class Gio::ThemedIcon

Overview

#GThemedIcon is an implementation of #GIcon that supports icon themes. #GThemedIcon contains a list of all of the icons present in an icon theme, so that icons can be looked up quickly. #GThemedIcon does not provide actual pixmaps for icons, just the icon names. Ideally something like gtk_icon_theme_choose_icon() should be used to resolve the list of names so that fallback icons work nicely with themes that inherit other themes.

Constructor Detail

def self.new(iconname : String) : self #

Creates a new themed icon for @iconname.


def self.new #

Initialize a new ThemedIcon.


def self.new(*, name : String? = nil, names : Enumerable(String)? = nil, use_default_fallbacks : Bool? = nil) #

def self.new_from_names(iconnames : Enumerable(String)) : self #

Creates a new themed icon for @iconnames.


def self.new_with_default_fallbacks(iconname : String) : self #

Creates a new themed icon for @iconname, and all the names that can be created by shortening @iconname at '-' characters.

In the following example, @icon1 and @icon2 are equivalent: |[ const char *names[] = { "gnome-dev-cdrom-audio", "gnome-dev-cdrom", "gnome-dev", "gnome" };

icon1 = g_themed_icon_new_from_names (names, 4); icon2 = g_themed_icon_new_with_default_fallbacks ("gnome-dev-cdrom-audio"); ]|


Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


def self.new_from_names(*iconnames : String) #

Instance Method Detail

def append_name(iconname : String) : Nil #

Append a name to the list of icons from within @icon.

Note that doing so invalidates the hash computed by prior calls to g_icon_hash().


def name=(value : String) : String #

def names : Enumerable(String) #

Gets the names of icons from within @icon.


def names=(value : Enumerable(String)) : Enumerable(String) #

def prepend_name(iconname : String) : Nil #

Prepend a name to the list of icons from within @icon.

Note that doing so invalidates the hash computed by prior calls to g_icon_hash().


def use_default_fallbacks=(value : Bool) : Bool #

def use_default_fallbacks? : Bool #
