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.
| source | A Gtk::IconSource. |

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. |
| void Gtk::IconSet::swap | ( | IconSet& | other | ) |
| Gtk::IconSet wrap | ( | GtkIconSet * | object, | |
| bool | take_copy = false | |||
| ) | [related] |
A Glib::wrap() method for this object.
| object | The C instance. | |
| take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
