JScrollPane pane;
public FileInformationForm() {
toInitialize();
Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
setBounds((dim.width-600)/2,(dim.height-510)/2,600,510);
setTitle("File Information");
setVisible(true);
}
private void toInitialize() {
txtInforamtion = new JTextArea();
pane = new JScrollPane(txtInforamtion);
getContentPane().setLayout(null);
getContentPane().add(pane);
txtInforamtion.setBackground(Color.black);
