3029 NB: there used to be some code here which set the initial size of the
3030 window to the client size of the parent if no explicit size was
3031 specified. This was wrong because wxWidgets programs often assume
3032 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3033 it. To see why, you should understand that Windows sends WM_SIZE from
3034 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3035 from some base class ctor and so this WM_SIZE is not processed in the
3036 real class' OnSize() (because it's not fully constructed yet and the
3037 event goes to some base class OnSize() instead). So the WM_SIZE we
3038 rely on is the one sent when the parent frame resizes its children
3039 but here is the problem: if the child already has just the right
3040 size, nothing will happen as both wxWidgets and Windows check for
3041 this and ignore any attempts to change the window size to the size it
