3069 NB: there used to be some code here which set the initial size of the
3070 window to the client size of the parent if no explicit size was
3071 specified. This was wrong because wxWidgets programs often assume
3072 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3073 it. To see why, you should understand that Windows sends WM_SIZE from
3074 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3075 from some base class ctor and so this WM_SIZE is not processed in the
3076 real class' OnSize() (because it's not fully constructed yet and the
3077 event goes to some base class OnSize() instead). So the WM_SIZE we
3078 rely on is the one sent when the parent frame resizes its children
3079 but here is the problem: if the child already has just the right
3080 size, nothing will happen as both wxWidgets and Windows check for
3081 this and ignore any attempts to change the window size to the size it
3082 already has - so no WM_SIZE would be sent.
