61 * @Short_description: Looking up icons by name
62 * @Title: GtkIconTheme
64 * #GtkIconTheme provides a facility for looking up icons by name
65 * and size. The main reason for using a name rather than simply
66 * providing a filename is to allow different icons to be used
67 * depending on what <firstterm>icon theme</firstterm> is selected
68 * by the user. The operation of icon themes on Linux and Unix
70 * url="http://www.freedesktop.org/Standards/icon-theme-spec">Icon
71 * Theme Specification</ulink>. There is a default icon theme,
72 * named <literal>hicolor</literal> where applications should install
73 * their icons, but more additional application themes can be
74 * installed as operating system vendors and users choose.
76 * Named icons are similar to the <xref linkend="gtk3-Themeable-Stock-Images"/>
77 * facility, and the distinction between the two may be a bit confusing.
78 * A few things to keep in mind:
81 * Stock images usually are used in conjunction with
82 * <xref linkend="gtk3-Stock-Items"/>, such as %GTK_STOCK_OK or
83 * %GTK_STOCK_OPEN. Named icons are easier to set up and therefore
84 * are more useful for new icons that an application wants to
85 * add, such as application icons or window icons.
88 * Stock images can only be loaded at the symbolic sizes defined
89 * by the #GtkIconSize enumeration, or by custom sizes defined
90 * by gtk_icon_size_register(), while named icons are more flexible
91 * and any pixel size can be specified.
94 * Because stock images are closely tied to stock items, and thus
95 * to actions in the user interface, stock images may come in
96 * multiple variants for different widget states or writing
100 * A good rule of thumb is that if there is a stock image for what
101 * you want to use, use it, otherwise use a named icon. It turns
102 * out that internally stock images are generally defined in
103 * terms of one or more named icons. (An example of the
104 * more than one case is icons that depend on writing direction;
105 * %GTK_STOCK_GO_FORWARD uses the two themed icons
106 * "gtk-stock-go-forward-ltr" and "gtk-stock-go-forward-rtl".)
108 * In many cases, named themes are used indirectly, via #GtkImage
109 * or stock items, rather than directly, but looking up icons
110 * directly is also simple. The #GtkIconTheme object acts
111 * as a database of all the icons in the current theme. You
112 * can create new #GtkIconTheme objects, but its much more
113 * efficient to use the standard icon theme for the #GdkScreen
114 * so that the icon information is shared with other people
115 * looking up icons. In the case where the default screen is
116 * being used, looking up an icon can be as simple as:
119 * GError *error = NULL;
120 * GtkIconTheme *icon_theme;
123 * icon_theme = gtk_icon_theme_get_default ();
124 * pixbuf = gtk_icon_theme_load_icon (icon_theme,
125 * "my-icon-name", // icon name
131 * g_warning ("Couldn't load icon: %s", error->message);
132 * g_error_free (error);
137 * g_object_unref (pixbuf);
