Constructor & Destructor Documentation

◆ QTouchEvent()

QTouchEvent::QTouchEvent ( QEvent::Type  eventType,
const QPointingDevice *  device = nullptr,
Qt::KeyboardModifiers  modifiers = Qt::NoModifier,
const QList< QEventPoint > &  touchPoints = {} 
)
explicit
Deprecated:
[6.2] Use another constructor.

Constructs a QTouchEvent with the given eventType, device, touchPoints, and current keyboard modifiers at the time of the event.

Deprecated:
[6.0] Use another constructor.

Constructs a QTouchEvent with the given eventType, device, and touchPoints. The touchPointStates and modifiers are the current touch point states and keyboard modifiers at the time of the event.

Here is the call graph for this function:

◆ ~QTouchEvent()

QTouchEvent::~QTouchEvent ( )

Destroys the QTouchEvent.

Member Function Documentation

◆ clone()

QTouchEvent* QTouchEvent::clone ( ) const
inlineoverridevirtual

Creates and returns an identical copy of this event.

Since
6.0

Reimplemented from QPointerEvent.

Definition at line 1039 of file qevent.h.

◆ isBeginEvent()

bool QTouchEvent::isBeginEvent ( ) const
overridevirtual

Returns true if this event includes at least one newly-pressed touchpoint.

Reimplemented from QPointerEvent.

Definition at line 4607 of file qevent.cpp.

◆ isEndEvent()

bool QTouchEvent::isEndEvent ( ) const
overridevirtual

Returns true if this event includes at least one newly-released touchpoint.

Reimplemented from QPointerEvent.

Definition at line 4625 of file qevent.cpp.

◆ isUpdateEvent()

bool QTouchEvent::isUpdateEvent ( ) const
overridevirtual

Returns true if this event does not include newly-pressed or newly-released touchpoints.

Reimplemented from QPointerEvent.

Definition at line 4616 of file qevent.cpp.

◆ target()

QObject * QTouchEvent::target ( ) const
inline

Returns the target object within the window on which the event occurred. This is typically a QWidget or a QQuickItem. May be 0 when no specific target is available.

Definition at line 1041 of file qevent.h.

Here is the caller graph for this function:

◆ touchPointStates()

QEventPoint::States QTouchEvent::touchPointStates ( ) const
inline

Returns a bitwise OR of all the touch point states for this event.
