To me the proper way of doing what the thread author wants is:

void XXX::mousePressEvent(QMouseEvent *e){
  if(e->buttons() & (Qt::LeftButton|Qt::RightButton))
    doSomething();
  else
    baseClass::mousePressEvent(e);
}

void XXX::mousePressEvent(QMouseEvent *e){
  if(e->buttons() & (Qt::LeftButton|Qt::RightButton))
    doSomething();
  else
    baseClass::mousePressEvent(e);
}

To copy to clipboard, switch view to plain text mode 

One might also use == instead of & depending on the effect one wants to obtain.

i tried u r code it enters if condition even if one button is clicked .but the author of post wants only when both the buttons are active.
this can be done by

if(event->buttons() == (Qt::LeftButton | Qt::RightButton))
code();

i have tested it and it works

but one question why do we use or operator and that too unary.
