How to use the default File Chooser for the operating system? java

问题

I was just wondering: how does Gmail use the Windows/Mac file chooser to upload files? Is there any way to do this in Java?

Personally, I don't like the way that the JFileChooser looks like, and I thought it would be better for my users to be able to use something that they're more used to. Tips anyone?

回答1:

Use the old java.awt.FileDialog instead:

new java.awt.FileDialog((java.awt.Frame) null).setVisible(true);

回答2:

You can try using JFileChooser but setting the look and feel to be the platform look and feel:

    try {
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    }catch(Exception ex) {
        ex.printStackTrace();
    }

And that would make all the swing components look nicer!

GMail is a web application that eventually relies on the browser to show this component. Now a good solution is to use the Native Look&Feel of the system which provides a JFileChooser quite similar to what you show:

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

EDIT: Pulsar's solution is even better since it provides the exact dialog you are looking for. I am not sure that it provides all the features of the JFileChooser.

The SWT components have always looked the same styles that are in the running OS. You can see some examples:

File Dialog Example : Dialog « SWT JFace Eclipse « Java
eclipse.platform.swt.git - Eclipse SWT

It was assumed that from version 7 of Java, Swing styles would be more like that of operating systems, but may see it in Java 8.
