When using GTK+, normally you should use <a

><code class="function">gtk_widget_get_pango_context()</code></a>
instead of this function, to get the appropriate context for
the widget you intend to render text onto.

The newly created context will have the default font options (see
<a

changes to the screen's font rendering settings.</p>
