Member Function Documentation

◆ clone()

QInputEvent* QInputEvent::clone ( ) const
inlineoverridevirtual

Creates and returns an identical copy of this event.

Since
6.0

Reimplemented from QEvent.

Reimplemented in QTouchEvent, QContextMenuEvent, QKeyEvent, QHoverEvent, QMouseEvent, QEnterEvent, QSinglePointEvent, and QPointerEvent.

Definition at line 81 of file qevent.h.

◆ device()

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()

Definition at line 83 of file qevent.h.

Here is the caller graph for this function:

◆ deviceType()

QInputDevice::DeviceType QInputEvent::deviceType ( ) const
inline

Returns the type of device that generated the event.

Definition at line 84 of file qevent.h.

◆ modifiers()

Qt::KeyboardModifiers QInputEvent::modifiers ( ) const
inline

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

See also
QGuiApplication::keyboardModifiers()

Definition at line 85 of file qevent.h.

Here is the caller graph for this function:

◆ setModifiers()

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

Definition at line 86 of file qevent.h.

◆ setTimestamp()

void QInputEvent::setTimestamp ( quint64  timestamp)
inlinevirtual

Reimplemented in QPointerEvent.

Definition at line 88 of file qevent.h.

Here is the caller graph for this function:

◆ 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.
