Detailed Description
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.

void Gtk::IconSet::add_source | ( | const IconSource& | source | ) |
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.
- Parameters:
-
source A Gtk::IconSource.
Glib::RefPtr<IconSet> Gtk::IconSet::copy | ( | ) | const |
Copies icon_set by value.
- Returns:
- A new Gtk::IconSet identical to the first.

GtkIconSet* Gtk::IconSet::gobj | ( | ) |
Provides access to the underlying C instance.
const GtkIconSet* Gtk::IconSet::gobj | ( | ) | const |
Provides access to the underlying C instance.
GtkIconSet* Gtk::IconSet::gobj_copy | ( | ) | const |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
static Glib::RefPtr<IconSet> Gtk::IconSet::lookup_default | ( | const Gtk::StockID& | stock_id | ) | [static] |
Looks for an icon in the list of default icon factories.
For display to the user, you should use Gtk::Style::lookup_icon_set() on the Gtk::Style for the widget that will display the icon, instead of using this function directly, so that themes are taken into account.
- Parameters:
-
stock_id An icon name.
- Returns:
- A Gtk::IconSet, or
0

void Gtk::IconSet::reference | ( | ) | const |
Increment the reference count for this object.
You should never need to do this manually - use the object via a RefPtr instead.

IconSize | size | ||

void Gtk::IconSet::unreference | ( | ) | const |
Decrement the reference count for this object.
You should never need to do this manually - use the object via a RefPtr instead.

Glib::RefPtr< Gtk::IconSet > wrap | ( | GtkIconSet * | object, |
bool | take_copy = false |
||
) | [related] |
A Glib::wrap() method for this object.
- Parameters:
-
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.
- Returns:
- A C++ instance that wraps this C instance.
