Ncurses split window. You don't have two windows, you only have one.

Ncurses split window The window which you are moving using mvwin overlaps with stdscr. – Even more strange, I replaced logger. Make sure to call refresh() directly after an endwin() call before using other ncurses functions. Unfortunately Windows doesn't do a whole lot to make the process easier. It checks the given window and updates only the portion which has been changed. 4. Maybe you could find some tips. Replace that call with. I am using the ncurses library to write a console application. It will display to the user a single source file at a time. I mean something like this: ┌────────────────────┐ │ │ &lt;- color 1 │ │ &lt;- color 2 └──────── Ncurses with box-drawing characters I am using wsl 2 in windows 10, and i am using windows terminal the question's title tells my problem #include <ncurses. . ncurses applications normally handle SIGWINCH and use the ioctl with TIOCGWINSZ to obtain the system's notion of the screensize. I was expecting ncurses to automatically handle these low-level details. But when I'm using wprintw() I can't see any output on the screen. NOTE: The ncurses lib is terribly unsafe and ncurses-rs is only the lightest wrapper it can be. I think the main Problem is that you did refresh() the whole screen, when refreshing the window wrefresh (my_win) would have been enough. The window is now in two places, sub_win and in the num_wins array. a static library. Use wgetch(win). newpad(40,60) mypad_pos = 0 mypad. e. xterm on KDE, for example. A "window" in ncurses is a rectangle within an existing terminal that can be updated/refreshed independently. How can I prevent this behavior from happening? What is causing them to conflict? ncurses two windows side-by-side. window = window: self. So you need to pick one of these. The window is at position (begin_y, begin_x) on the screen. The (n)curses function newwin allocates space for a WINDOW structure and returns that. What I am trying to do is move the cursor to the window "window" and print the result of the command "make main. 7 (patch 20090207). (curses. , UTF-8), but it's I'm trying to create a split screen terminal application. Hector Aurelio Hector Aurelio. You have seen the standard window stdscr above where all the functions implicitly operated on this window. In this section, I’ll walk you through the steps to split your screen on Windows 11. Finally, the getch call refreshes (i. split-pane=split-window command-alias[1] splitp=split-window command-alias[2] "server-info=show-messages -JT" command-alias[3] "info=show The original question was whether there is an alternative to curses on Windows. in the while loop 2. This implementation is ''new curses'' (ncurses) and is the approved replacement for 4. For a dynamic array, you will want WINDOW** windows;. And the pointer program points to some invalid data. c++; ncurses; Share. 💻ncurses for MS Windows Command-Line. getch()in the while loop is enough. A window may be as large as entire stdscr or as small For starters, ncurses is a wrapper for the complex terminfo detail that abstracts away the particulars of each terminal type such that you can manage input/output. To decide, I am trying to familiarize myself with ncurses: I don't really understand the utility of windows (the concept in ncurses, not the OS). But if I was The scrollok()-enabled window functions until you get right down to the last line of text. refresh(mypad_pos, 0, 5, 5, 10, 60) Then you can scroll by increasing/decreasing mypad_pos depending on the input from window. This document describes how to use the curses extension module to control text-mode displays. The normal way to get a curses-alike on Windows is to use PDcurses, which has most of curses' functionality. But then the window is totally removed right? I want the window to be there. ) OK with window. Release, and Windows will automatically suggest other open programs to fill the remaining space. Kuchling, Eric S. h> int main() { initscr(); int I want to make a menu with ncurses. getch() operates on stdscr, so that is your problem. g. Split view in console. That's the only sane way I got my python program to re-size the terminal by doing a couple of things. Then, drag the window to the left or right edge of your screen. char theplayer(); char theenemy(); are an obsolescent feature of C, that say these functions will take an unspecified but fixed number of arguments. gz $ cd PDCurses-3. getmaxyx() screen. That is part of it: usually one makes persistent borders by creating a window, drawing a border on that, and make a subwindow enclosed within the first window (not touching the borders) and draws on the subwindow. ncurses takes care of detecting the new size automatically. Using stdio the terminal simply scrolls the contents. The ncurses-examples include some programs which do this (some have screens which create a succession of nested subwindows, all with their Since ncurses doesn't support Windows, you need PDCurses instead. Second Problem: you did wait for a keystrke twice: 1. If you don't refresh the screen before refreshing the window, you never get to see your window. I'm running a multiprocessing system in Python, and I was planning to use curses to divide the terminal window in 4 quadrants, and display the output of each of the processes in one of them. To start, these function declarations. So I want to split the two screens with each other. Let's