2839 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2840 it. To see why, you should understand that Windows sends WM_SIZE from
2841 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2842 from some base class ctor and so this WM_SIZE is not processed in the
2843 real class' OnSize() (because it's not fully constructed yet and the
2844 event goes to some base class OnSize() instead). So the WM_SIZE we
2845 rely on is the one sent when the parent frame resizes its children
2846 but here is the problem: if the child already has just the right
2847 size, nothing will happen as both wxWindows and Windows check for
2848 this and ignore any attempts to change the window size to the size it
2849 already has - so no WM_SIZE would be sent.
