C++ (Cpp) SetEquationText Examples

Example #1

File: LT_Graph.cpp Project: vectorstorm/vectorstorm-testbeds

void
ltGraph::SetResponseCurve( ltResponseCurve *curve )
{
	m_curve = curve;

	SetCurveName( curve->GetName() );
	SetEquationText( curve->GetEquationText() );
}

Example #2

File: MainDlg.cpp Project: alexey-malov/ood

void CMainDlg::UpdateEquation()
{
	auto solution = m_solver.GetEquationRoots();
	struct SolutionPrinter : boost::static_visitor<void>
	{
		CMainDlg & self;
		SolutionPrinter(CMainDlg &self)
			:self(self)
		{
		}
		void operator()(NoRealRoots)
		{
			self.SetSolutionText(L"No real roots");
		}
		void operator()(InfiniteNumberOfRoots)
		{
			self.SetSolutionText(L"Infinite number of roots");
		}
		void operator()(double root)
		{
			self.SetSolutionText((boost::wformat(L"One root: %1%") % root).str());
		}
		void operator()(const std::pair<double, double> & roots)
		{
			self.SetSolutionText((boost::wformat(L"Two roots: %1% and %2%") % roots.first % roots.second).str());
		}
	};

	SolutionPrinter printer(*this);
	solution.apply_visitor(printer);

	auto ToSignedString = [](double value) {
		std::wostringstream strm;
		strm << std::abs(value);

		return ((value < 0) ? L"- " : L"+ ") + strm.str();
	};

	SetEquationText((boost::wformat(L"%1%x\u00b2 %2%x %3% = 0") % m_solver.GetQuadraticCoeff() % ToSignedString(m_solver.GetLinearCoeff()) % ToSignedString(m_solver.GetConstantCoeff())).str());
