Resizing dialog with form layout

[elizabeth.h1]

Hello

I have a dialog in which I have applied form layout as
top level layout.
Here is the structure of the dialog :

label horizontal layout
label lineEdit

in the horizontal layout I have two lineEdits.

When I resize the dialog only the lineEdit which is not in the horizontal layout is streched , and the lineEdits which are in the
horizontal layout are not streched.

I have applied to all my edit boxes size policies equal to (Expanding,Expanding,0,1) .
