<pre class="programlisting">struct GdkPangoRenderer;</pre>
<p><a class="link" href="gdk2-Pango-Interaction.html#GdkPangoRenderer"><span class="type">GdkPangoRenderer</span></a> is a subclass of <a href="https://developer.gnome.org/pango/PangoRenderer.html#PangoRenderer-struct"><span class="type">PangoRenderer</span></a> used for rendering
Pango objects into GDK drawables. The default renderer for a particular
screen is obtained with <a class="link" href="gdk2-Pango-Interaction.html#gdk-pango-renderer-get-default" title="gdk_pango_renderer_get_default ()"><code class="function">gdk_pango_renderer_get_default()</code></a>; Pango
functions like <a href="https://developer.gnome.org/pango/PangoRenderer.html#pango-renderer-draw-layout"><code class="function">pango_renderer_draw_layout()</code></a> and
<a href="https://developer.gnome.org/pango/PangoRenderer.html#pango-renderer-draw-layout-line"><code class="function">pango_renderer_draw_layout_line()</code></a> are then used to draw objects with
the renderer.</p>
<p>In most simple cases, applications can just use <a class="link" href="gdk2-Drawing-Primitives.html#gdk-draw-layout" title="gdk_draw_layout ()"><code class="function">gdk_draw_layout()</code></a>, and
don't need to directly use <a class="link" href="gdk2-Pango-Interaction.html#GdkPangoRenderer"><span class="type">GdkPangoRenderer</span></a> at all. Using the
<a class="link" href="gdk2-Pango-Interaction.html#GdkPangoRenderer"><span class="type">GdkPangoRenderer</span></a> directly is most useful when working with a
transformation such as a rotation, because the Pango drawing functions
take user space coordinates (coordinates before the transformation)
instead of device coordinates.</p>
<p>In certain cases it can be useful to subclass <a class="link" href="gdk2-Pango-Interaction.html#GdkPangoRenderer"><span class="type">GdkPangoRenderer</span></a>. Examples
of reasons to do this are to add handling of custom attributes by
overriding 'prepare_run' or to do custom drawing of embedded objects
by overriding 'draw_shape'.</p>
