Struct EventDecoder

Source 
pub struct EventDecoder<L>
where
    L: KeyboardLayout,
{ /* private fields */ }
Expand description

Converts KeyEvents into Unicode, according to the current Keyboard Layout

Implementations§

Source§

impl<L> EventDecoder<L>
where L: KeyboardLayout,

Source

pub const fn new(layout: L, handle_ctrl: HandleControl) -> EventDecoder<L>

Construct a new event decoder.

Source

pub fn set_ctrl_handling(&mut self, new_value: HandleControl)

Change the Ctrl key mapping.

Source

pub const fn get_ctrl_handling(&self) -> HandleControl

Get the current Ctrl key mapping.

Source

pub fn process_keyevent(&mut self, ev: KeyEvent) -> Option<DecodedKey>

Processes a KeyEvent returned from add_bit, add_byte or add_word and produces a decoded key.

For example, the KeyEvent for pressing the ‘5’ key on your keyboard gives a DecodedKey of unicode character ‘5’, unless the shift key is held in which case you get the unicode character ‘%’.

Source

pub fn change_layout(&mut self, new_layout: L)

Change the keyboard layout.

Only useful with layouts::AnyLayout, otherwise you can only change a layout for exactly the same layout.
