JFileChooser (Open File Dialog)

[Amit Nag]

How to make a Open File (JFileChooser) dialog
non-resizable? By default, it's resizable.

Good question.
I would suggest looking in the Swing code for JFileChooser at the method createDialog. It creates a JDialog and puts the file chooser panel into it at BorderLayout.CENTER. When you call showOpenDialog this calls showDialog and, in turn, createDialog.
So, either take your JFileChooser and put it inside a JDialog that you create and control (possibly copying code from Swing), or create a class (or inner class or anonymous class) that extends JFileChooser and override the createDialog method so that it sets the JDialog to be non-resizable.
Use setResizable(false) from java.awt.Dialog on the JDialog.
For example, (this is copied from jdk1.4.1):

JFileChooser myFileChooser = new JFileChooser(){
    protected JDialog createDialog(Component parent) throws HeadlessException {
        JDialog dialog = super.createDialog(parent);
        dialog.setResizable(false);
        return dialog;
    }
};

I haven't tried this code but my guess is it will work.
