Member Function Documentation

device()

const QInputDevice * QInputEvent::device ( ) const

inline

Since

6.0

Returns the source device that generated the original event.

In case of a synthesized event, for example a mouse event that was generated from a touch event, device() continues to return the touchscreen device, so that you can tell that it did not come from an actual mouse. Thus {mouseEvent.source()->type() != QInputDevice::DeviceType::Mouse} is one possible replacement for the Qt 5 expression {mouseEvent.source() == Qt::MouseEventSynthesizedByQt}.

QPointerEvent::pointingDevice()

deviceType()

QInputDevice::DeviceType QInputEvent::deviceType ( ) const

inline

Returns the type of device that generated the event.

Definition at line 55 of file qevent.h.

modifiers()

Qt::KeyboardModifiers QInputEvent::modifiers ( ) const

inline

Returns the keyboard modifier flags that existed immediately before the event occurred.

QGuiApplication::keyboardModifiers()

Definition at line 56 of file qevent.h.

setModifiers()

void QInputEvent::setModifiers ( Qt::KeyboardModifiers modifiers )

inline

Sets the keyboard modifiers flags for this event.

Definition at line 57 of file qevent.h.

setTimestamp()

virtual void QInputEvent::setTimestamp ( quint64 atimestamp )

inlinevirtual

Sets the timestamp for this event.

Reimplemented in QPointerEvent.

Definition at line 59 of file qevent.h.

timestamp()

quint64 QInputEvent::timestamp ( ) const

inline

Returns the window system's timestamp for this event.

It will normally be in milliseconds since some arbitrary point in time, such as the time when the system was started.
