curses.panel

[Oleg Broytmann]

Hello!

   Is there anyone who program with curses these days? These days are full
of GUI and CGIs, but as they included curses.panel as a new module in
curses, I think there are curses users. I want to learn curses.
   Yes, curses. If I would want to write a GUI - I'd do it with graphical
toolkit, probably wxWindows. But now I want to learn curses.
   I am newbie in curses programming. I never wrote curses programs in C,
and I want to learn curses by programming in Python.

   Ok, I wrote few very simple program - they work. So I started to write
more complex program... and stumbled upon panels. I cannot use panels -
cannot change stack order, e.g. Can anyone help?


from time import sleep
import curses, curses.panel


def make_panel(stdscr, h,l, y,x, str):
   win = stdscr.subwin(h,l, y,x)
   win.erase()
   win.box()
   win.addstr(2, 2, str)

   panel = curses.panel.new_panel(win)
   return win, panel


def test(stdscr):
   curses.curs_set(0)
   stdscr.box()
   stdscr.addstr(2, 2, "panels everywhere")
   win1, panel1 = make_panel(stdscr, 10,12, 5,5, "Panel 1")
   win2, panel2 = make_panel(stdscr, 10,12, 8,8, "Panel 2")
   stdscr.refresh()
   sleep(1)

   panel1.top(); curses.panel.update_panels()
   stdscr.refresh()
   sleep(1) # This DOES NOT work! panel1 is still bottom panel :(((

   for i in range(50): # This works... partially... panel1 is not updated :(((
      panel2.move(8, 8+i)
      stdscr.refresh()
      sleep(0.1)

   sleep(1)


if __name__ == '__main__':
   curses.wrapper(test)

           Programmers don't die, they just GOSUB without RETURN.
