<title>Using GTK+ on DirectFB</title>

<para>
The DirectFB port of GTK+ is an implementation of GDK (and therefore GTK+) 
on top of the <ulink url="http://www.directfb.org">DirectFB</ulink> 
libraries.
</para>

<para>
Like the obsolete linux-fb port of GTK+, it runs on the Linux framebuffer,
but the DirectFB libraries provide additional features like hardware graphics 
acceleration, input device handling and abstraction and an integrated windowing 
system.
</para>

<refsect2><title>Build requirements</title>

<para>
Beyond the usual GTK+ build requirements, the DirectFB backend (obviously) 
needs the DirectFB libraries (at least 0.9.21) and cairo compiled with 
DirectFB support.
