## Detailed Description

Normally, you don't need to use this class directly. Qt's built-in layout managers provide the following functions for manipulating widgets in layouts:

Class | Functions
--- | ---
QBoxLayout | addWidget(), insertWidget(), setStretchFactor()
QGridLayout | addWidget()
QStackedLayout | addWidget(), insertWidget(), currentWidget(), setCurrentWidget(), widget()

See also QLayout, QSpacerItem, and QLayoutItem::widget().
