git grep GtkTextView vcl/

should give you some hints, the gtk3 case either creates widgets using
.ui files ("welded" case) or using the VclBuilder (non-welded case).

Keyboard input is typically handled by the KeyInput() virtual member
function of vcl::Window subclasses. See include/vcl/weld.hxx for the
interface that is an abstraction on top of the gtk3 and vcl (non-gtk3)
cases.

A typical Writer/Calc/Impress document content is presented using custom
widgets in gtk3 terms, so it's rare that a GtkTextView content would be
really saved to a file as-is.

Perhaps ask something more specific, so you can get specific answers.
