'GI.Gtk.Objects.IconTheme.IconTheme' provides a facility for looking up icons by name
and size. The main reason for using a name rather than simply
providing a filename is to allow different icons to be used
depending on what “icon theme” is selected
by the user. The operation of icon themes on Linux and Unix
follows the <http://www.freedesktop.org/Standards/icon-theme-spec Icon Theme Specification>
There is a fallback icon theme, named @hicolor@, where applications
should install their icons, but additional icon themes can be installed
as operating system vendors and users choose.

Named icons are similar to the deprecated [Stock Items][gtkstock],
and the distinction between the two may be a bit confusing.
A few things to keep in mind:

* Stock images usually are used in conjunction with
[Stock Items][gtkstock], such as 'GI.Gtk.Constants.STOCK_OK' or
'GI.Gtk.Constants.STOCK_OPEN'. Named icons are easier to set up and therefore
are more useful for new icons that an application wants to
add, such as application icons or window icons.
* Stock images can only be loaded at the symbolic sizes defined
by the 'GI.Gtk.Enums.IconSize' enumeration, or by custom sizes defined
by 'GI.Gtk.Functions.iconSizeRegister', while named icons are more flexible
and any pixel size can be specified.
* Because stock images are closely tied to stock items, and thus
to actions in the user interface, stock images may come in
multiple variants for different widget states or writing
directions.


A good rule of thumb is that if there is a stock image for what
you want to use, use it, otherwise use a named icon. It turns
out that internally stock images are generally defined in
terms of one or more named icons. (An example of the
more than one case is icons that depend on writing direction;
'GI.Gtk.Constants.STOCK_GO_FORWARD' uses the two themed icons
“gtk-stock-go-forward-ltr” and “gtk-stock-go-forward-rtl”.)

In many cases, named themes are used indirectly, via 'GI.Gtk.Objects.Image.Image'
or stock items, rather than directly, but looking up icons
directly is also simple. The 'GI.Gtk.Objects.IconTheme.IconTheme' object acts
as a database of all the icons in the current theme. You
can create new 'GI.Gtk.Objects.IconTheme.IconTheme' objects, but it’s much more
efficient to use the standard icon theme for the 'GI.Gdk.Objects.Screen.Screen'
so that the icon information is shared with other people
looking up icons.

'GI.Gtk.Objects.IconTheme.iconThemeLookupIcon' followed by 'GI.Gtk.Objects.IconInfo.iconInfoLoadIcon'.

Note that you probably want to listen for icon theme changes and

update the icon when the icon theme changes, you should consider
using 'GI.GdkPixbuf.Objects.Pixbuf.pixbufCopy' to make a private copy of the pixbuf

icon theme loaded, which would be a waste of memory.

Looks up a named icon and returns a 'GI.Gtk.Objects.IconInfo.IconInfo' containing
information such as the filename of the icon. The icon
can then be rendered into a pixbuf using
'GI.Gtk.Objects.IconInfo.iconInfoLoadIcon'. ('GI.Gtk.Objects.IconTheme.iconThemeLoadIcon'
combines these two steps if all you need is the pixbuf.)

When rendering on displays with high pixel densities you should not
use a /@size@/ multiplied by the scaling factor returned by functions
like 'GI.Gdk.Objects.Window.windowGetScaleFactor'. Instead, you should use
'GI.Gtk.Objects.IconTheme.iconThemeLookupIconForScale', as the assets loaded
for a given scaling factor may be different.

Sets the search path for the icon theme object. When looking
for an icon theme, GTK+ will search for a subdirectory of
one or more of the directories in /@path@/ with the same name
as the icon theme containing an index.theme file. (Themes from
multiple of the path elements are combined to allow themes to be
extended by adding icons in the user’s home directory.)

In addition if an icon found isn’t found either in the current
icon theme or the default icon theme, and an image file with
the right name is found directly in one of the elements of
/@path@/, then that image will be used for the icon name.
(This is legacy feature, and new icons should be put
into the fallback icon theme, which is called hicolor,
rather than directly on the icon path.)

Gets the icon theme object associated with /@screen@/; if this
function has not previously been called for the given
screen, a new icon theme object will be created and
associated with the screen. Icon theme objects are
fairly expensive to create, so using this function
is usually a better choice than calling than 'GI.Gtk.Objects.IconTheme.iconThemeNew'
and setting the screen yourself; by using this function
a single icon theme object will be shared between users.
