Hi all

I am writing a displayer class to adapter with ncurses's WINDOW* ,
when I use vs << KEY_BACKSPACE, I want delete a char.(just current line
maybe)

Do I have to write some bufferFrame to achieve that?

thank you very much.

You can delete a char by writing a space.

or delch()

It depends on what OP means by "delete a char".
