this one helps. I have a Java assignment in which I need to build a program for exchanging information between students. I am using IntelliJ IDEA and a plugin called JFormDesigner for designing the GUI. I want do display a file chooser when clicking on a button. I have tried different implementations but non of them works. Nothing is displayed on the screen when clicking the button I was wondering if someone could help me find a solution. , Choose another listener
code :
ChooseButton1.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        ChooseButton1MouseClicked(e);
    }
});

I wish this help you The GUI system can only do one thing at a time, like most code (except for code that uses threads). Calling your listener is a thing. The GUI system cannot do anything else while your listener is running.
Your database operation needs to run on another thread (which you can create) and then update the GUI when it's done. Something like this:
code :
void onButtonPressed() {
    // The code to open the file dialog goes here

    button.setText("");
    ImageIcon progressbar = new     
        ImageIcon(DatasetExporterUI.class.getResource("/progreassbar.gif"));
        buttonExport.setIcon(progressbar);

    new Thread() {
        @Override
        public void run() {
            // do some database operations here

            EventQueue.invokeLater(new Runnable() {
                @Override
                public void run() {
                    //again remove icon from button
                    button.setIcon(null);
                    button.setText("click");
                }
            });
        }
    }.start();
}

hop of those help? As was mentioned, you need to call frame.revalidate(); after you add the new component.
You also should call image.setPreferredSize(new Dimension(500, 500)); or similar to ensure that your image isn't tiny.

code :
FileInputStream fIS = getApplicationContext().openFileInput(fileName);
FileInputStream fIS = new FileInputStream(fileName);

Hope that helps You could use a Hashmap. The key would be the text (or however you uniquely identify the button) of the button and the value would be the button.
