This question seems common so I thought I'd write an article. Note that sometimes there may be more than one possible solutions, so don't forget to check the docs.
Literals
A literal is a string written in code with 'quotes around it'. A literal is not a wxString, and (in wxWidgets 2.8) will not be implicitly converted to one. This means that you can never pass in a raw literal into a wxWidget function or method (unless you don't care about your app not building with Unicode-enabled wxWidgets builds)
Instead, wxWidgets (prior to wxWidgets 3.0) requires you to use one of these macros to turn literals into wxString-compatible characters:
Rather than being a nuisance, the _(), wxT(), and _T() macros take care of some unicode issues.
Apr 30, 2011 written in MFC, all will share a very common, core subset of the. Framework, same would be true for wxWidget apps. These areas could very. Well be documented. I.e basic class hierarchy, persisting object, app/doc/view model, message/event maps, drawing, threading, just to new a few common areas.

I.e basic class hierarchy, persisting object, app/doc/view model, message/event maps, drawing, threading, just to new a few common areas. Set up your interface from scratch using wxWidgets (especially wxDesigner or DialogBlocks- it'll save you a lot of time) and when you have a shell prepared, you can start 'pouring in' code from the MFC app, with appropriate modifications. This is the approach I have used, and I found it very satisfactory.
char* to wxString
Note that in wxWidgets 3.0, it just works to pass a char array where a wxString parameter is expected, the conversion will be automatic and implicit, using the current locale encoding. So even in wx 3.0, the snippets presented below still make sense when you don't want to be at the mercy of the current locale encoding.
wxString to char*
mb_str() returns a temporary pointer; if you need the output for more than one function call (as is the case above), you can store the char buffer for a little while :
And if you really need to copy it in to char* (but why would you? ;) :
You can also use ToUTF8(), since which encoding you get is clearer than with mb_str()
From const char* to char*:
Variadic functions (like printf) won't work with mb_str(), but this will work:
Alternatively, use the method recommended in Potential Unicode Pitfalls:
wchar_t* to wxString
wxString to wchar_t*
See the following methods in the docs :
wxString to TCHAR
int to wxString
or
float to wxString
or
wxString to integer number
or
wxString to floating-point number
std::string to wxString
Starting from wxWidgets 3.0, you may also use the appropriate constructor
wxString to std::string
wxWidgets 2.8 :
Under wxWidgets 3.0, you may use
std::wstring to wxString
Starting from wxWidgets 3.0, you may use the appropriate constructor
wxString to std::wstring
Under wxWidgets 3.0, you may use
This is a small taste of some of the applications built with wxWidgets.