say I have a background window and a foreground window. I suspect you do not actually have a static version of the ncurses library i. That means, don't call wresize(). To demonstrate, let me define a game board in an unexpected way. I tried this in the makefile: chtype is an unsigned integer, which can contain both a character and video attributes (bold, underline, reverse, blink) as well as color. The panel library is designed to solve this problem nicely, but as a workaround, If the user can execute arbitrary programs in the window, you'll want to be careful of ncurses programs--ncurses translates the move() and printw()/addch()/addstr() commands into the appropriate console codes, so blindly printing the output of ncurses programs will stomp your program's output and ignore your window location. The ncurses library emulates the curses(3X) library of Regarding the disappearing window (likely reduced to 1x1, which is not "magically disappears"). How can I prevent this behavior from happening? What is causing them to conflict? Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company You can hide an existing window by touching the other windows, refreshing those other windows and not referring to the hidden window (including the use of wgetch which would refresh the window). Follow edited Sep 2, 2015 at 20:46. In python, you'd have to make a function that used inch to retrieve characters from the screen and wrote them to a file. As a special, but frequent case, getch refreshes the standard screen stdscr: If the window is not a pad, and it has been moved or modified since the last call to wrefresh, wrefresh will be called before another character is read. That may be overridden by the environment variables LINES and COLUMNS (see use_env). Just call endwin() instead. getch() in cmd: In my application I have two WINDOW objects, which bisects the terminal window, like a split-screen. I keep getting windows with the wrong number of columns for the first and final lines. Words are randomized as you can see in the code. The ncurses-examples include some programs which do this (some have screens which create a succession of nested subwindows, all with their I am making this simple program where I make a window and it using the arrow keys but cannot seem to find a solution. First, open any window you wish to use and click on its title bar. Is there any way to write anything in second window while the word is moving in different window? How to Split Screen on Windows 11. As noted, the panel library solves problems of painting and updating overlapping windows. You work on CMake Windows-based project on Windows machine through WSL. in the if statement. The size of the whole screen can be determined by The erase and werase routines copy blanks to every position in the window, clearing the screen. h from the project root. , repaints) the main window stdscr, and obscures the other windows. Here is an Ncurses provide one main window known as Standard Screen by default, defined as stdscr. You could use this to store a callback function with each panel that William McBrine is absolutely sure. Once you define a window, you don't need to track its location on the screen; you just draw to your window using Windows form the most important concept in curses. You need to use an array of WINDOW*; even though WINDOW is an incomplete type, a WINDOW* is a complete type, and so . That is because. buffer = [""] def write(self, text): lines = text. Both Windows 10 and Windows 11 have split-screen options. right_win. However, when I use nodelay(), the program exits straight away after starting in the terminal, with nothing shown at all (just a new prompt). This code will reproduce the bug: sc = curses. If you want a 1:1 port of C to Rust or you want to crank a TUI out C-style in Rust, this will probably do the trick. I want to write an application that may be called on the command line of one terminal emulator, and upon execution, the application creates a new KDE/Environment window, separate from the current terminal emulator, and on Split view in console . Improve this answer. Your choice of IDE doesn't matter. – I'm debugging a ncurses program using the gdb. So I need a way to detect resizing and redraw. 0. e Main Window. I don't need multiple windows at a time but I would like to be able to create and destroy windows for individual menus. refresh() You can return a pointer to the new window in the same way you can return any other value: Make sure your return value matches return type of your function. 9,013 20 20 gold badges 60 60 silver badges 81 81 bronze badges. You could use this to store a callback function with each panel that can resize the content. The description of inch in the python reference makes it clear that it does not work for wide characters (e. I am trying out ncurses programming in C on Linux (Mint) and am having a strange problem. However, I can't read the mouse position except when there is a corresponding click event. The main difference between stdscr and curscr versus other windows is that these are used throughout the library in a predefined manner, and cannot be freed. That function ensures that all windows are limited to the new screen dimensions, and pads stdscr with blanks if the screen is larger. The ncurses library provides a SIGWINCH signal handler, which pushes a KEY_RESIZE via the wgetch() calls. I would like to have a white window in a blue screen, and I tried it with the following code: initscr(); WINDOW *win = newwin(10, 10, 10, 1 But then the window is totally removed right? I want the window to be there. The character read will be KEY_RESIZE. refresh() # Refresh the NCurses is UNIX library, i. Solve the "word break problem" in a single line of code Is "adaptive" Wi-Fi speed a thing on The ncurses library routines give the user a terminal-independent method of updating character screens with reasonable optimization. 