2909 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2910 it. To see why, you should understand that Windows sends WM_SIZE from
2911 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2912 from some base class ctor and so this WM_SIZE is not processed in the
2913 real class' OnSize() (because it's not fully constructed yet and the
2914 event goes to some base class OnSize() instead). So the WM_SIZE we
2915 rely on is the one sent when the parent frame resizes its children
2916 but here is the problem: if the child already has just the right
2917 size, nothing will happen as both wxWindows and Windows check for
2918 this and ignore any attempts to change the window size to the size it
2919 already has - so no WM_SIZE would be sent.
