hi..

yaa i had read it and used it with the same concept but the problem was there... i would show u those few lines where i had done so...
Qt Code: 
  1. Q3CanvasItemList l = m_pCanvas->collisions(item);
  2.      selCanItem = l;
  3.      for (Q3CanvasItemList::Iterator it= selCanItem.begin(); it!= selCanItem.end(); ++it) 
  4.      {
  5.        if ( (*it)->rtti() == 7 )
  6.        {
  7.             for(i=0;i<42;i++)
  8.             {
  9.                 if((i<GlobalOutYLineList.size()) && ((*it)->collidesWith(GlobalOutYLineList.at(i))))
  10.                 {
  11.                      QMessageBox::information(this, tr("CGUITileType"),tr("GlobalOutYLineList Line %1 Mouse Event Handled ").arg(i));  
  12.                      m_pCLineGlobalOutY[i]->setPen(QPen(Qt::red));
  13.                      startPoint = m_pCLineGlobalOutY[i]->startPoint();
  14.                      endPoint = m_pCLineGlobalOutY[i]->endPoint();
  15.                      m_pCLineGlobalOutY[i]->setPoints(startPoint.x(),startPoint.y(),endPoint.x(),endPoint.y());                         
  16.                      m_pCLineGlobalOutY[i]->show();
  17.                      break;
  18.                 }
  19.                 else if((i<V1_DirectInputLineList.size())&& ((*it)->collidesWith(V1_DirectInputLineList.at(i))))
  20.                 {
  21.                      QMessageBox::information(this, tr("CGUITileType"),tr("V1_DirectInputLineList Line %1 Mouse Event Handled ").arg(i));  
  22.                      m_pV1_CLineDirectInput[i]->setPen(QPen(Qt::red));
  23.                      startPoint = m_pV1_CLineDirectInput[i]->startPoint();
  24.                      endPoint = m_pV1_CLineDirectInput[i]->endPoint();
  25.                      m_pV1_CLineDirectInput[i]->setPoints(startPoint.x(),startPoint.y(),endPoint.x(),endPoint.y());                         
  26.                      m_pV1_CLineDirectInput[i]->show();
  27.                      break;
  28.                  }

Now the problem is no matter which canvas item i click, it enters the first 'if' and highlights the 0th item...
