<a class="link" href="GtkSettings.html" title="Settings"><span class="type">GtkSettings</span></a>. Normally <em class="parameter"><code>size</code></em> would be
<span class="type">GTK_ICON_SIZE_MENU</span>, <span class="type">GTK_ICON_SIZE_BUTTON</span>, etc.  This function
isn't normally needed, <a class="link" href="GtkWidget.html#gtk-widget-render-icon"><code class="function">gtk_widget_render_icon()</code></a> is the usual
way to get an icon for rendering, then just look at the size of
the rendered pixbuf. The rendered pixbuf may not even correspond to
the width/height returned by <a class="link" href="gtk-Themeable-Stock-Images.html#gtk-icon-size-lookup"><code class="function">gtk_icon_size_lookup()</code></a>, because themes
are free to render the pixbuf however they like, including changing
the usual size.</p>
