3168 NB: there used to be some code here which set the initial size of the
3169 window to the client size of the parent if no explicit size was
3170 specified. This was wrong because wxWidgets programs often assume
3171 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3172 it. To see why, you should understand that Windows sends WM_SIZE from
3173 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3174 from some base class ctor and so this WM_SIZE is not processed in the
3175 real class' OnSize() (because it's not fully constructed yet and the
3176 event goes to some base class OnSize() instead). So the WM_SIZE we
3177 rely on is the one sent when the parent frame resizes its children
3178 but here is the problem: if the child already has just the right
3179 size, nothing will happen as both wxWidgets and Windows check for
3180 this and ignore any attempts to change the window size to the size it
3181 already has - so no WM_SIZE would be sent.
3185 // we don't use CW_USEDEFAULT here for several reasons:
3187 // 1. it results in huge frames on modern screens (1000*800 is not
3188 // uncommon on my 1280*1024 screen) which is way too big for a half
3189 // empty frame of most of wxWidgets samples for example)
3191 // 2. it is buggy for frames with wxFRAME_TOOL_WINDOW style for which
3192 // the default is for whatever reason 8*8 which breaks client <->
3193 // window size calculations (it would be nice if it didn't, but it
3194 // does and the simplest way to fix it seemed to change the broken
3195 // default size anyhow)
3197 // 3. there is just no advantage in doing it: with x and y it is
3198 // possible that [future versions of] Windows position the new top
3199 // level window in some smart way which we can't do, but we can
3200 // guess a reasonably good size for a new window just as well
