3279 NB: there used to be some code here which set the initial size of the
3280 window to the client size of the parent if no explicit size was
3281 specified. This was wrong because wxWidgets programs often assume
3282 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3283 it. To see why, you should understand that Windows sends WM_SIZE from
3284 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3285 from some base class ctor and so this WM_SIZE is not processed in the
3286 real class' OnSize() (because it's not fully constructed yet and the
3287 event goes to some base class OnSize() instead). So the WM_SIZE we
3288 rely on is the one sent when the parent frame resizes its children
3289 but here is the problem: if the child already has just the right
3290 size, nothing will happen as both wxWidgets and Windows check for
3291 this and ignore any attempts to change the window size to the size it
3292 already has - so no WM_SIZE would be sent.
3296 // we don't use CW_USEDEFAULT here for several reasons:
3298 // 1. it results in huge frames on modern screens (1000*800 is not
3299 // uncommon on my 1280*1024 screen) which is way too big for a half
3300 // empty frame of most of wxWidgets samples for example)
3302 // 2. it is buggy for frames with wxFRAME_TOOL_WINDOW style for which
3303 // the default is for whatever reason 8*8 which breaks client <->
