Avoiding Q_DECLARE_METATYPE

[moijhd]

Hi,

I have a standard C++ object.

class A
{
 // ...
};

class A
{
 // ...
};

To copy to clipboard, switch view to plain text mode 

I can't (and I don't want to) define it as a Qt type.

Though, I still like to put it in the model (QStandardItemModel for instance).

So far, I was able to but a raw pointer into the model with the very ugly following code :

// I have
const A &a = ; //...
 
// Writing
        item->setData(
                    qVariantFromValue(
                        reinterpret_cast<void*>(
                            const_cast<A*>(
                                &a
                                )
                            )
                        ),
                    Role
                    );
 
// Reading
        const A &a = *reinterpret_cast<A*>(
                    const_cast<const void*>(
                        item->data(Role).value<void*>()
                        )
                    );

// I have
const A &a = ; //...

// Writing
        item->setData(
                    qVariantFromValue(
                        reinterpret_cast<void*>(
                            const_cast<A*>(
                                &a
                                )
                            )
                        ),
                    Role
                    );

// Reading
        const A &a = *reinterpret_cast<A*>(
                    const_cast<const void*>(
                        item->data(Role).value<void*>()
                        )
                    );

To copy to clipboard, switch view to plain text mode 

How bad is this ?

Anything better ?

Thanks !

PS0 : I read the method with Q_DECLARE_METATYPE.
PS1 : I could always create an intermediate Qt type which would embed my non Qt type...but that seems heavy too.
