set_buffer
Description:
Sets buffer as the buffer being displayed by this.
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:
| this |
a `GtkTextView` |
| buffer |
a `GtkTextBuffer` |
