(C++) StringGridToVector

VCL code snippet to convert a VCL TStringGrid to a 2D std::vector.

#include <cassert> #include <string> #include <vector> #include <boost/lexical_cast.hpp> #include <vcl.h> //From http://www.richelbilderbeek.nl/CppStringGridToVector.htm template <class T> const std::vector<std::vector<T> > StringGridToVector(const TStringGrid * const stringGrid) { assert(stringGrid!=0 && "StringGrid must not be NULL"); const int height = stringGrid->RowCount; const int width = stringGrid->ColCount; std::vector<std::vector<T> > v(height, std::vector<T>(width)); for (int y=0; y!=height; ++y) { assert(y >=0); assert(y < static_cast<int>(v.size()) ); std::vector<T>& line = v[y]; //Don't have the guts to do a line-access on a TStringGrid... for (int x=0; x!=width; ++x) { assert(x >=0); assert(x < static_cast<int>(line.size()) ); //const_cast because the VCL is not const-correct. Grumble, grumble... const std::string s = (const_cast<TStringGrid*>(stringGrid)->Cells[x][y]).c_str(); const T t = boost::lexical_cast<T>(s); vLine[x] = t; } } return v; }
