Detailed Description
The QWidgetItem class is a layout item that represents a widget.
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().
