crt.d

Object-Oriented Programming With ANSI-C这本书中的源代码!找了很久

// new(Crt())
//	wraps a curses window, gate(crt, 0) produces events

// new(CLineOut(), y, x, len)
//	LineOut, located at y, x, with line length len

// new(CButton(), "text", y, x)
//	Button, located at y, x, sized for "text"

	void * window;		// curses WINDOW
	int rows;		// size
	int cols;

	void makeWindow (_self, int rows, int cols, int y, int x);
	void addStr(_self, int y, int x, const char * s);
	void crtBox(_self);
