Mouse movement events in NCurses

由 浪子不回头ぞ 提交于 2019-12-17 16:28:01
问题 I wonder if there is such a thing as mouse movement events in NCurses, and if there is a way to catch them. Following the Interfacing with the mouse (from the NCurses programming HOWTO) it seems that by enabling the REPORT_MOUSE_POSITION bit in the call to mousemask , one can indeed catch mouse movement events. So, I tried that and it does not seem to work. I have something like this: int ch, count=0; mmask_t old; initscr (); noecho (); cbreak (); mousemask (ALL_MOUSE_EVENTS | REPORT_MOUSE

Using GNU Readline; how can I add ncurses in the same program?

问题 The title is a bit more specific than my actual goal: I have a command-line program which uses GNU Readline, primarily for command history (i.e. retrieving previous commands using up-arrow) and some other niceties. Right now the program's output appears interspersed with the user's input, which sometimes is OK but the output is asynchronous (it comes via a network connection in response to the input commands), and that gets annoying sometimes (e.g. if lines are output when the user is typing

问题 Having a Qt and ncurses based application, what is the best way to refresh the screen every second, while waiting for user input? (e.g. show the clock and get user input). I need the best compromise between CPU usage and application responsiveness. To be more specific with the question, how to get user input and still use QTimer and the signal-slot mechanism? When using the code below, the timers doen't work. nodelay(stdscr,true); while(1) { sleep(1); getch(); processInput(); } 回答1: Use

问题 I want to add str "#" in ncurse screen,with coordinate x(5 to 24) , y(23 to 42) which is a square. But I can't figure out a simple way to do it. I've tried: stdscr.addstr(range(23,42),range(5,24),'#') But this can't work. It needs 'integer'. Does anyone can figure out an easy way to do this Job? Thanks. 回答1: First two arguments of addstr should be row, col as integer but your are passing list: To make square to like this: for x in range(23,42): # horizontal c for y in range(5,24): # verticale

How to refresh curses window correctly?

由 ≡放荡痞女 提交于 2019-12-14 00:18:47
问题 while 1: ... window.addstr(0, 0, 'abcd') window.refresh() ... window size is full terminal size, big enough to hold abcd . If 'abcd' is modified to shorter string like 'xyz' , then on terminal I will see 'xyzd' . What exactly I am doing wrong? 回答1: addstr() only prints the string you specify, it does not clear the following characters. You will have to do that yourself: To clear characters until the end of the line, use clrtoeol(), To clear characters until the end of the window, use clrtobot

问题 EDIT: Getting negatives for such a detailed and HONEST question? Sometimes I don't really get Stack Overflow. Really. Hi, I'm trying to create a PoC using Swift 5 (Xcode 10.2.1) and a modern rendition of ncurses (in this case, MacPorts' one, some 6.1.2018XXXX version) My Poc has no code as of now, as my problems start before being able to add any sensible line to my .swift files. So far I've done the following things: 1.- I have a proper working MacPorts ncurses library installed: that means

问题 I am using Ncurses library to do some interactive menus, and I don't know how to do one thing. I have simple menu with few options, I turned of O_ONEVALUE so many options can be selected at the same time, before posting menu I get all the menu items and mark them as selected or not, depending on a bit mask that I keep stored somewhere else, but when the menu is posted every option is turned off, here is the code: //acquiring menu items ITEM** header_items = menu_items(params.header_opts_menu)
