class Gio::ThemedIcon

Overview

GThemedIcon is an implementation of Gio::Icon 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::IconTheme#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 = nil, names : Enumerable(String) | Nil = nil, use_default_fallbacks : Bool | Nil = 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 ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


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 hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def name=(value : String) : String #

def name=(value : Nil) : Nil #

Set #name property to nil.


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 #
