TextView.setBuffer
void setBuffer(gtk.text_buffer.TextBuffer buffer = null)Sets buffer as the buffer being displayed by text_view. The previous buffer displayed by the text view is unreferenced, and a reference is added to buffer. If you owned a reference to buffer before passing it to this function, you must remove that reference yourself; #GtkTextView will not “adopt” it.
Parameters
buffer | a #GtkTextBuffer |
