ncures 中的颜色对在类中无法正常工作

我正在用ncurses制作一个基本的终端应用程序引擎。我创建了一个基本的窗口类，它存储您正在使用的窗口，并允许您在其上编写。现在，我正在做一个 ColorWindow 类，它继承自 BasicWindow，应该允许你用颜色编写。根据抽象，我正在初始化类的方法之一中所需的颜色对，这是示例代码：

编辑：我在这里写所有代码

#include <ncurses.h>
#include <unistd.h>
#include <signal.h>
#include <stdio.h>
#include <string.h>
#include <iostream>
#include <iomanip>
#include <locale>
#include <sstream>
#include <string>
class ColorWindow : public BasicWindow {
private:
    int npairs;
    bool canColor;
    void initializePairs() {
        init_pair(1, COLOR_RED, COLOR_BLACK);
        init_pair(2, COLOR_GREEN, COLOR_BLACK);
        init_pair(3, COLOR_YELLOW, COLOR_BLACK);
        init_pair(4, COLOR_BLUE, COLOR_BLACK);
        init_pair(5, COLOR_MAGENTA, COLOR_BLACK);
        init_pair(6, COLOR_CYAN, COLOR_BLACK);
        init_pair(7, COLOR_WHITE, COLOR_BLACK);
        npairs = 8;
     }
   public:
    ColorWindow() {
        if(has_colors()) {
           initializePairs();
           this->canColor = true;
        }
        else {
           this->canColor = false;
        }
    }
    ColorWindow(int he, int wi, int stx, int sty) : BasicWindow(he, wi, stx, sty) {
         if(has_colors()) {
             initializePairs();
             this->canColor = true;
         }
         else {
             this->canColor = false;
         }
     }
    int addColorPair(int foreground, int background) {
         if(foreground < 0 || foreground > 7 
              || background < 0 || background > 7)
              return -1;
         init_pair(npairs, foreground, background);
         npairs++;
         return npairs-1;
    }
    bool ColorWindow::writeStringWithColor(int x, int y,const char* message, int pair) {
        if(!isInLimits(x, y))
           return false;
        if(pair >= npairs) 
          return false;
        if(canColor)
          return false;
        wattron(getContainer(), COLOR_PAIR(pair));
        mvwprintw(getContainer(), x, y, message);
        wattroff(getContainer(), COLOR_PAIR(7));
     }
    bool changeColor(int color, int r, int g, int b) {
         if(!can_change_color())
             return false;
         if(color < 0 || color > 7 || r < 0 || r > 1000 
             || g < 0 || g > 1000 || b < 0 || b > 1000)
             return false;
         init_color(color, r, g, b);
         return true;
    }
};
class BasicWindow {
   private:
    WINDOW* container;
    int startx, starty, height, width;
   public:
    BasicWindow() {
      this->height = 20;
      this->width = 84;
      this->starty = (LINES - height) / 2;  /* Calculating for a center placement */
      this->startx = (COLS - width) / 2;
    }
    BasicWindow(int he, int wi, int stx, int sty) {
      this->height = he;
      this->width = wi;
      this->starty = sty;
      this->startx = stx;
    }
    
    WINDOW* createNewContainer() {
          this->container = newwin(height, width, starty, startx);
          wrefresh(this->container);        /* Show that box        */
          return getContainer();
    }
    WINDOW* getContainer() {
          return this->container;
    }
    bool writeString(int x, int y, const char* message) {
        if(!isInLimits(x, y))
            return false;
            mvwprintw(this->container, x, y, message);
        }

    void refreshContainer() {
        refresh();
        wrefresh(this->container);      /* Show that box        */
    }
    void destroyWindow() {
         wborder(this->container, ' ', ' ', ' ',' ',' ',' ',' ',' ');
        
         wrefresh(this->container);
         delwin(this->container);
   }
    bool isInLimits(int x, int y) {
         if(x < 0 || x >= this->width-1) {
             return false;
         }
         if(y < 0 || y >= this->height-1) {
              return false;
         }
         return true;
};

这是主要的：

 #include <iostream>
 #include <unistd.h>
 #include <ncurses.h>
 #include "windows.h"
 int main() {
    ColorWindow cw = ColorWindow(20, 80, 0, 0);

    initscr();          /* Start curses mode        */
    cbreak();           /* Line buffering disabled, Pass on
                        * everty thing to me        */
    keypad(stdscr, TRUE);
    start_color();
    WINDOW* container;
    container = cw.createNewContainer();
    cw.writeStringWithColor(0, 10, "Hello everyone in color!!", 2);
    cw.refreshContainer();
    sleep(2);
    endwin();
    return 0;
}

它初始化颜色模式，但不显示任何内容，就好像选择的对是黑黑色一样。
