curse | Basic terminal cursor manipulation | Command Line Interface library

The program is printing at the lower-right corner of a window and returns an error because it cannot wrap (or scroll up).

The addch manpage says

• If scrollok is not enabled, writing a character at the lower right margin succeeds. However, an error is returned because it is not possible to wrap to a new line

and scrollok (which is false unless explicitly set):

The scrollok option controls what happens when the cursor of a window is moved off the edge of the window or scrolling region, either as a result of a newline action on the bottom line, or typing the last character of the last line. If disabled, (bf is FALSE), the cursor is left on the bottom line. If enabled, (bf is TRUE), the window is scrolled up one line (Note that to get the physical scrolling effect on the terminal, it is also necessary to call idlok).

The Vue-multiselect control allows the user to select items from a list, or type a value and press enter to select it.

The result is a "tag" for each of the selected items is added to the input box.

To select by typing, this is how it can be done on the demo page

An array containing the six characters \u4e09 is an array containing six characters, just as an array containing a backslash followed by an n is an array of two characters, not a newline. The compiler converts escape sequence in literals. Nothing (except what you yourself write) does anything to character arrays.

So your array wcsarr is not a single wide character. It's a (null-terminated) wide string using six wchar_t values to encode six ascii characters. setcchar requires that its second argument contain only one spacing character (possibly followed by several non-spacing combining characters), and your program does not conform to this specification.

You could do something like this:

The problem lies in the fact that you don't remember the Entry widgets. You just store them to a local variable in function enchwind() and don't store them anywhere. They are created but you lose all reference.

You could use a list as an attribute of window to store them:

In the definition of your window, add the line:

From the comments above:

It is the overflow-x on .bg-gray. If you remove that the image extends beyond the parent element as you desire. I'm looking for other solutions in place of the overflow property.

overflow-y: visible; will allow your image to overflow, auto will contain any elements and create scrolling when necessary. Since this is negative margin it does not create a scroll.

Without the overflow-y your background image does not appear because you have floated all of the children and therefore .bg-gray, aka .row1 has no height.

For column layouts you should look up the more modern approach of using flexbox. Remove your floats and add display: flex; to .col

CSS

As mentioned in the comments:

1. I could obtain the same result in a simpler way by writing the output to log files and using tmux;

2. In case one wanted to stick to the 'manual' approach, the problem seems to be that the various processes are interfering with each other, so the screen gets overwritten by each of them.

I solved it by collecting all the output of each process in an array, which is then sent back to the main process through queues and printed there.

PROCESS_01

The colors are maintained/cached/whatever by a given terminal.

If the terminal description has this feature:

I just figured it out myself:

dup2() creates a duplicate of the connection's file descriptor into STDIN_FILENO, leaving it open only in stdin after close(), thus reading stdin with getch, getchar or any other functions was basically waiting for the client to send something.

Removing both solved my problem: getch() now works properly.

The error is normal, if you dont have reasons to rename the directory or file because the filename is ok and no character to modify, the name stays same, so an error is displayed saying you cant rename a file/directory with same name.

Despite this error, the process is not stopped and has no impact on the final result

i suggest you to set all couple key to search , new value in an object:
