Detailed Description

Member Function Documentation

[since 6.0] const QInputDevice *QInputEvent::device() const

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.

This function was introduced in Qt 6.0.

See also QPointerEvent::pointingDevice().

QInputDevice::DeviceType QInputEvent::deviceType() const

Returns the type of device that generated the event.

Qt::KeyboardModifiers QInputEvent::modifiers() const

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

See also QGuiApplication::keyboardModifiers().

quint64 QInputEvent::timestamp() const

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.
