In which line does the compiler give an error?

[Nauris Zukas]

Good afternoon!

Made a line that I want to move freely. At the moment you have to click on the line and only then you can move it. How can I make it possible to move the line without double clicking?

double startL;
//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
//---
startL=Bid;

SetHLine(clrAqua, "", startL, STYLE_SOLID, 5);    
//---
   return(INIT_SUCCEEDED);
  }
//+------------------------------------------------------------------+
//| Expert deinitialization function                                 |

void OnDeinit(const int reason)

void OnTick()

  }

color array_color[5]={clrRed,clrAliceBlue,clrAqua,clrRoyalBlue,clrCrimson};
void OnChartEvent(const int    id,
                  const long   &lparam,
                  const double &dparam,
                  const string &sparam)
  {
   if(id==CHARTEVENT_OBJECT_DRAG)
     {
      Print("object name: ",sparam);
      ObjectSetInteger(0,sparam,OBJPROP_COLOR,array_color[rand()%5]);
     }
  }
    

void SetHLine(color cl, string nm="", double p1=0, int st=0, int wd=1) {
  if (nm=="") nm=DoubleToStr(Time[0], 0);
  if (p1<=0) p1=Bid;
  if (ObjectFind(nm)<0) ObjectCreate(nm, OBJ_HLINE, 0, 0,0);
  ObjectSet(nm, OBJPROP_PRICE1, p1);
  ObjectSet(nm, OBJPROP_COLOR , cl);
  ObjectSet(nm, OBJPROP_STYLE , st);
  ObjectSet(nm, OBJPROP_WIDTH , wd);

ObjectSetInteger(0,nm,OBJPROP_SELECTED,true);

Actually, you wrote a very old design

[Nauris Zukas]

Vitaly Muzichenko:

ObjectSetInteger(0,nm,OBJPROP_SELECTED,true);

Thank you, but something didn't work. I put it this way, maybe something is wrong?

   if(id==CHARTEVENT_OBJECT_DRAG)
     {
      Print("object name: ",sparam);
      ObjectSetInteger(0,sparam,OBJPROP_SELECTED,true);
      ObjectSetInteger(0,sparam,OBJPROP_COLOR,array_color[rand()%5],true);     
     }

Vitaly Muzichenko:
Actually, you have written a very old construction.

I searched through the forum, I've seen constructions with classes, but I'm not good at classes, so I wanted to start with the simplest one (in terms of appearance).

Nauris Zukas:

There should be a pair with OBJPROP_SELECTABLE

   if(id==CHARTEVENT_OBJECT_DRAG)
     {
      Print("object name: ",sparam);
      ObjectSetInteger(0,sparam,OBJPROP_SELECTABLE,true);
      ObjectSetInteger(0,sparam,OBJPROP_SELECTED,true);
      ObjectSetInteger(0,sparam,OBJPROP_COLOR,array_color[rand()%5],true);     
     }

Alexey Viktorov:

I don't know, something is not working. It only moves after a double click and the line goes black.

[Alexey Viktorov]

Nauris Zukas:

I don't know, something doesn't work. It only moves after a double click and the line goes black.

Well, then add another before these two lines.

ObjectSetInteger(0, sparam, OBJPROP_HIDDEN, false);

[Nauris Zukas]

Alexey Viktorov:

Well, then add another line in front of those two lines.

Didn't work, maybe there 's a mistake in the code?

I pasted it into MetaEditor, tweaked it a little - no errors
