add_builtin_icon

function add_builtin_icon(icon_name:String, size:Number, pixbuf:GdkPixbuf.Pixbuf):void {
    // Gjs wrapper for gtk_icon_theme_add_builtin_icon()
}

Registers a built-in icon for icon theme lookups. 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 add_builtin_icon you should also install the icon in the icon theme, so that the icon is generally available.

This function will generally be used with pixbufs loaded via GdkPixbuf.new_from_inline.
