Re: [wxhaskell-devel] Darcs patch: support for XRC based resources in wxHaskell

[Jeremy O'D. <jer...@gm...>]

Hi Shelarcy,

I'll try it on my Mac when I get home - could prove to be a
pre-processor difference between Visual Studio and GCC.

In the two cases given, I'd expect the BUILD_XRCGETCTRL_FN macro to
expand as follows:

Where _typ is Sizer
EWXWEXPORT(wxSizer*, wxXmlResource_GetSizer)(wxWindow* _win, wxString*
_str_id)
{
  return
  reinterpret_cast<wxSizer*>(_win->FindWindow(wxXmlResource::GetXRCID(*_str_id));
}

Where _typ is BoxSizer
EWXWEXPORT(wxBoxSizer*, wxXmlResource_GetBoxSizer)(wxWindow* _win,
wxString* _str_id)
{
  return
  reinterpret_cast<wxBoxSizer*>(_win->FindWindow(wxXmlResource::GetXRCID(*_str_id));
}

One thing to try: does adding a space after the paste tokens and before
the '*' tokens help? (i.e.

#define BUILD_XRCGETCTRL_FN(_typ)                                       
                     \
  EWXWEXPORT(wx##_typ## *, wxXmlResource_Get##_typ)(wxWindow* _win,
  wxString* _str_id)        \
  {                                                                     
                       \
  return reinterpret_cast<wx##_typ##
  *>(_win->FindWindow(wxXmlResource::GetXRCID(*_str_id))); \
  }

Alternatively, it's pretty easy to replace the auto-generated functions
with the manually created versions. If you find that the extra space
suggestion above does not work, I'll do a patch tomorrow with each of
the functions implemented in full.

Regards
Jeremy
