looking for a replacement for directfb on embedded platforms - performance/memory


Hi All,

We primarily work on embedded platforms mostly based on ARM cores (running at 200/300 MHz, mostly without any hardware accelerators) that runs linux.

Our applications are generally rich in terms of gui content. We have veriety of windows with different logic etc. One example is a portable media player.

We use Directfb to create our GUI.

The problem that I face with Directfb based gui is:

The code becomes so huge to maintain.
Its difficult for another developer to read/review or reuse it for a different project.

Directfb is an abstration (feature rich) over linux frame buffer device, It was very useful since its release.
But I think its time that I should select another gui library which is more abstrated. (like abstration over Directfb etc).

The following are my goals:
1) less code size
2) avoid replication of logic
3) simple and easy to use/maintain.



Could you please point me to such an opensource gui library (which is proven on multiple embedded platforms), which can do this. provided it has acceptable memory foot print and performance on an embedded device.


Thanks in advance,
Ebin.
