3037 it. To see why, you should understand that Windows sends WM_SIZE from
3038 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3039 from some base class ctor and so this WM_SIZE is not processed in the
3040 real class' OnSize() (because it's not fully constructed yet and the
3041 event goes to some base class OnSize() instead). So the WM_SIZE we
3042 rely on is the one sent when the parent frame resizes its children
3043 but here is the problem: if the child already has just the right
3044 size, nothing will happen as both wxWidgets and Windows check for
3045 this and ignore any attempts to change the window size to the size it
3046 already has - so no WM_SIZE would be sent.
