3057 NB: there used to be some code here which set the initial size of the
3058 window to the client size of the parent if no explicit size was
3059 specified. This was wrong because wxWidgets programs often assume
3060 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3061 it. To see why, you should understand that Windows sends WM_SIZE from
3062 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3063 from some base class ctor and so this WM_SIZE is not processed in the
3064 real class' OnSize() (because it's not fully constructed yet and the
3065 event goes to some base class OnSize() instead). So the WM_SIZE we
3066 rely on is the one sent when the parent frame resizes its children
3067 but here is the problem: if the child already has just the right
3068 size, nothing will happen as both wxWidgets and Windows check for
3069 this and ignore any attempts to change the window size to the size it
3070 already has - so no WM_SIZE would be sent.
