Hi,

To handle the mouse click events on the buttons of the scrollbar the following code may be used.

QScrollBar* pScroll=pYourTableView->verticalScrollBar();
if(pScroll){
    connect(pScroll,SIGNAL(actionTriggered (int)),this,handleScrollAction(int)));
}
void YourClass::handleScrollAction(int action)
{
   if(action==QAbstractSlider::SliderSingleStepSub)
      qDebug() <<  "Top Button Clicked";
  else if (action==QAbstactSlider::SliderSingleStepAdd)
     qDebug() << "Bottom Button Clicked";
 
}

QScrollBar* pScroll=pYourTableView->verticalScrollBar();
if(pScroll){
    connect(pScroll,SIGNAL(actionTriggered (int)),this,handleScrollAction(int)));
}
void YourClass::handleScrollAction(int action)
{
   if(action==QAbstractSlider::SliderSingleStepSub)
      qDebug() <<  "Top Button Clicked";
  else if (action==QAbstactSlider::SliderSingleStepAdd)
     qDebug() << "Bottom Button Clicked";

}
