They are also sent when you call +<a href="qwidget.html#close">TQWidget::close</a>() to close a widget programmatically. +<p> 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 <a href="qt.html#WidgetFlags-enum">WDestructiveClose</a> 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.) +<p> The application's main widget -- <a href="qapplication.html#mainWidget">TQApplication::mainWidget</a>() -- +is a special case. When it accepts the close event, TQt leaves the +main event loop and the application is immediately terminated +(i.e. it returns from the call to <a href="qapplication.html#exec">TQApplication::exec</a>() in the +main() function). +<p> The event handler <a href="qwidget.html#closeEvent">TQWidget::closeEvent</a>() 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. +<p> The <a href="simple-application.html#closeEvent">closeEvent() in the + Application Walkthrough</a> shows a close event handler that +asks whether to save a document before closing. +<p> If you want the widget to be deleted when it is closed, create it +with the <a href="qt.html#WidgetFlags-enum">WDestructiveClose</a> widget flag. This is very useful for +independent top-level windows in a multi-window application. +<p> <a href="qobject.html">TQObject</a>s emits the <a href="qobject.html#destroyed">destroyed()</a> signal when they are deleted. +<p> If the last top-level window is closed, the +<a href="qapplication.html#lastWindowClosed">TQApplication::lastWindowClosed</a>() signal is emitted. +<p> The <a href="#isAccepted">isAccepted</a>() function returns TRUE if the event's receiver has +agreed to close the widget; call <a href="#accept">accept</a>() to agree to close the +widget and call <a href="#ignore">ignore</a>() if the receiver of this event does not +want the widget to be closed. +<p> <p>See also <a href="qwidget.html#close">TQWidget::close</a>(), <a href="qwidget.html#hide">TQWidget::hide</a>(), <a href="qobject.html#destroyed">TQObject::destroyed</a>(), <a href="qapplication.html#setMainWidget">TQApplication::setMainWidget</a>(), <a href="qapplication.html#lastWindowClosed">TQApplication::lastWindowClosed</a>(), <a href="qapplication.html#exec">TQApplication::exec</a>(), <a href="qapplication.html#tquit">TQApplication::tquit</a>(), and <a href="events.html">Event Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQCloseEvent"></a>TQCloseEvent::TQCloseEvent () +</h3> + +<p> Constructs a close event object with the accept parameter flag set +to FALSE. +<p> <p>See also <a href="#accept">accept</a>(). + +<h3 class=fn>void <a name="accept"></a>TQCloseEvent::accept () +</h3> + +<p> Sets the accept flag of the close event object. +<p> Setting the accept flag indicates that the receiver of this event +agrees to close the widget. +<p> The accept flag is <em>not</em> set by default. +<p> If you choose to accept in <a href="qwidget.html#closeEvent">TQWidget::closeEvent</a>(), the widget will +be hidden.
