在屏幕上获取字符 [英] get char on screen

问题描述

我查看了 NCurses 函数列表，但似乎找不到返回已打印在屏幕上的字符的函数.每个字符单元格中存储的字符是否有可访问的值?如果没有，Windows终端有没有类似的功能?

I've looked through the NCurses function list, and I can't seem to find a function that returns the characters already printed on the screen. Is there an accessible value for the char stored in each character cell? If not, is there a similar function in the Windows terminal?

我想用它来用不同的字符或新的属性替换屏幕上某个值的所有字符(例如:所有 a's).

I want to use this to replace all the characters on the screen of a certain value (ex: all the a's) with a different character, or with new attributes.

推荐答案

函数 inch() 获取字符并将其作为 chtype 返回.使用 winch() 从除 stdscr 之外的窗口获取字符.

The function inch() gets the character and returns it as a chtype. Use winch() to get a character from a window other than stdscr.
