qt- mouse-cursor problem

[magicsix]

Hi everyone,
my mouse can work in my qt application(as (1)),but the cursor cannot move,it is always
in the center of the screen.

(1)i wrote a small program that there is a button in the window,if i move the mouse,
the button can change it's position,and this can work.



I used the following config when building
-qt-mouse-pc
QWS_MOUSE_PROTO="intelliMouse:/dev/mouse0"



my english is so bad,i hope you can understand me,thanks.
