3034 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3035 from some base class ctor and so this WM_SIZE is not processed in the
3036 real class' OnSize() (because it's not fully constructed yet and the
3037 event goes to some base class OnSize() instead). So the WM_SIZE we
3038 rely on is the one sent when the parent frame resizes its children
3039 but here is the problem: if the child already has just the right
3040 size, nothing will happen as both wxWidgets and Windows check for
3041 this and ignore any attempts to change the window size to the size it
3042 already has - so no WM_SIZE would be sent.
