169 * gtk_icon_factory_new:
171 * Creates a new #GtkIconFactory. An icon factory manages a collection
172 * of #GtkIconSet<!-- -->s; a #GtkIconSet manages a set of variants of a
173 * particular icon (i.e. a #GtkIconSet contains variants for different
174 * sizes and widget states). Icons in an icon factory are named by a
175 * stock ID, which is a simple string identifying the icon. Each
176 * #GtkStyle has a list of #GtkIconFactory<!-- -->s derived from the current
177 * theme; those icon factories are consulted first when searching for
178 * an icon. If the theme doesn't set a particular icon, GTK+ looks for
179 * the icon in a list of default icon factories, maintained by
180 * gtk_icon_factory_add_default() and
181 * gtk_icon_factory_remove_default(). Applications with icons should
182 * add a default icon factory with their icons, which will allow
183 * themes to override the icons for the application.

199 * Adds the given @icon_set to the icon factory, under the name
200 * @stock_id. @stock_id should be namespaced for your application,
201 * e.g. "myapp-whatever-icon". Normally applications create a
202 * #GtkIconFactory, then add it to the list of default factories with
203 * gtk_icon_factory_add_default(). Then they pass the @stock_id to
204 * widgets such as #GtkImage to display the icon. Themes can provide
205 * an icon with the same name (such as "myapp-whatever-icon") to
206 * override your application's default icons. If an icon already
207 * existed in @factory for @stock_id, it is unreferenced and replaced

1857 * which it derives all variants. The convenience function
