It is not sufficient to pass +the widget stack as parent to a widget which should be inserted into +the widgetstack. +<p> <a href="#visibleWidget">visibleWidget</a>() is the <em>get</em> equivalent of raiseWidget(); it +returns a pointer to the widget that is currently at the top of +the stack. +<p> QWidgetStack also provides the ability to manipulate widgets +through application-specified integer IDs. You can also translate +from widget pointers to IDs using <a href="#id">id</a>() and from IDs to widget +pointers using <a href="#widget">widget</a>(). These numeric IDs are unique (per +QWidgetStack, not globally), but QWidgetStack does not attach any +additional meaning to them. +<p> The default widget stack is frameless, but you can use the usual +<a href="qframe.html">QFrame</a> functions (such as <a href="qframe.html#setFrameStyle">setFrameStyle</a>()) to add a frame. +<p> QWidgetStack provides a signal, <a href="#aboutToShow">aboutToShow</a>(), which is emitted +just before a managed widget is shown. +<p> <p>See also <a href="qtabdialog.html">QTabDialog</a>, <a href="qtabbar.html">QTabBar</a>, <a href="qframe.html">QFrame</a>, and <a href="organizers.html">Organizers</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="QWidgetStack"></a>QWidgetStack::QWidgetStack ( <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 ) +</h3> +Constructs an empty widget stack. +<p> The <em>parent</em> and <em>name</em> arguments are passed to the <a href="qframe.html">QFrame</a> +constructor. + +<h3 class=fn><a name="QWidgetStack-2"></a>QWidgetStack::QWidgetStack ( <a href="qwidget.html">QWidget</a> * parent, const char * name, WFlags f ) +</h3> +Constructs an empty widget stack. +<p> The <em>parent</em>, <em>name</em> and <em>f</em> arguments are passed to the <a href="qframe.html">QFrame</a> +constructor. + +<h3 class=fn><a name="~QWidgetStack"></a>QWidgetStack::~QWidgetStack () +</h3> +Destroys the object and frees any allocated resources. + +<h3 class=fn>void <a name="aboutToShow"></a>QWidgetStack::aboutToShow ( int )<tt> [signal]</tt> +</h3> + +<p> This signal is emitted just before a managed widget is shown if +that managed widget has an ID != -1.
