Curses sorely lacking an event loop?

    Is curses really lacking an event loop? Do I have to write my own? I
    infer from the docs that this is the case. For example, I want the
    screen to be updated with resize but I find myself waiting for getch()
    if I want user input, and so the screen must remain ugly until the user
    presses a key. What am I missing?

    Also, does anyone have boilerplate for handling mouse events? getmouse()
    returns an "ERR" of no particular description and also appears to
    require a preceding getch() and hence does not seem to be wired at all
    for clicks, although allusion to clicks is found in the descriptions for
    mouseinterval() and mousemask().

    Here is the error message for getmouse() in case anyone wants details:
    "_curses.error: getmouse() returned ERR". This is much less informative
    than one might hope.

    Thanks in advance for any help.

  2. I'm not a curses expert, but I can answer this part. When the screen
    is resized, SIGWINCH is sent to the process. You can use the normal
    signal handling apparatus to install a handler that updates the screen
    when that signal arrives.
