Hi,
is it possible to write Programms that work with only framebuffer?
I think, mazbe I can link it against gtk+direktFB.

I think that noone has tryed that before, the only way to find out is
testing!

If the gtk 1 interface doesn't work you can also try gtk2 and qt
interfaces.

are GTk2 and QT interfaces already working?

Quote from: "angman"are GTk2 and QT interfaces already working?

There is only one big bad bug on Gtk2 interface that prevents Lazarus
from working correctly with it (autosize is wrong and freezes some
dialogs).

Aside from that it should work for most applications you develop.

Qt 4 has most controls working, but is very new, so everything is a
little incomplete. It works good on Linux, Windows and Mac OS X. With
some small changes it can also work for Qtopia on Framebuffer.

If this works, I would be very interested in it for development of
embedded displays. It would be awsome to be able to display simple
gui's without a full X installation in Ramdisk based setups.

What would be thre process to link to another GTK library such as GTK-
DFB?

I went to google and put the string "How to link gtk for directfb",
and it gives 2 very good links

I think you don´t have to change your software. You only need to
recompile Gtk and all other needed libraries with some special
options, and that should be it. But I could be wrong.

Someone will need to test this. And if you do, please tell us how you
made it work =) A wiki article with a tutorial would be nice.

I might just try it. It might take a little while as I need to set up
a box to host builds for semi embedded ram disk based systems. I might
try to add gtk-FB to it as well. I'm wondering though how fonts will
be dealt with, if I still need a font server. It would be nice if I
could use simple font files...something to investigate when I get to
that point.

I will definatly post and make a write-up if I succeed as I belive
this might be of use for embedded stuff for other people.

I know this is an ancient thread, but because of it's name I want to
add some not mentioned framebuffer based alternative libraries so one
does not loose time searching like I already have. This is just a
collected list, not something tested. Please feel free to correct or
add anything I missed.
