ChunLiang,
Thanks for your precious reply.
Yes, I’m a Chinese.how do you know :)? I’m in Shenzhen ,where are u ?
Now I ‘m evaluating GUI system for a IPTV project . I notice Directfb have
a great feature in graphics and hardware acceleration.and I notice LiTE,and
GTK-directfb, both of them can work together. I have tested them in vmware.
But I still have some questions
1) Is them any limitations in simple window manager? If yes, can gtk
–directfb make up these limitations . it seems gtk-directfb use same window
manager with directfb,doesn’t it?
2) Is it stable in arm with mmu and no mmu, does it support static link-one
application core and static link-muti application cores? For in
uclinux,dynamic link is not so popular
3) Is Xdirectfb suitable for embedded devices, how big?
There are several features we ‘re considering in GUI
1) be lightweight ,stable and with expansibility,
2) muti-application core and single application core at same time
3) static link and dynamic link
4) good graphics capacity, easy to make colorful buttons, regular shapes
window with unite theme. Our hardware supports muti-layer, and one
alphablending channel
5) Easy to provide backend for Java virtual machine
6) It’s better to support SDL
There are several solution for GUI
1directfb→lite -→gtk
2 TinyX→with fltk,→gtk
3 nanoX→fltk
4 xdirectfb
Can TinyX or nanoX manage muti-layer in framebuffer?
Can you give me some suggestions
Thank again for your help
Best wishes,
Jiao

Hi!
Welcome to DirectFB world!:)
As I know, DirectFB focuses on low level graphics operations, such as blending
image, drawing rectangle, etc. A very important feature of DirectFB is H/W
acceleration. It have a very simple window manager and you can do basic window
management. But as X window system does, it lacks GUI ToolKit. That means it
have no button, label, menu, etc. But many upper projects, such as GTK, QT,
XDirectFB, ..., work very well on DirectFB. If you need a very light GUI
system, you can take a look at LiTE.
Wish you enjoy DirectFB!:)
BTW: Are you a Chinese?:)

I'm glad to find DirectFB, it can manage serval display layer. Now I'm
developing an IPTV STB box, doesn't it enough to fit the requirements as a
GUI system, is it mature?
