3068 NB: there used to be some code here which set the initial size of the
3069 window to the client size of the parent if no explicit size was
3070 specified. This was wrong because wxWidgets programs often assume
3071 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3072 it. To see why, you should understand that Windows sends WM_SIZE from
3073 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3074 from some base class ctor and so this WM_SIZE is not processed in the
3075 real class' OnSize() (because it's not fully constructed yet and the
3076 event goes to some base class OnSize() instead). So the WM_SIZE we
3077 rely on is the one sent when the parent frame resizes its children
3078 but here is the problem: if the child already has just the right
3079 size, nothing will happen as both wxWidgets and Windows check for
3080 this and ignore any attempts to change the window size to the size it
3081 already has - so no WM_SIZE would be sent.
