I have a class derived from Fl_Double_Window.

That Fl_Double_Window has a Fl_Group that ends up holding an Fl_Text_Display.

The class also has a Fl_Text_Buffer associated with the Fl_Text_Display.

I am working on the destructor for my class.

If I call delete on the Fl_Text_Buffer, then the Buffer is destroyed before the Fl_Text_Display destructor gets called (through the Fl_Double_Window and Fl_Group destructors).

I've tried setting the Fl_Text_Display's buffer to NULL before destructing the buffer.  This seems to 'work', but also seems extremely hacky.

Foo::~Foo()

{

    m_Display->buffer( NULL );

    delete m_Buffer;

}

Is this the proper way to clean up in this situation?

I might be able to make the Fl_Text_Buffer a direct member variable (instead of a pointer allocated with new), but I can still imagine situations where this would arise.

Am I missing something?
