how to use Qcursor to move the mouse cursor

[jack_shen]

hi,

i am new to qt.
here is my problem:
i want to move the mouse cursor in a QWebView widget. so i use Qcursor::setPos() to change the postion of the mouse cursor. and setPos() is called in the event() function ( i reimplement it ). but when it runs, the mouse cursor dosent move at all. but when setCursor(Qt::CrossCursor) is called, the shape of the cursor does change, and position returned from pos() alse changed. but the cursor doesnt move at all
i dont know if it is nessecery to call other flush function to reflush the screen.

thks
