How to get the linux folder and file icons and names in java?

Question

I'm creating a tree of folders and files in java. Windows and OSX return the system icons and name with the following code:

new JFileChooser().getIcon(File f);
new JFileChooser().getName(File f);

Is there any possibility to get the icons and name of unix systems?. A system command would be ok too.

Thanks.

Answer 1

I did not tested but this code should work on most systems:

FileSystemView view = FileSystemView.getFileSystemView();
Icon icon = view.getSystemIcon(file);

Answer 2

can't add a comment, so posting as an answer :

Have a look at http://stackoverflow.com/questions/1629172/how-do-you-get-the-icon-mime-type- and-application-associated-with-a-file-in-the

All those answers will make you get your hands dirty in C or C++ though. Java never really rhymed with native look and feel...

Answer 3

You can always get the name of the system you are working on, Java allows you to do a native execution and capture the results of this (command line, so for unix flavors, Runtime.exec("uname -a");) then parse the results in the output stream.

Having said that, there are a number of different implementations of GUI layers on top of a unix kernel, and there is not a standard way of retrieving the mappings between file types and icon images. You can make a solution specific to a window manager, but would need to change your algorithm based on which wm is being used.
