Can you return user action from ActionEvent?

[codybrees]

Hello, I am working on a program and trying to add a GUI to it. I want the user to chose a directory for files to be run into the program. I am using a separate class for the GUI and I cant seem to pass the anything from ActionEvent to my main. Is this possible? My code is below. Any help or advice at all would be greatly appreciated.

public class GUIOptions extends JPanel
implements ActionListener {
	static private final String newline = "\n";
	JButton openButton;
	JTextArea log;
	JFileChooser fc;

	public GUIOptions() {		
		
			super(new BorderLayout());

			log = new JTextArea(25,50);
			log.setMargin(new Insets(5,5,5,5));
			log.setEditable(false);
			JScrollPane logScrollPane = new JScrollPane(log);
			fc = new JFileChooser();
			//fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
			fc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
			openButton = new JButton("Chose a directory");
			openButton.addActionListener(this);
			JPanel buttonPanel = new JPanel(); 
			buttonPanel.add(openButton);
			add(buttonPanel, BorderLayout.PAGE_START);
			add(logScrollPane, BorderLayout.CENTER);
		}



public void actionPerformed(ActionEvent e) {

//Handle open button action.
if (e.getSource() == openButton) {
	int returnVal = fc.showOpenDialog(GUIOptions.this);

	if (returnVal == JFileChooser.APPROVE_OPTION) {
		File file = fc.getSelectedFile();
		log.append("Opening: " + file.getName() + "." + newline);
	//	File[] testFiles = fc.getSelectedFiles();
		//return testFiles;
	} else {
		log.append("Open command cancelled by user." + newline);
	}
	log.setCaretPosition(log.getDocument().getLength());
}
	 
} 

public static void createAndShowGUI() {
    JFrame frame = new JFrame("TestMiningGui");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    frame.add(new GUIOptions());
    frame.pack();
    frame.setVisible(true);
}

public static void main(String[] args) {
	 createAndShowGUI();
            
	File[] testFiles = getFileListFromDirectory(This is where I cant get it to call the user specified directory);

Your GUIOptions class doesn't have a method getFileListFromDirectory() and if it did it would have to be an instance method as the FileChooser is called from an instance method. This means your main method would need a reference to the GUIOptions instance so it can call the method. You also need an instance attribute to keep a record of what file/dir was selected so you can generate the file list.
