Jean-Pierre & Other Developers,


It is my understanding that on newer versions of wxWidgets, we will not 
be able to pass wxString.c_str() to the Printf() function of wxString. 
And wxString.GetData() will not exist.


http://docs.wxwidgets.org/stable/wx_wxstring.html#wxstringcstr


I first discovered this when using wxWidgets 2.9, and this is why I 
wrote the GetChars( wxString ) function to hide this future migration 
problem.

Please let me know if I am wrong, otherwise please consider minimizing 
our pain in the future and look into our macros.h's GetChars() please.


(I do like the wxString.Printf() function. And this is no reason to 
stop using that.)


So according to my understanding, we are better writing:

wxString s;
wxString formatMe;

s.Printf( wxT("%s"), GetChars( formatMe ) );

than this:

s.Printf( wxT("%s"), formatMe.c_str() );


For 2.9 or 3.0 the c_str() will not work, at least that is my 
understanding based on a snapshot 5 months ago when I wrote GetChars().


Tootles,

Dick
