[C++]Use Glib::RefPtr<> with my own classes ?

[Aurélien Ansel <camumus gmail com>]

Hi everyone,
my english is not perfect, sorry in advance for that.

I try to use Glib::RefPtr<> with my own classes.
I have seen in the docs that Glib::RefPtr is the smart pointers for the Glib::Object subclasses, subclasses that wraps C functionalities of the Glib, is it ?

I have developped my main class in order to subclass it with my other classes :

class Referencable
{
public:
    void reference();
    void unreference();

protected:
    Referencable():_ref_counter(1) {}
    virtual ~Referencable() {}

private:
    unsigned long long _ref_counter;
};

the 2 main methods :

void Referencable::reference() {
    ++_ref_counter;
}

void Referencable::unreference() {
    --_ref_counter;
    if (_ref_counter == 0)
        delete this;
}

I have tested it, that seems to work, but after developped many subclasses with it, i had some problems with invalids Glib::RefPtr that are destroyed "too soon".

My questions are : is it possible to use Glib::RefPtr<> with classes that aren't from Glib C ?
If yes, someone have an idea what is wrong with my code ?

Thanksfully,
Aurelien
