StyleContext.this
this
()Creates a standalone #GtkStyleContext, this style context won’t be attached to any widget, so you may want to call [gtk.style_context.StyleContext.setPath] yourself.
This function is only useful when using the theming layer separated from GTK+, if you are using #GtkStyleContext to theme #GtkWidgets, use [gtk.widget.Widget.getStyleContext] in order to get a style context ready to theme the widget.
Returns
A newly created #GtkStyleContext.
