3065 NB: there used to be some code here which set the initial size of the
3066 window to the client size of the parent if no explicit size was
3067 specified. This was wrong because wxWidgets programs often assume
3068 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3069 it. To see why, you should understand that Windows sends WM_SIZE from
3070 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3071 from some base class ctor and so this WM_SIZE is not processed in the
3072 real class' OnSize() (because it's not fully constructed yet and the
3073 event goes to some base class OnSize() instead). So the WM_SIZE we
3074 rely on is the one sent when the parent frame resizes its children
3075 but here is the problem: if the child already has just the right
3076 size, nothing will happen as both wxWidgets and Windows check for
3077 this and ignore any attempts to change the window size to the size it
3078 already has - so no WM_SIZE would be sent.
