    JFileChooser Actionlistener


    While programming in Java i ran into a problem concerning a JFileChooser and it's actionListener.

    The problem is, that my Actionlistener only seems to listen to the events made by my JFileChoosers 'close' button.

    As you can see in my actionlistener im printing a line which should display "Display Test".

    But this only happens when i click the close button, and not when i use the open button.

    I would appriciate any help you can give me.

    //Java Code FileChooser.java
    package View;
    import Controller.CFileChooser;
    import java.awt.Container;
    import java.awt.event.ActionListener;
    import java.awt.event.ActionEvent;
    import javax.swing.JFrame;
    import javax.swing.JPanel;
    import javax.swing.JButton;
    import javax.swing.JFileChooser;
    import javax.swing.JLabel;
    public class FileChooser
    			extends		JFrame
    			implements	ActionListener
    	// GUI
        private JFileChooser FSFileChooser;
    	// Instantievariabele
            private CFileChooser _controller;
    	public FileChooser(CFileChooser controller)
            _controller = controller;
    		// Geef het frame een titel en zet de afmetingen
    		setTitle("Pick your *.leg File!");
    		Container pane = getContentPane();
    	FSFileChooser = new JFileChooser();
        public void actionPerformed(ActionEvent e)
            System.out.println("Display Test");
            //String command = e.getActionCommand();
            //if (command.equals(JFileChooser.CANCEL_SELECTION)) {
            //  System.out.println(JFileChooser.CANCEL_SELECTION);
    //End Java Code

    Greetings Dennis

    Use code tags, please.

    JFileChooser is a dialog. Therefore, it returns its results as an int value, as like in the following

    JFileChooser fc = new JFileChooser();
    int returnval = fc.showOpenDialog();
    if (returnval == JFileChooser.APPROVE_OPTION) {
     //user selected a file
    //do other options if needed

    I seem to have found the problem.

    It was stupid realy.

    My Code seemed to be correct, the only reason it did not work, is that i did not have a file selected.

    so the Open button in JFileChooser wont work if you dont have a file selected.

    Seems reasonable - how could it open a non-existent file?
