Member Data Documentation

keycode

KeyboardCode keycode {EKEY_UNKNOWN}

Key code value.

This is basically the physical key that was pressed.

Any idea of a scancode or keysym is handled by the input backends themselves, which truly represent physical keys and are used for mappings.

state

KeyState state {}

Key state.

A bitmask of key modifiers such as SHIFT, CONTROL or LOCK keys.

unicode
