ncurses library

Just a concept CLI (UI)

Discovering the ncurses library uses in c++. Here's a shell of a window program. This one has five panels (forms) selected by pressing the [HOME] key - (which opens yet another form - small centered dialog). I haven't decided what to do with it yet. I'm just learning the interface design.

Terminal Colors 

Changing terminal output colors with an easy function.

I had a hard time adjusting to using ncursers and conio in Linux, so I just wrote my own color map. It resembles the Borland VCL color consts that I'm so used to.

Sample program and color.h shown below:

main.cpp

#include <iostream>

#include <stdio.h> 

#include <cstring> 

#include "color.h"

 using namespace std;

 

 int main()

 {

 string s = "Demo colors on terminal output.";

  cout << SendColoredText(clMAROON, clWHITE, s) << "\n";

  cout << SendColoredText(clBLACK, clOLIVE, s) << "\n";

  cout << s << " (default)\n";// default terminal colors

  cout << "\e[3m\e[4m" + SendColoredText(13, 9, s) << "\n\n";//italics + underlined

 return 0;

 }
