Detailed Description

The QStackedLayout class provides a stack of widgets where only one widget is visible at a time.

QStackedLayout can be used to create a user interface similar to the one provided by QTabWidget. There is also a convenience QStackedWidget class built on top of QStackedLayout.

A QStackedLayout can be populated with a number of child widgets ("pages"). For example:

QWidget *firstPageWidget = new QWidget;

QWidget *secondPageWidget = new QWidget;

QWidget *thirdPageWidget = new QWidget;

QStackedLayout *stackedLayout = new QStackedLayout;

stackedLayout->addWidget(firstPageWidget);

stackedLayout->addWidget(secondPageWidget);

stackedLayout->addWidget(thirdPageWidget);

QVBoxLayout *mainLayout = new QVBoxLayout;

mainLayout->addLayout(stackedLayout);

setLayout(mainLayout);

QStackedLayout 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 QStackedLayout's pages. For example:

QComboBox *pageComboBox = new QComboBox;

pageComboBox->addItem(tr("Page 1"));

pageComboBox->addItem(tr("Page 2"));

pageComboBox->addItem(tr("Page 3"));

connect(pageComboBox, SIGNAL(activated(int)),

stackedLayout, SLOT(setCurrentIndex(int)));

When populating a layout, 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 the widget at the given index from the layout. The number of widgets contained in the layout, 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 layout changes or a widget is removed from the layout, the currentChanged() and widgetRemoved() signals are emitted respectively.

Member Enumeration Documentation

enum QtGui.QStackedLayout.StackingMode

This enum specifies how the layout handles its child widgets regarding their visibility.

This enum was introduced or modified in Qt 4.4.

Enumerator:

StackAll	All widgets are visible. The current widget is merely raised.
StackOne	Only the current widget is visible. This is the default.

Constructor & Destructor Documentation

QtGui.QStackedLayout.QStackedLayout ( System.Type dummy )

protected

QtGui.QStackedLayout.QStackedLayout ( )

Constructs a QStackedLayout with no parent.

This QStackedLayout must be installed on a widget later on to become effective.

See also addWidget() and insertWidget().

QtGui.QStackedLayout.QStackedLayout ( QWidget parent )

Constructs a new QStackedLayout with the given parent.

This layout will install itself on the parent widget and manage the geometry of its children.

QtGui.QStackedLayout.QStackedLayout ( QLayout parentLayout )

Constructs a new QStackedLayout and inserts it into the given parentLayout.

Member Function Documentation

override void QtGui.QStackedLayout.AddItem ( IQLayoutItem item )

virtual

Reimplemented from QLayout::addItem().

Implements QtGui.QLayout.

new int QtGui.QStackedLayout.AddWidget ( QWidget w )

Adds the given widget to the end of this layout and returns the index position of the widget.

If the QStackedLayout is empty before this function is called, the given widget becomes the current widget.

See also insertWidget(), removeWidget(), and setCurrentWidget().

override int QtGui.QStackedLayout.Count ( )

virtual

Must be implemented in subclasses to return the number of items in the layout.

Property Documentation

Slot<System.Int32> QtGui.QStackedLayout.CurrentChanged

addremove

This signal is emitted whenever the current widget in the layout changes. The index specifies 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 QStackedLayout)

See also currentWidget() and setCurrentWidget().

new int QtGui.QStackedLayout.CurrentIndex

getset

This property holds the index position of the widget that is visible.

The current index is -1 if there is no current widget.

new QWidget QtGui.QStackedLayout.CurrentWidget

getset

Returns the current widget, or 0 if there are no widgets in this layout.

Sets the current widget to be the specified widget. The new current widget must already be contained in this stacked layout.

new IQStackedLayoutSignals QtGui.QStackedLayout.Emit

getprotected

override QRect QtGui.QStackedLayout.Geometry

getset

Reimplemented from QLayoutItem::setGeometry().

new StackingMode QtGui.QStackedLayout.stackingMode

getset

This property determines the way visibility of child widgets are handled.

The default value is StackOne. Setting the property to StackAll allows you to make use of the layout for overlay widgets that do additional drawing on top of other widgets, for example, graphical editors.

This property was introduced in Qt 4.4.

new QMetaObject QtGui.QStackedLayout.StaticMetaObject

staticget

Slot<System.Int32> QtGui.QStackedLayout.WidgetRemoved

addremove

This signal is emitted whenever a widget is removed from the layout. The widget's index is passed as parameter.

new int QtGui.QStackedLayout.InsertWidget	(	int	index,
		QWidget	w
	)
