Function ncursesw::mvwadd_wch

pub fn mvwadd_wch(
    handle: WINDOW, 
    origin: Origin, 
    wch: ComplexChar
) -> Result<(), NCurseswError>

Paint a complex character wch at origin, overwriting any character previously painted at that location.

Writing outside the window, sub-window, or pad raises a NCurseswError. Attempting to write to the lower right corner of a window, sub-window, or pad will cause an NCurseswError to be raised after the character is printed.
