IconSet.this

Creates a new #GtkIconSet. A #GtkIconSet represents a single icon in various sizes and widget states. It can provide a #GdkPixbuf for a given size and state on request, and automatically caches some of the rendered #GdkPixbuf objects.

Normally you would use [gtk.widget.Widget.renderIconPixbuf] instead of using #GtkIconSet directly. The one case where you’d use #GtkIconSet is to create application-specific icon sets to place in a #GtkIconFactory.
