<p>Creates a new icon theme object. Icon theme objects are used
to lookup up an icon by name in a particular icon theme.

<p>Looks up an icon in an icon theme, scales it to the given size

if more details about the icon are needed, use

<p>Note that you probably want to listen for icon theme changes and
update the icon. This is usually done by connecting to the
GtkWidget::style-set signal. If for some reason you do not want to
update the icon when the icon theme changes, you should consider
using <a href="http://library.gnome.org/devel/gdk-pixbuf/unstable/gdk-pixbuf-Image-Data-in-Memory.html#gdk-pixbuf-copy"><code class="function">gdk_pixbuf_copy()</code></a> to make a private copy of the pixbuf
returned by this function. Otherwise GTK+ may need to keep the old
icon theme loaded, which would be a waste of memory.</p>

<p>Raw coordinates are somewhat strange; they are specified to be with
respect to the unscaled pixmap for PNG and XPM icons, but for SVG
icons, they are in a 1000x1000 coordinate space that is scaled
to the final size of the icon. You can determine if the icon is an SVG
icon by using <a class="link" href="GtkIconTheme.html#gtk-icon-info-get-filename" title="gtk_icon_info_get_filename"><code class="function">gtk_icon_info_get_filename()</code></a>, and seeing if it is non-<code class="literal">NULL</code>
and ends in '.svg'.</p>
<p>This function is provided primarily to allow compatibility wrappers
for older API's, and is not expected to be useful for applications.</p>

</pre>
<p>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 <em class="parameter"><code>path</code></em>
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.)</p>
<p>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
<em class="parameter"><code>path</code></em>
, then that image will be used for the icon name.
(This is 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.)</p>
