3427 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3428 it. To see why, you should understand that Windows sends WM_SIZE from
3429 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3430 from some base class ctor and so this WM_SIZE is not processed in the
3431 real class' OnSize() (because it's not fully constructed yet and the
3432 event goes to some base class OnSize() instead). So the WM_SIZE we
3433 rely on is the one sent when the parent frame resizes its children
3434 but here is the problem: if the child already has just the right
3435 size, nothing will happen as both wxWidgets and Windows check for
3436 this and ignore any attempts to change the window size to the size it
3437 already has - so no WM_SIZE would be sent.
