I'm working on python curses and I have an initial window with initscr(). Then I create several new windows to overlap it, I want to know if I can delete these windows and restore the standard screen without having to refill it. Is there a way? Could someone tell me the difference between a window, subwindow, pad and sub pad.
I have this code:
stdscr = curses.initscr()
####Then I fill it with random letters
stdscr.refresh()
newwin=curses.newwin(10,20,5,5)
newwin.touchwin()
newwin.refresh()
####I want to delete newwin here so that if I write stdscr.refresh() newwin won't appear
stdscr.touchwin()
stdscr.refresh()
####And here it should appear as if no window was created.
To clear characters until the end of the line, use clrtoeol(), To clear characters until the end of the window, use clrtobot().
The Windows version of Python doesn't include the curses module. A ported version called UniCurses is available.
The curses package comes with the Python standard library. In Linux and Mac, the curses dependencies should already be installed so there is no extra steps needed. On Windows, you need to install one special Python package, windows-curses available on PyPI to add support.
This, e.g, should work:
import curses
def fillwin(w, c):
y, x = w.getmaxyx()
s = c * (x - 1)
for l in range(y):
w.addstr(l, 0, s)
def main(stdscr):
fillwin(stdscr, 'S')
stdscr.refresh()
stdscr.getch()
newwin=curses.newwin(10,20,5,5)
fillwin(newwin, 'w')
newwin.touchwin()
newwin.refresh()
newwin.getch()
del newwin
stdscr.touchwin()
stdscr.refresh()
stdscr.getch()
curses.wrapper(main)
This fills the terminal with 'S'; at any keystoke, it fills the window with 'w'; at the next keystroke, it removes the window and show the stdscr again, so it's again all-'S'; at the next keystroke, the script ends and the terminal goes back to normal. Isn't this working for you? Or do you actually want something different...?
