The path is simply the name of a widget and all its parents in the container hierarchy, separated by periods. The name of a widget comes from Widget.Name. Paths are used to apply styles to a widget in gtkrc configuration files. Widget names are the type of the widget by default (e.g. "Gtk.Button") or can be set to an application-specific value with Widget.Name.
By setting the name of a widget, you allow users or theme authors to apply styles to that specific widget in their gtkrc file. path_reversed_p fills in the path in reverse order, i.e. starting with widget's name instead of starting with the name of widget's outermost ancestor.
