Public Member Functions

 QGraphicsSceneResizeEvent ()
 Constructs a QGraphicsSceneResizeEvent.
 
 ~QGraphicsSceneResizeEvent ()
 Destroys the QGraphicsSceneResizeEvent.
 
QSizeF oldSize () const
 Returns the old size (i.e., the size immediately before the widget was resized).
 
void setOldSize (const QSizeF &size)
 
QSizeF newSize () const
 Returns the new size (i.e., the current size).
 
void setNewSize (const QSizeF &size)
 
- Public Member Functions inherited from QGraphicsSceneEvent
 QGraphicsSceneEvent (Type type)
 
 ~QGraphicsSceneEvent ()
 Destroys the event.
 
QWidget * widget () const
 Returns the widget where the event originated, or \nullptr if the event originates from another application.
 
void setWidget (QWidget *widget)
 
quint64 timestamp () const
 
void setTimestamp (quint64 ts)
 
- Public Member Functions inherited from QEvent
 QEvent (Type type)
 Constructs an event object of type type.
 
virtual ~QEvent ()
 Destroys the event.
 
Type type () const
 Returns the event type.
 
bool spontaneous () const
 Returns true if the event originated outside the application (a system event); otherwise returns false.
 
virtual void setAccepted (bool accepted)
 
bool isAccepted () const
 
void accept ()
 Sets the accept flag of the event object, the equivalent of calling setAccepted(true).
 
void ignore ()
 Clears the accept flag parameter of the event object, the equivalent of calling setAccepted(false).
 
bool isInputEvent () const noexcept
 
bool isPointerEvent () const noexcept
 
bool isSinglePointEvent () const noexcept
 
virtual QEvent * clone () const
 Creates and returns an identical copy of this event.

Detailed Description

The QGraphicsSceneResizeEvent class provides events for widget resizing in the graphics view framework.

Since
4.4

\inmodule QtWidgets

A QGraphicsWidget sends itself a QGraphicsSceneResizeEvent immediately when its geometry changes.

It's similar to QResizeEvent, but its sizes, oldSize() and newSize(), use QSizeF instead of QSize.
