Default behavior

[Igor Korot <ikorot01 gmail com>]

 Hi, ALL,
In GTK+ there is a function gtk_text_view_set_accepts_tab ().

However there is no indication as with many others - what is the
default behavior is
in the documentation. (ref.
https://developer.gnome.org/gtk3/stable/GtkTextView.html#gtk-text-view-set-accepts-tab).

So, if I don't call this function - what is the default?

Thank you.

P.S.: It would be nice if the documentation explicitly mention default behavior
of every GTK+ call, but I guess it is too much to ask. ;-)
