<p>Creates a new <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconFactory"><span class="type">GtkIconFactory</span></a>. An icon factory manages a collection

particular icon (i.e. a <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSet"><span class="type">GtkIconSet</span></a> contains variants for different
sizes and widget states). Icons in an icon factory are named by a
stock ID, which is a simple string identifying the icon. Each
<a class="link" href="GtkStyle.html" title="GtkStyle"><span class="type">GtkStyle</span></a> has a list of <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconFactory"><span class="type">GtkIconFactory</span></a>s derived from the current
theme; those icon factories are consulted first when searching for
an icon. If the theme doesn't set a particular icon, GTK+ looks for
the icon in a list of default icon factories, maintained by

gtk_icon_set_add_source (<em class="parameter"><code><a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSet"><span class="type">GtkIconSet</span></a> *icon_set</code></em>,
<em class="parameter"><code>const <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSource" title="GtkIconSource"><span class="type">GtkIconSource</span></a> *source</code></em>);</pre>
<p>Icon sets have a list of <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSource" title="GtkIconSource"><span class="type">GtkIconSource</span></a>, which they use as base
icons for rendering icons in different states and sizes. Icons are
scaled, made to look insensitive, etc. in
<a class="link" href="gtk2-Themeable-Stock-Images.html#gtk-icon-set-render-icon" title="gtk_icon_set_render_icon ()"><code class="function">gtk_icon_set_render_icon()</code></a>, but <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSet"><span class="type">GtkIconSet</span></a> needs base images to
work with. The base images and when to use them are described by
a <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSource" title="GtkIconSource"><span class="type">GtkIconSource</span></a>.</p>
<p>This function copies <em class="parameter"><code>source</code></em>
, so you can reuse the same source immediately
without affecting the icon set.</p>
<p>An example of when you'd use this function: a web browser's "Back
to Previous Page" icon might point in a different direction in
Hebrew and in English; it might look different when insensitive;
and it might change size depending on toolbar mode (small/large
icons). So a single icon set would contain all those variants of
the icon, and you might add a separate source for each one.</p>
<p>You should nearly always add a "default" icon source with all
fields wildcarded, which will be used as a fallback if no more
specific source matches. <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSet"><span class="type">GtkIconSet</span></a> always prefers more specific
icon sources to more generic icon sources. The order in which you
add the sources to the icon set does not matter.</p>
<p>gtk_icon_set_new_from_pixbuf() creates a new icon set with a

gtk_icon_source_new (<em class="parameter"><code><span class="type">void</span></code></em>);</pre>
<p>Creates a new <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSource" title="GtkIconSource"><span class="type">GtkIconSource</span></a>. A <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSource" title="GtkIconSource"><span class="type">GtkIconSource</span></a> contains a <a href="http://library.gnome.org/devel/gdk-pixbuf/unstable/gdk-pixbuf-The-GdkPixbuf-Structure.html#GdkPixbuf-struct"><span class="type">GdkPixbuf</span></a> (or
image filename) that serves as the base image for one or more of the
icons in a <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSet"><span class="type">GtkIconSet</span></a>, along with a specification for which icons in the
icon set will be based on that pixbuf or image file. An icon set contains
a set of icons that represent "the same" logical concept in different states,
different global text directions, and different sizes.</p>
<p>So for example a web browser's "Back to Previous Page" icon might
point in a different direction in Hebrew and in English; it might
look different when insensitive; and it might change size depending
on toolbar mode (small/large icons). So a single icon set would
contain all those variants of the icon. <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSet"><span class="type">GtkIconSet</span></a> contains a list
of <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSource" title="GtkIconSource"><span class="type">GtkIconSource</span></a> from which it can derive specific icon variants in
the set.</p>
<p>In the simplest case, <a class="link" href="gtk2-Themeable-Stock-Images.html#GtkIconSet"><span class="type">GtkIconSet</span></a> contains one source pixbuf from
which it derives all variants. The convenience function
<a class="link" href="gtk2-Themeable-Stock-Images.html#gtk-icon-set-new-from-pixbuf" title="gtk_icon_set_new_from_pixbuf ()"><code class="function">gtk_icon_set_new_from_pixbuf()</code></a> handles this case; if you only have
one source pixbuf, just use that function.</p>
<p>If you want to use a different base pixbuf for different icon
variants, you create multiple icon sources, mark which variants
they'll be used to create, and add them to the icon set with
<a class="link" href="gtk2-Themeable-Stock-Images.html#gtk-icon-set-add-source" title="gtk_icon_set_add_source ()"><code class="function">gtk_icon_set_add_source()</code></a>.</p>
<p>By default, the icon source has all parameters wildcarded. That is,
the icon source will be used as the base icon for any desired text
direction, widget state, or icon size.</p>
