curses and python (linux, debian)

[Guido]

Hello

I'm new to python and i'm trying to write a script
that shows a menu.

Now, I have some troubles with curses.setsyx()

I do:

import curses

curses.setsyx(2, 20)
curses.putp("TEST TITLE")
curses.setsyx(25, 35)
curses.putp("TEST CENTER")
curses.setsyx(12, 35)
curses.putp("TEST CENTER")

but it just prints all the string after each other
at the first lines..

can anybody help me please?

thx!

Er, that's really the wrong way to do it. For one thing, curses.putp
doesn't do what you think you want it to do. Have a look at "Curses
Programming with Python":
http://www.amk.ca/python/howto/curses/

Something like this:

import curses

def main(stdscr):
stdscr.addstr(2, 20, "TEST TITLE")
stdscr.addstr(25,35, "TEST CENTER")
stdscr.addstr(12,35, "TEST CENTER")
while 1:
c = stdscr.getch()
if c == ord('q'):
return

curses.wrapper(main)

Don't you call initscr() first?

thx very much

very handy tutorial!

Now, i'm using DrPython, it looks fine, but i
can't debug my curses program

It gives an error with this message:
curses.wrapper returned ERR on curses.cbreak

if i run it with python, it works!

anybody?

I'm not familiar with DrPython, but it looks like a IDE. The console
widget it uses for the Python shell probably doesn't support enough to
be a 'real' terminal, so curses likely doesn't work in it. You'll have
to run it in a terminal program like xterm.

From the command line, right? There you go

well, I like a good editor, and DrPython seemed nice.

Do you have any other suggestions?

Otherwise I'll stay with the combo solution
