Storing template classes

GrahamL

Hi
So I have a templated class
@
template<typename T>
class MyClass
{
....
}
@

Is it possible to have a list of these?
I'm guessing not as this does not compile
@
QList<MyClass<T> > myList;
@

Is there a way of achieving this?

Thanks

Hi,

What error are you getting ?

For example
@QList< QVector<int> > myList;@

Builds without any problem

Hi
I am trying to store the templated class not the instantiations

@
QList<MyClass<T> > myList;
@

The error is T : undeclared identifier

SGaist

Ok, that, AFAIK no you can't store a template class

What's your use case ?

GrahamL

Hi
Thats what I thought

I want to associate a string with a particular instantiation of the template class

SGaist

What would be the end-result ?

GrahamL

Hi

I think I will have to find another way

Thanks anyway

The solution is to derive the template from a base class
@
class Base
{
Base() {}
~Base() {}
};

template<class T>
class MyTemplate : public Base
{
MyTemplate() {}
~MyTemplate() {}
};

class MyStore
{
QList<const Base*> m_list;
}
