2948           specified. This was wrong because wxWidgets programs often assume
2949           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2950           it. To see why, you should understand that Windows sends WM_SIZE from
2951           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2952           from some base class ctor and so this WM_SIZE is not processed in the
2953           real class' OnSize() (because it's not fully constructed yet and the
2954           event goes to some base class OnSize() instead). So the WM_SIZE we
2955           rely on is the one sent when the parent frame resizes its children
2956           but here is the problem: if the child already has just the right
2957           size, nothing will happen as both wxWidgets and Windows check for
2958           this and ignore any attempts to change the window size to the size it
2959           already has - so no WM_SIZE would be sent.
