wxString::Format and %

1.Formatting double with wxString::Format

Hi,

my program is compiled with MinGW on XP with wxWidgets-2.8.8.

Using wxString::Format("<%010.2f>", 3.14) I get the result
"<      3.14>" (padded with blanks).
When I use sprintf(buf, "<%010.2f>", 3.14) instead, then I get the
correct result "<0000003.14>".

Is this a bug in wxString?

2.wxString.Format()

3.[2.5.3] wxString::Format and unicode

Hi:

wxString::Format("Text: %s", bla)
doesn't work with an unicode build. It does not compile. I know this is 
to be expected.

However, these alternatives also do not work:

wxString::Format(_("Text: %s"), bla)
wxString::Format(wxTRANSLATE("Text: %s"), bla)
wxString::Format(_T("Text: %s"), bla)
wxString::Format(wxT("Text: %s"), bla)

The program compiles, but then it hangs on that line. The only way I 
found to make it work is to use:

_("Text: ") + wxString(bla, *wxConvCurrent)

I'm not claiming that this is an error. I actually think it is not. I 
just want to suggest that the docs and the examples on 
wxString::Format() should be updated. And perhaps a way should be found 
to prevent the program to hang.

Also note that wxString::Format(_("Text: %d"), number) works fine.

Here is a code that illustrates what I'm saying. Uncomment the line 
after
// this doesn't work
and the program hangs, although it compiles fine:

///////////////////////////////////////////

#include <wx/wx.h>

class MyApp: public wxApp {
   virtual bool OnInit();
};

IMPLEMENT_APP(MyApp)

bool MyApp::OnInit() {

   wxString msg = _("A number: ");

   int number = 33;
   // this works:
   msg += wxString::Format(_("decimal: %d, "), number);

   char *text = "33";
   // this doesn't work:
   //  msg += wxString::Format(_("string: %s."), text);
   // but this does:
   msg += _("string: ") + wxString(text, *wxConvCurrent) + _(".");


   wxMessageBox(msg, _("wxString::Format() with Unicode"), wxOK | 
wxICON_ERROR);
   return false;

}

/////////////////////////////////////

Just dump these lines into a file and compile.


Thanks


Paulo

4.wxString, Format etc.

Hi folks,

what's the rationale behind wxString wrt. to converting to/from char *
etc.? Is there any at all? Why doesn't wxString::Format understand
wxStrings?

One of the things I want to do is use wxString::Format with wxStrings.
Seems this hasn't been anticipated. Now I've tried the various
conversion functions (c_str(), char_str(), fn_str(), mb_str(),
wchar_str(), wc_str(), To8BitData()) and only c_str() seems to work,
however, the documentation says that it'll no longer work with wxWidgets 3.
What am I supposed to use then? Another thing is pathnames; I'm using
char_str() since fn_str() (which, according to the documentation, is the
proper thing to use, doesn't work.)
What's the canonical way to get anything useful out of a wxString?
Portably and without having to write special code for each combination
of OS/char width?

I'm currently using wxGTK 2.8.7 / Unicode but it should work on all
platforms (I don't care for ANSI builds).
