Simulate mouse click inside QTextEdit in Qt?

[vk41286]

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();
}

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();
}

To copy to clipboard, switch view to plain text mode 

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.

Are you sure this is really what you want? Maybe instead you want the widget to gain focus or maybe you want to position the text cursor in a given position? Which is it then?
