## Interface WindowConstants

- All Known Implementing Classes:
    JDialog, JFrame, JInternalFrame

      public interface WindowConstants

  Constants used to control the window-closing operation. The `setDefaultCloseOperation` and `getDefaultCloseOperation` methods provided by `JFrame`, `JInternalFrame`, and `JDialog` use these constants. For examples of setting the default window-closing operation, see Responding to Window-Closing Events, a section in The Java Tutorial.
  See Also:
    `JFrame.setDefaultCloseOperation(int)`, `JDialog.setDefaultCloseOperation(int)`, `JInternalFrame.setDefaultCloseOperation(int)`

          static final int DO_NOTHING_ON_CLOSE

      The do-nothing default window close operation.

        Constant Field Values

    - #### HIDE_ON_CLOSE

          static final int HIDE_ON_CLOSE

      The hide-window default window close operation

    - #### DISPOSE_ON_CLOSE

          static final int DISPOSE_ON_CLOSE

      The dispose-window default window close operation.

      Note: When the last displayable window within the Java virtual machine (VM) is disposed of, the VM may terminate. See AWT Threading Issues for more information.

      See Also:
        `Window.dispose()`, `JInternalFrame.dispose()`, Constant Field Values

    - #### EXIT_ON_CLOSE

          static final int EXIT_ON_CLOSE

      The exit application default window close operation. Attempting to set this on Windows that support this, such as `JFrame`, may throw a `SecurityException` based on the `SecurityManager`. It is recommended you only use this in an application.
