3067 NB: there used to be some code here which set the initial size of the
3068 window to the client size of the parent if no explicit size was
3069 specified. This was wrong because wxWidgets programs often assume
3070 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3071 it. To see why, you should understand that Windows sends WM_SIZE from
3072 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3073 from some base class ctor and so this WM_SIZE is not processed in the
3074 real class' OnSize() (because it's not fully constructed yet and the
3075 event goes to some base class OnSize() instead). So the WM_SIZE we
3076 rely on is the one sent when the parent frame resizes its children
3077 but here is the problem: if the child already has just the right
3078 size, nothing will happen as both wxWidgets and Windows check for
3079 this and ignore any attempts to change the window size to the size it
3080 already has - so no WM_SIZE would be sent.
