What will happen if re-implementing non-virtual functions?

[nifei]

for example if i re-implement

QPushButton: : setText(const QString &)

QPushButton: : setText(const QString &)

To copy to clipboard, switch view to plain text mode 

in subclass of QPushButton like this, what will happen?

void MyPushButton::setText(const QString &text)
{
   QPushButton::setText(text);
   //do sth. i would like
   {
         .....
    }
}

void MyPushButton::setText(const QString &text)
{
   QPushButton::setText(text);
   //do sth. i would like
   {
         .....
    }
}

To copy to clipboard, switch view to plain text mode
