defined. An example implementation will be committed soon.

/**
* gtk_style_context_get_section:
* @context: a #GtkStyleContext
* @property: style property name
*
* Queries the location in the CSS where @property was defined for the
* current @context. Note that the state to be queried is taken from
* gtk_style_context_get_state().
*
* If the location is not available, %NULL will be returned. The
* location might not be available for various reasons, such as the
* property being overridden, @property not naming a supported CSS
* property or tracking of definitions being disabled for performance
* reasons.
*
* Shorthand CSS properties cannot be queried for a location and will
* always return %NULL.
*
* Returns: %NULL or the section where value was defined
