The fileSelectionMode property setting determines the mode of the chooser.
The available settings are specified by the three JFileChooser constants:
FILES_ONLY,
DIRECTORIES_ONLY, and
FILES_AND_DIRECTORIES.
Initially, the file chooser is in JFileChooser.FILES_ONLY mode.
To change the mode, just call public void setFileSelectionMode(int newMode).
import javax.swing.JFileChooser;
public class JFileChooserSelectionMode {
public static void main(String[] a) {
JFileChooser fileChooser = new JFileChooser();
fileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
fileChooser.showOpenDialog(null);
}
}
