3432 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3433 it. To see why, you should understand that Windows sends WM_SIZE from
3434 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3435 from some base class ctor and so this WM_SIZE is not processed in the
3436 real class' OnSize() (because it's not fully constructed yet and the
3437 event goes to some base class OnSize() instead). So the WM_SIZE we
3438 rely on is the one sent when the parent frame resizes its children
3439 but here is the problem: if the child already has just the right
3440 size, nothing will happen as both wxWidgets and Windows check for
3441 this and ignore any attempts to change the window size to the size it
3442 already has - so no WM_SIZE would be sent.
