Hi,
Thanks for the response.

However, while changing things around, I discovered what is causing
the error: the coordinate 30, 10 is off my screen. When I change the
y, x coordinates to 5, 10, then the program executes as it should.
However, now I am having a problem trying to set the color of the text
that is output:
import curses
def my_program(screen):
while True:
ch = screen.getch()
if ch == ord("q"):
break
if ch <= 255:
output = "*%s*" % chr(ch)
screen.addstr(5, 5, output, curses.COLOR_RED)
screen.refresh()
curses.wrapper(my_program)
A strange thing is happening. The integer value of the constant
curses.COLOR_RED is 1, and when I type in a character, 1 is getting
added to the character's ascii code. For instance, if I type in an
'h', then an 'i' displays on the screen--and in white, not red.
I did some testing and has_colors() returns True, but I still can't
get the curses output to show up in red. The tutorial:
Curses Programming with Python
A.M. Kuchling, Eric S. Raymond
says:
To use color, you must call the start_color() function soon after
calling initscr(), to initialize the default color set (the
curses.wrapper.wrapper() function does this automatically). Once
that's done, the has_colors() function returns TRUE if the terminal in
use can actually display color.
Another thing that is strange: that paragraph uses the syntax
curses.wrapper.wrapper(). And the docs say this:
--------
6.17 curses.wrapper -- Terminal handler for curses programs
New in version 1.6.
This module supplies one function, wrapper()...
--------
which implies that I should be using the syntax
curses.wrapper.wrapper() in my code. But I get an error when I try
it:
Traceback (most recent call last):
File "2pythontest.py", line 16, in ?
curses.wrapper.wrapper(my_program)
AttributeError: 'function' object has no attribute 'wrapper'
I get the same error if add the import statement:
import curses.wrapper
I'm using an intel mac if that makes any difference.
