3293 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3294 it. To see why, you should understand that Windows sends WM_SIZE from
3295 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3296 from some base class ctor and so this WM_SIZE is not processed in the
3297 real class' OnSize() (because it's not fully constructed yet and the
3298 event goes to some base class OnSize() instead). So the WM_SIZE we
3299 rely on is the one sent when the parent frame resizes its children
3300 but here is the problem: if the child already has just the right
3301 size, nothing will happen as both wxWidgets and Windows check for
3302 this and ignore any attempts to change the window size to the size it
3303 already has - so no WM_SIZE would be sent.
