一个小巧的嵌入式图形系统wGUI, 可以用VC编译

#include "wgui.h"
#include <iostream>

using namespace std;
using namespace wGui;

class CCalcApp : public CApplication
{
public:
	CCalcApp(int argc, char **argv) : CApplication(argc, argv) { }

	virtual void Init(void)
	{
		CApplication::Init();
		SetDefaultFontEngine(GetFontEngine("Vera.ttf"));
	}
};


int main(int argc, char **argv)
{
	int iExitCode = EXIT_FAILURE;
	try
	{
		CCalcApp CalcApp(argc, argv);
		CalcApp.Init();
		CalcApp.Exec();

		iExitCode = CalcApp.ExitCode();
	}
	catch (Wg_Ex_Base& e)
	{
		cerr << "Unhandled wGui exception : " << e.what() << endl;
		exit(EXIT_FAILURE);
	}
	catch (exception& e)
	{
		cerr << "Unhandled std exception : " << e.what() << endl;
		exit(EXIT_FAILURE);
	}
	catch (...)
	{
		cerr << "Unhandled exception." << endl;
		exit(EXIT_FAILURE);
	}
	exit (iExitCode);
}
