2984 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2985 it. To see why, you should understand that Windows sends WM_SIZE from
2986 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2987 from some base class ctor and so this WM_SIZE is not processed in the
2988 real class' OnSize() (because it's not fully constructed yet and the
2989 event goes to some base class OnSize() instead). So the WM_SIZE we
2990 rely on is the one sent when the parent frame resizes its children
2991 but here is the problem: if the child already has just the right
2992 size, nothing will happen as both wxWidgets and Windows check for
2993 this and ignore any attempts to change the window size to the size it
2994 already has - so no WM_SIZE would be sent.
