更改命令提示符文本大小C ++ [英] Changing Command Prompt Text Size C++

问题描述

我用C ++开发了一个控制台应用程序，该应用程序只能在Windows上运行.我想在程序运行时更改命令提示符的文本大小.我进行了一些搜索，但是找不到任何可以解决该问题的方法.每个人都在谈论改变颜色.

I developed a console application in C++ that will run only on Windows. I want to change Command Prompt's text size when the program runs. I did some search but, I could not find anything that would solve the problem. Everybody is just talking about changing the color.

无论如何，如果可能的话，如何更改命令提示符的文本大小.

Anyway, if this is possible, how can I change the text size of Command Prompt.

谢谢！

推荐答案

在获取当前字体信息之前，必须使用sizeof(CONSOLE_FONT_INFOEX)初始化CONSOLE_FONT_INFOEX结构.
另外，您必须仅使用可用尺寸:

You have to initialize CONSOLE_FONT_INFOEX structure with sizeof(CONSOLE_FONT_INFOEX) before getting current font info.
Also you have to use only available sizes:

• 4 x 6
• 16 x 8
• 6 x 9
• 8 x 9
• 5 x 12
• 7 x 12
• 8 x 12
• 16 x 12
• 12 x 16
• 10 x 18

BOOL SetConsoleFontSize(COORD dwFontSize){
    HANDLE output = GetStdHandle(STD_OUTPUT_HANDLE);
    CONSOLE_FONT_INFOEX info{sizeof(CONSOLE_FONT_INFOEX)};
    if (!GetCurrentConsoleFontEx(output, false, &info))
        return false;
    info.dwFontSize = dwFontSize;
    return SetCurrentConsoleFontEx(output, false, &info);
}
