how to bind the scrollbar with viewport widget( urgent )

[Liu Neo-W4135C <W4135C motorola com>]

Title: Message

Expertises,

 

below is the snapshot of my code. i modified it from ../examples/scrolledwinow/. what i did is use a vbox which contains a button and a table as viewport. unfortunely, i couldn't make scrollbar work when move focus with arrow keys. i have tried gkt_scrolled_window_setv/hadjustment and gtk_viewport_setv/hadjustment and it seems not work. did i miss anything?

 

i really need your valuable and quickly help, so any suggestion will be grealy appreciated.

 

thanks in advance and best regards,

 

Liu, Nian
