This manages a set of variants of a particular icon An 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 GtkStyle has a list of GtkIconFactory 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 gtk_icon_factory_add_default() and gtk_icon_factory_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.

Icon sets have a list of Gtk::IconSource, which they use as base icons for rendering icons in different states and sizes. Icons are scaled, made to look insensitive, etc. in render_icon(), but Gtk::IconSet needs base images to work with. The base images and when to use them are described by a Gtk::IconSource.
This function copies source, so you can reuse the same source immediately without affecting the icon set.
An example of when you'd use this function: a web browser's "Back to Previous Page" icon might point in a different direction in Hebrew and in English; it might look different when insensitive; and it might change size depending on toolbar mode (small/large icons). So a single icon set would contain all those variants of the icon, and you might add a separate source for each one.
You should nearly always add a "default" icon source with all fields wildcarded, which will be used as a fallback if no more specific source matches. Gtk::IconSet always prefers more specific icon sources to more generic icon sources. The order in which you add the sources to the icon set does not matter.
new_from_pixbuf() creates a new icon set with a default icon source based on the given pixbuf.

For display to the user, you should use Style::lookup_icon_set() on the Style for the widget that will display the icon, instead of using this function directly, so that themes are taken into account

Renders an icon using Gtk::Style::render_icon(). In most cases, Gtk::Widget::render_icon() is better, since it automatically provides most of the arguments from the current widget settings. This function never returns 0
; if the icon can't be rendered (perhaps because an image file fails to load), a default "missing
image" icon will be returned instead.
style | A Gtk::Style associated with widget, or 0 . |
direction | Text direction. |
state | Widget state. |
size | Icon size. A size of (GtkIconSize)-1 means render at the size of the source and don't scale. |
widget | Widget that will display the icon, or 0 . The only use that is typically made of this is to determine the appropriate Gdk::Screen. |
detail | Detail to pass to the theme engine, or 0 . Note that passing a detail of anything but 0 will disable caching. |

take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
