Function Documentation
◆ libinput_event_keyboard_get_base_event()
| struct libinput_event * libinput_event_keyboard_get_base_event | ( | struct libinput_event_keyboard * | event | ) |
- Returns
- The generic libinput_event of this event
◆ libinput_event_keyboard_get_key()
| uint32_t libinput_event_keyboard_get_key | ( | struct libinput_event_keyboard * | event | ) |
- Returns
- The keycode that triggered this key event
◆ libinput_event_keyboard_get_key_state()
| enum libinput_key_state libinput_event_keyboard_get_key_state | ( | struct libinput_event_keyboard * | event | ) |
- Returns
- The state change of the key
◆ libinput_event_keyboard_get_seat_key_count()
| uint32_t libinput_event_keyboard_get_seat_key_count | ( | struct libinput_event_keyboard * | event | ) |
For the key of a LIBINPUT_EVENT_KEYBOARD_KEY event, return the total number of keys pressed on all devices on the associated seat after the event was triggered.
- Note
- It is an application bug to call this function for events other than LIBINPUT_EVENT_KEYBOARD_KEY. For other events, this function returns 0.
- Returns
- The seat wide pressed key count for the key of this event
◆ libinput_event_keyboard_get_time()
| uint32_t libinput_event_keyboard_get_time | ( | struct libinput_event_keyboard * | event | ) |
- Note
- Timestamps may not always increase. See the libinput documentation for more details.
- Returns
- The event time for this event
◆ libinput_event_keyboard_get_time_usec()
| uint64_t libinput_event_keyboard_get_time_usec | ( | struct libinput_event_keyboard * | event | ) |
- Note
- Timestamps may not always increase. See the libinput documentation for more details.
- Returns
- The event time for this event in microseconds
