[SOLVED] python + ncurses, scrollable window

boast · 2013-05-12 07:52:02

Say I have a huge text file and I want to put it in an ncurses pad so the user can scroll through it, how is it done?

I have something like

max_x = stdscr.getmaxyx()[1]
max_y = stdscr.getmaxyx()[0]
log_window = curses.newpad(max_y,max_x)

but I can't slam all the file lines in there because it is bigger than the newpad size.

if I do

log_window = curses.newpad(len(file_data),max_x)
log_window.refresh(window_position,0,4,0,max_y,max_x

I get

_curses.error: prefresh() returned ERR

Can't think if any way to get this done.

You can check out the code in the editor function of keepassc to see how we did it. So far we've only implemented vertical scrolling, not horizontal yet. We didn't use pads either...just fancy scrolling in the buffer.

If you want to load the whole file into a pad, then you could also create a fitting pad and then use a subpad which you will display in the console.
The refresh call seems to be fine. What is the value of window_position?
