public virtual SizeRequestMode get_request_mode ()
Gets whether the widget prefers a height-for-width layout or a width-for-height layout.
Single-child widgets generally propagate the preference of their child, more complex widgets need to request something either in context of their children or in context of their allocation capabilities.
