## Implemented Interfaces

GThemedIcon implements GIcon.

## Includes

    #include <gio/gio.h>

## Description

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.

    g_themed_icon_new (const char *iconname);

                                  int len);

### g_themed_icon_new_with_default_fallbacks ()

    GIcon *
    g_themed_icon_new_with_default_fallbacks
                                   (const char *iconname);

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:

    1
    2
    3
    4
    5
    6
    7
    8
    9

      "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");

#### Parameters

iconname | a string containing an icon name |
