Type testing

[Atmapuri]

Hi!

How do I write in C++:

Is MyVar of MyType

to get a a boolean answer? I would like to test this
for TObject descendants and for other types in C++.

Thanks!

typeid(MyVar) == typeid(MyType)

Hi!

I need something else because in watches I get
error: RTTI not available for expression evaluation.

Thanks!

Use dynamic_cast, ie:

if( dynamic_cast<MyType>(MyVar) != NULL )
...

dynamic_cast only works with polymorphic types that have RTTI attached to
them.
