Hi ,

I am trying to Generate a mouse button click event in mql ..


  if(!EventChartCustom(0, CHARTEVENT_CUSTOM+CHARTEVENT_OBJECT_CLICK,0,0,,btnName))
   Print('Error ',GetLastError());

.. but no luck.

Would appreciate some ideas .. thanks a lot

You can NOT add two parameters, like you did with
 CHARTEVENT_CUSTOM + CHARTEVENT_OBJECT_CLICK
This is error.
They have to be separated in two EventChartCustom()

in declaracion:

string btn_close_SELLS='btn_close_SELLS';

then in Void Ontick (void)

Create_Button(btn_close_SELLS,'CLOSE SELLS',85,18,110,420,LightSlateGray,White);

copy the following code at the end of your expert

void Create_Button(string but_name,string label,int xsize,int ysize,int xdist,int ydist,int bcolor,int fcolor)
  {
   if(ObjectFind(0,but_name)<0)
     {
      if(!ObjectCreate(0,but_name,OBJ_BUTTON,0,0,0))
        {
         Print(__FUNCTION__,
               ': failed to create the button! Error code = ',GetLastError());
         return;
        }
      ObjectSetString(0,but_name,OBJPROP_TEXT,label);
      ObjectSetInteger(0,but_name,OBJPROP_XSIZE,xsize);
      ObjectSetInteger(0,but_name,OBJPROP_YSIZE,ysize);
      ObjectSetInteger(0,but_name,OBJPROP_CORNER,1);
      ObjectSetInteger(0,but_name,OBJPROP_XDISTANCE,xdist);
      ObjectSetInteger(0,but_name,OBJPROP_YDISTANCE,ydist);
      ObjectSetInteger(0,but_name,OBJPROP_BGCOLOR,bcolor);
      ObjectSetInteger(0,but_name,OBJPROP_COLOR,fcolor);
      ObjectSetInteger(0,but_name,OBJPROP_FONTSIZE,9);
      ObjectSetInteger(0,but_name,OBJPROP_HIDDEN,true);
      //ObjectSetInteger(0,but_name,OBJPROP_BORDER_COLOR,ChartGetInteger(0,CHART_COLOR_FOREGROUND));
      ObjectSetInteger(0,but_name,OBJPROP_BORDER_TYPE,BORDER_RAISED);
      ChartRedraw();
     }
  }

and this also at the end of you expert

void OnChartEvent(const int id,const long &lparam,const double &dparam,const string &sparam)
  {
   if(id==CHARTEVENT_OBJECT_CLICK)
     {
      if(sparam==btn_close_SELLS)
        {
         ObjectSetString(0,btn_close_SELLS,OBJPROP_TEXT,'Close SELLS');
         {CloseAllShorts();}
         ObjectSetInteger(0,btn_close_SELLS,OBJPROP_STATE,0);
         ObjectSetString(0,btn_close_SELLS,OBJPROP_TEXT,'Close SELLS');
         ObjectDelete(btn_close_SELLS);
        }
     }
  }

the function CloseAllShorts () you have to create youself or something else you want to do with that button



Good luck

write a c based dll.

if you cant get it done by writing a c based dll, it cant be done.

if you dont have a c compiler, you could download devcpp.
