JFilerChooser default filefilter

Mar 24th, 2007

Hi, does anyone know how to set a JFileChoosers default filter back to accept all files after custom filters have been added?

Thanks.

Surely it would be something on the lines of changing the *.txt filter back to "*."

Although that's just me thinking out aloud.

JFileChooser has a setFileFilter(FileFilter filter) method. I could call this by putting any of my custom filters in but i don't have an identifier for the default one. So basically i'm just wonding what the default identifier is.

Well surely the default filter must be *.*.

Which I would imagine was derived from a regular expression? But I don't have my java compiler at hand to test that. And the API for JFilterChooser may not include that.

but the setFileFilter method requires a FileFilter identifier not a String.

for example:

ExtensionFileFilter filter = new ExtensionFileFilter(text, "*.txt");
fileChooser.addChooseableFileFilter(filter);
chooser.setFileFilter(filter);

perhaps i'm misunderstanding.

/** Filter to work with JFileChooser to select java file types. **/
public class JavaFilter extends javax.swing.filechooser.FileFilter
{
  public boolean accept (File f) {
    return f.getName ().toLowerCase ().endsWith ("*.*")
          || f.isDirectory ();
  }
  
  public String getDescription () {
    return "Java files (*.*)";
  }
} // class JavaFilter

Perhaps? Untested. Although I'd imagine it to be something along those lines?
