GTK+ 3 Reference Manual: Use named icons

## Use named icons

Why. Named icons automatically adapt to theme changes, giving your application a much more integrated appearance.

Named icons can be used for window icons (see `gtk_window_set_icon_name()`) and images (see `gtk_image_set_from_icon_name()`). You can also use named icons for drag-and-drop (see `gtk_drag_source_set_icon_name()`) and in treeview cells (see the "icon-name" property).
