Right that would have the same effect.

I would only expect the expand to be distributed evenly among 
children as, thats what GtkBox does ;-)

I'm not sure that having all the children stop expanding
when an expand child is added is any worse than having all
the extra column/row spacing suddenly disappear.

While I did add the "spreading" option to the wrap-box for
similar reasons... I'm not sure that there is an added benefit
to exporting more options here... unless it really makes something
possible which was not possible without the option.

Maybe a similar spreading option would be useful for the Grid ?
(i.e. decide whether Grid children EXPAND, or line up at the START
or END, or get spread EVEN)... not sure if it adds any real
value (alternatively you could add an empty widget that just 
expands and takes up space to the left or right of all children
to achieve the same START/END effect).
