[Qt-interest] Is the code safe when I called sendEvent(...) without a stack event?

[Kermit Mei]

Dear all, 
    
Assistant told us that the event argument used by
QCoreApplication::sendEvent(QObject *, QEvent *) should be create in the
stack. Because the it can't be delete when send. Then I want to know
wheather the following code is safe:


void SubWidget::keypressEvent(QKeyEvent *event) {
    if(needToProcessInParent() == true) {
        QCoreApplication::sendEvent(parent(), QEvent *event);
        return ;
    }else {
        processInSubWidget();    
    }
}


    I haven't create the event on the stack, but it also need not be
deleted when it sent. So I consider it's safe. And when sendEvent(...)
called here, the SubWidget will not process the event.
    Isn't it?

Thanks
