How to close parent frame from JInternalFrame in java?

I want to close the parent frame on the click of a button in JInternalFrame.

Solution

  • Parent frame as the JInternalFrame the button is in or the JFrame or window it is contained in? Use either:

    SwingUtilities.getWindowAncestor(button).dispose()

    or

    SwingUtilities.getAncestorOfClass(JInternalFrame.class, button).dispose();

    or similar.
