Arun,
Besides QT, you can try with DFB + GTK on DFB. Anyway having an X
based GUI is not a big deal considering the hardware performance and
storage capacities on any embedded device running an OMAP3x processor.
We have ported DFB, GTK and Webkit/Gtk to the EVM and they run pretty
well.
However you need to consider that if in the future (or now) you want
to take advantage of the hardware acceleration (SGX hardware) for
rendering with 3D capabilities any of this technologies may have
problems integrating OpenGL ES renderings (because there is not
standard OGLES stack for Linux, so there is no _simple_ way to
integrate it with existing X extension, or any of the other stacks,
beyond having a OGL surface withint all your standard widgets). A good
approach on this case is to use clutter (clutter-project.org) to
create rich UIs, but at this point you will find this software stack a
little bit lacking for any other input than a touchscreen (nothing
that cannot be solved in the future). We have done some work
integrating clutter with experimental OGLES drivers and it works
perfectly on the EVM.

Hi All,
I want to have a GUI on OMAP3EVM.
Basically I am looking for a GUI stack that can work on top of linux
framebuffer
device(Eg: DirectFb).
X window based GUI is not suitable for embedded
devices, am I right?
Does any body tried this?
Regards,
