You should call <a href="#ignore">QKeyEvent::ignore</a>() if the +key press or release event is not handled by your widget. A key event is +propagated up the parent widget chain until a widget accepts it with +<a href="#accept">QKeyEvent::accept</a>() or an event filter consumes it. +Key events for multi media keys are ignored by default. You should call +QKeyEvent::accept() if your widget handles those events. +<p> The QWidget::setEnable() function can be used to enable or disable +mouse and keyboard events for a widget. +<p> The event handlers <a href="qwidget.html#keyPressEvent">QWidget::keyPressEvent</a>() and +<a href="qwidget.html#keyReleaseEvent">QWidget::keyReleaseEvent</a>() receive key events. +<p> <p>See also <a href="qfocusevent.html">QFocusEvent</a>, <a href="qwidget.html#grabKeyboard">QWidget::grabKeyboard</a>(), and <a href="events.html">Event Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="QKeyEvent"></a>QKeyEvent::QKeyEvent ( <a href="qevent.html#Type-enum">Type</a> type, int key, int ascii, int state, const <a href="qstring.html">QString</a> & text = QString::null, bool autorep = FALSE, ushort count = 1 ) +</h3> + +<p> Constructs a key event object. +<p> The <em>type</em> parameter must be <a href="qevent.html#Type-enum">QEvent::KeyPress</a> or <a href="qevent.html#Type-enum">QEvent::KeyRelease</a>.
