Is there a way to disable the maximize button in a Window? You can use the index to look up the setResizable method (links at top of any api page) to find which classes have it. Frame and Dialog yes, Window no. Is there also a way to disable the close box on a modal JDialog and force the user to use a JButton to dismiss the dialog (yet still have a title bar)? Probably. You might have to write some plaf code. Other options: 1 — use a JWindow or undecorated JFrame and add or draw a "title bar" 2 — use a JOptionPane which will return null if the dialog is disposed with the close button 3 — add a WindowListener to the dialog and do what you need before the dialog is disposed.
