<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>
|
||
|
|
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.

FIXME: it seems most of the options listed in _gdk_windowing_args
|
||
|
|
are ignored, and they need to be described by somebody who knows
|

|
|
what they are supposed to do...
