Sending event from child widget

[kwisp]

why you are writing this order:

QWidget::mouseDoubleClickEvent(event);
    QMouseEvent translatedEvent(event->type(),
                               mapTo(parentWidget(), event->pos()),
                               event->button(),
                               event->buttons(),
                               event->modifiers());
    qApp->sendEvent(parentWidget(), &translatedEvent);

QWidget::mouseDoubleClickEvent(event);
    QMouseEvent translatedEvent(event->type(),
                               mapTo(parentWidget(), event->pos()),
                               event->button(),
                               event->buttons(),
                               event->modifiers());
    qApp->sendEvent(parentWidget(), &translatedEvent);

To copy to clipboard, switch view to plain text mode 

why not

QMouseEvent translatedEvent(event->type(),
                               mapTo(parentWidget(), event->pos()),
                               event->button(),
                               event->buttons(),
                               event->modifiers());
    qApp->sendEvent(parentWidget(), &translatedEvent);
QWidget::mouseDoubleClickEvent(event);

QMouseEvent translatedEvent(event->type(),
                               mapTo(parentWidget(), event->pos()),
                               event->button(),
                               event->buttons(),
                               event->modifiers());
    qApp->sendEvent(parentWidget(), &translatedEvent);
QWidget::mouseDoubleClickEvent(event);

To copy to clipboard, switch view to plain text mode 

why you are calling
QWidget::mouseDoubleClickEvent(event);
at all?
