SYNOPSIS

       Inherits QEvent.

   Public Members
       QCloseEvent ()
       bool isAccepted () const
       void accept ()
       void ignore ()

DESCRIPTION
       The QCloseEvent class contains parameters that describe a close event.

       Close events are sent to widgets that the user wants to close, usually
       by choosing "Close" from the window menu, or by clicking the `X'
       titlebar button. They are also sent when you call QWidget::close() to
       close a widget programmatically.

       Close events contain a flag that indicates whether the receiver wants
       the widget to be closed or not. When a widget accepts the close event,
       it is hidden (and destroyed if it was created with the
       WDestructiveClose flag). If it refuses to accept the close event
       nothing happens. (Under X11 it is possible that the window manager will
       forcibly close the window; but at the time of writing we are not aware
       of any window manager that does this.)

       The application's main widget -- QApplication::mainWidget() -- is a
       special case. When it accepts the close event, Qt leaves the main event
       loop and the application is immediately terminated (i.e. it returns
       from the call to QApplication::exec() in the main() function).

       The event handler QWidget::closeEvent() receives close events. The
       default implementation of this event handler accepts the close event.
       If you do not want your widget to be hidden, or want some special
       handing, you should reimplement the event handler.

       The closeEvent() in the Application Walkthrough shows a close event
       handler that asks whether to save a document before closing.

       If you want the widget to be deleted when it is closed, create it with
       the WDestructiveClose widget flag. This is very useful for independent
       top-level windows in a multi-window application.

       QObjects emits the destroyed() signal when they are deleted.

       If the last top-level window is closed, the
       QApplication::lastWindowClosed() signal is emitted.

       The isAccepted() function returns TRUE if the event's receiver has
       agreed to close the widget; call accept() to agree to close the widget
       and call ignore() if the receiver of this event does not want the
       widget to be closed.

       See also QWidget::close(), QWidget::hide(), QObject::destroyed(),
       QApplication::setMainWidget(), QApplication::lastWindowClosed(),
       QApplication::exec(), QApplication::quit(), and Event Classes.

MEMBER FUNCTION DOCUMENTATION
QCloseEvent::QCloseEvent ()
       Constructs a close event object with the accept parameter flag set to
       FALSE.

       See also accept().

void QCloseEvent::accept ()
       Sets the accept flag of the close event object.

       Setting the accept flag indicates that the receiver of this event
       agrees to close the widget.

       The accept flag is not set by default.

       If you choose to accept in QWidget::closeEvent(), the widget will be
       hidden. If the widget's WDestructiveClose flag is set, it will also be
       destroyed.

       See also ignore() and QWidget::hide().

       Examples:

void QCloseEvent::ignore ()
       Clears the accept flag of the close event object.

       Clearing the accept flag indicates that the receiver of this event does
       not want the widget to be closed.

       The close event is constructed with the accept flag cleared.

       See also accept().

       Examples:

bool QCloseEvent::isAccepted () const
       Returns TRUE if the receiver of the event has agreed to close the
       widget; otherwise returns FALSE.

       See also accept() and ignore().
