Struct gio::ThemedIcon [−][src]
pub struct ThemedIcon(_);
Expand description
ThemedIcon
is an implementation of Icon
that supports icon themes.
ThemedIcon
contains a list of all of the icons present in an icon
theme, so that icons can be looked up quickly. ThemedIcon
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.
Implements
Implementations
Creates a new themed icon for iconname
.
iconname
a string containing an icon name.
Returns
a new ThemedIcon
.
Creates a new themed icon for iconnames
.
iconnames
an array of strings containing icon names.
Returns
a new ThemedIcon
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:
⚠️ The following code is in C ⚠️
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 ThemedIcon
.
Append a name to the list of icons from within self
.
Note that doing so invalidates the hash computed by prior calls
to g_icon_hash()
.
iconname
name of icon to append to list of icons from within self
.
Prepend a name to the list of icons from within self
.
Note that doing so invalidates the hash computed by prior calls
to g_icon_hash()
.
iconname
name of icon to prepend to list of icons from within self
.
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
⚠️ The following code is in C ⚠️
{
"gnome-dev-cdrom-audio",
"gnome-dev-cdrom",
"gnome-dev",
"gnome",
NULL
};