5-Put all my windows in an array. Having trouble with continuously reading the mouse position from a a simple c# wrapper around Thomas Dickey's Windows build of ncurses here, I can call most of the API without any issues. buffer. You can't split a window into two windows. Reading from stdscr causes it to jump up to the top of the window stack, obscuring your win. 15. I would like to display a stdout stream which quickly fills the number of available lines on the screen and starts to overflow. It doesn't rewind the file stream, nor does it require it to be rewound. 8. You don't have two windows, you only have one. The other windows When curses starts up, the screen is initially blank, but the program has to refresh (repaint) the screen to get to that point. Hello. But you prefer to use command line Picture below shows what I see when program starts: That is correct, however when I press right arrow key selector skips middle menu option and renames last one: Here's my code. Those are configured assuming a typical MinGW configuration, with the DLLs in /bin, the headers under /include and pdcurses-sys supports two flavors of PDCurses, win32a and win32. 3 content windows - LINES - 2 X COLS, inbetween the statusbar and titlebar. By Jeff Kreeftmeijer on 2023-03-19 (originally published on 2023-03-12) Updating to 3. 1 Understanding the source window. Let's say I'm running xterm or some other terminal emulator on top of some graphical X Window Environment. That is done by putting those values into specific bits of chtype. Add a I just played a little with your code. Release:. EDIT. This is a very thin wrapper around the ncurses TUI lib. But the python binding lacks that feature. I'm looking for definitive answers about scrolling methods in a window or pad using ncurses. I'd like to know how to display color text/background inside ncurses window. $ tar xzf PDCurses-3. (This position is relative to the screen, and not to the window orig. If it is, it will handle it update its window size when refreshing the screen or reading a character. Follow edited Feb 9 at 22:15. Curses is a library used for making terminal/text based user interfaces. This way, you can view and work on different windows simultaneously. See the file INSTALL for instructions on how to build and install ncurses. Searching an explanation about ncurses, I found a little tutorial showing how to initialize a custom window. Ncurses with box-drawing characters I am using wsl 2 in windows 10, and i am using windows terminal the question's title tells my problem #include <ncurses. I have positioned the cursor using wmove but the cursor remains at the top left part of the window. The purpose of the window is so that i can display a changing score. Dear friends: I want to show different interface in the split view of console window, how to set it. There are two ways to split the screen: dragging and dropping app windows on a side of the screen, or by pressing Windows + Arrow Key to snap it to the corresponding side of the screen. Add a comment | 1 Answer Sorted by: Reset to default 0 Im a noobie but this is what I would to for an app that features tabbing between windows in ncurses. I tried to enter text at the bottom of window and print it on the top. The first window holds a files names and the second window holds the extensions of the files in current directory. The main reason you may want to use windows is to manipulate parts of the screen separately, for better efficiency, by updating only the windows that need to be changed, and for a better design. lines = lines: self. You have seen the standard window stdscr used in most of the previous examples. 9. If you want a safe and idiomatic TUI library for Rust, look elsewhere. h> int main(int argc, char** argv) { Update ncurses to fix input issues on tmux 3. initscr() # Check if screen was re-sized (True or False) resize = curses. ") right_win. A. scroll it was too complicated to move the content of the window. But when I resize the window, cursor is attached to the bottom of the window and when I type the text, symbols do The use_window and use_screen functions provide coarse granularity mutexes for their respective WINDOW and SCREEN parameters, and call a user-supplied function, passing it a data parameter, and returning the value from the user-supplied function to the application. And check demos code I am trying to compile a program using ncursesw6 on windows (mingw and msys). We can use ch inside the loop to detect what key has been Curses Programming with Python¶ Author:. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company My application's user interface consists of two windows: the console (handled by ncurses) and an X11 window for graphics. 