2996 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2997 it. To see why, you should understand that Windows sends WM_SIZE from
2998 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2999 from some base class ctor and so this WM_SIZE is not processed in the
3000 real class' OnSize() (because it's not fully constructed yet and the
3001 event goes to some base class OnSize() instead). So the WM_SIZE we
3002 rely on is the one sent when the parent frame resizes its children
3003 but here is the problem: if the child already has just the right
3004 size, nothing will happen as both wxWidgets and Windows check for
3005 this and ignore any attempts to change the window size to the size it
3006 already has - so no WM_SIZE would be sent.
