Subject: 386 curses

386 curses gives the window structure as follows.

This is new code and will contain some bugs.

typedef unsigned short  chtype;

struct _win_st {
	short   _cury, _curx;
	short   _maxy, _maxx;
	short   _begy, _begx;
	short   _flags;
	chtype  _attrs;
	bool    _clear;
	bool    _leave;
	bool    _scroll;
	bool    _idlok;
	bool    _use_keypad;    /* 0=no, 1=yes, 2=yes/timeout */
	bool    _use_meta;      /* T=use the meta key */
	bool    _nodelay;       /* T=don't wait for tty input */
	chtype  **_line;
	short   *_firstchar;    /* First changed character in the line */
	short   *_lastchar;     /* Last changed character in the line */
	short   *_numchngd;     /* Number of changes made in the line */
	short	_regtop;	/* Top and bottom of scrolling region */
	short	_regbottom;
};


Note for the mvwin() function. Only use this for newwin() windows not
subwin() windows as the latter point to the parent window. Moving a
window does not erase the previous copy, to do this touchwin() and
refresh() the underlaying window. Note that touchwin() refresh() is
likely to erase other overlaying windows which must be touchwin()ed and
refresh()ed.

If you are going to be doing much of this it is best to keep a tree
showing display structure. When a window is moved, touchwin and refresh
the window under the old location. When a window is touchwin() and
refresh()ed, touchwin() and refresh() any windows over it.