04. When I tested where the main window was changed, using is_wintouched, it returned true only after deleting the subwindow, I don't know why. tar. The source window is the window that provides you a view of the source code that the debugged program is made up of. Look into the Panels library that is part of ncurses. initscr() sc. nodelay(1) # But removing this line allows the program to run properly for angry in range(20): I think what is happening is that you have a dynamic library for ncurses but you have used the -static option which means to not use any dynamic libraries. In my test function I then call the window lines uncommented. It might be a little more work to manage multiple windows in your program, but it's the right thing to do. Moving windows in ncurses. split("\n") self. I want to prevent the C++ ncurses library from creating its own sub-window when activated. color_pair(2)) # Draw some content in each window. You switched accounts on another tab or window. This way, you can process the tab key in some way. I read : Height and width of the window. Note that there are 3 content windows, which entirely overlap each other. With panels you can attach arbitrary user data via set_panel_userptr. left_win. Now to design even a simplest GUI, you need to resort to windows. h to see which functions are implemented. The window which I have positioned below, is the prompt panel. ztdep. See the file NEWS for a release history and bug-fix notes. While the user is debugging, via next and step, CGDB will update the source file and line number to keep you informed as to where GDB is debugging. Some specific devices can be told to give this information (e. Is there a term for a solo break without the rest of Agreeing (partly) with @leonerd, ncurses will only give you those keys as they are used as modifiers to other keys (ignoring the ASCII escape character which some people confuse with the Alt key). 9/wincon/ $ make You are not supposed to mix operations on stdscr and windows created with newwin(). By the end of these steps, you’ll be able to multitask like a pro. Dismiss alert {{ message }} Instantly share code, notes, and snippets. The wgetch call repaints (and clears, on the terminal) the opening_screen, and then the mvaddstr call updates the main window stdscr. You can program this directly in Python using the excellent pywin32 package if you're already familiar with the Are there any C++ libraries similar to Ncurses, but for Windows? It seems there are no ports of Ncurses and I need a really good display system like it. They are both small, easy-to-install and easy-to-use libraries. The "first line" was just an example print. Instead, curses. It runs fine. Its tty backend uses terminal databases that don't exist on Windows. I'm sure, that stdscr overlaps these two windows. cam cam. Control characters are directly First off, a curses window doesn’t necessarily have any sort of border or decoration that separates it from the rest of the terminal. William McBrine is absolutely sure. Let‘s verify curses is available from the Python shell: >>> import curses # No errors means success! If you don‘t see any ImportError, Split screen windows ; Mouse responsive components; Text box for editing ; I only have a basic knowledge of ncurses, and I was unable to find an answer to this question in the man pages. However you could use the panels library (which is part of ncurses) to handle the windows. I am using ncurses to build my own terminal. 3 2 2 bronze badges. Ends the terminal cursor mode. one ending with a . debug("-") with window. Any suggestions? Cross-platform is a plus. win32a has better support for colors and text effects. M. Dismiss alert. Meza This project provides some minimal functionality for ncurses calls from Windows. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company I am hacking together a ncurses application which uses 5 windows: statusbar window - 1 X COLS right at the bottom of the screen. extend(lines[1:]) The use_window and use_screen functions provide coarse granularity mutexes for their respective WINDOW and SCREEN parameters, and call a user-supplied function, passing it a This repo contains a very brief and to the point tutorial of the curses (ncurses) library family, including the panel, menu, and form libraries. refresh() # Refresh the Let’s think about this scenario. I'm trying to create a split screen terminal application. Even more strange, I replaced logger. 136k Ncurses and gdb screens overlap at debug time. So, the I don't have a lot of experience with ncurses, and maybe I'm missing something, but this behaviour is completely illogical. All the inputs seem to reaching the window but there is no movement. I can try to explain the issue from the code and from the screenshot. This is a reference doc which will help you in the process of building up great interactive command line projects using the ncurses library by GNU. halfer. To make it reasonably fast, you can combine updates using wnoutrefresh for the touch'd windows and followup with a call to doupdate. Not using initscr() and proceeding to use ncurses will lead to a segmentation fault. Simply drag a window to one side of the screen until you see a shadow, indicating where it will snap into position. html for narrative descriptions of how to use ncurses and the panel, menu, and form libraries. Windows上でターミナルのウィンドウサイズを変更すると崩れる Windows版のncursesのgetmaxyx関数にバグがあるようで､ターミナルのウィンドウサイズを変更しても変更前と同じ値を返すようです A better alternative is the split-screen feature that allows you to split the Windows 10/11 screen into multiple sections. when program run and reached the breakpoint and use cont command, ncurses program gui screen overlap a gdb