Warning: IconFactory is deprecated since 3.10. Use IconTheme.

An icon factory manages a collection of IconSet; a IconSet manages a set of variants of a particular icon (i.

e. a IconSet contains variants for different sizes and widget states). Icons in an icon factory are named by a stock ID, which is a simple string identifying the icon. Each Style has a list of IconFactory derived from the current theme; those icon factories are consulted first when searching for an icon. If the theme doesn’t set a particular icon, GTK+ looks for the icon in a list of default icon factories, maintained by add_default and remove_default. Applications with icons should add a default icon factory with their icons, which will allow themes to override the icons for the application.

To display an icon, always use lookup_icon_set on the widget that will display the icon, or the convenience function render_icon. These functions take the theme into account when looking up the icon to use for a given stock ID.
