3036 it. To see why, you should understand that Windows sends WM_SIZE from
3037 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3038 from some base class ctor and so this WM_SIZE is not processed in the
3039 real class' OnSize() (because it's not fully constructed yet and the
3040 event goes to some base class OnSize() instead). So the WM_SIZE we
3041 rely on is the one sent when the parent frame resizes its children
3042 but here is the problem: if the child already has just the right
3043 size, nothing will happen as both wxWidgets and Windows check for
3044 this and ignore any attempts to change the window size to the size it
3045 already has - so no WM_SIZE would be sent.