screen, like this picture. Why is this the case? I asked a similar question before but kno In ncurses, "windows" are a means to divide the screen into logical areas. exe. attron(curses. Does anyone know how to use ncurses without it creating its own sub-window? struct Program *Program_create() { struct Program p, *program = &p; program->window = newwin(10, 10, 0, 0); return program; } Reason for segmentation fault: Here, the structure instance p is a local variable. Is there a way for these to overlap so that an "empty character" on the foreground signifies transparency? Fill an ncurses window with a color. ncurses' handling of SIGINT takes into account the fact that some of the functions it would normally use are not safe, and it uses a different strategy when it has receive a signal (which is perhaps not 100% reliable, but an improvement). You signed in with another tab or window. Dismiss alert Your program will be sent a SIGWINCH signal when the terminal is resized. You mention an "attempt to make a new window that is of different size then the initial terminal window" -- if you mean a terminal emulator running in a windowing system like X/OSX/Windows, that is not what ncurses does. Reload to refresh your session. The window is made in the middle of the window orig, so that changes made to one window will affect both windows. 3a. While I'm comfortable using ncurses and SDL independently, I'm having trouble figuring out how to embed the SDL graphics within an ncurses window. 2. Given that you want something DOOM-like, the example here is reminiscent because of the main screen/inventory split. I've been testing ncurses, I tried doing a simple code using windows, by reading the code from the tutorials it seemed to me like calling wrefresh() was enough if changes were made just to one window. It is worth your time to invest in learning NCurses. It would be nice if there was a simple way of drawing said box outside the window, but that would be mixing stdscr and window rendering Display the current path of the laser (e. Position in ncurses a pad below a window in c++. The problem im having is that the window is not displaying. # Initialize the screen import curses screen = curses. ncurses will attempt to keep a window which has the same width (or height) as stdscr preserve that relationship when resizing, as mentioned in the manual page:. A new full-screen window is created by calling newwin(0,0,0,0). Follow asked Apr 26, 2010 at 13:20. Both pdcurses and ncurses provide a panel library. win32a is the GDI mode while win32 runs in the Windows console. I mean something like this: ┌────────────────────┐ │ │ &lt;- color 1 │ │ &lt;- color 2 └──────── A terminal multiplexer does seem like a good idea. I want to recreate the 15 puzzle in c for fun, and am debating between using the ncurses library vs trying to handle key presses and rendering myself. h and more than one color. If you do, they will destroy your screen formatting. ncurses; Share. I'm sorry I can't show you the code because I had a situation. I would like to handle key events in a centralized way. When you set the foreground and background color for a window, is there a way to fil Split screen vertically: Ctrlb and Shift5; Split screen horizontally: Ctrlb and Shift" Toggle between panes: Ctrlb and o; Close current pane: Ctrlb and x; You can achieve more complex layouts by splitting panes. Why the split line of tmux within PuTTY shows different（xxxxx， qqqqqq）in these tow cases？ If I do not set PuTTY any thing（the default "Use font encoding"）, the split line of pane shows like following: But it can't show Chinese word correctly, so I set PuTTY's Window -> Translation -> Remote character set to UTF-8. Your resize handler can loop through all of the panels calling the resize callback. Whenever you use initscr() with ncurses, it creates its own sub-window (text area in terminal). It handles multiple windows including overlaping and stacked windows easier than the core ncurses library. Panel Library; The how-to originally came with a zip-file with the sources, which seems to have been mislaid. NCurses is UNIX library, i. graphics window) Since these are bare-bones machines, I don't have X11 installed. On Windows you should use PDCurses: Download the zip file, unpack it wherever you typically put external libraries, and check the readme, which tells you the following: NCurses (New Curses) is an implementation of Curses (a play on the term cursor optimization), both of which are terminal control libraries for UNIX and UNIX-like systems. Now I have to incorporate a text field to enter your name and I want that to be resizeable as well. available for POSIX UNIX-es like Linux, FreeBSD, MacOS X etc. These are managed by ncurses. is_term_resized(y, x) # Action in loop if resize is True: if resize is True: y, x = screen. h> int main() { initscr(); int Everything you printed is in win, but getch() reads from stdscr (the default full-screen window). Now I'm implementing the part of my app which is like a file manager. Step 1: Drag a Window. curses (the underlying library) has scr_dump for this purpose. I'm using mvwsacanw to write the word. *(num_wins + i*4+j) = *sub_win; Here you copy a window. If I shorten the scrollok()-enabled window it does not line up to the status bar properly and there is always an extra blank line of text on the terminal window. The exact nature As noted, the panel library solves problems of painting and