80 \brief The QStackedLayout class provides a stack of widgets where-
81 only one widget is visible at a time.-
82-
83 \ingroup geomanagement-
84 \inmodule QtWidgets-
85-
86 QStackedLayout can be used to create a user interface similar to-
87 the one provided by QTabWidget. There is also a convenience-
88 QStackedWidget class built on top of QStackedLayout.-
89-
90 A QStackedLayout can be populated with a number of child widgets-
91 ("pages"). For example:-
92-
93 \snippet qstackedlayout/main.cpp 0-
94 \codeline-
95 \snippet qstackedlayout/main.cpp 2-
96 \snippet qstackedlayout/main.cpp 3-
97-
98 QStackedLayout provides no intrinsic means for the user to switch-
99 page. This is typically done through a QComboBox or a QListWidget-
100 that stores the titles of the QStackedLayout's pages. For-
101 example:-
102-
103 \snippet qstackedlayout/main.cpp 1-
104-
105 When populating a layout, the widgets are added to an internal-
106 list. The indexOf() function returns the index of a widget in that-
107 list. The widgets can either be added to the end of the list using-
108 the addWidget() function, or inserted at a given index using the-
109 insertWidget() function. The removeWidget() function removes the-
110 widget at the given index from the layout. The number of widgets-
111 contained in the layout, can be obtained using the count()-
112 function.-
113-
114 The widget() function returns the widget at a given index-
115 position. The index of the widget that is shown on screen is given-
116 by currentIndex() and can be changed using setCurrentIndex(). In a-
117 similar manner, the currently shown widget can be retrieved using-
118 the currentWidget() function, and altered using the-
119 setCurrentWidget() function.-
120-
121 Whenever the current widget in the layout changes or a widget is-
122 removed from the layout, the currentChanged() and widgetRemoved()-
123 signals are emitted respectively.-

132 changes. The \a index specifies the index of the new current-
133 widget, or -1 if there isn't a new one (for example, if there-
