[Tutor] curses.wrapper() question

[Alex from Caustic Creations]

Hello,

I'm trying to learn python because I would like to create a simple cash
register application using curses. I read the curses howto and the
reference manual and both refer to the curses.wrapper function. The
advantages of using the wrapper are significant, yet I can't seem to
call it up properly.

I've included my "test.py" program - a compilation of all of the
statements in the curses howto so I could see and play around with their
effects. If anyone can find the time, could someone alter this little
demo program using the curses wrapper to illustrate its correct use?

Thanks so much in advance,

Alex

import curses

	begin_x = 20 ; begin_y = 7
	height = 5 ; width = 40
	win = curses.newwin(height, width, begin_y, begin_x)
	return

		try: pad.addch(y,x, ord('a') + (x*x+y*y) % 26)
		except curses.error: pass

pad.refresh(0,0, 5,5, 20,75)

# Display "Current Mode" line att he top of the screen

stdscr.addstr(0, 0, "Current mode: Typing mode",
	      curses.A_BOLD)
stdscr.refresh()

# Coloured text test

stdscr.refresh()
curses.init_pair(1, curses.COLOR_GREEN, curses.COLOR_BLACK)
stdscr.addstr( 0,80, "Pretty text", curses.color_pair(1) )
stdscr.refresh()

# Keyboard input test

while 1:
	c = stdscr.getch()
	if c == ord('p'): stdscr.addstr( 2,60, "You typed the letter p",
curses.color_pair(1) )
	elif c == ord('q'): break
	elif c == curses.KEY_HOME: x=y=0

# Ending curses politely

curses.nocbreak(); stdscr.keypad(0); curses.echo()
curses.endwin()
