How to get type of TValue?

Question

I need to get the type of a TValue.

TControl *control = MyForm->Controls[1337];
TRttiContext ctx;
TRttiType *type = ctx.GetType(control->ClassInfo());
TRttiProperty *property = type->GetProperty("Text"); // or "Caption", etc.
TValue result = property->GetValue(control);

if (result.IsType(tkUString)) {  
    std::cout << "String!" << std::endl;
else 
    std::cout << "NOT String!" << std::endl;

I get the following error:

[bcc64 Error] Unit1.cpp(142): no matching member function for call to 'IsType'
System.Rtti.hpp(323): candidate function not viable: no known conversion from 'System::TTypeKind' to 'System::Typinfo::PTypeInfo' (aka 'System::Typinfo::TTypeInfo *') for 1st argument

Looking at the documentation IsType() takes a PTypeInfo argument (which tkUString is not).

But there is no C++ documentation on PTypeInfo, only Delphi.

Must I include a Delphi unit in my project to use TValue.IsType()?

Answer 1

I was using the wrong method.

This is wrong:

if (result.IsType(tkUString)) {  

This is correct:

if (result.Kind == tkUString) {
