3039 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3040 it. To see why, you should understand that Windows sends WM_SIZE from
3041 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3042 from some base class ctor and so this WM_SIZE is not processed in the
3043 real class' OnSize() (because it's not fully constructed yet and the
3044 event goes to some base class OnSize() instead). So the WM_SIZE we
3045 rely on is the one sent when the parent frame resizes its children
3046 but here is the problem: if the child already has just the right
3047 size, nothing will happen as both wxWidgets and Windows check for
3048 this and ignore any attempts to change the window size to the size it
3049 already has - so no WM_SIZE would be sent.
