If you create and keep a PangoLayout using this context, you must deal with changes to the context by calling pangoLayoutContextChanged on the layout in response to the "style-set" and "direction-changed" signals for the widget.

Unlike the context returned by gtkWidgetCreatePangoContext, this context is owned by the widget (it can be used until the screen for the widget changes or the widget is removed from its toplevel), and will be updated to match any changes to the widget's attributes.
