Hello, is it interesting to know if, with some variable mySpace, as well as a base class designer, it is possible to set a value from enum'a? The idea is to get rid of the parameter in the foo function.

namespace mySpace{
   enum myEnum {val1=0, val2, val3, fin}; 
      const char *setVal(int par){
      static const char *valNames[fin]={"this val1","this val2","this val3"}; 
        if(par>=0 && par <fin)return valNames[fin];
        return "error"; 
     }
}
class Parent {
    public:
      virtual void foo(int par)=0;     
};
class Child : public Parent{
    public:
      void foo(int par){
         char name[64];
         sprintf(name, "%s", mySpace::setVal(par));
      }
};

For example, create a field for this parameter and initiate it when setting up the facility (transfer to the designer):

#define NAME_LENGTH 64
namespace mySpace

{

enum myEnum {

val1=0,

val2,

val3,

fin

};
const char* setVal( int par )
{
    static const char* valNames[ fin ] = {
        "this val1", "this val2", "this val3"
    }; 

    if ( par >= 0 && par < fin )
        return valNames[ fin ];

    return "error"; 
}

}
class Parent

{

public:

virtual void foo()=0;

private:

int _par;

};
class Child : public Parent

{

public:

Child( int parameter )

{

_par = parameter;

}

void foo()

{

char name[ NAME_LENGTH ];

sprintf( name, "%s", mySpace::setVal( _par ) );

}

};
