a list of <a href="class-gtkiconsource.html" title="gtk.IconSource"><tt class="classname">gtk.IconSource</tt></a>,

by a <a href="class-gtkiconsource.html" title="gtk.IconSource"><tt class="classname">gtk.IconSource</tt></a>.</p><p>An example of when you'd use this method: a web browser's
"<span class="guibutton">Back to Previous Page</span>" 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
or 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 href="class-gtkiconset.html" title="gtk.IconSet"><tt class="classname">gtk.IconSet</tt></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>The <a href="class-gtkiconset.html#constructor-gtkiconset" title="Constructor"><tt class="methodname">gtk.IconSet</tt>()</a>
