3610 NB: there used to be some code here which set the initial size of the
3611 window to the client size of the parent if no explicit size was
3612 specified. This was wrong because wxWidgets programs often assume
3613 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3614 it. To see why, you should understand that Windows sends WM_SIZE from
3615 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3616 from some base class ctor and so this WM_SIZE is not processed in the
3617 real class' OnSize() (because it's not fully constructed yet and the
3618 event goes to some base class OnSize() instead). So the WM_SIZE we
3619 rely on is the one sent when the parent frame resizes its children
3620 but here is the problem: if the child already has just the right
3621 size, nothing will happen as both wxWidgets and Windows check for
