileChooser jfc = new JFileChooser();
                jfc.showOpenDialog(null);
            }
        });
    }
}

Still not quite to your liking? Then you might start with this one & change it to need:

..so I guess SWT and Swing don't mix together?

It is generally not a good idea to mix Swing/AWT/SWT components in the same top-level container . It is not a problem to open an AWT FileDialog over a Swing based JFrame since they are both top-level containers. I am pretty sure the same would apply to Swing/SWT or AWT/SWT.

Answer 2

If you do not need the flexibility of the JFileChooser , you can opt for the FileDialog which uses the native OS file dialog. See also Code ranch topic and this answer on SO
