详细描述
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:
参见 QLayout, QSpacerItem, and QLayoutItem::widget().
成员函数
QWidgetItem::QWidgetItem(QWidget *widget)
Creates an item containing the given widget.
QWidgetItem::~QWidgetItem()
Destructor.
[override virtual] QSizePolicy::ControlTypes QWidgetItem::controlTypes() const
Reimplemented from QLayoutItem::controlTypes().
Returns the control type associated with the widget for which this size policy applies.
参见 QSizePolicy::controlType().
[override virtual] Qt::Orientations QWidgetItem::expandingDirections() const
Reimplemented from QLayoutItem::expandingDirections().
[override virtual] QRect QWidgetItem::geometry() const
Reimplemented from QLayoutItem::geometry().
参见 setGeometry().
[override virtual] bool QWidgetItem::hasHeightForWidth() const
Reimplemented from QLayoutItem::hasHeightForWidth().
[override virtual] int QWidgetItem::heightForWidth(int w) const
Reimplemented from QLayoutItem::heightForWidth().
[override virtual] bool QWidgetItem::isEmpty() const
Reimplemented from QLayoutItem::isEmpty().
Returns true if the widget is hidden; otherwise returns false.
参见 QWidget::isHidden().
[override virtual] QSize QWidgetItem::maximumSize() const
Reimplemented from QLayoutItem::maximumSize().
[override virtual] QSize QWidgetItem::minimumSize() const
Reimplemented from QLayoutItem::minimumSize().
[override virtual] void QWidgetItem::setGeometry(const QRect &rect)
Reimplemented from QLayoutItem::setGeometry().
参见 geometry().
[override virtual] QSize QWidgetItem::sizeHint() const
Reimplemented from QLayoutItem::sizeHint().
[override virtual] QWidget *QWidgetItem::widget()
Reimplemented from QLayoutItem::widget().
Returns the widget managed by this item.
