<a name="gtk3-GtkWidgetPath.description"></a><h2>Description</h2>
<p>GtkWidgetPath is a boxed type that represents a widget hierarchy from
the topmost widget, typically a toplevel, to any child. This widget
path abstraction is used in <a class="link" href="GtkStyleContext.html" title="GtkStyleContext"><span class="type">GtkStyleContext</span></a> on behalf of the real
widget in order to query style information.</p>
<p>If you are using GTK+ widgets, you probably will not need to use
this API directly, as there is <a class="link" href="GtkWidget.html#gtk-widget-get-path" title="gtk_widget_get_path ()"><code class="function">gtk_widget_get_path()</code></a>, and the style
context returned by <a class="link" href="GtkWidget.html#gtk-widget-get-style-context" title="gtk_widget_get_style_context ()"><code class="function">gtk_widget_get_style_context()</code></a> will be automatically
updated on widget hierarchy changes.</p>
<p>The widget path generation is generally simple:</p>
