3097 NB: there used to be some code here which set the initial size of the
3098 window to the client size of the parent if no explicit size was
3099 specified. This was wrong because wxWidgets programs often assume
3100 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3101 it. To see why, you should understand that Windows sends WM_SIZE from
3102 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3103 from some base class ctor and so this WM_SIZE is not processed in the
3104 real class' OnSize() (because it's not fully constructed yet and the
3105 event goes to some base class OnSize() instead). So the WM_SIZE we
3106 rely on is the one sent when the parent frame resizes its children
3107 but here is the problem: if the child already has just the right
3108 size, nothing will happen as both wxWidgets and Windows check for
3109 this and ignore any attempts to change the window size to the size it
3110 already has - so no WM_SIZE would be sent.
