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:
sourceA Gtk::IconSource.
Glib::RefPtr<IconSet> Gtk::IconSet::copy ( ) const

Copies icon_set by value.

Returns:
A new Gtk::IconSet identical to the first.

static Glib::RefPtr<IconSet> Gtk::IconSet::create ( ) [static]
std::vector<IconSize> Gtk::IconSet::get_sizes ( ) const
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_idAn icon name.
Returns:
A Gtk::IconSet, or 0.
void Gtk::IconSet::operator delete ( void *  ,
size_t   
) [protected]
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.

Glib::RefPtr<Gdk::Pixbuf> Gtk::IconSet::render_icon_pixbuf ( const Glib::RefPtr< StyleContext >&  context,
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:
objectThe C instance.
take_copyFalse if the result should take ownership of the C instance. True if it should take a new copy or ref.
Returns:
