[Qt-interest] Qt C++ with some C++.NET calls

[Sylvain Pointeau]

Hello again,

it is working!
that's purely great :-D

in a .h

#include <QString>


struct TestImpl;


class Test {

private:

TestImpl *d;


public:

Test();

~Test();


 void setName( QString x );

int myint();

};


in the .cpp


#include <vcclr.h>

#include "guid.hpp"


using namespace System;


struct TestImpl {

gcroot<String^> name;

};


Test::Test() {

d = new TestImpl;

}


Test::~Test() {

delete d;

}


void Test::setName( QString x ) {

d->name = gcnew String((const wchar_t*)x.utf16());

}


int Test::myint() {

return d->name->GetHashCode();

}


I set the compiler option to use the CLR for this .cpp file.
and I can use my unmanaged class in my Qt native application,
and it uses the .NET behind the scene.

great, really great!!

Please don't hesitate if you have any comments...

Best regards,
Sylvain