updating overlapping windows. And use ‘putc();’ or ‘printw(“%c”, ch);’ to print chars inputed. There are utilities like vcpkg that take a lot of the pain out but they aren't installed by default and isn't taught in any programming class I've ever seen. Installing the toolchain, plus including the ncurses directory during compilation, plus statically linking some libraries the executable couldn't find seems to have done the trick. I figured that perhaps I could use ncurses to develop a cross-platform interface to configure the settings for the laser, and use SDL to draw arcs and lines to represent the path of the laser. Now to make design even a Tell the curses system to dump the contents on the given window. changes to the inner box have no effect on the box; there is a function box which draws a box along the edges of a given window. 1-Implement function that reads charactors and processes them 1 by 1 with ‘noecho();’ using ‘getch()’. Windows 10 and Windows 11 have a split screen feature that allows you to use multiple apps simultaneously by pinning them to different areas of the screen. It also allows you to make windows that divide the stdscr i. ncurses can be compiled to handle this itself. I did this. GNU screen is in fact emulating its own terminal, that is, parses escape sequences, executes their logic, builds an internal representation of the screen, and then transfers that on whatever terminal it's running on. The usual reason for this problem is that running wgetch on a window does a corresponding wrefresh on the same window. Contribute to ldm0/wncurses development by creating an account on GitHub. This extension module is designed to match the API of ncurses, an open-source curses library I am using ncurses for a terminal application which should also be usable on windows but every time the user resizes the terminal everything is mashed. With this, the compiler cannot reason about what an invocation of these functions should look like. Default operation seems to be non-blocking (or have I missed some initialization)? I would like it to work like getch() in Windows. Fortunately, ncurses provides the ability to split these two concerns into separate windows, each updated independently. On Windows, you could use it under a unix-like environment such as Cygwin or MSYS2, but you would hardly want to go to that length merely for the sake of writing What if the user hit ESC and then another key like [for example, really fast one after another, couldn't our code see both keys coming through and then it would not exactly look like an ESC?Because I don't really see how the terminal would know that on my second call to gather the next character that I'm trying to determine whether just ESC was hit?! That looks as if you downloaded one of the sample cross-compiled builds from the ncurses homepage. ncurses multi colors on screen. That is, no matter which of the two windows is active, the same event loop should handle all the key events. I would like text to be entered there and as well I want the ability to input text in there. So you can use it if you're writing C on a unix-like OS (such as Linux). – You cannot allow the subordinate programs to emit their own escape sequences. And check demos code Ive tried looking for a solution, i just don't know why the window is not displaying. One answer is to use the Win32 console API. If you are on Windows, use the PDCurses port. resizeterm(y, x) screen. ncurses is a text-based graphics library for C that is supported on unix-like OSes, not on Windows. The simplest way to retain a box around a window is to create the box in a window which surrounds it. How can I avoid this overlapping? Maybe I need to use wrefresh() or refresh()?I've tried, but it doesn't help. Although on Windows, you can already use cmake-gui. There is PDCurses which support Windows, and you can replace ncurses with PDCurses in your program and use it with POSIX and another systems like DOS, Windows etc. I found the solution myself: refresh win after stdscr. But with ncurses as far as I understand the output is only limited to I've written a curses program in python. If ncurses is not compiled with this feature, you need to handle SIGWINCH yourself wincurses (An ncurses implementation for Windows terminals) Justin J. As a side note, ncurses is not thread I see my problem, I was creating a subwindow when I need to create a new window. Then it clobbers my status bar: it disappears forever. This describes ncurses version 5. ncurses is supported as of 5. I already have an event loop for X11 events. 4BSD classic curses, which has been discontinued. asked Type layout as a command in gdb and the split window will be shown. The clear and wclear routines are like erase and werase, but they also call clearok, so that the screen is cleared completely on the next call to wrefresh for that window and repainted from scratch. If you copy the window structure, you need to use one and only one instance to refer to the window.

If you're using MSVC or another compiler, I think Although it is quite likely that you would be better off serialising the state of the game which produces the window rather than the window itself, there is no problem using putwin and getwin to serialise and retrieve an ncurses Window. This structure instance (p) gets removed, after we return from the function. After extracting the source tarball, cd into wincon/ and run make, which produces pdcurses.
