2997 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2998 it. To see why, you should understand that Windows sends WM_SIZE from
2999 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3000 from some base class ctor and so this WM_SIZE is not processed in the
3001 real class' OnSize() (because it's not fully constructed yet and the
3002 event goes to some base class OnSize() instead). So the WM_SIZE we
3003 rely on is the one sent when the parent frame resizes its children
3004 but here is the problem: if the child already has just the right
3005 size, nothing will happen as both wxWidgets and Windows check for
3006 this and ignore any attempts to change the window size to the size it
3007 already has - so no WM_SIZE would be sent.
