curses: how to find the height of written text area

Question

I created a pad in curses then I filled it with a bunch of text. the height of the pad is constant, however, I would like to know how many lines there are in the written part of the pad or the height of it.

rows, cols = std.getmaxyx()
text_win = cur.newpad(rows*3, cols)
text_win.addstr("some stuff")

Answer 1

You can do this by inspecting the result from getyx:

rows, cols = std.getmaxyx()
text_win = cur.newpad(rows*3, cols)
text_win.addstr("some stuff")
cury, curx = text_win.getyx()
used_rows = cury + (1 if curx == 0 else 0)

Since the addstr started at the origin, you don't need to call getyx twice. The conditional expression accounts for line-wrapping.
