# screen log window
|
|
# =================
|
|
#
|
|
#
|
|
# simple use:
|
|
#
|
|
# foo = screen.window.new()
|
|
# foo.write("message in the middle of the screen");
|
|
#
|
|
#
|
|
# advanced use:
|
|
#
|
|
# bar = screen.window.new(nil, -100, 3, 10);
|
|
# bar.fg = [1, 1, 1, 1]; # choose white color
|
|
# bar.align = "left";
|
|
#
|
|
# bar.write("first line");
|
|
# bar.write("second line (red)", 1, 0, 0);

|
|
# x ... x coordinate
|
|
# y ... y coordinate
|
|
# positive coords position relative to the left/lower corner,
|
|
# negative coords from the right/upper corner, nil centers
|
|
# maxlines ... max number of displayed lines; if more are pushed into the
|
|
# screen, then the ones on top fall off
|
|
# autoscroll ... seconds that each line should be shown; can be less if
|
|
# a message falls off; if 0 then don't scroll at all
