Some further questions
Hi all
I am not sure whether following questions on embedded
GUI are off-topic here in this list, but they relly
have confused me for a long time:
AFASIK, there are many hot words in the field of
embedded GUI, such as: framebuffer, X Window,
DirectFB, SDL, QT/Embedded, GTK+. They really made me
confused.
In my view, "framebuffer" is a kind of Linux device
driver(I can find a charater device node /dev/fb0 on
my i386 box); And "X Window", "DirectFB" and "SDL"
seems resides on the same layer - they both provide
low level mechanism to access graphics subsystem and
user interaction. "GTK+" and "QT/Embedded" are widget
toolkits(libraries).
I'd really like to know am I right in understanding
these stuff? ANY hints would be highly appreciated.
Best regards,
Jarod Wang
