3042 /*
3043 NB: there used to be some code here which set the initial size of the
3044 window to the client size of the parent if no explicit size was
3045 specified. This was wrong because wxWidgets programs often assume
3046 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3047 it. To see why, you should understand that Windows sends WM_SIZE from
3048 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3049 from some base class ctor and so this WM_SIZE is not processed in the
3050 real class' OnSize() (because it's not fully constructed yet and the
3051 event goes to some base class OnSize() instead). So the WM_SIZE we
3052 rely on is the one sent when the parent frame resizes its children
3053 but here is the problem: if the child already has just the right
3054 size, nothing will happen as both wxWidgets and Windows check for
3055 this and ignore any attempts to change the window size to the size it
3056 already has - so no WM_SIZE would be sent.

3066 // 2. it is buggy for frames with wxFRAME_TOOL_WINDOW style for which
