  Subject: [ROOT] getting mouse events on ROOT


  Hi, 

          I want to make a small macro that gets the x,y coordinates 
          for a set of points on my pad when I click on them sequentially. 

          I've tried something like: 

          Float_t ptsX[3], ptsY[3]; 
          TMarker *mark[3]; 
          for (Int_t iM=0;iM<3;iM++) 
          { 
                  mark[iM] = (TMarker*)gPad->WaitPrimitive("TMarker","Marker"); 
                  ptsX[iM]  = mark[iM]->GetX(); 
                  ptsY[iM] = mark[iM]->GetY(); 
          } 

          but doesn't work. It gets the first point correctly but then proceeds and 
          sets all the other points like the first one (a printout shows that). 

          Any suggestions? 
    
          Thanks! 

  Stelios.
