[−][src]Function ncursesw::define_key
pub fn define_key(
definition: Option<&str>,
keycode: KeyBinding
) -> Result<(), NCurseswError>
Permits an application to define keycodes with their corresponding control strings, so that the NCurses library will interpret them just as it would the predefined codes in the terminfo database.
If the given definition
is None
, any existing definition for
the keycode is removed. Similarly, if the given KeyBinding::Unknown
is negative or zero, any existing string for the given definition
is removed.
