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 Icon Theme Specification. There is a default icon theme, named hicolor where applications should install their icons, but more additional application themes can be installed as operating system vendors and users choose.
Named icons are similar to the Themeable Stock Images(3) facility, 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(3)., such as or . 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 enumeration, or by custom sizes defined by , 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; uses the two themed icons "gtk-stock-go-forward-ltr" and "gtk-stock-go-forward-rtl".)
GLib.ObjectMethodGtk.IconThemeGets the icon theme object associated with
a a . A unique associated with the given screen. This icon theme is associated with the screen and can be used as long as the screen is open.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 and setting the screen yourself; by using this function a single icon theme object will be shared between users.MethodSystem.Int32Returns an integer identifier for an error string.a MethodSystem.VoidRegisters a built-in icon for icon theme lookups.
a , the name of the icon to register
a , the size at which to register the icon (different images can be registered for the same icon name at different sizes.)
a that contains the image to use for .
The idea of built-in icons is to allow an application or library that uses themed icons to function requiring files to be present in the file system. For instance, the default images for all of Gtk's stock icons are registered as built-icons.
In general, if you use you should also install the icon in the icon theme, so that the icon is generally available.

See .PropertySystem.String[]The current search patha , array of directories that are searched for icon themes
When looking for an icon theme, Gtk will search for a
subdirectory of one or more of the directories in this
path with the same name as the icon theme. (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 is not 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 a legacy feature, and new
icons should be put into the default icon theme, which
is called DEFAULT_THEME_NAME, rather than directly on
the icon path.)
