Indicates that the type information member is the default member for display in the user interface.

[uidefault]

The uidefault C++ attribute has the same functionality as the uidefault MIDL attribute.

The following code shows a sample of uidefault:

// cpp_attr_ref_uidefault.cpp
// compile with: /LD
#include "unknwn.h"
[module(name="MyLib")];

[object, uuid("9E66A290-4365-11D2-A997-00C04FA37DDB")]
__interface ICustom{
   HRESULT Custom([in] long l, [out, retval] long *pLong);
   [uidefault]HRESULT id0([in] long l);
   [uidefault]HRESULT id1([in] long l);

   [uidefault, propget] HRESULT get_y(int *y);
   [uidefault, propput] HRESULT put_y(int y);
};
