Why QCursor setPos() dosen't work here?

[high_flyer]

wysotas question is well in place - however, your program is not moving the cursor:

if (key == Key_Up)
{
   posTmp=pCursor->pos()+posUp;
   pCursor->setPos(0,0); //<<<<<-------you always set position 0,0
   cout<<pCursor->pos().rx()<<" "<<pCursor->pos().ry()<<endl;
}

if (key == Key_Up)
{
   posTmp=pCursor->pos()+posUp;
   pCursor->setPos(0,0); //<<<<<-------you always set position 0,0
   cout<<pCursor->pos().rx()<<" "<<pCursor->pos().ry()<<endl;
}
