Buffer.setStyleScheme

Sets a classStyleScheme to be used by the buffer and the view.

Note that a classStyleScheme affects not only the syntax highlighting, but also other classView features such as highlighting the current line, matching brackets, the line numbers, etc.

Instead of setting a null scheme, it is better to disable syntax highlighting with [gtksource.buffer.Buffer.setHighlightSyntax], and setting the classStyleScheme with the "classic" or "tango" ID, because those two style schemes follow more closely the GTK theme (for example for the background color).

The buffer holds a reference to scheme.
