c++ - Iterate Over Struct; Easily Display Struct Fields And Values In a RichEdit Box

Question

Is there an easier way to display the struct fields and their corresponding values in RichEdit control?

This is what I am doing now:

AnsiString s;

s = IntToStr(wfc.fontColor);
RichEdit1->Lines->Append(s);

etc...

Is there an easier way than having to individually call each one? I want to read a binary file and then display the corresponding structure in a RichEdit control for a small utility I am building and have found no other way. I know how to read binary files and read the values into the struct already.

BOOST_FUSION_ADAPT_STRUCT seems to fit well here. For example:

// Your existing struct
struct Foo
{
    int i;
    bool j;
    char k[100];
};

// Generate an adapter allowing to view "Foo" as a Boost.Fusion sequence
BOOST_FUSION_ADAPT_STRUCT(
    Foo,
    (int, i)
    (bool, j)
    (char, k[100])
)

// The action we will call on each member of Foo
struct AppendToTextBox
{
    AppendToTextBox(RichEditControl& Ctrl) : m_Ctrl(Ctrl){}

    template<typename T>
    void operator()(T& t)const
    {

        m_Ctrl.Lines.Append(boost::lexical_cast<std::string>(t));
    }

    RichEditControl& m_Ctrl;

};

// Usage:
void FillTextBox(Foo& F, RichEditControl& Ctrl)
{
    boost::fusion::for_each(F, AppendToTextBox(Ctrl));
}
