about childrenRect in workspace

[showhand]

I have a question about childrenRect in workspace:
I write some code :
QWidget *activeForm;
activeForm=workspace->activeWindow();
QRect rect;
rect=activeForm->geometry();
int x,y;
x=rect.x();
y=rect.y();
Although I move the activeForm, the activeForm's rect is a constant.
I don't know the reason. Can anybody give me a good idea .Thanks!
