From curses docs:
When you call a method to display or erase text, the effect doesn’t immediately show up on the display. ...
Accordingly, curses requires that you explicitly tell it to redraw windows, using the refresh() method of window objects. ...
You need screen.refresh()
and box1.refresh()
in correct order.
Working example
#!/usr/bin/env python
import curses
screen = curses.initscr()
try:
screen.border(0)
box1 = curses.newwin(20, 20, 5, 5)
box1.box()
screen.refresh()
box1.refresh()
screen.getch()
finally:
curses.endwin()
or
#!/usr/bin/env python
import curses
screen = curses.initscr()
try:
screen.border(0)
screen.refresh()
box1 = curses.newwin(20, 20, 5, 5)
box1.box()
box1.refresh()
screen.getch()
finally:
curses.endwin()
You can use immedok(True)
to automatically refresh window
#!/usr/bin/env python
import curses
screen = curses.initscr()
screen.immedok(True)
try:
screen.border(0)
box1 = curses.newwin(20, 20, 5, 5)
box1.immedok(True)
box1.box()
box1.addstr("Hello World of Curses!")
screen.getch()
finally:
curses.endwin()
