QStackedWidget provides no intrinsic means for the user to switch page. This is typically done through a QComboBox or a QListWidget that stores the titles of the QStackedWidget ‘s pages. For example:
pageComboBox = QComboBox()
pageComboBox.addItem(tr("Page 1"))
pageComboBox.addItem(tr("Page 2"))
pageComboBox.addItem(tr("Page 3"))
pageComboBox.activated.connect(
        stackedWidget.setCurrentIndex)
When populating a stacked widget, the widgets are added to an internal list. The indexOf() function returns the index of a widget in that list. The widgets can either be added to the end of the list using the addWidget() function, or inserted at a given index using the insertWidget() function. The removeWidget() function removes a widget from the stacked widget. The number of widgets contained in the stacked widget can be obtained using the count() function.
The widget() function returns the widget at a given index position. The index of the widget that is shown on screen is given by currentIndex() and can be changed using setCurrentIndex() . In a similar manner, the currently shown widget can be retrieved using the currentWidget() function, and altered using the setCurrentWidget() function.
Whenever the current widget in the stacked widget changes or a widget is removed from the stacked widget, the currentChanged() and widgetRemoved() signals are emitted respectively.

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.
property countᅟ: int#
This property holds the number of widgets contained by this stacked widget.
By default, this property contains a value of 0.
See also
currentIndex()  widget()
Access functions:

count()
This property holds the index position of the widget that is visible.
The current index is -1 if there is no current widget.
By default, this property contains a value of -1 because the stack is initially empty.
See also
currentWidget()  indexOf()
Access functions:

currentIndex()
setCurrentIndex()
Signal currentChanged()
Appends the given widget to the QStackedWidget and returns the index position. Ownership of widget is passed on to the QStackedWidget .
If the QStackedWidget is empty before this function is called, widget becomes the current widget.
See also
insertWidget()  removeWidget()  setCurrentWidget()
This signal is emitted whenever the current widget changes.
The parameter holds the index of the new current widget, or -1 if there isn’t a new one (for example, if there are no widgets in the QStackedWidget ).

currentWidget()  setCurrentWidget()
Notification signal of property currentIndexᅟ .
currentIndex()#
Return type:
See also
setCurrentIndex()
Getter of property currentIndexᅟ .
currentWidget()#
Return type:
QWidget
Returns the index of the given widget, or -1 if the given widget is not a child of the QStackedWidget .
See also
currentIndex()  widget()
Inserts the given widget at the given index in the QStackedWidget . Ownership of widget is passed on to the QStackedWidget . If index is out of range, the widget is appended (in which case it is the actual index of the widget that is returned).
If the QStackedWidget was empty before this function is called, the given widget becomes the current widget.
Inserting a new widget at an index less than or equal to the current index will increment the current index, but keep the current widget.
See also
addWidget()  removeWidget()  setCurrentWidget()
Removes widget from the QStackedWidget . i.e., widget is not deleted but simply removed from the stacked layout, causing it to be hidden.
Parent object and parent widget of widget will remain the QStackedWidget . If the application wants to reuse the removed widget, then it is recommended to re-parent it.
See also
addWidget()  insertWidget()  currentWidget()
Sets the current widget to be the specified widget. The new current widget must already be contained in this stacked widget.
See also
currentWidget()  setCurrentIndex()
This signal is emitted whenever a widget is removed. The widget’s index is passed as parameter.
