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.
Functions
g_themed_icon_new ()
GIcon *
g_themed_icon_new (const char *iconname);
Creates a new themed icon for iconname
.
g_themed_icon_new_from_names ()
GIcon * g_themed_icon_new_from_names (char **iconnames,int len);
Creates a new themed icon for iconnames
.
Parameters
iconnames |
an array of strings containing icon names. |
[array length=len] |
len |
the length of the |
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 |
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"); |
g_themed_icon_prepend_name ()
void g_themed_icon_prepend_name (GThemedIcon *icon,const char *iconname);
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().
Since 2.18
g_themed_icon_append_name ()
void g_themed_icon_append_name (GThemedIcon *icon,const char *iconname);
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().
g_themed_icon_get_names ()
const gchar * const *
g_themed_icon_get_names (GThemedIcon *icon);
Gets the names of icons from within icon
.
Property Details
The “names” property
“names” GStrv
A NULL-terminated array of icon names.
Flags: Read / Write / Construct Only
The “use-default-fallbacks” property
“use-default-fallbacks” gboolean
Whether to use the default fallbacks found by shortening the icon name at '-' characters. If the "names" array has more than one element, ignores any past the first.
For example, if the icon name was "gnome-dev-cdrom-audio", the array would become
1 2 3 4 5 6 7 |
{ "gnome-dev-cdrom-audio", "gnome-dev-cdrom", "gnome-dev", "gnome", NULL }; |
Flags: Read / Write / Construct Only
Default value: FALSE
