如何在 Qt 中模拟适用于 Linux 和 Windows 的所有鼠标和键盘事件？

Question

Problem: I have a device that send to me some commands (eg: 1,2,3,...), i want simulate mouse and keyboard events according to received commands in Both Linux OS and Windows OS.

I worked with bool QCoreApplication::postEvent(QObject *receiver, QEvent *event, int priority = Qt::NormalEventPriority) but i don't know what receiver pass to it and i has problem with MouseMove action with it.

I found this help that works good in linux OS, but i have problem with this help approach in Windows OS. Is there any approach that works in both OS?

Thanks for your attention.

You can set mouse position by :

QCursor::setPos(QPoint(10,10));

Also mouse click simulation could be done by :

QMouseEvent * event1 = new QMouseEvent ((QEvent::MouseButtonPress), QPoint(10,10),
    Qt::LeftButton,
    Qt::LeftButton,
    Qt::NoModifier   );

qApp->postEvent((QObject*)myWidget,(QEvent *)event1);

QMouseEvent * event2 = new QMouseEvent ((QEvent::MouseButtonRelease), QPoint(10,10),
    Qt::LeftButton,
    Qt::LeftButton,
    Qt::NoModifier   );

qApp->postEvent((QObject*)myWidget,(QEvent *)event2);

Sending a key event to a widget is like :

QKeyEvent *event = new QKeyEvent ( QEvent::KeyPress, Qt::Key_Enter, Qt::NoModifier);
QCoreApplication::postEvent (myWidget, event);
