+ You don't have to raise an exception.  I sometimes have controls about
+ without parents.  Of course they are not visible, I set the
+ parent when and
+ where I want them to appear.
+
+ I also often change the parent during runtime to make controls appear
+ somewhere else (hence need for destroywnd and createwnd)

You only get an exeption if you want the handle of your control when it has
no parent. And as far as I can recall in Lazarus it is the same.
As long as you don't need the handle (IE, the physical component) it is OK
to have no parent.
