SetCurrentConsoleFontEx 使文本加粗

Question

I'm trying to make a function (in C++) that uses the WinAPI to make something that resembles a "header" in the console. By "header," I simply want the text to be another color and bold. I'm able to change the color, but bolding the text is proving frustrating.

I've read mixed answers about making text bold using the SetCurrentConsoleFontEx() ; some people say it's possible while others have said it's not (in a not very straightforward way). I came across a comment on this question that said bolding and color change can be applied to an individual character.

Here's what I'm trying. This code is simplified, of course.

auto errormsg = []() { std::cout << "\nError!\n" << std::endl; };

HANDLE h = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_FONT_INFOEX font_info = { sizeof(font_info) };

try
{
    if (!GetCurrentConsoleFontEx(h, false, &font_info)) throw;
    auto old_font = font_info;

    font_info.FontWeight = FW_BOLD;
    if (!SetCurrentConsoleFontEx(h, false, &font_info)) throw;

    if (!SetConsoleTextAttribute(h, /* A short for color ID */)) throw;

    std::cout << /* Header text here */ << std::endl;

    // Restore old font and old font color...
}
catch (...)
{
    errormsg();
    exit(1);
}

Although I'm using C++ functionality here, I'm okay with a pure C solution; I prefer whatever is simplest, of course.

Edit
To clarify, the problem is when I restore the old font stuff, the entire console window is reverted back. I obviously don't want this to happen.

Answer 1

This is the default behavior of the console.

If you want to support bold fonts by different in the console window, you may need to submit the feedback via feedback hub.
