3255 NB: there used to be some code here which set the initial size of the
3256 window to the client size of the parent if no explicit size was
3257 specified. This was wrong because wxWidgets programs often assume
3258 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3259 it. To see why, you should understand that Windows sends WM_SIZE from
3260 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3261 from some base class ctor and so this WM_SIZE is not processed in the
3262 real class' OnSize() (because it's not fully constructed yet and the
3263 event goes to some base class OnSize() instead). So the WM_SIZE we
3264 rely on is the one sent when the parent frame resizes its children
3265 but here is the problem: if the child already has just the right
3266 size, nothing will happen as both wxWidgets and Windows check for
3267 this and ignore any attempts to change the window size to the size it
3268 already has - so no WM_SIZE would be sent.
3272 // we don't use CW_USEDEFAULT here for several reasons:
3274 // 1. it results in huge frames on modern screens (1000*800 is not
3275 // uncommon on my 1280*1024 screen) which is way too big for a half
3276 // empty frame of most of wxWidgets samples for example)
3278 // 2. it is buggy for frames with wxFRAME_TOOL_WINDOW style for which
3279 // the default is for whatever reason 8*8 which breaks client <->
3280 // window size calculations (it would be nice if it didn't, but it
3281 // does and the simplest way to fix it seemed to change the broken
3282 // default size anyhow)
3284 // 3. there is just no advantage in doing it: with x and y it is
3285 // possible that [future versions of] Windows position the new top
3286 // level window in some smart way which we can't do, but we can
