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.

typedef struct _GThemedIcon GThemedIcon;

An implementation of GIcon for themed icons.


g_themed_icon_new ()

GIcon *             g_themed_icon_new                   (const char *iconname);

Creates a new themed icon for iconname.

iconname :

a string containing an icon name.

Returns :

a new GThemedIcon.. transfer full.

g_themed_icon_new_from_names ()

GIcon *             g_themed_icon_new_from_names        (char **iconnames,
                                                         int len);

Creates a new themed icon for iconnames.

iconnames :

an array of strings containing icon names.. array length=len.

len :

the length of the iconnames array, or -1 if iconnames is NULL-terminated

Returns :

a new GThemedIcon. transfer full.

g_themed_icon_new_with_default_fallbacks ()

GIcon *             g_themed_icon_new_with_default_fallbacks
                                                        (const char *iconname);

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");

iconname :

a string containing an icon name

Returns :

a new GThemedIcon.. transfer full.

g_themed_icon_prepend_name ()

void                g_themed_icon_prepend_name          (GThemedIcon *icon,
