SetInteger

Provides simplified access to the functions of API MQL5 ObjectSetInteger() to change integer properties (of type bool, char, uchar, short, ushort, int, uint, long, ulong, datetime, color types) of a graphical object bound to class instance. There are two versions of the function call:

Setting a property value that does not require a modifier

bool  SetInteger(
   ENUM_OBJECT_PROPERTY_INTEGER   prop_id,     // integer property ID
   long                           value        // value
   )

Parameters

prop_id

[in]  ID of a graphical object integer property.

value

[in]  New value of a changed integer property.

Setting a property value indicating the modifier

bool  SetInteger(
   ENUM_OBJECT_PROPERTY_INTEGER   prop_id,      // integer property ID
   int                            modifier,     // modifier 
   long                           value         // value
   )

Parameters

prop_id

[in]  ID of a graphical object integer property.

modifier

[in]  Modifier (index) of an integer property.

value

[in]  New value of an integer property.

Return Value

true - success, false - cannot change the integer property.

Example:

//--- example for CChartObject::SetInteger  
#include <ChartObjects\ChartObject.mqh>  
//---  
void OnStart()  
  {  
   CChartObject object;  
   //--- set new color of chart object   
   if(!object.SetInteger(OBJPROP_COLOR,clrRed))  
     {  
      printf("Set integer property error %d",GetLastError());  
      return;  
     }  
   for(int i=0;i<object.LevelsCount();i++)  
     {  
      //--- set levels width  
      if(!object.SetInteger(OBJPROP_LEVELWIDTH,i,i))  
        {  
         printf("Set integer property error %d",GetLastError());  
         return;  
        }  
     }  
  }
