c++ - 使用 WriteConsoleOutputCharacter 和 SetConsoleTextAttribute

Question

我正在尝试编写一个通过坐标输出的程序。我正在使用 windows.h 包含和函数 WriteConsoleOutputCharacter 将字符打印到屏幕上，但是它忽略了 SetConsoleTextAttribute 设置的颜色。有什么想法可以让它以彩色输出吗？

代码输出到控制台:

void Card::printFancy(COORD coord, bool top) const
{
    paint();
    LPDWORD written(0);
    for (int row(0); row < CARD_WIDTH; ++row)
    {
        coord.Y += 1;
        WriteConsoleOutputCharacter(Colorizer::getInstance().getCon(), _card[row], CARD_WIDTH, coord, written);
    }
    unpaint();
}

并且 paint 基本上使用适当的颜色在我的 Colorizer 类中调用一个 paint 函数Colorizer 绘制函数(由 paint() 和 unpain() 调用):

void paint(uint color)
{
    SetConsoleTextAttribute(_con, color);
}

_con 是句柄，通过_con = GetStdHandle(STD_OUTPUT_HANDLE);设置

根据 Hans Passant 的建议在 https://stackoverflow.com/a/9275247/15485您可以将 WriteConsoleOutputCharacter 与 WriteConsoleOutputAttribute 匹配。

#include <windows.h>
#include <stdio.h>

void write_symbol_in_color(HANDLE h, SHORT x, SHORT y, const char* symbol, WORD color)
{
   COORD here;
   here.X = x;
   here.Y = y;

   WORD attribute = color;
   DWORD written;
   ::WriteConsoleOutputAttribute(h, &attribute, 1, here, &written);
   ::WriteConsoleOutputCharacterA(h, symbol, 1, here, &written);
}

int main()
{
   HANDLE hStdOut = ::GetStdHandle(STD_OUTPUT_HANDLE);
   if (hStdOut == INVALID_HANDLE_VALUE)
   {
      printf("Invalid handle");
      return 1;
   }

   write_symbol_in_color(hStdOut, 0, 0, "R", FOREGROUND_RED | FOREGROUND_INTENSITY);
   write_symbol_in_color(hStdOut, 1, 0, "G", FOREGROUND_GREEN | FOREGROUND_INTENSITY);
   write_symbol_in_color(hStdOut, 2, 0, "B", FOREGROUND_BLUE | FOREGROUND_INTENSITY);
   write_symbol_in_color(hStdOut, 3, 0, "C", FOREGROUND_GREEN | FOREGROUND_BLUE | FOREGROUND_INTENSITY);
   write_symbol_in_color(hStdOut, 4, 0, "M", FOREGROUND_RED | FOREGROUND_BLUE | FOREGROUND_INTENSITY);
   write_symbol_in_color(hStdOut, 5, 0, "Y", FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_INTENSITY);

   return 0;
}
