3264 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3265 it. To see why, you should understand that Windows sends WM_SIZE from
3266 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3267 from some base class ctor and so this WM_SIZE is not processed in the
3268 real class' OnSize() (because it's not fully constructed yet and the
3269 event goes to some base class OnSize() instead). So the WM_SIZE we
3270 rely on is the one sent when the parent frame resizes its children
3271 but here is the problem: if the child already has just the right
3272 size, nothing will happen as both wxWidgets and Windows check for
3273 this and ignore any attempts to change the window size to the size it
3274 already has - so no WM_SIZE would be sent.
