()Creates a new #GtkSourceView.
By default, an empty #GtkSourceBuffer will be lazily created and can be retrieved with [gtk.text_view.TextView.getBuffer].
If you want to specify your own buffer, either override the #GtkTextViewClass create_buffer factory method, or use [gtksource.view.View.newWithBuffer].
Returns
a new #GtkSourceView.
