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](http://www.freedesktop.org/Standards/icon-theme-spec) * 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 %GTK_STOCK_OK or * %GTK_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 #GtkIconSize enumeration, or by custom sizes defined * by gtk_icon_size_register(), 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; * %GTK_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 #GtkImage * or stock items, rather than directly, but looking up icons * directly is also simple. The #GtkIconTheme object acts * as a database of all the icons in the current theme. You * can create new #GtkIconTheme objects, but it’s much more * efficient to use the standard icon theme for the #GdkScreen * so that the icon information is shared with other people * looking up icons. * |[ * GError *error = NULL;
