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

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