Re: how to handle an array of Pixbuf?

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

How do you transfer the array from the creating method to the painting 
method? With arrays it's easy to (by mistake) copy a pointer to the 
array when you should have copied the whole array. A std::vector is 
often safer,

std::vector< Glib::RefPtr<Gdk::Pixbuf> > image2(3);
