详细描述

成员函数文档编制

`[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 .

该函数在 Qt 6.0 引入。

QInputDevice::DeviceType QInputEvent:: deviceType () const

返回生成事件的设备类型。

Qt::KeyboardModifiers QInputEvent:: modifiers () const

返回事件发生前立即存在的键盘修饰符标志。

quint64 QInputEvent:: timestamp () const

返回此事件的窗口系统时间戳。通常以毫秒为单位，从某些任意时间点 (譬如：系统启动时间) 起。
