Simulate mouse click inside QTextEdit in Qt?

Question

I am trying to simulate a mouse click inside a QTextEdit in Qt as my application does not have any mouse or keyboard. This is an Embedded hardware board.

int main(int argc, char *argv[])
{

        QApplication a(argc, argv);
        MainWindow w;
        w.setWindowFlags(Qt::Window | Qt::FramelessWindowHint);
        w.setStyleSheet("background-color: Black;");
        w.startcomthread();
        w.show();


        QTextEdit *txt = new QTextEdit();
        txt->setWindowFlags(Qt::Window | Qt::FramelessWindowHint);
        txt->setFocus();
        txt->setStyleSheet("background-color: rgb(255, 255, 255,200);");
        txt->setGeometry(10,20,100,30);
        txt->setText("Text 1");

       QCursor::setPos((txt->pos()+=QPoint(10,10)));                                                                                                                  
       QMouseEvent * event1 = new QMouseEvent ((QEvent::MouseButtonPress), QPoint(10,10),
        Qt::LeftButton,
        Qt::LeftButton,
        Qt::NoModifier);

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

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

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


        txt->show();

        return a.exec();
}

When I run the application, I just see a Cursor on my textedit box.I want the cursor to be clicked / at-least cursor should be blinking inside textedit widget.

Thank you.

Moving mouse pointer is not necessary (though you know why you need that) but for setting the cursor inside text edit:

editWidget->activateWindow(); // some cases require
QFocusEvent* eventFocus = new QFocusEvent(QEvent::FocusIn);
qApp->postEvent(editWidget, (QEvent*)eventFocus);

And your editWidget is 'txt'.
