3277 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3278 it. To see why, you should understand that Windows sends WM_SIZE from
3279 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3280 from some base class ctor and so this WM_SIZE is not processed in the
3281 real class' OnSize() (because it's not fully constructed yet and the
3282 event goes to some base class OnSize() instead). So the WM_SIZE we
3283 rely on is the one sent when the parent frame resizes its children
3284 but here is the problem: if the child already has just the right
3285 size, nothing will happen as both wxWidgets and Windows check for
3286 this and ignore any attempts to change the window size to the size it
3287 already has - so no WM_SIZE would be sent.
