Qt如何向系統發送鍵盤和鼠標事件？

向系統發送鍵盤事件：
void QWSServer::sendKeyEvent ( int unicode, int keycode, Qt::KeyboardModifiers modifiers, bool isPress, bool autoRepeat ) [static]
向系統發送鼠標事件：
QMouseEvent *mEvnPress;
  QMouseEvent *mEvnRelease;
  mEvnPress = new QMouseEvent(QEvent::MouseButtonPress, pos, Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);
  QApplication::sendEvent(QWidget::focusWidget(),mEvnPress);
  mEvnRelease = new QMouseEvent(QEvent::MouseButtonRelease, pos, Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);

  QApplication::sendEvent(QWidget::focusWidget(),mEvnRelease);
