JFileChooser - multiple file filters?

Question

I have a question about the JFileChooser in Swing. I'm trying to get multiple file extensions in the drop-down box, but have no idea how to do it.

There is the method

extFilter = FileNameExtensionFilter(description, extensions);

that I can then use by writing

fileChooser.setFileFilter(extFilter);

however, as you can see, this only supports one option in the drop-down list. How do I add more?

I think you want the addChoosableFileFilter method. Read the tutorial.

You can simply create a filter that subclasses FileFilter and call the method I outlined above with that filter as an argument.

I'm sure you have already solved this to your satisfaction, but I came across this link at the same time I came across your question. In particular, look at section 3 for a way to generate multiple filters easily.

even tough this answer has more than 3 years was surprisingly useful, having a class extending the filechooser class to add your own behavior it's way useful! – Abstract Aug 23 '13 at 22:20

use

filter.addChoosableFileFilter(new FileNameExtensionFilter(description, extensions));

as many as the number of your extensions.

I know this question was asked long back, but one can take the following steps to define multiple extensions:

JFileChooser jfc = new JFileChooser(); jfc.setFileFilter(new FileNameExtensionFilter("Select XSL Files","xsl","xslt"));
