 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.

Constructor & Destructor Documentation

◆ QMetaCallEvent() [1/6]

QMetaCallEvent::QMetaCallEvent ( ushort method_offset,
ushort method_relative,
QObjectPrivate::StaticMetaCallFunction callFunction,
const QObject * sender,
int signalId,
void ** args,
QSemaphore * semaphore )

Used for blocking queued connections, just passes args through without allocating any memory.

Definition at line 506 of file qobject.cpp.

◆ QMetaCallEvent() [2/6]

QMetaCallEvent::QMetaCallEvent ( QtPrivate::QSlotObjectBase * slotO,
const QObject * sender,
int signalId,
void ** args,
QSemaphore * semaphore )

Used for blocking queued connections, just passes args through without allocating any memory.

Definition at line 522 of file qobject.cpp.

◆ QMetaCallEvent() [3/6]

QMetaCallEvent::QMetaCallEvent ( QtPrivate::SlotObjUniquePtr slotO,
const QObject * sender,
int signalId,
void ** args,
QSemaphore * semaphore )

Used for blocking queued connections, just passes args through without allocating any memory.

Definition at line 539 of file qobject.cpp.

◆ QMetaCallEvent() [4/6]

QMetaCallEvent::QMetaCallEvent ( ushort method_offset,
ushort method_relative,
QObjectPrivate::StaticMetaCallFunction callFunction,
const QObject * sender,
int signalId,
int nargs )

Allocates memory for nargs; code creating an event needs to initialize the void* and int arrays by accessing args() and types(), respectively.

Definition at line 554 of file qobject.cpp.

◆ QMetaCallEvent() [5/6]

QMetaCallEvent::QMetaCallEvent ( QtPrivate::QSlotObjectBase * slotO,
const QObject * sender,
int signalId,
int nargs )

Allocates memory for nargs; code creating an event needs to initialize the void* and int arrays by accessing args() and types(), respectively.

Definition at line 571 of file qobject.cpp.

◆ QMetaCallEvent() [6/6]

QMetaCallEvent::QMetaCallEvent ( QtPrivate::SlotObjUniquePtr slotO,
const QObject * sender,
int signalId,
int nargs )

Allocates memory for nargs; code creating an event needs to initialize the void* and int arrays by accessing args() and types(), respectively.
