c++ - Gsv::buffer error -

in c++ project, want use gsv::buffer gtksourceview library. declare buffer this:

glib::refptr<gsv::buffer> buffer; 

i create :

buffer->create(); 

but when want use inherited fonction gtk::buffer:

 buffer->set_text("somethings"); 

the executable exit , return:

erreur de segmentation (core dumped)

what problem?

thanks help

you create pointer, don't make point anywhere. in essence, buffer null pointer.

from the refptr default constructor refernece:

afterwards null , use of -> cause segmentation fault.

you need explicitly create object pointed to, using static gsv::buffer::create function, e.g.

glib::refptr<gsv::buffer> buffer = gsv::buffer::create();
