When I traced source code of iPDF and tried to code a GTK app for iLiad, I found that screen refresh on iLiad is not in normal GTK way. iPDF use some function to write to framebuffer. (jharker in this thread will provide more info: http://forum.irexnet.com/viewtopic.php?t=1269
When I tried to find more info on framebuffer, I found that there is a DirectFB project, and GTK is also supported on DirectFB. (http://www.directfb.org/wiki/index.p...TK_on_DirectFB
Honestly, I am totally ignorant about DirectFB. But I wonder if it can be ported to iLiad. If it does, maybe we can get better performance.
