wxWidgets/samples/listctrl/listtest.cpp
Blake Eryx 65827a0572 Remove unnecessary c_str() calls from the samples 
Pass wxStrings directly to wxString::Format("%s") and similar
pseudo-vararg functions, there is no need for c_str() there since
wxWidgets 2.9.

Closes https://github.com/wxWidgets/wxWidgets/pull/1009
